03B487AE2B23FFDFF7C3FCC3FAA0F877.taxon	discussion	Comments. This subfamily / tribe was initially described as a subfamily of Mimnermidae (= Anostostomatidae), including only Lutosa (Gorochov, 1988). Johns (1997), defined the family Anostostomatidae and divided it into two subfamilies, Anostostomatinae and Deinacridinae. The subfamilies defined by Gorochov (1988), are treated mostly as tribes in Anostostomatinae. Therefore, Lutosini got its tribal status. Johns (1997) also included additional genera in the tribe, such as: Licodia, Apotetamenus, Libanasa, Papuaistus, Carcinopsis Brunner von Wattenwyl, 1888, Aistus Brunner von Wattenwyl, 1888, Spizaphilus Kirby, 1906, Hypocophus Brunner von Wattenwyl, 1888 and Hypocophoides Karny, 1930. Issa & Jaffe (1999) described Hydrolutos from the imposing Tepuis of Venezuela, this genus is remarkable for its semi-aquatic habits. In 2001, Gorochov proposed a classification for the superfamily Stenopelmatoidea and, consequently, for Anostostomatidae, giving subfamily status again to those taxa proposed by him in 1988 and adding Leiomelinae as a new subfamily. In the particular case of Lutosinae, it only maintained Lutosa, and, Apotetamenus and mentioned that Licodia might belong to this subfamily (Gorochov 2001 a). In the same year, Gorochov described the genus Neolutosa (with two species), and three Lutosa species from Brazil (Gorochov 2001 b). Derka and Fedor described additional species for Hydrolutus when exploring new Tepuis in Venezuela (Derka & Fedor 2010, 2012, Derka et al. 2013, 2016). Cadena-Castañeda & Cortés-Torres (2013) described Apotetamenus gorochovi Cadena-Castañeda & CortésTorres, 2013, and synonymized Apotetamenus politus (Bruner, 1915) under Apotetamenus clipeatus Brunner von Wattenwyl, 1888. In 2015, the location of Libanasa in Lutosinae was discussed. The difficulty of defining the subfamily due to the included taxa’s morphological variability is evidenced. It was suggested that the diversity of Neotropical taxa known at that time was reviewed to understand group’s diversification, compared to taxa from other regions of the world (Johns 1997, Johns & Hemp 2015). Heleodoro & Mendes (2016) describe Lutosa horribilis, highlighting the bad smell expelled by individuals of this species; additionally, they record the genital characteristics, this being an important piece of information to establish differences between Lutosinae taxa. Recently, new genera have been described for Lutosinae / Lutosini, such as Rhumosa, distributed in the Lesser Antilles and morphologically very similar to Lutosa (Hugel & Desutter-Grandcolas 2018). Tintiyakus was also recently described as morphologically very similar to Hydrolutos, being its Amazon lowland counterpart (Mendes et al. 2020). Finally, Gorochov (2020) proposed a new classification for the Stenopelmatoidea, which goes against his 1988 and 2001 proposals. He makes significant changes to all the taxa of the superfamily. But focusing on Anostostomatidae, he divided the family into only two subfamilies, Lezininae and Anostostomatinae; in the latter, he included all those subfamilies that he proposed in the past under tribe status, and thus Lutosinae become the tribe Lutosini.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B22FFD9F7C3FF16FDAFFE8F.taxon	discussion	Comments. This is the type genus of the subfamily or tribe Lutosinae / ini. Despite being the type genus, its status is not entirely resolved since the females of the subfamily are mostly similar. For example, the type species of the genus is Lutosa marginalis, which the type specimen is a female, from an unknown locality, thus making the comparison with other congeneric species or with those of very similar genera difficult. Pherterus Brunner von Wattenwyl, 1888 was synonymized under Lutosa. Several taxa proposed by Brunner von Wattenwyl were later synonymized to the taxa described by Walker since the first did not know the contributions of the second. In their different monographs, they coincided in the description of taxa (Cadena-Castañeda 2012). Lutosa currently includes 13 species distributed in Mexico, South America, and the Antilles; some of these little-studied species will be treated here:	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

