Redescription. In dorsal view, body approximately cylindrical, wider anteriorly, tapering posteriorly, not flat. Head with crown almost rectangular, wider than long, median length of crown 1/3 of transocular width and 2/3 of interocular width; anterior margin broadly rounded, without a carina in the transition between crown and front; lateral margins adjacent to compound eyes slightly elevated, not carinate; dorsal surface smooth, without grooves, with two slightly small concavities lateral to midline close to posterior margin (tentorial pits); coronal suture absent; ocelli located in front, closer to compound eyes than to midline, above antennal ledges; in lateral view, antennal ledges oblique and slightly carinate; antennae filiform, scape and pedicel enlarged, flagellum longer than forewings; front with length approximately 1.5–2 times to its basal width, profile convex, muscle impressions indistinct; front­genal sutures reaching ocelli; apical margin of maxillary plate not extended beyond apex of clypeus; lorum small, approximately half­moon like, the inferior margin not reaching clypeus apical margin; gena usually entirely concealing proepisternum; epistomal suture distinct and complete; clypeus with lateral margins apically divergent, without medial gibbosity or tubercle, with apical margin approximately straight. Thorax with pronotum little wider than head, width between umeri little greater than transocular width, approximately equal; median length 1/3 of width between umeri; lateral margins short, anteriorly convergent, posteriorly rounded and convergent towards posterior margin; posterior margin straight, not emarginated; dorsal surface smooth, without grooves; dorsopleural carina complete, short and little evident; in ventral view, mesothorax little to moderately swollen; scutellum as long as its maximum width, with distinct preapical fold. Forewing about 3–4.5 times longer than greatest width; apex rounded and narrowed; without punctations and opaque at colored portion, except at apex, which is hyaline; venation obscure except claval suture and apical cells, not elevated; three apical cells, first larger than second, second closer to the base of the wing than third; anteapical cells indistinct; appendix very narrow. Hindwing with four apical cells and with R4+5 and M1+2 apically divergent, not fused. Metathoracic leg: femoral formula 2:2:1. Tibial row I with long setae little separated amongst themselves and intercalary setae absent; row II with long and robust setae, in form of spines, with two or more small intercalary setae present; row III with setae moderately long, distributed throughout length of tibia, with simple bases not elevated, and intercalary setae absent; row IV densely bristly, with short setae at base, becoming progressively longer towards apex. First tarsomere as long as length of two more distal together; plantar surface with two parallel rows of short setae. Male genitalia: anal tube simple, without processes. Pygofer either with dorsal processes or an elongation of terminus. Subgenital valve partially fused with subgenital plates, with weak separation among both, sometimes difficult to see; with posterior margin emarginated. Subgenital plates deep and scoop­shaped, not fused medially. Style with apex hooklike, curved ventrally. Connective cruciform. Aedeagus moderately straight or recurved, with or without lateral flaps. Female genitalia: pygofer long with anterior, ventral and posterior margins rounded; with setae on postero­ventral margin and without processes. Sternite VII, variable in form, with sclerotization in distal half. Sternite VIII absent. Valvifer I membranous and approximately rectangular. Valvulae I long and curved dorsally. Valvifer II with microsetae at articulation point. Valvulae II long, fused throughout length except apically, straight or curved dorsally. Valvulae III long with rounded apex and basal half distinctly narrowed.
