03AE87FEFFB5FFD7821EF8CE5A82FA25.taxon	diagnosis	Diagnosis Head broader than high; scapal basin concave, striate, or punctate; TFC various, usually single and medially raised, sometimes double, down curved along eye margin, or with branches upward extended to ocellar area; MS usually about 1 MOD; pronotum with distinct and complete sublateral carina, sometimes incomplete or weak, faint in the inops species group; mesopleuron with broad episternal and scrobal sulcus; metasoma with geminate punctures; T 2 usually with median carina; T 3 with three or five teeth; lateral teeth in some species can be merely angle-shaped; S 2 with black spots usually fused medially, rarely separated by a narrow line, or largely separated in the inops group, however, never connected to anterior or lateral margins. Members of this genus are usually completely blue or green in colour, but a few Indian and African species have red markings, in particular on the metasoma; small males can often be blackish dorsally. The genus Trichrysis is currently subdivided into three heterogeneous species groups: the cyanea, inops and lusca groups (Rosa et al. 2016). Indian members are subdivided in the following groups: • lusca group: Trichrysis bengalensis (Mocsáry, 1889) T. imperiosa (Smith, 1874), T. lusca (Fabricius, 1804) • cyanea group: Trichrysis excisifrons (Mocsáry, 1912), T. lanka (Bingham, 1903), T. poseidonia sp. nov., T. tonkinensis (Mocsáry, 1914), T. triacantha (Mocsáry, 1889) • inops group: Trichrysis inops (Gribodo, 1884), T. scioensis (Gribodo, 1879)	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFB5FFD7821EF8CE5A82FA25.taxon	biology_ecology	Hosts Hosts are cavity-nesting crabronid and pompilid wasps (Pärn et al. 2014; Paukkunen et al. 2015; Pauli et al. 2019). Additionally, cavity-nesting solitary bee species have been reported in the old literature as hosts (e. g., Trautmann 1927), but these records should be considered unreliable due to the very different biology of bees compared to crabronid and pompilid hosts.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFB5FFD7821EF8CE5A82FA25.taxon	diagnosis	Differential diagnosis In the Old World, some members of Trichrysis can easily be confused with members of the genus Chrysidea. Linsenmaier (1987) synonymised Chrysidea with Trichrysis (as a subgenus of Chrysis), but the genus Chrysidea was later considered as valid and separate by Bohart (1988) and Kimsey & Bohart (1991). The recent phylogeny by Pauli et al. (2019) shows a close affinity between these two genera, which are well identified in a subordinated clade. However, considering the position of these two genera within the Chrysis lineage, the authors suggested combining both genera with Chrysis Linnaeus, 1761. We support the point of view of Pauli et al. (2019); however, waiting for a revision of the Chrysidini classification, we still consider the two genera separately. A combination of morphological characteristics allows the separation of Trichrysis and Chrysidea (Table 1): sublateral carina (present in Trichrysis vs faint or rarely present in Chrysidea and in some species of the inops group); black spots on the second sternum (medially fused or nearly so in Trichrysis vs distinctly separated by 1 – 2 × MOD in Chrysidea and the inops group); number of teeth on the apical margin of the third tergum (three or five in Trichrysis, sometimes lateral ones barely visible like angles vs two lateral teeth, medially straight, weakly undulate, or rarely with a median tooth in Chrysidea); transverse frontal carina (variable in Trichrysis, anyway not topping the scapal basin, vs topping the scapal basin in Chrysidea); medial cell [= discoidal cell in Kimsey & Bohart 1991] (complete in Trichrysis, Chrysidea falsa and C. mendicalis vs incomplete in the other members of Chrysidea, with its outer veins either not or only partly sclerotised); genital capsule (gonocoxa shortened with distinct, elongate gonostylus vs gonocoxa fully developed without distinct gonostylus); body colours (green and blue in both genera, yet some species of Trichrysis have red, golden or bronze spots, stripes, or highlights which are not recorded in Chrysidea). Rosa et al. (2021 a) recently published a checklist of Indian cuckoo wasps, with a key for the identification of known and expected genera for the country.