SP: 2.3 / 1.5. Ov: 15. Comparison. Among the currently described species, this new species resembles the male of Lutosa cubaensis. L. quaresmai n. sp. differs from L. cubaensis, by the darker coloration of the body and the constant brown coloration of the body’s dorsal surface. In contrast, L. cubensis has lighter shades, and the abdomen in dorsal view has black stripes along the posterior edges of the tergites. The two lobes of the tenth tergite of L. cubaensis are narrower and the hooks thicker than in the new species. Both species do not have sclerotized plates on the posterior border of the subgenital plate. The female of L. quaresmai n. sp. is more similar to L. marginalis than to the other currently known females. The new species differs from L. marginalis by the larger size and the shape of the epiproct, wich in L. quaresmai n. sp. is a semicircle, and in L. marginalis is a hexagon. The subgenital plate in both females is triangular, but they differ, for L. marginalis, the apex is truncated, and for the new species, it is not.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

When reviewing this specimen, it fits the morphological characteristics of L. marginalis, so a redescription is very useful to define the species, and even more important to give stability to the genus, corroborating that the other known species (redefined here) are related to L. marginalis (type species). Obviously, it is still necessary to study males of this species to clear up any other doubts about the generic limits of Lutosa, but this will be feasible in the future with the locality studied here. L. marginalis is the smallest known species, in contrast to other species that can be double or almost triple its length.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B2DFFD2F7C3FBBEFA87FBDF.taxon	discussion	Comments. This species was originally described as Rhaphidophorus cubaensis Haan, 1843, based on a male from Cuba (Haan 1843). Then, Brunner von Wattenwyl (1888) moved the species to the genus Pherterus and recorded additional specimens from Port-au-Prince (Haiti), Bahia, and Brasília (Brazil). Other authors provided additional records from Grenada, Saint Vincent (Richmound Valley), Dominica, Guadelupe (Trois Rivieres) and Colombia (Brunner von Wattenwyl & Redtenbacher 1892, Bruner, 1893, Caudell 1915, Karny 1927). Kirby (1906), moved this species within Lutosa, once he synonymizes Pherterus. For us, misidentifications were historically made and there are doubts about the definition of this species. Other specimens outside of Cuba were identified as L. cubaensis, and these may belong to other species. For example, specimens from the Lesser Antilles may belong to Rhumosa, this had already been mentioned by Hugel & Desutter-Grandcolas (2018), suggesting that the specimens reported from Saint Vincent could be Rhumosa captainblighei Hugel & Desutter-Grandcolas, 2018 and those recorded from Grenada and Trinidad could be other undescribed species. We agree with what was proposed by Hugel & Desutter-Grandcolas, and add that the specimens from Dominica would belong to Rhumosa macoucheriei Hugel & Desutter-Grandcolas, 2018, and those from Guadalupe can be Rhumosa bolognei Hugel & Desutter-Grandcolas, 2018. Those from Colombia could be true Lutosa or a morphologically similar genus, but this hypothesis cannot be yet corroborated since the specimens of L. cubaensis, recorded from other localities, are predominantly females, in the same way as those recorded for Colombia and Brazil. It is necessary to have males to verify and differentiate the genera. However, as we can see at the end of this contribution, Lutosa has a distribution in South America, mainly in the Atlantic Forest. Since the description of L. cubaensis, no additional specimens have been recorded from Cuba, but there are species of Licodia from the Greater Antilles, for example Licodia cerberus Rehn, 1950, and from Haiti, Licodia grandis Rehn, 1930. Possibly, the specimens determined as L. cubensis recorded from these localities may be conspecific to the Licodia species since the records are based on females, which can be easily confused with the other Lutosini taxa. Confirmation of what was previously mentioned can be seen with the specimens observed by Gundlach (1891) in Cuba. He indisputably describes specimens of Licodia, mentioning macrocephalyzation (absent in the male type specimen of L. cubaensis), among other characteristics that resemble L. cerberus or a close species (Gundlach 1891). After verifying the Lutosa species in this paper, and observation of the type specimen based on photographs generously shared by Luc Willemse, the holotype male fits the morphological characteristics of South American males of the genus, and most likely, it is a mistaken locality. The species probably is not found in the Caribbean, and it is actually distributed in Brazil. The males here reported from Bahia and Brasília fit the morphological characteristics of the holotype, perhaps completely ruling out the presence of the genus in the American insular area.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

