I: 0.8–1.0; II: 1.4–1.6; III: 1.0–1.3; IV: 3.5–4.1; V: 4.2–4.5. Diagnosis. Anterolateral margin of pronotum without black stripe. Anterolateral margin not punctured dorsally. Cicatrices of pronotum with light brown punctures delimiting anterior sulci (Fig. 19A). Scutellum with anterior margin yellow (Fig. 19A). Body ventrally with narrow brown stripes (Fig. 19B). Male genitalia (Fig. 7A–D). Pygophore remarkably excavated laterally (Fig. 7C–D), leaving the parameres visible in lateral view. Dorsal rim rugose and projected posteriorly, surpassing level of posterolateral angles (Fig. 7A). Superior process of genital cup triangular, short, tapering to the base, and close to dorsal rim; visible in dorsal view (Fig. 7A–C). Paramere spatulate; anterior lobe developed and rounded; posterior lobe well-developed and subtriangular; outer margin black; stalk with inner medial carina low, evanescent and curved toward anterior lobe (Fig. 7B–C). Proctiger with dorsolateral tufts of setae clearly separated by medial bridge; posterior face pentagonal with both lateral margins swollen and somewhat ventrally projected (Fig. 7B–C). Ventral rim remarkably projected caudally; medial excavation shallow; expansions slightly tumid, acuminated, and narrow; apices densely setose, surpassing level of posterolateral angles in ventral view (Fig. 7D).

Valvifers 8 subtrapezoidal, posterior margin sinuous; inner angles reaching basal third of valvifers 9, not touching each other; inner margins forming a long and narrow drop-like excavation. Valvulae 9 exposed. Comments. The H. excavatus like H. omegoides, (Fig. 10C–D) and H. boerneri (Nunes et al. 2020, Fig. 2C) has the lateroventral side of the pygophore remarkably excavated, leaving paramere completely exposed laterally (Fig. 7C–D). This condition also gives the impression that ventral rim of the pygophore is strikingly projected caudally, completely different from all other species of the genus. The species H. excavatus and H. omegoides show the lateral margins of the posterior face of the proctiger ventrally projected (Figs. 7B, 10B) (just surpassing the margin in H. excavatus and strongly developed in H. omegoides). Females from H. excavatus and H. boerneri are very similar (Fig. 7E; Nunes et al. 2020, Fig. 2D). The main difference between these species is the median excavation of valvifers 8 in H. excavatus (Fig. 7E) that is narrower with apices of inner angles closer to each other than in H. boerneri. Etymology. The name refers to the strongly excavated lateral surface of the pygophore. Distribution (Fig. 21B). BRAZIL: Rondônia, Mato Grosso.

Female genitalia (Fig. 11E). Valvifers 8 subtrapezoidal with posterior margin almost straight; inner angle reaching half of valvifers 9; inner margins divergent in distal half and dark. Valvulae 9 exposed. Valvifers 9 strongly setose. Comments. This species is related to H. trabeculus and H. similis by the paramere golf club like; posterior face of proctiger pentagonal; dorsal rim medially with a small convex expansion, and expansions of ventral rim with setae long and dense on apex (Figs. 11A–D, 14A–D; Nunes et al. 2020, Fig. 8A–C). However, in H. pentagonalis the posterior process of the paramere is curved dorsolaterally (straight in H. similis and H. trabeculus). The superior process of genital cup is curved with a distal digitiform process on ventral margin (straight in H. trabeculus and curved but without ventral process in H. similis). The valvifers 8 of these species are very similar, especially the mesial distal excavation V-shaped, but the outer angles of distal margin are more angulated in H. pentagonalis than in the other species. Etymology. Name refers to the pentagonal form of the posterior face of the proctiger. Distribution (Fig. 21B). BRAZIL: Maranhão, Pará.