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFB3FFD581A4FA305D0DFD03.taxon	discussion	Remarks The holotype of Chrysis bengalensis Mocsáry, 1889 (Fig. 1) is different from the examined specimens of Trichrysis lusca (Fig. 3), as described by Mocsáry (1889) and Bingham (1903). In addition to the uniform dark blue colouration (vs more extensively green to light blue in T. lusca) and the dark brown wings (vs light fusco-hyaline in T. lusca), it is coarsely punctured with large and deeper punctures, compared to T. lusca; the TFC is close to the upper margin of the scapal basin and without the vertical frontal carina that originated from the mid TFC and bisecting the upper frons, as in T. lusca (compare Rosa et al. 2016: fig. 40); the two lateral, upward branches of the TFC are raised (vs irregular); the pit row has large and deep pits (vs small); the apical margin bears three pointed teeth with an angle between the median and the lateral tooth instead of five distinct, short teeth; intervals between teeth are wider than in T. lusca. Based on the type examination, and the characters listed above, we consider T. bengalensis as a valid species, and we here resurrect it from the previous synonymy with Praestochrysis lusca proposed by Kimsey & Bohart (1991). The placement of the lusca species group in the genus Trichrysis rather than in the genus Praestochrysis was already discussed by Linsenmaier (1997) and Rosa et al. (2016). Other specimens examined from the Oriental region show differences from the type of Trichrysis lusca (Fig. 3) and are very likely members of a species complex, which is worthy of further investigation.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFB0FFDA8209FD0D5D62F921.taxon	diagnosis	Differential diagnosis The specimens recorded are very similar to Trichrysis natalica (Mocsáry, 1913). This taxon, together with all the other species included in the inops group, was synonymised with T. inops by Kimsey & Bohart (1991) in the genus Praestochrysis Linsenmaier, 1959. Linsenmaier (1997) and Rosa et al. (2016) have already discussed the affinities of the members of this species group with Trichrysis rather than Praestochrysis. After examination of almost all the types included in this species group and copious material, we consider the inops species group to be a rich group of species, mostly distributed in the Afrotropical region. Together with other experienced colleagues (e. g., Marek Halada (Czech Republic) and Maurizio Pavesi (Italy )) we think that several taxa placed in synonymy with inops by Kimsey & Bohart (1991) are valid species (pers. comm.). However, the revalidation of these taxa will be performed in a future article focused on African Trichrysis. In the present article, we maintain the classification proposed by Kimsey & Bohart (1991) and identify this Indian species as T. inops. Another two species, T. scioensis (Gribodo, 1879) and T. baratzensis Strumia, 2009, may be included in this group, although they show some differences having only three teeth and two distinct angulate convexities in the intervals between the median and lateral teeth, instead of five pointed teeth, and the shape of the S 2 black spots clearly larger and rounded. Trichrysis inops is separated from the other pentadentate Indian species, T. imperiosa and T. lusca, by faint TFC and lateral pronotal carina, and by small dimensions (5.0 to 6.0 mm instead of 6.5 to 10 mm) and slender body (vs stocky). It is separated from other Indian Trichrysis by faint TFC (vs TFC raised), small and separate black spots on S 2 (vs larger and medially united); five distinct apical teeth on the margin of T 3 (vs three distinct teeth or three teeth with two angulate convexities in the intervals between medium and lateral teeth). The occurrence of T. inops in India may be the result of an accidental introduction through commerce, because all known records are so far limited to Sub-Saharan Africa. The species could have adapted to the Indian climate and to a native host, but more research is needed looking for its hosts and nests.