0384CB1BA462C94D96892E63FB62FC88.taxon	discussion	Remarks. Syneches applanatus is similar to S. repletus due to the flat ocellar triangle, pterostigma brown and round, ending near apex of cell r 1 and hind femur strongly swollen in males. However, S. applanatus differs from S. repletus by the fore and mid femora mostly brown to reddish brown, hind tibia with a brown ring at mid-length and hind femur bearing 1 AV row of spiniform bristles inserted on short tubercles. In S. repletus, the fore and mid femora are yellow, hind tibia is yellow lacking dark ring, but with the apical half to apical third brown and tubercles of the hind femur much longer than those of S. applanatus. The original description states that the prescutellar disc bears reddish brown pruinescence (Menezes & Ale-Rocha 2016), but examination of the holotype revealed that the prescutellar disc is covered with gray pruinescence, contrasting with the rest of the scutum.	en	Soares, Matheus M.

0384CB1BA467C94996892B7BFB9EF85A.taxon	discussion	Remarks. Syneches bilobatus is similar to S. pyramidatus given the wing hyaline, pterostigma inconspicuous, scutum pyramidal-shaped, broader than mesopleuron and covered with reddish brown pruinescence. However, the species differs from S. pyramidatus by the brown to dark brown fore and mid tibiae with yellow base and apex (yellow in S. pyramidatus), hind tarsomere 1 brown with base and apex yellow (yellow in S. pyramidatus) and second section of M 1 slightly shorter than crossvein r-m (second section of M 1 longer than r-m in S. pyramidatus). The original description states that there is yellowish-gray pruinescence forming dorsocentral and supra-alar stripes (Menezes & Ale-Rocha 2016), but we could not distinguish the yellowish-gray stripe in the holotype and paratypes, and now consider that the whole scutum is covered with a reddish brown pruinescence.	en	Soares, Matheus M.

0384CB1BA464C94696892853FBFCFEC8.taxon	discussion	Remarks. Syneches catarinae, S. curvipes and S. walkeri are closely related species and possibly form a monophyletic group by sharing the large size and strong aspect, wide prosternum, dorsocentral stripe with gray pruinescence, scutellum with more than 16 bristles and hind femur strongly swollen with 1 AV series of spiniform bristles inserted on short tubercles, besides the apical margin of the hypandrium with a deep mid-width concavity, forming two long lobes. However, S. catarinae may be differentiated from S. walkeri by the long and oval pterostigma, fading off apically, hind femur yellow with a wide ring at mid-length and apex brown and hind tibia brown on apical third. In S. walkeri, the pterostigma is short, quadrangular, the hind femur has a pale brown ring on apical third and the hind tibia is yellow with a brown ring at mid-length. Also, S. catarinae has the antennae brown with postpedicel varying from yellow to brown, palpus, proboscis and fore tibia yellow, apex of postgonite truncate, epandrial lamellae wide, narrowing abruptly towards apex (boot-like shape), but differing from S. curvipes, which has antennae, palpus and fore tibia brown to dark brown, apex of postgonite rounded and epandrial lamellae wide, slightly narrower on apical half. Moreover, S. atratus and S. rafaeli seem to be related to these species. Syneches atratus shares the strong aspect, the hind femur strongly swollen with 1 AV row of spiniform setae inserted on short tubercles and the apical margin of the hypandrium has a deep mid-width concavity, forming two long lobes (Soares & Ale-Rocha 2018, fig. 1), but it has a narrow prosternum and the scutum is homogenously covered with reddish brown pruinescence. Syneches rafaeli shares the wide prosternum and the dorsocentral stripe with gray pruinescence, but it has a medium-size length, without strong aspect and the hind femur weakly swollen.	en	Soares, Matheus M.

0384CB1BA45AC97696892A1CFE84FF2C.taxon	discussion	Remarks. This unusual species is probably the most autapomorphic in the genus, by the following set of characters: postpedicel very long, about 3 x longer than preceding segments combined (the longest for the genus up-to-date), prosternum fused to proepisternum, abdomen weakly sclerotized and epandrial lamella with 1 long dorsoapical projection, about half-length of lamella (Ale-Rocha & Vieira 2008, fig. 17). The prosternum is fused to the proepisternum forming a precoxal bridge that does not seem to be homologous to that of the other Brazilian species of Syneches: S. catarinae, S. curvipes, S. rafaeli and S. walkeri because in these latter species, the prosternum has a wide connection with the proepisternum (Fig. 2 C), while in S. longiflagellatus these sclerites are connected by a narrow region.	en	Soares, Matheus M.

0384CB1BA458C97096892804FA99FC1C.taxon	discussion	Remarks. Syneches luteus is a medium size species with 18 marginal scutellar bristles. This great number of scutellar bristles and the second section of M 1 twice longer than crossvein r-m is shared with S. atratus, S. catarinae, S. curvipes and S. walkeri, which are medium to large size species. However, Syneches luteus does not have the wide prosternum nor colored pterostigma. Syneches luteus can be differentiated from the above mentioned species by the antenna yellow with dark brown postpedicel, legs mostly yellow and wing hyaline with pterostigma inconspicuous. The extensive damage on the scutum of the holotype did not allow us to describe the acrostichal and dorsocentral series and we were not able to associate this female with any male, or even include additional specimens to this species. Wiedemann (1830) described the species based upon the specimens collected by Mr. Wilhelm Freyreiss, a German naturalist who made expeditions between 1812 – 1814 through the current Brazilian administrative States of Rio de Janeiro, Espírito Santo, Bahia and Minas Gerais (Papavero 1973). Hence, despite not being able to provide a more precise distribution of the species other than that provided above, it is reasonable to suppose that S. luteus occurs in the Atlantic Forest biome and it may occur from the northern Southeast to southern Northeast Brazil.	en	Soares, Matheus M.