Comments: St��l (1872) described Edessa sahlbergii from a female collected in Rio de Janeiro, Brazil. Notes from Pieter van Doesburg regarding this species considered the specimen in Stockholm to be the holotype of the species and also did not mention another specimen in any collection with material studied by St��l. Therefore, the female is considered the holotype of the species. This species was included in step ���o��� of the key (species group ��� Edessa ���), among species with wide humeral angles, depressed, rounded anteriorly, and with a ventral surface distinctly punctate (St��l 1872). Edessa sahlbergii and E. graziae sp. nov. are the only variegated species of the group; both also share the metasternal process with punctures associated with setae and dark spots. But an obvious difference between them are the almost flat and punctured humeral angles of E. sahlbergii. Other differences between both species are subtle, including posterior lobe of the paramere; the shape of superior process of the genital cup; and humeral angle projection. The male of the Edessa sahlbergii is described for the first time.

Comments: Bergroth (1891) described Edessa impura from Minas Gerais, Brazil. The original description mentioned only one male, in which the species was described. Later, Dr. Pieter van Doesburg made notes about this male, referring to it as the holotype of the species. My personal (J.A.M., Fernandes) search in the Fallou collection located only one specimen of E. impura ���the type specimen mentioned by Dr. van Doesburg (J.A.M. Fernandes, pers. Observ.), therefore we consider this specimen the holotype of the species. We are considering Edessa argali Breddin, 1903, described from two males collected in S��o Paulo, Brazil, a junior synonym of E. impura based on morphological similarities of the genitalia and the color of the humeral angle. Edessa impura is the only species included in this work that has humeral angles with yellow apices pale see comments for E. ovina. The female is described here for the first time.

Comments: Currently, Edessa is formed by three subgenera: Edessa, Aceratodes, and Dorypleura. The target group of this study is part of the nominal subgenus diagnosed by humeral angle conical; apex globose or depressed, posteriorly curved, impunctate, shiny and black in most of the species, according to St��l (1872). Recently, Val��ria Silva (the second author) revised most of the species of the subgenus Edessa (in preparation) and the cladistic analysis indicates this subgenus as a monophyletic taxon. The subgenus Edessa assembles more than 150 species, most of them still undescribed. The E. ovina species group can be recognized by the apex of the metathoracic wings narrowed, and the ventral surface of the pygophore with a central tumid area projected posteriorly. The E. ovina species group is clearly divisible into two morphological subgroups of species based in coloration; punctures of the dorsal and ventral surface; surface of the metasternal process; and shape of parameres. The first subgroup gathers E. ovina and E. impura, both having dorsal surface uniformly green; metasternal process flat; and the central tumid area of the pygophore poorly projected posteriorly. While the species E. sahlbergii and E. graziae sp. nov. have the dorsal surface variegated (green and brown, sometimes also yellow); metasternal process raised anteriorly, in lateral view, and punctate; and the central tumid area of the pygophore strongly projected posteriorly. These species are found only in South America and three out of four species were registered mainly at the very endangered Atlantic Forest biome. Very little is known about these species concerning biology or ecology. Only two records about the host plant are known and both are on Bignoniaceae of the tribe Bignonieae. Edessa ovina was collected on Dolichandra unguis-cati (L.) L.G.Lohman and E. graziae sp. nov. on Pyrostegia venusta (Ker Gawl.) Miers. Edessa graziae was observed and collected by the first author several times over a few years in his garden in Porto Alegre, Brazil. The nymphs were observed on slender branches and adults on woody parts of the branches, both never observed feeding on fruits or seeds. Specimens stood still when gently disturbed, walking away when effectively disturbed, rarely flying away, preferring to fall freely (thanatosis) on the ground, disappearing into the leaf litter. They were active only during the summer (January���March), disappearing during the rest of the year. Part of the specimens were captured in autumn (October���December) in diapause under roof tiles and at the base of hibiscus plants, in both cases in the accumulated leaf litter.