However, the data was never published. Two females of the original syntypic series was labeled by Hubbell as “ (Not) Pherterus goeldianus ” (Hollier 2011), suggesting that these speciemens do not belong to L. goeldianus and we agree. Reviewing the photographs of all types, for us, these females belong to an unknown species. Despite the labels fixed by Hubbell indicating paratypes and a allotype (Hollier 2011), these categories of non-bearing-names types cannot be designated posteriorly, derived from a syntypic series. According to the Zoological Code (Ride et al. 1999), after 2000, only lectotypes and paralectotypes can be designated from a syntypic series and must be designated by the first reviewer. Posteriorly, Karny (1935), recorded a male from Hansa, Santa Catarina and a female from Espírito Santo (Brazil). We also disagree with the hypotesis that this species is a synonym of L. marginalis, as suggested by Kirby (1906). When comparing both female type specimens, differences in the structure of the subgenital plate are evident as indicated in the redescriptions previously provided.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B33FFC9F7C3F992FCB7FE47.taxon	discussion	Comments. It is worth noting that in the original description of L. paranensis only the male is described. Unfortunately, nether the presence nor absence of the tympana in the fore tibiae nor the structures of the terminalia are mentioned. However, in an exchange of messages a few years ago with Jason Weintraub (ANSP curator), the absence of tympana to the type specimen was revealed. (This afirmation is confirmed by Tony Robillard, who very kindly sent us some additional images from the holotype in 2022). On the other hand, L. surda is described based on a female without tympana. When comparing with both specimens and with the Morselli’s unpublished thesis (2010), we conclude that the type specimens of both species are conspecific. Morselli studied and identified males and females as L. surda n. syn., which fit in the morphology of L. paranensis, the older name. In MNHPY, there is a female (Fig. 10) with the same data presented by Rehn (1911) in the original description of L. paranaensis (Paraguay, Puerto Bertoni), also with the same collection number “ 410 ” as the holotype male, which suggests that they were collected at the same time. The female examined fits the characters of L. surda n. syn., as occurs with the males and females studied by Morselli (2006, 2010), supporting our hypothesis of synonymy between both species. Additionally, one of the labels of the holotype of L. paranaensis indicates that the collector was Schrottky (Curt Schrottky (1874 – 1937 )), a Russian entomologist who resides in South America, and was the son-in-law of Moisè Giacomo (Moisés Santiago) Bertoni (1857 – 1929) and brother-in law of Arnoldo de Winkelried Bertoni (1878 – 1973) (Rasmussen et al., 2009), with whom he carried out the expeditions in which the specimens of L. paranaensis were collected, and other material sent to Rehn (published in 1911). However, they always kept specimens as backup in their personal collections. For this reason, we believe Schrottky and Bertoni only collected a male and a female of the species, and sent to Rehn only the male (now holotype), keeping with them the female studied here (B. Garcete-Barrett pers. comm.). On the other hand, the type locality of the two species is the same, Puerto Bertoni (Paraguay), although it has recently been recorded for northern Argentina and Brazil (Morselli 2010, Zubarán & Braun 2018). Apparently, this species is not the only one without tympana, there are others not described with the same condition, which are distributed further north in the Atlantic Forest (Morselli 2006, 2010).	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

Three species are currently known: Licodia pallipes Walker, 1869 (Type species), L. grandis Rehn, 1930 (both from Haiti) and L. cerberus Rehn, 1930 (from Cuba). Of the three species, only the male of L. cerberus is formally known.

