Description.

Large size for the species group, especially for females. General coloration dark brown with yellow areas. Head dorsum almost homogeneously dark brown ( Fig. 5M ). Fastigium dark brown to black. Scapes yellow brown, dark brown basally. Antennae brown. Face mostly brown, with 2 parallel dark brown stripes on front part of fastigium (not visible in HT) and a yellow transverse band below eyes. Mouthparts yellow brown. Maxillary palpi yellow brown, darker apically. Pronotum: Dorsal disk dark brown faintly mottled with yellow brown, the 4 corners yellow; lateral lobes almost entirely dark brown, ventral corners yellow brown. Legs homogeneously orange brown, hind knees dark brown. Hind wing tail dark brown.

Male: FW coloration mostly brown with yellowish areas. Yellow areas include: bases of CuA, veins 2A–4A, transverse part of 1A, chord veins, anterior part of diagonal vein, harp veins, and oval area posterior to mirror (translucent cells). Orange brown sclerotized area near base of chords. Lateral field: M/R area dark brown, veins orange brown; Sc vein and projections yellow, cells between them dark brown. FW venation ( Fig. 9H ): 1A slightly bisinuated. CuP missing. Stridulatory file with 221 teeth on the transverse part of the file, and 13 on a ventral bump near base of 1A. Harp with 2 w-shaped harp veins. Mirror area: mirror (d1) longer than wide, oval, well defined, crossed by an accessory vein near mid-length, the posterior part crossed by several transverse veins; d2 not distinctive; e1 crossed by transverse accessory veins. Apical field with 5 cell alignments posterior to mirror (n = 1). Lateral field with 10 projections of Sc and 4 more ventral veins. Subgenital plate dark brown.

Male genitalia ( Fig. 37 EG): Pseudepiphallic dorsal ridges almost parallel, their dorsal edges setose, carinated on dorso-external edges and slightly asymmetrical, the left one thicker; forming a homogeneous curve in lateral view ( Fig. 37G ). Pseudepiphallic sclerite with wide latero-anterior expansions, membrane between them not setose. Posterior region of pseudepiphallus rounded, with a small rounded translucent area. Posterior lobe of Pseudepiphallic parameres curved externally, their bases very sclerotized. Rami strong, apical expansion oriented posteriorly. Ectophallic arc complete, curved, without a posterior expansion. Ectophallic fold membranous, with weak lateral sclerites. Endophallic sclerite with short posterior arms and a wide posterior expansion. Endophallic apodeme with a large medio-dorsal crest and lateral lamellas. Membrane of endophallic cavity plicate.

Female: Size large for the genus. FW coloration dark brown (cells and veins), their bases yellow brown, including bases of anal veins and CuA and first quarter of M. CuP orange brown, very strong. Yellow brown area near FW mid-length including part of CuA and M and surrounding cells and transverse veins. R/Sc area and veins dark orange brown, with many transverse veins; posterior part of Sc yellow brown. Projections of Sc and more ventral veins yellow, their bases dark brown, the cells between them dark brown. FW venation ( Fig. 11E ): 13–14 (n = 2) strong longitudinal veins on dorsal field; lateral field with 10–11 (n = 2) longitudinal veins including 6 projections of Sc and 4–5 ventral veins. Ovipositor long, apex with both dorsal and ventral edges denticulate, ventral valves with two preapical notches ( Fig. 13J ).

Female genitalia ( Fig. 14J ): Copulatory papilla trapezoidal, ventral part raised, apex slightly curved ventrally and sclerotized.

Juvenile: Unknown.