This species is more closely related to Edessa brunneofasciata sp. n. because of similar male genitalic characteristics such as: parameres large, forming two projections: one dorsally directed and the other curved laterally which fits between the tumescence of the inner surface of the lateral angles and the expansions of the ventral rim (Figs. 3B; 4B); the ventral rim with a medial shallow excavation delimited by small rounded expansions (Figs. 3C; 4C). This species can be differentiated from E. brunneofasciata sp. n. by its distinct mossy green and orange coloration, the length of the parameres that partially ���embrace��� the tumid adjacent posterolateral angle, the proctiger extremely excavated laterally, and by the small posterior face of the proctiger (Figs. 3B; 4B).

Coria each with an orange stripe on costal margin, which continues the orange stripe of pronotum (Fig. 5A); punctures concolorous, except on brown spot where punctures are black. Posterolateral angles of pygophore clearly below the level of dorsal rim in lateral view and fused to ventral rim, forming a deep and concave structure (Fig. 1A,B). Paramere formed by a single projection straight and dorsally directed (Fig. 1B). Posterior margins of gonocoxites 8 acute and clearly surpassing gonocoxites 9 (Fig. 1D). Description. Head. Mandibular plates with apical margins dark. Thorax. Apical margins of humeral angles brownish. Scutellum with apex impunctate. Veins of coria concolorous with surrounding area (Fig. 5A). Membranes of hemelytra light brown (Fig. 5A). Ventral surface with dark punctures concentrated on pro- and metapleura (Fig. 5B). Abdomen. Posterior third of seventh connexival segments black. Male (Fig. 1 A���C). Dorsal rim of pygophore sinuous, darker than dorsal surface, ending in a suture close to each posterolateral angle (Fig. 1A); with a pair of submedian brown concretions. Posterolateral angles posteriorly projected and rounded, slightly tumid with a dark spot below tumescence (Fig. 1A). Superior process of the genital cup kidney-like, black, short, narrow, with a medial depression; oblique to dorsal rim (Fig. 1B). Parameres tongue-like, short, yellow to green on base, remaining parts black. Proctiger posterolaterally excavated, excavations deep, dorsally delimited by raised crest; posterior face subtriangular with medial short vertical carina, ventral corners black (Fig. 1B). Ventral rim (vr) with medial deep excavation delimited by rounded concave expansions, barely tumid, level with posterolateral angles in ventral view (Fig. 1C). Ventral surface rugulose medially, sparsely Punctured. Female (Fig. 1D). Gonocoxites 8 slightly convex; strongly projected posteriorly, reaching distal halves of laterotergites 9, outer lateral margins straight; mesial border projected forming a medial tooth. Gonocoxites 9 strongly inclined laterally. Laterotergites 9 concave basally; apices clearly surpassing sclerite uniting laterotergites 8. Comments. This species is more closely related to E. translucida sp. n. than to the other species of the group because of the lack of pigment in the medial region of each corium (Fig. 5A,C), and the ventral rim of the pygophore with expansions distinctly projected and level with the posterolateral angles (Figs. 1C; 2C). However, E. stalii can be differentiated by its parameres each with a single projection, the superior process of the genital cup kidney-like, and the gonocoxites 8 distinctly projected posteriorly (Fig.1B,D); whereas in E. translucida sp. n., the parameres are divided into two lobes, the superior process of the genital cup is rounded, and the gonocoxites 8 are only slightly projected posteriorly (Fig. 2B,D).

Bergroth (1891) related Edessa subrastrata to E. triangularis and E. affinis, but the morphological characteristics pointed by the author are, actually, shared by many species. Hypoxys triangularis is closer to H. subrastratus but is larger and has a smoky stripe on pronotum (Fig. 19E and 19I). Edessa affinis is smaller, its metasternal process has apices of the arms rounded and genitalia from both sexes are quite different from H. subrastratus. The male is described here for the first time. Distribution (Fig. 22).

