Description

Description. Head (Fig. 6 B): with a transverse wide black band extended over the vertex, covering the region of ocellus and reaching the apex of the postclypeus; two black vittae in " V " at the posterior margin of the head (the base concealed by the pronotum); base of eyes marked with black; anterior margin of head slightly convex; antenna with a tawny scape and flagellum, and the pedicel black; a black band below each antenna reaches the posterior margin of the eyes; postclypeus (Fig. 6 C) unmarked, oval in ventral view and flat in lateral view, the apex not prominent in dorsal view relative to the supra-antennal plates; longitudinal groove slender and shallow; anteclypeus and carina tawny; lorum black; rostrum with a tawny mentum and labium; labium short, reaching the base of basisternum 3 black at the apex. Pronotum (Fig. 6 B): with lateral and sub-lateral lobes with wrinkles; ambient fissure with a black band in the middle. Mesonotum (Fig. 6 A): lateral and submedian sigillae marked with black; scutal depression marked with black; basisternum 3 (Fig. 6 D) with very developed protuberances relative to the median insertion, closely spaced forming an acute angle; posterior margin in an obtuse angle; cruciform elevation not covering tergite 1; apex of the posterior projections of the cruciform elevation obtuse; operculum (Fig. 6 E) obtuse and long, covering the timbal cavity and the apex reaching the auditory capsule, the internal angles short, and the apices obtuse and widely spaced, anteromedian margin concave anteriorly to internal angle, the lateral margin convex, posterior margin slightly concave; meracanthus reaches the posterior margin base of the meracanthus marked with black, gutter present in all margins; legs tawny; wings hyaline; forewings: basal cell opaque, basal vein of the second apical cell oblique; hindwings: radius vein straight. Abdomen subcylindrical, the length is equivalent to the combined length of the head and thorax in dorsal view (Fig. 6 A); timbal cover (Fig. 6 F) flat and long, apex acute, almost reaching the lateral metascutellar plate, middle third of anteromedial margin concave, ventral anterior margin slightly concave (near the posterior margin of the operculum); tergites 2 to 8 marked with black anteriorly; sternite VII (Fig. 6 G) sub-triangular, the lateral margin concave, becoming convex, the posterior margin emarginate. Uncus (Fig. 6 H, I): lateral margin straight becoming convex in the ventral apophyses; lateral branches of uncus undeveloped, convex bud-like, the internal margin slightly concave; ventral apophyses grooved, ventrally developed originating from below the lateral branches of uncus; internal margin forming a sub-rectangular distally directed; posterior margin forming an acute angle posteriorly directed. Pygofer (Fig. 6 J) sub-cylindrical; the basal lobe long, almost reaches the apex of ventral apophyses. Theca (Fig. 6 K-M) dorsally developed with a ventral thecal process; vesica originates in a fissure at the distal third of the theca; vesica extruded and ornamented with cornuti in both the inner and outer surfaces. - Female (Fig. 7 A - E): The female presents the same somatic characteristics as the male (Fig. 7 A) except the operculum (Fig. 7 C) is smaller; sternite VII (Fig. 7 D) longer with a straight lateral margin and a concave posterior margin with an obtuse middle groove; dorsal beak of segment 9 with the same length as the ovipositor sheath (Fig. 7 E). The ovipositor bears six teeth.