03B487AE2B35FFC9F7C3FE5AFD94FBFB.taxon	discussion	Comments. This species was originally described as Pherterus brasiliensis Brunner von Wattenwyl, 1888. Its description was based on a male and a female from Theresopolis, Santa Catharina, Brazil. This locality was a colony of German immigrants located at the banks of Cubatão River (and not the city of Teresópolis, Rio de Janeiro), near the capital of the state, Florianópolis. Currently, this locality is a district of the municipality of Águas Mornas (Map 1). Unfortunately, the two specimens used for the original description are lost (H. Braun comm. pers.), three specimens deposited in Vienna, identified as L. brasiliensis (two females and one male) do not belong to the specimens originally studied by Brunner von Wattenwyl (1888), they were actually later determined by Karny (1930). The brief original description indicates that the fore tibia has two spines on the outer dorsal margin and the hind tibia is curved. Specimens currently identified as L. brasiliensis in Vienna do not meet these characteristics, and for us is a misidentification. With this scenario, the type specimens are lost and providing a redescription and reliable identification is not possible at this time. Therefore, it is necessary to designate a neotype, preferably from the type locality and that fits the morphological characteristics originally described, it is not recommended to make specimens from other localities, even if the localities are close, since this is a specious genus (although many of its species are still not formally described).	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

Karny (1937) synonymized Lutosa obliqua Walker, 1869 and Glaphyrosoma aztecum Saussure & Pictet, 1897 under Licodia pallipes Walker, 1869 (Fig. 11). The type specimen of L. obliqua does not have locality information, apparently Karny was confused in 1937 and mentioned that the species came from Mexico, which is incorrect. When reviewing the type of L. obliqua, it evidently coincides with an adult female of L. pallipes, corroborating the synonymy proposed by Karny (1937) (Fig. 12). Otte (2000) perhaps overlooked some taxonomic decisions of Karny and mentioned G. azteca again, but wrongly included it in Lutosa. The type locality of G. azteca is Teapa in Mexico, and the type specimen is a female. The drawing of this specimen coincides with the subadult female of L. pallipes (Fig. 11 D), both apparently deposited at BMHN London. Saussure & Pictet (1897) possibly got confused and described the type specimen of L. pallipes as G. aztecum. However, there is a male in BMHN with the label data, as mentioned by Saussure & Pictet, in the original description of G. aztecum, and this male coincides in the morphological characteristics of Glaphyrosoma bulbosum Gorochov & Cadena-Castañeda, 2016. With the aforementioned, the confusion of the authors is evident, who included the data of this male, which is certainly a Glaphyrosoma, but ended up describing the type specimen of L. pallipes, collected in Haiti. Based on what was investigated here, there is no female type specimen that represents G. aztecum, and the male “ holotype ” is not valid because it was never formally described.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B39FFC5F7C3FA04FE91F8BD.taxon	discussion	Comments. It is proposed to move Lutosa horribilis under the genus Neolutosa. This decision is based on the structure of the male’s tenth tergite, which projects into two subtriangular lobes. Neolutosa horribilis n. comb. is different from the male of N. aculeata, since the apex of each lobe of the tenth tergite in the latter species is pointed (Fig. 13 D), in contrast to N. horribilis n. comb., which has the apex of the lobes rounded (Fig. 13 F). The male subgenital plate of the two species is similar, except that in N. aculeata it is longer than wide (Fig. 13 E), and to N. horribilis n. comb., is quadrangular, as wide as long (Fig. 13 G). The styli of both species are similar, the outer borders are straight and the inner ones progressively curved towards the apex, this character can be used as an additional generic character to those studied in the original description of the genus. The female subgenital plate of N. horribilis n. comb., is triangular-shaped, unlike N. emarginata, ruling out that the emarginate subgenital plate is a generic character.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B38FFC7F7C3FF16FEE2FD03.taxon	discussion	Comments. Possibly its type locality is wrong (Central America), Gorochov also doubts it in the original description, accompanying with a question mark (?). Gorochov (2001 b) included this species in Neolutosa, knowing only one female, which in her habitus generally coincides with the diagnosis of the genus. But the character of the emarginate female subgenital plate must be reevaluated, since some females of undescribed species of Lutosa also have the emarginate subgenital plate. We studied two females from Ilhéus, Bahia (Brazil) (Fig. 14), these females fit the diagnostic characters of the species, so we do not believe in the presence of this species in Central America. This situation probably occurred due to an error in the holotype label. For now, it is necessary to study males from the collection area of females, to fully corroborate the generic status of the species. For the females studied here, it can be confused and a reader may think that they are two different species due to the shape of the subgenital plate. However, one of the females has the subgenital plate in a normal position (Fig. 14 F), and the other female has it opened (lowered), exposing the genital chamber (Fig. 13 G). This could be confusing at first glance, and that is why we clarify it here. Specimens examined. 2 Females. Brazil, Bahia, Ilhéus. A female collected in 06 – 08. VIII. 2021 and another in 02 – 04.