Anterolateral margin of pronotum with complete solid black stripe. Cicatrices with brown punctures delimiting anterior sulci (Fig. 19C). Anterolateral margin with some brown punctures. Male (Fig. 8 A–C). Pygophore with dorsal rim sinuous, shallowly excavated (Fig. 8A). Superior process of genital cup laminar with outer corner protruding; adjacent to dorsal rim (Fig 8B). Paramere elongated, club-like, strongly bent laterally; inner margin with conspicuous carina ending at rounded apex of bent part (Fig. 8B); anterior face of bent part strongly concave. Proctiger with large tufts of setae separated by small carina; posterior face pentagonal (Fig. 8B) and transversly concave, base of the setae on lateral margin projected (but not visible due the setae). Ventral rim central excavation widely and shallowly excavated; expansions well-developed. tumid and rounded, surpassing level of posterolateral angles in ventral view, setose (Fig. 8C). Female (Fig. 8D). Gonocoxites 8 slightly convex, posterior margin angulate; inner angle covering almost half of gonocoxites 9; sutural border slightly divergent in distal half. Gonapophyses 8 barely exposed. Comments. Breddin (1907) said that E. trabecula is similar to E. quadridens mainly because of the ratio between eye width and pronotum length; however, this is a not reliable character. A variation among specimens was observed and the posterior margin of gonocoxites 8 can be less slanting than shown (Fig. 8D). Females of H. trabeculus have a characteristic gonocoxite 8 with its angulate posterior margin and sutural border divergent on distal half (Fig. 8D). The other female with subrectangular gonocoxites 8 is H. claricolor, but the inner angle of gonocoxite 8 in H. claricolor is rounded and sutural border excavated in “U” (Fig. 3D), also laterotergites 9 have distal angle rounded (acute in H. trabeculus). Males of H. trabeculus (Fig. 8B) have paramere club-like and projected laterally like in H. claricolor (Fig. 3B). But, in H. trabeculus inner carina is higher than in H. claricolor and reaches the apex of the paramere (Fig. 8B); superior process of genital cup is laminar and straight; expansions of ventral rim are tumid, and posterior face of the proctiger is wider than long (Fig. 8B). In H. claricolor the inner carina is low and ends up in the middle of the paramere; superior process is narrow, curved with a median projection; expansions of ventral rim are flat, and posterior face of the proctiger is longer than wide (Fig. 3B).

Pronotum with small, elongate, lateral black spots including posterolateral angles. Anterolateral margin of pronotum without solid black stripe and not punctured. Posterolateral angles developed, as long as interocular distance. Anterior margin of scutellum yellow (Fig. 20E). Dorsal surface of abdomen brown. Connexivum green without spots, except distal margin of segment VII, dorsally urotergite 8 with inner black stripes continuing in free part of laterotergites 8 (Fig. 20E). Ventrally apex of pseudosutures without rounded dark spots (Fig. 20F). Male (Fig. 15 A–C). Pygophore with dorsal rim barely excavated; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim (Fig. 15A,B). Paramere with anterior lobe strongly developed, almost reaching base of proctiger; posterior lobe strongly developed and acuminated (Fig. 15B). Proctiger with tufts of short setae widely separated, but not as much as in H. oxyacanthus. Ventral rim with expansions well developed, barely tumid, and rounded (Fig. 15C). Female (Fig. 15D). Gonocoxites 8 inner angle covering base of gonocoxites 9. Laterotergites 9 wide, lightly surpassing sclerite uniting laterotergites 8. Comments. Breddin (1904a) considered Edessa leptacantha related to E. pachyacantha (= H. tragelaphus). These species can be differentiated by humeral angles globose in E. pachyacantha (Fig. 20G). Other characters are subtle: expansions of ventral rim are more rounded, setae of lateral excavation of proctiger shorter, and paramere has anterior and posterior lobes more developed in H. leptacanthus than in H. tragelaphus. The female of H. leptacanthus has four parallel narrow black stripes dorsally on seventh and eighth segments not found in H. tragelaphus. Distribution (Fig. 23). PERU: Oxapampa.

