Type locality. Brazil, Bahia State, municipality of Mucuri.
Etymology. Ọ ṣọ́ ̀ ọ gỳ(Oxóssi in portuguese) is an orisha of the Yoruba religion in West Africa, and the canbomblé in Brazil. Oxóssi is the spirit associated with the animals, forests, and hunt. Distribution. Atlantic Forest, in Bahia State, municipality of Mucuri.
Type material. Holotype, allotype, 1 male paratype. Holotype: male, with genitalia removed and kept with the specimen, and the right leg II missing, labeled “ Brasil, BA [Bahia]. Mucuri, Faz. Farol. 14-16/vii/1989. 2-M. 89/ 81. F.A.G. Mello col.” (BOTU). Allotype: female, with the copulatory papilla removed and kept with the specimen, labeled “ Brasil, BA [Bahia], Mucuri, Fazenda Farol - mata. i-96. 18o04’01’’S/39o40’23”W. F.A.G. Mello & S.S. Nihei, leg. 5-M” (BOTU). Paratype. 1 male with left leg I missing, and the genitalia and FWs removed and kept with the specimen, same data as the holotype (BOTU).
Diagnosis. Species large, but smaller than T. salgado n. sp. (~ 3cm body length), general coloration light to yellowish brown. Male genitalia: anterior margin of pseudepiphallic sclerite without medial furrow; lateral lophi bifurcated, inner projection pointed, spine-like; medial lophi below inner margins of lateral lophi; pseudepiphallic parameres thin, shorter than in T. salgado n. sp., apex rounded. Female. General coloration darker than males: body light brown, head and pronotum medium brown. Copulatory papilla small, rounded; base convex dorsally, with medial invagination, medially extended ventrally; apex membranous, rounded, smaller than in T. salgado n. sp., as in Figs. 10 A–C.
Description. In addition to the characters of the genus:
General coloration light to yellowish brown (Figs. 1B, 7A, 8A). Head. Head large, wider than long, yellowish brown (Figs. 7A, B). Posterior margin of occiput yellowish brown, with 4 lines going from occiput to vertex (Figs. 1B, 7A, B). Occiput and vertex glabrous (Figs. 1B, 7A, B, C, I, 8A). Eyes small, with very reduced unpigmented area on dorsal margin (Figs. 7B, C, I). Fastigium glabrous, wide as vertex, at least 2x wider than antennal scape (Figs. 1B, 7A, B, C, I). Antennal scape and antennomeres light brown (Figs. 1B, 7A–C, I). In lateral view, gena yellowish brown (Fig. 7C). Three ocelli, almost in line; lateral ocellus small, circular; median ocellus small, flat (Figs. 7C, I). Maxillary palpi light brown; apex rounded, whitish. Frons light brown, very short, shorter than clypeus (Fig. 7I). Clypeus, labrum and mandibles light brown (Fig. 7I).
Thorax. DD saddle-shaped, glabrous, wider than long, light brown, with medium brown maculae; cephalic margin concave, caudal margin almost straight (Figs. 1B, 7A–C, 8A). LL ventro-cephalic angle and ventral margin rounded, ventro-caudal angle ascendant (Fig. 7C).
Legs. Legs I, II light brown (Figs. 1B, 7A). TI with two auditory tympana, two ventral spurs and one dorsal (inner). TII with 4 spurs. Legs III not specially elongated, shorter than body length. FIII light brown, with longitudinal medium brown line; FIII medium brown in the articulation with TIII. TIII and basitarsus–III light brown. Double row of spines on basitarsus–III. TIII with spines before the subapical spurs; subapical spurs 3/3. Apical spurs: median longest on both sides, dorsal slightly shorter, ventral smaller.
Abdomen. Abdomen light brown, glabrous; cerci light brown (Figs. 1B, 7A).
Male. Male FWs reaching tergite 4, medium brown; anal vein area bulged dorsally; harp crossed with 4 almost transverse veins; stridulatory vein with 102 teeth (n=1); mirror undivided, distinct from apical venation; apical field very short, almost reduced; lateral field with 4-5 longitudinal veins (Figs. 1B, 7A, D–F, 13A). Metanotum without metanotal structures. Male supra anal plate light brown (Fig. 7G). Subgenital plate light brown, shieldshaped, proximal margin almost straight, distal margin rounded, extended medially (Fig. 7H). Male genitalia.
Pseudepiphallus: anterior margin without medial furrow (Figs. 9A, D, F); lateral lophi bifurcated, inner projection pointed, spine-like (Figs. 9A, B D); medial lophi below inner margins of lateral lophi (Figs. 9A, D, F). Rami elongated, apically bent towards ventral side; apex of each ramus separated (Figs. 9–C). Pseudepiphallic parameres thin, shorter than in T. salgado n. sp., apex rounded (Figs. 9B, E). Ectophallic invagination: ectophallic apodemes shorter than in T. salgado n. sp. (Fig. 9A); ectophallic arc dorsal, thin, almost indistinguishable, below pseudepiphallic medial lophi; ectophallic fold furrowed, longer than in T. salgado n. sp. and T. oxente n. sp. Endophallus: endophallic sclerite small, related to ectophallic fold (Fig. 9B); endophallic cavity reduced.
Female. Larger than male, shorter than females of T. salgado n. sp. (Fig. 8A). General coloration darker than males: body light to medium brown; head and pronotum medium brown (Fig. 8A). FW small, very reduced (Figs. 8A, B). Abdomen glabrous, yellowish to medium brown (Fig. 8A).

Subgenital plate small, proximal margin almost straight, distal margin medially convex, angles rounded (Fig. 8D). Ovipositor short, shorter than FIII; apex of ovipositor modified, with conspicuous concavity; apex pointed and curved in lateral view, with ventral protuberance, as in T. salgado n. sp. (Figs. 8E–G).