0384CB1BA45CC97396892FD2FBADFC38.taxon	discussion	Remarks. Syneches manaos is remarkably similar to S. repletus, due to the flat ocellar triangle, mid tibia with long bristles, as long as tibia and hind femur strongly swollen in males bearing 1 AV series of spiniform bristles inserted on prominent tubercles. However, in S. manaos the hind femur is brown and R 2 + 3 is strongly angulated near the apex, while in S. repletus the hind femur has the basal third to basal half yellow and R 2 + 3 is only slightly angulated near apex. According to Smith (1962), S. manaos is closely related to S. curvineura Melander and S. longiventris Melander, but these two species have the ocellar triangle protuberant. Nevertheless, we have examined the syntypes of S. barypterus Melander and S. planiceps Melander as well as the original descriptions of Melander (1928) and there is no doubt that these species are closely related to S. manaos and S. repletus. Syneches applanatus seems to be related to that group, but lacks the prominent tubercles on the hind femur.	en	Soares, Matheus M. M., Freitas-Silva, Rafael A.

0384CB1BA443C96E96892C07FE6FF855.taxon	discussion	Remarks. Syneches nordestino sp. nov. is similar to S. tomentosus due to the fore tibia darker, femora slender and yellow. However, in S. nordestino sp. nov., the postpedicel is yellow to pale yellow, the pterostigma lacks a marginal proximal invagination and the hypandrium has the distal margin trapezoidal, bearing a wide median subtriangular preapical protuberance. In S. tomentosus, the postpedicel is brown to dark brown, the pterostigma bears a marginal proximal invagination and the distal margin of hypandrium has a shallow, mid-width concavity, forming two short lobes.	en	Soares, Matheus M.

0384CB1BA449C96796892E2BFD66FB7F.taxon	discussion	Remarks. Syneches ruficollis was described based on a single female from Brazil. Smith (1962) reported that the holotype could not be found in the Natural History Museum (NHMUK) and that it was possibly lost. According to the original description, the species has the following set of relevant characters: antenna yellow, thorax brownish yellow, legs yellow covered with concolorous bristles, all tarsus or some of them dark brown, abdomen black and wing hyaline with pterostigma spindle-shaped (= oval). Some of these characters are common in many Brazilian species: S. fasciatus sp. nov. and S. flaviscutellatus sp. nov. (antenna and legs mostly yellow, but both species have a distinct color pattern on the thorax and the wing mostly brown), S. sinclairi sp. nov. (but the female has an inconspicuous pterostigma and all the tarsi yellow) and S. tenebricus (but all tarsi are yellow and the wing is brownish). Thus, without analyzing the holotype, it is impossible to correctly associate S. ruficollis with any Brazilian species, hence we treat this name as a nomen dubium.	en	Soares, Matheus M.

0384CB1BA433C91F96892D03FDFBFDE8.taxon	discussion	Remarks. Syneches striatus is one of the most morphologically variable Brazilian species of Syneches and it is apparently composed by two groups of species. One group comprises specimens from North Brazil (administrative states of Amazonas and Amapá), with a long postpedicel, almost twice longer than preceding segments, which color varies from pale yellow (Amazonas) to dark brown with pale yellow apex (Amapá), and the hind femur is only slightly swollen. The other group is composed by specimens from other parts of Brazil, with specimens from the administrative states of Maranhão (Northeast Brazil), Espírito Santo (Southeast Brazil), Mato Grosso (Center West Brazil) and Paraná (South Brazil), which have the postpedicel wholly yellow, short, subequally long to the preceding segments combined and the hind femur strongly swollen. All specimens of S. striatus share the proepisternum long, almost reaching the prosternum to form a precoxal bridge. Wings, as well as male and female terminalia, show no significant variation. Therefore, we suspect that this species may actually represent a species complex, but presently we prefer to maintain all under the same name until additional studies, particularly molecular based ones, can give us some light into this issue.	en	Soares, Matheus M.

The species is recorded only from two very contrasting landscapes in the Amazon biome, namely from Manaus (central Amazon, State of Amazonas) and Pacaraima (northern Amazon, state of Roraima). However, it is interesting to note that both localities are composed of essentially different vegetation types; while the landscape nearby Manaus is predominantly of close canopy rainforest, Pacaraima shows a predominantly open savanna-like landscape.	en	Soares, Matheus M.

Syneches tomentosus is similar to S. nordestino sp. nov. by the medium size, thorax dark brown covered with reddish brown pruinescence and legs mostly yellow. However, S. tomentosus can be differentiated by the oval pterostigma, about 3.5 x longer than wide, with a marginal proximal invagination and postpedicel mostly dark brown (pterostigma absent and postpedicel pale yellow in S. nordestino sp. nov.). Additionally, the characters of the male terminalia contribute to distinguish these species. See also “ Remarks ” under S. nordestino sp. nov.	en	Soares, Matheus M. M., Freitas-Silva, Rafael A.

Syneches walkeri displays remarkable morphological variation, with some specimens predominantly yellow, while others are predominantly dark brown to black. However, the pattern of the wing and the morphology of the male terminalia is similar in all specimens. One studied specimen was collected with a light trap set on the top of a tower (45 m high), located in a primary forest in northern Manaus, indicating that the species may also inhabit the canopy of the forest.	en	Soares, Matheus M.