Species belonging to H. triangularis group can be identified by the general and uniform green color (Fig. 19H,J) (except H. triangularis), except for a median large yellow spot on abdominal venter (Fig. 19F); and typically, without any transversal dark stripe on ventral surface (Fig. 19F,H,J). This group also doesn’t have the anterolateral margin of pronotum black (Fig. 19E,G,I). Doesn’t have a transversal dark stripe on pronotum, except H. triangularis, that is a striking characteristic of the rest of the species groups of Hypoxys. Connexivum without black spots (Fig. 19E,G,I). Males have the head of paramere usually with a single lobe elongated and anteriorly directed (Fig. 9B).

Anterolateral margin of pronotum with incomplete solid black stripe (Fig. 19K). Dark marks on posterior part of pronotum (Fig. 19K) varying from small, elongated, lateral black spots (including posterolateral angles), to an incomplete or complete stripe; stripe usually smoky brown, rarely solid black. Connexivum uniformly green or with small median yellow spots, sometimes also brown spots on excavated areas. Anterolateral margin of pronotum punctured. Anterior margin of scutellum concolorous (Fig. 19K). Dorsal surface of abdomen brown. Ventrally apex of pseudosutures with or without rounded dark spots (Fig. 19L). Male (Fig. 12 A–C). Pygophore with dorsal rim shallowly excavated, central part straight; lateral strongly projected posteriorly, surpassing posterolateral angles and expansions of ventral rim (Fig. 12A,B). Paramere with anterior lobe triangular, long, reaching base of proctiger; posterior lobe slightly developed and acuminate (Fig. 12B). Proctiger with widely separated tufts of dense setae dorsally; posterior face rounded and flat (Fig. 12B). Ventral rim with expansions well developed, barely tumid, and acuminated (Fig. 12C). Female (Fig. 12D). Gonocoxites 8 inner angle reaching base of gonocoxites 9. Laterotergites 9 narrow, clearly surpassing sclerite uniting laterotergites 8. Comments. This species has a curious history. The complement of the description was published ahead of the original description of the species (Breddin 1904a, 1904b, 14 June and 1 July, respectively). Breddin (1904b) compared E. oxyacantha to E. nigrispina and E. melacantha; and Breddin (1904a) compared E. oxyacantha to E. pachyacantha. Hypoxys oxyacanthus can be differentiated from E. nigrispina and E. melacantha by the humeral angles shorter and laterally directed (longer and curved backwards in E. nigrispina and E. melacantha), and corium variegated (unicolorous in E. nigrispina and E. melacantha). Here, the specie E. pachyacantha is considered a junior synonym of H. tragelaphus. Hypoxys oxyacanthus can be separated from H. tragelaphus by the humeral angles longer and rounded in H. tragelaphus (Fig. 19K and 20G). Moreover, males of H. tragelaphus presents projections of parameres more developed than H. oxyacanthus (Fig. 16B and 12B). Hypoxys oxyacanthus is closely related to H. leptacanthus and H. tragelaphus by sharing a projection of the dorsal rim that extends beyond posterolateral angles (Figs. 12A, 15A, 16A). This species shows a strong variation among specimens in characters usually not variable, but male and female genitalia do not support the split of the species. A future molecular analysis may help to elucidate if Hypoxys oxyacanthus is a complex of species or only a species with strong variation in a few characters. Distribution (Fig. 23).

