Diagnosis. -

This species differs from all congeners by male genitalia with pseudepiphallus more rectangular, very elongate, its posterior part curved posteriorly, its apex truncated with small paired apical lophi; lophi triangular with obtuse apex.

Redescription. -

Average size among congeners (Fig. 1 View Figure 1 ). Dorsum of head with broad red brown bands barely separated (Fig. 4A View Figure 4 ). Fastigium red brown (Fig. 4A View Figure 4 ). Scapes red brown with some dark patches. Fastigium verticis brown with two vertical yellow brown stripes diverging ventrad, frons brown with two yellow brown spots ventral of stripes; clypeus sometimes darkened, mouthparts yellow brown to red brown (Fig. 5A View Figure 5 ). Pronotal disk red brown with lighter lateral ovular spots near anterior half and some faint lighter spots along posterior margin (Fig. 4A View Figure 4 ). Lateral lobes of pronotum dark brown, with yellow spot at anterior ventral corner (Fig. 6A View Figure 6 ). FIs and FIIs generally yellow brown with brown spots and rings; TIs and TIIs brown with two yellow brown rings. FIIIs brown, knees slightly darker.

Male. FW reaching apex of third tergite; apex rounded. FW coloration (Fig. 7A View Figure 7 ): Dorsal field cells and veins mostly brown; area between M and R yellow brown; basal area with a wide cream-colored spot on external corner. Lateral field dark brown. FW venation typical of genus; 1A slightly bisinuate anterior to angle; oblique vein trifurcated, posterior branch straight and transverse.

Male genitalia: (Figs 8A View Figure 8 , 11A View Figure 11 , 11B View Figure 11 ) Pseudepiphallus forming a very elongate rectangle, its basal margin slightly indented in the middle, lateral margins widened basally, forming wide shoulders carrying base of rami; posterior part of pseudepiphallus narrow, distinctly curved dorsally posterior to pseudepiphallic parameres, with two short dorsal pre-apical expansions (Fig. 8A View Figure 8 ); posterior apex truncated, posterior apex with small paired lophi, triangular with obtuse apex. Rami wide, very short, way shorter than half the pseudepiphallus length, diverging anteriorly, with posterior end protruding externally. Pseudepiphallic parameres strongly bent in basal half (~90°), with posterior apex enlarged, bean shaped. Ectophallic apodemes thin, parallel, and long, reaching beyond anterior margin of pseudepiphallic sclerite. Endophallic sclerite with anterior region very short and not reaching anterior margin of pseudepiphallic sclerite, with lateral arms elongated, tongue-shaped, and longer than median expansion.

Female. FW reaching base of third tergite, with basal area with a cream-colored oblong spot without clearly defined margin, forming two indistinct spots near base and apex; lateral field dark brown (Fig. 9A View Figure 9 ).

Female genitalia: Ovipositor about as long as FIII. Copulatory papilla very small, rounded, apex folded ventrally, short, pointed; dorsal face with a sclerotized area; ventro-anterior end base forming an oval ring (Fig. 10A View Figure 10 ).
