Etymology.

The specific name refers to the olive green color of the species. Latin: oliva, olive.

Diagnosis.

The species can be distinguished from all other species of Acanthoventris gen. nov. by the following combination of features: body green; anterior margin of head tightly concave; apex of postlypeus slightly prominent in dorsal view relative to the anterior margin of head; timbal cover wide, almost covering the timbal cavity; sternite VII sub-rectangular; posterior margin of ventral apophyses forming a turned-back rim sclerotized and an acute angle posteriorly directed. This species has a similar morphology to A. iara sp. nov. due the anterior margin of head tightly concave, but can be distinguished by the operculum covering the timbal cavity and the apex reaching the auditory capsule, and by the diagnostic characters referred above.

Color.

Body green with head, thorax and abdomen marked with black.

Description.

Head (Fig. 17 B ): with a transverse wide black band departing from each eye, covering the posterior margin of eyes and the ocelli, reaching the apex of the postclypeus; silver setae in the posterior margin of eyes; anterior margin of head tightly concave; antenna with a green scape, pedicel and flagellum dark castaneous; anterior margin of head slightly convex; postclypeus (Fig. 17 C ) unmarked and oval in ventral view, flat in lateral view, the apex slightly prominent in dorsal view relative to the anterior margin of head, longitudinal groove slender and shallow; anteclypeus black and carina green; lorum black; mentum green; labium short, reaching the base of basisternum 3 (Fig. 17 D ). Pronotum (Fig. 17 B ): pronotal collar green with pilus silver setae. Mesonotum (Fig. 18 A ): submedian, lateral sigillae and scutal depression marked with black; basisternum 3 (Fig. 17 D ) with well-developed protuberances relative to the median insertion, slightly salient; posterior margin tightly angled; cruciform elevation not covering tergite 1; apex of the posterior projections obtuse; operculum (Fig. 17 E ) obtuse and long, covering the timbal cavity and the apex reaching the auditory capsule, the internal angles very short, the apex obtuse and widely spaced, anteromedian margin concave anteriorly to the internal angle and marked with black, lateral margin convex, the posterior margin slightly straight; meracanthus reaches the posterior margin; gutter present in all margins; legs green marked with olive-green; wings hyaline; forewings: anterior portion of the basal cell slightly opaque; hindwings: radius vein straight. Abdomen (Fig. 17 A ) subcylindrical, the length equivalent to the combined length of the head and thorax in dorsal view; timbal cover (Fig. 17 F ) flat and wide, almost covering the timbal cavity, apex obtuse reaching the lateral metascutellar plate; middle third of anteromedial margin concave, ventral anterior margin tightly concave (away from the posterior margin of operculum); tergites 3 to 7 green with the anterior margin marked with black; sternite VII (Fig. 17 G ) sub-rectangular, the lateral margin convex becoming straight toward the apex, the posterior margin slightly emarginate. Uncus (Fig. 17 H, I ): lateral margin slightly sinuous becoming convex in the ventral apophyses; uncal dorsal crest fused and dorsally projected; lateral branches of uncus undeveloped, convex bud-like, the internal margin slightly straight; ventral apophyses grooved, ventrally developed originating from below the lateral branches of uncus, internal margin forming a sub-rectangular distally directed; posterior margin forming a turned-back rim sclerotized and an acute angle posteriorly directed. Pygofer (Fig. 17 J ) sub-cylindrical; the basal lobe long, reaching the lateral branches of uncus. Theca (Fig. 17K-M ) dorsally developed with a ventral thecal process; vesica originates in a fissure at the distal third of the theca, extruded and ornamented with cornuti in both the inner and outer surfaces; spine present on the vesica. - Female: Unknown.