Male (Fig. 5 A–C). Pygophore with dorsal rim widely excavated (Fig. 5A). Superior process of genital cup short, half-moon shaped; next to dorsal rim (Fig. 5B). Paramere with a single lobe curved anteriorly, tapering and elongated, margin rounded; stalk cylindrical with a small carina on inner side continuing along anterior lobe (Fig. 5B). Proctiger with laterodorsal tufts of setae separated by wide ridge; posterior face ogival (Fig. 5B,C). Ventral rim with expansions rounded, slightly tumid, short, almost level with posterolateral angles in ventral view (Fig. 5C); base of each expansion with a conspicuous transverse carina (Fig. 5A,B). Female (Fig. 5D). Gonocoxites 8 posterior margin sinuous, slanting, inner angle rounded; sutural border divergent from basal third, gonapophyses 8 slightly exposed. Comments. The male is described here for the first time. Breddin (1907) considered Edessa eburatula closely related to E. jugalis, which is synonymized with H. quadriden s here. Actually, Hypoxys eburatulus is closely related to H. dolosus. Both species can be separated by expansions of ventral rim smaller in H. eburatulus (Fig. 5C) than in H. dolosus (Fig. 4C). Superior process of the genital cup is very similar in the photos presented here, but in H. eburatulus ventral part of the process is as long as dorsal part (Fig. 5B); in H. dolosus ventral part is much longer than dorsal one (hidden by paramere in Fig. 4B), dorsal part looks more a transverse crest as described above. Paramere is also very similar, but in H. dolosus the developed inner carina gives a triangular shape to the head of paramere (Fig. 4B), while in H. eburatulus the tiny carina does not interfere and the head looks convex (Fig. 5B). Genital plates are very similar and do not show reliable characters. The distribution is the best way to separate both species because H. eburatulus is the only species of the genus found in Central America (Fig. 21). Distribution (Fig. 21).

I: 0.7–0.8; II: 1.9–2.1; III: 1.2–1.3; IV: 4.0–4.2; V: 5.0; interocular distance: 1.4–1.7; scutellum length: 7.8–7.9; scutellum width: 5.7–5.8; pronotal length: 3.4–3.7. Diagnosis. Anterolateral margin of pronotum without solid black stripe. Pronotum with a transversal solid black stripe covering almost entire posterior margin (Fig. 20C); posterolateral angle developed laterally, slightly short- er than interocular distance. Connexivum completely green (Fig. 20C). Anterolateral margin of pronotum gently curved and punctured. Anterior margin of scutellum concolorous (Fig. 20C). Black spot of costal margin reaching approximately 1/3 of corial extension. Dorsal surface of abdomen yellow or green with brown longitudinal stripe mesially. Ventrally apex of pseudosutures without rounded dark spots (Fig. 20D). Male (Fig. 14 A–C). Pygophore with dorsal rim concave (Fig. 14A). Paramere with anterior lobe very short and truncate; posterior lobe short and acuminate (Fig. 14B). Proctiger with moderately separated tufts of setae, compared with widely separated tufts of setae in H. oxyacanthus; posterior face ogival and flat (Fig. 14B). Ventral rim with expansions little developed, flat, and acuminate (Fig. 14C). Female (Fig. 14D). Gonocoxites 8 posterior margin straight; sutural border contiguous; inner angle not developed. Gonocoxites 9 slightly convex; margin rounded. Laterotergites 9 barely surpassing sclerite uniting laterotergites 8. Comments. Like in H. oxyacanthus the complement of E. infulata description was published ahead of the original description of the species (Breddin 1904a, 1904b, 14 June and 1 July, respectively). In both publications Breddin considered the species related to E. quadridens. Hypoxys infulatus is easily separable by projected humeral angles and connexivum uniformly green, without dark spots on segments III–VI (short humeral angles and connexivum spotted in H. quadriden s ). The male is described here for the first time. Distribution (Fig. 23). BRAZIL: Rondônia; PERU: Huánuco; BOLIVIA: La Paz.

