TYPE LOCALITY. — Brazil, State of Minas Gerais, municipality of Chapada Gaúcha, Parque Nacional Grande Sertão Veredas.

ETYMOLOGY. — Name after the Brazilian novelist João Guimarães Rosa, author of the novel “Grande Sertão: Veredas”.

TYPE MATERIAL. — Holotype. Brazil • ♂; MG, Chapada Gaúcha, P [arque] N[acional] Grande Serão Veredas ; 15°11’S, 45°39’W; 3-9. II.2018; P. G. B Souza-Dias, L. D. Campos , M. D. de Santis and D. M. A. Garcia leg.; genitalia removed and kept with the specimen; right foreleg removed for DNA extraction; preserved in ethanol 80%; LDC_047; MZSP.

Allotype. Brazil • ♀; same data as for holotype; copulatory papilla dissected and kept with the specimen; left foreleg removed for DNA extraction; preserved in ethanol 80%; LDC_048; MZSP.

DIAGNOSIS. — Each sternite with two blackish points, close to lateral margin. Male: Metanotum with one pair of median elliptical projections and one pair of rounded projections close to the caudal margin; two clusters of central bristles, one pointing to caudal margin, other pointing to cephalic margin. FWs not covering last three abdominal tergites, lateral borders very sclerotized, yellowish; region between anal veins well sclerotized, yellowish. Stridulatory apparatus: hv not connected to CuPa; first very reduced, third and fourth connected apically; mirror distal cell divided by a longitudinal vein. Male genitalia: MLophi triangular; LLophi very reduced, tip rounded in dorsal and ventral views; EctF anterior portion concave, forming lateral lobes in anterior and ventral views, posterior portion thinner, upcurved to dorsal, almost reaching MLophi apex, apex inflated; endophallic apodemes long as EndSc, curved inwards in dorsal and ventral views.

In addition to the characters of the genus

Body. Size medium. Head and pronotum general coloration reddish brown, abdomen dark brown almost black; body covered by brownish bristles.

Antennal scape with few bristles on the distal margin in frontal view, light brown, with a medium to dark brown maculae on distal portion in frontal view ( Fig. 2C ); antennomeres light to medium brown with some isolated antennomeres dark brown. Frons light brown with a median triangular and dark brown macula in frontal view ( Fig. 2C ). Gena light brown, marmored medium brown in frontal and lateral views. Mandibles yellowish brown. Clypeus light brown, whitish laterally, with two median stripes medium brown; labrum whitish, lower margin yellowish brown ( Fig. 2C ). Maxillary palpi slightly pubescent, light brown, marmored medium brown; articles 3-5 elongated, article 3 the longest, articles 4 and 5 almost same-sized; apex of article 5 whitish ( Fig. 2B, C ).

Pronotum. DD yellowish brown; median maculae dark brown, almost black, one close to the cephalic margin, “T” shaped, one in the middle of DD, rounded; caudal margin medium to dark brown. DD cephalic margin almost straight, DD caudal margin slightly convex ( Fig. 2A, B ).

Legs. Legs I and II pubescent. FI and FII pale brown, medium to dark brown punctuated; TI and TII darker. FIII pubescent, light brown, medium to dark brown apically; TIII medium to dark brown, yellowish brown ventrally; TI, TII, TIII composition of subapical and apical spurs same as the genus description ( Fig. 2H, I ). Basitarsus III pale brown, medium brown ventrally.

Abdomen. Tergites dark brown, almost black; with two bands, thin, median, longitudinal, light brown. Sternites medium brown; each sternite with two dark points, close to the lateral margin. Cerci pilose, light to medium brown.

Male

Metanotum lighter than pronotum DD; metanotal projections: median pair as in Fig. 2 Ea, caudal pair as in Fig. 2 Eb; clusters of bristles as in Fig. 2E . FWs long, covering hindwings, mainly medium brown; dorsal and lateral field divided by very sclerotized vein (M + CuA vein), yellowish; anal vein area well sclerotized, yellowish; harp crossed by four diagonal veins, not connected to CuPa; first very reduced, third and fourth connected apically; CuPb short; mirror distal cell divided by a longitudinal vein; apical field reduced ( Fig. 2A, D ); lateral field with c. 15 diagonal, parallel veins ( Fig. 2B ). Supra anal plate slightly pubescent, dark brown, lateral-anterior maculae median to light brown, median maculae light brown; anterior and posterior margins almost straight ( Fig. 2F ). Subgenital plate medium to dark brown; lateral-posterior boarders yellowish-brown; anterior margin almost straight, posterior margin convex ( Fig. 2G ).

Male genitalia ( Figs 3 A-C; 4)

Pseudepiphallus: MLophi apex pointed, longer than LLophi in dorsal view; LLophi tip rounded in dorsal and ventral views. PsP short, posterior half two times wider than anterior half in ventral view; R straight in dorsal and ventral views, anterior half slightly curved in lateral view; almost connected to pseudepiphallic sclerite. Ectophallic invagination: EctAp, half size of R, curved outwards in dorsal and ventral views; ventral projections of ectophallic invagination slightly curved outwards in ventral view; EctF anterior portion concave, forming lateral lobes in anterior and ventral views, posterior portion thinner, upcurved to dorsal, almost reaching MLophi apex, apex inflated. Endophallus: endophallic longer than wide, concave in ventral view; endophallic apodeme as long as EndSc, curved inwards in dorsal and ventral views.

Female

General color as in male. FWs not covering last four abdominal tergites, slightly translucent, medium to light brown ( Fig. 2J ). Supra anal plate similar to the male, lighter ( Fig. 2K ). Subgenital plate wider than long, medium brown; posterior margin concave forming two lateral lobes light brown ( Fig. 2L ).