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFBEFFD98212F97A5AECFAA8.taxon	discussion	Remarks Chrysis spectrum (Fig. 3) was described five years after Bingham’s description of Chrysis lanka. In the paper, Wickwar (1908) listed four specimens, but only two are still preserved in the collection at NHMUK, both in rather poor condition, mainly due to mould. Both are specimens of Trichrysis lanka. Bohart in Kimsey & Bohart (1991) designated the lectotype of T. spectrum and synonymised it with T. lanka. Unfortunately, no specimen examined at NHMUK bears a lectotype label, and no information has been provided by Kimsey & Bohart (1991) to recognise the selected lectotype in the collection, thus making the designation invalid. To prevent further misunderstandings, we (BW) here designate the lectotype based on the female (Fig. 3) bearing the labels: Colombo, Ceylon, O. S. W.; Ceylon O. S. Wickwar 1912 - 189; Chrysis spectrum; Type O. S. Wickwar; B. M. Type Hym. 13.52 [13 G Chrysididae, drawer 71]. The type of Chrysis lanka was not found at NHMUK (Kimsey & Bohart 1991, pers. comm.) and could possibly be deposited in the Mocsáry collection (HNHM), who bought part of the Bingham collection (Rosa et al. 2017).	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

(2021 a) and possibly referred to another species later described in this genus. However, the discovery of T. inops in India and the occurrence of other species or even genera in India and Africa in recent years, i. e. the genus Odontochrydium Brauns, 1928 (Rosa 2018), the species C. principalis Smith (Rosa et al. 2015), species of the mandibularis group (Rosa & Halada 2021), T. inops (this paper), suggest a wider correlation between the two faunas, not yet carefully studied. For this reason, in the present article we list and key this African species.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFA7FFC28269FEDB5AB0FD5C.taxon	discussion	Remarks Rosa et al. (2016) considered Trichrysis triacantha as a possible synonym of T. vestigator (Smith, 1858) based on illustrations of the apical margin of T 3 provided by Bohart (1988: fig. 6) and Kimsey & Bohart (1991: fig. 150 c). Thanks to the kind help of James Hogan (OUMNH), we examined pictures of the type of T. vestigator and can state that the two taxa are closely related. Actually, the intervals between the median tooth and the lateral teeth of the type specimen are straight and not convex, as shown in the illustrations of Bohart (1988) and Kimsey & Bohart (1991). Taking into account the high variability of this species, as recorded by Rosa et al. (2016), based on specimens collected in the same locality in China, we agree that the two species could be conspecific; however, examination of more material is needed prior to proceeding with this synonymy.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).

03AE87FEFFA4FFC681AAF9F559E3FC3C.taxon	discussion	Remarks Chrysidea mendicalis (Cameron) has traditionally been included in the genus (or subgenus) Trichrysis. The specimen of Trichrysis mendicalis illustrated in the Indian species checklist (Rosa et al. 2021 a) is a misidentified one from the Mocsáry collection (HNHM). In fact, Mocsáry acquired the chrysidid collection of C. T. Bingham (Mocsáry 1911, 1912; Rosa et al. 2017), including types of species described by Bingham and Nurse. The illustrated specimen was originally from the Bingham collection. Since Bingham studied Cameron’s collection, this identification has been considered reliable. A recent examination of the holotype of Trichrysis mendicalis (Fig. 8) deposited at OUMNH revealed that this is a species of Chrysidea, closely related to Chrysidea falsa in particular. The main difference between these two species is found in the metasomal punctation (smaller and denser dorsally in C. falsa, Fig. 9 C) and in the shape of the apical margin of the T 3; in Chrysidea mendicalis the post-pit area is more extended and the intervals between the median and the lateral tooth are more concave to angulate (Fig. 9 B). The Sri Lankan specimen illustrated in Rosa et al. (2021 a) may be temporarily identified as Trichrysis triacantha.	en	Bijoy, Paolo Rosa Pokkattu Gopi Aswathi Bogdan Wiśniowski Chenthamarakshan (2022): Preliminary revision of the Indian cuckoo wasp genera Trichrysis Lichtenstein, 1876 and Chrysidea Bischoff, 1910, with description of a new species (Hymenoptera, Chrysididae).