This genus is found in the lowlands of South America, and groups three species: Apotetamenus amazonae Brunner von Wattenwyl, 1888 (type species, Western Amazon and Amazon foothills, between Bolivia and Ecuador), A. clipeatus Brunner von Wattenwyl, 1888 (Bolivia, southeastern Brazil and northern Argentina) and A. gorochovi Cadena-Castañeda & Cortés-Torres, 2013 (Colombia, Guainia, Amazon region) (Cadena-Castañeda & Cortés-Torres 2013, Cigliano et al. 2022) (Map 2). It is distinguished from the other Lutosinae / ini, because the pronotum is elongated, and covers the other thoracic segments, and in some specimens even the first abdominal tergites (Fig. 15 A, B). In addition, the species with known males (except A. gorochovi), has the last tergite narrow, paraprocts thick, pointed, and sclerotized, and subgenital plate without styli.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3AFFC6F7C3FF16FF27FB4D.taxon	discussion	Comments. In this contribution we report specimens from the Brazilian Amazon and São Paulo. Unfortunately, no adult males were found, only subadults, but the identification is confirmed with several adult females found in the same collections, expanding the distribution of the species to the north and east of Brazil. This species was redescribed by Cadena-Castañeda & Cortés-Torres (2013), in that same contribution Apotetamenus politus Bruner, 1915 was synonymized under A. clipeatus. The huge population collected in Macapá intrigued us once it is composed only of females. This data suggests that this particular population probably is parthenogenetic. It has been largely postulated that asexual populations are colonization linages, and usually occur where sexual populations are difficult to establish, like isolated or marginal habitats (Lorenzo-Carballa et al. 2012). The sites where this species was collected are predominantly formed by open vegetation or rightly altered forest — all the localities in Amazon region are areas of savanah or highly devasted forest areas (i. e., the locality in Paragominas is a bauxite mine). This data suggest that this kind of environment favors the stability of A. clipeatus populations or colonization. Specimens examined and new records.

03B487AE2B3AFFC6F7C3F96CFA98F834.taxon	discussion	Comments. This species was described from Chile as a variety of Pherterus cubaensis. Additional specimens have not been recorded since its description, and no additional study of the type specimen has been carried out, so the association of this species is not clarified. Johns (1997) placed this species in Dolichochaeta, since his description better fits that genus. However, Gorochov (2001 a) moved it back into Lutosa without justification, but he keeps that this species is dubious and should not be included in Lutosa. It is suggested to move the species back to Dolichochaeta, since the original description indicates characters more akin to Rhaphidophoridae than to Anostostomatidae.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3AFFC6F7C3FA1DFE91F969.taxon	discussion	Comments. This Chilean genus is currently monotypic. It only includes Dolichochaeta longicornis Philippi, 1863. Unfortunately, the type specimen is lost. Its original description indicates characteristics more akin to Rhaphidophoridae. In addition, Dolichochaeta is poorly studied and, according to Johns (1997), eight or ten species of this group of possible Chilean Macropathinae should still be described. This genus may possibly be a synonym of one of the two Chilean Rhaphidophorid genera Heteromallus Brunner von Wattenwyl, 1888 and Udenus Brunner von Wattenwyl, 1900.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3CFFC0F7C3FF5EFCDAFC07.taxon	discussion	The classification of the chevron crickets has been changing in the taxonomic ranges, and already belonged to Mimnermidae (Lezininae, Lutosinae, Mimnerminae and Deinacridinae) and Cratomelidae (Cratomelinae and Anabropsinae) according to Gorochov (1988). These two “ families ” were synonymized to Anostostomatidae. Mimnermidae became a junior synonym (a name not currently valid), and Cratomelidae was considered a monogeneric tribe in the same way as the other subfamilies that got status of tribe (Johns, 1997). Again Gorochov (2001 a) elevated to the status of subfamilies to the previously mentioned taxa, also including as a subfamily Cooloolidae = Cooloolinae, a successful change of taxonomic rank. This classification scheme in subfamilies was mostly accepted and incorporated in the Orthoptera Species File (Cigliano et al. 2022) and in which we have been following in the last twenty years.