Group H. oxyacanthus (Figs. 12–16 A–E; 19 K–L, 20 A–H; 23) Diagnosis. Pronotum and scutellum with brown punctures of the same size, uniformly distributed, and never on dark spots (Figs. 19K, 20A, C, E, G). Spots on pronotum usually restricted to narrow, short, transverse spots close to each humeral angle, these spots can become incomplete stripes, or complete smoky brown stripes in H. oxyacanthus (Fig. 19K), or complete solid black stripes in H. infulatus (Fig. 20C). Connexivum without large black spots that extend ventrally as in H. quadriden s group (Fig. 18A); usually green with yellow median spot; green part can turn brown or yellow in specimens not well preserved. Body lighter ventrally than dorsally, transversally striped in green and yellow, sometimes green stripes turn light brown (maybe a preservation problem) (Fig. 20B,D,F). Metasternal process with anterior arms more tumid than in H. quadriden s group species. Pygophore with superior process of genital cup subtriangular, deeply excavated black, close to proctiger, and a little further from dorsal rim than in H. quadriden s group. Margin of diaphragm, at base of proctiger, with row of setae. Paramere with head pyramidal; shaft with carina on inner side that splits distally in an arch uniting anterior and posterior apex (Fig. 12B); anterior lobe somewhat elongated and rounded; posterior lobe laterally directed. Ventral rim central excavation shallowly excavated; expansions surpassing level of posterolateral angles in ventral view (Figs. 12–16C). Females with genital plates very similar and are hard to separate, except H. infulatus (Fig. 14D). Gonocoxites 8 typically with posterior margin straight or slightly sinuous and slanting; and sutural border divergent on distal half; inner angle rounded and overlapping base of gonocoxites 9. Head. Mandibular plates with apex concolorous; lateral margin without spot. Antennae yellow to brown with setae more densely distributed on antennomeres IV and V; second antennomere longer than third (Figs. 19K, 20A,C,E,G). Thorax. Apex of humeral angle with margin black and slightly curved posteriorly (Fig. 20C). Cicatrices with concolorous punctures delimiting anterior sulci. Scutellum with apex not punctured. Black spot of costal margin reaching approximately 1/4 of corial margin. Propleura with a green stripe on anterolateral margin; punctures concolorous or brown. Evaporatorium rugulose, concolorous to whitish (Fig. 20B). Metasternal process (Fig. 19F) with anterior bifurcation receiving fourth and half of the third rostral segment. Abdomen. Connexivum with punctures concentrated in two excavated areas separated by median yellow callous (Fig. 20A, C, E, G). One trichobothrium positioned in line with spiracles and the other located laterad of this line. The group H. oxyacanthus is composed of Hypoxys oxyacanthus, H. brachyacanthus, H. infulatus, H. leptacanthus, H. tragelaphus, and a few new species., Published as part of Nunes, Benedito Mendes, Campos, Lourival Dias, Mendonca, Maria Thayane Da Silva, Cunha, Eduardo Victor De Paiva & Fernandes, Jose Antonio Marin, 2020, Revision of Hypoxys Amyot & Serville, 1843 stat. rest.

Black spot on costal margin of corium reaching approximately 1/5 of corial extension. Dorsal surface of abdomen pale yellow with lateral margins of last two segments brown. Connexivum with few concolorous punctures (Fig. 19G). Male (Fig. 10 A–C). Pygophore with dorsal rim shallowly excavated (Fig. 10A). Superior process of genital cup elliptic and narrow (Fig. 10B). Paramere large; anterior lobe triangular; posterior lobe triangular and slightly curved laterally (Fig. 10A,B). Proctiger with narrow, shallow lateral excavation; excavation setose, including wide ridge separating lateral excavations; posterior face rounded, flattened and coarsely rugose (Fig. 10B). Ventral rim central excavation widely open; expansions little developed, rounded, almost level with posterolateral angle in ventral view (Fig. 10C). Female (Fig. 10D). Gonocoxites 8 (gc8) with posterior margin arched; sutural border with distal half divergent in an open “U” (Fig. 10D). Gonapophyses 8 strongly exposed. Comments. Breddin (1904a) considered Edessa capito close to E. meditabunda, but apex of scutellum and humeral angles in E. meditabunda are rounded (acute in H. capito) and arms of metasternal process are laterally flattened in E. meditabunda (tumid in H. capito). Among the species included in H. triangularis group, H. capito is the smallest one. The male is described here for the first time. Distribution (Fig. 22). PARAGUAY: Cordillera, Central, Paraguarí.