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3CFFC0F7C3FF5EFCDAFC07.taxon	description	Recently, Gorochov (2020), decided to keep two subfamilies, Anostostomatinae and Lezininae, opining that the latter should also be a tribe, since it does not have special morphological characters. The other subfamilies were treated as tribes of Anostostomatinae. Gorochov’s taxonomic rank changes were not restricted only to the Stenopelmatoidea, but also occurred in the Grylloidea and Tettigonioidea. Perhaps, Gorochov will apply the same procedure to the family Rhaphidophoridae. So, we may ask: will he rearrange camel cricket subfamilies into tribes or return to his old scheme of Ensifera subfamilies mentioned here? Undoubtedly, Gorochov has contributed enormously to the study of Ensifera and other Polyneoptera, but a fair hierarchy must be maintained for all taxa. Gorochov (pers. comm.) introduced his changes in taxonomic ranges so that they are more similar to the classifications of other groups of insects, and thus establish coherence in the taxa indistinctly. If Gorochov taxonomically reassigned subfamilies to tribes, the same should happen in groups that he considers subfamilies and that are closely related, as an example the group of subfamilies Gryllinae (more details in Cadena-Castañeda & García García 2020) among others.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3CFFC3F7C3FC76FD0EFF37.taxon	discussion	It is necessary to define the subfamily or tribe Lutosinae / ini. But, for this, it is necessary to have additional specimens from other nearby groups to corroborate the affiliation and define additional characters to those provided by Gorochov (2001 a). For now, the Neotropical genera are the ones that should be included in Lutosini, sharing a morphology in terms of the organization of the last abdominal tergites and the hooks. These morphological characters are far different from the anatomy of the species of Old-World genera, such as Libanasa Walker, 1869 and Papuaistus Griffini, 1911. Indeed, for us, these Old-World genera should be relocated to other suprageneric taxa in future contributions. In this way, Lutosinae / ini would have a Neotropical distribution, and be morphologically close to Anostostomatinae / ini, in contrast to the other tribes of the family.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).

03B487AE2B3CFFC3F7C3FC76FD0EFF37.taxon	description	In recent years, contributions to the different genera of American Lutosini have been made, and there is a good definition of the genera and species, with detailed data on the morphology of the terminalia and, in most cases, the internal genitalia: Apotetamenus (Cadena-Castañeda & Cortés-Torres 2013), Hydrolutos (contributions by Derka & Fedor), Lutosa Walker, 1869 (Morselli 2006, 2010, Heleodoro & Mendes 2016), Neolutosa (Gorochov 2001 a), Rhumosa (Hugel & Desutter-Grandcolas 2018), and Tintiyakus (Mendes et al. 2020, Mendes & Heleodoro, 2021). Licodia is an exception, it is poorly studied, and the last contribution to the genus was made by Rehn (1930). Details of the male terminalia and internal genitalia are unknown, and additional species may need to be described from its Greater Antilles range. In the particular case of Lutosa, more emphasis was given in this contribution, to better understand the morphology and definition of Lutosini. Its distribution was restricted to the Atlantic Forest, between Brazil, Argentina and Paraguay, but here firstly recorded to Amazon. As a result of this contribution, Lutos a remains with ten species: L. anomala, L. brasiliensis, L. cubaensis, L. goeldiana, L. imitata, L. marginalis, L. normalis, L. paranensis L. quaresmai n. sp. and L. morsellii n. sp. It is evident that many more species must be described from the Atlantic Forest, so it is important that Morselli (2010) publish his thesis and formally made available the diversity of species in the genus. We have additional species to describe, but on this occasion, we abstain from publishing or describe them, so as not to affect the magnificent work of Morselli. Here we only describe L. quaresmai n. sp. and L. morsellii n. sp., having the certainty that it does not coincide in any taxon of the author’s thesis. Outside of the Atlantic Forest, it is possible the existence of additional undescribed species. Currently representatives of these possible new species are only known from females recorded for French Guiana (Karny 1935) or Colombian Amazon, with females from Colombian entomological collections. We prefer to wait to find males of the Amazonian or Guyanese representatives, to certify that they are Lutosa or if they are a morphologically similar genus such as Neolutosa or Rhumosa, that their females are identical to those of Lutosa.	en	Cadena-Castañeda, Oscar J., García, Alexander García, Nos, Maria Del Pilar Castella-, Sarmiento, Juan Pablo Prias, Tavares, Gustavo Costa (2022): Studies on chevron crickets: Contribution to the knowledge of Lutosinae / ini taxa (Orthoptera: Anostostomatidae).
