Acrogonia dentata View in CoL sp. nov.

( Figures 33–51 View FIGURES 33–40 View FIGURES41–51 )

Total length. Male holotype 9.8 mm; male paratypes 9.2–10.5 mm (n = 11); female paratypes 10.2–10.5 mm (n = 3).

Holotype description. Head and thorax. Structural features of head and thorax much as described above for A. falcata sp. nov., except pronotal disc without rugae, posterior margin of pronotum strongly concave, and forewings translucent.

Color. Crown, anterior portion of pronotum, and mesonotum ( Fig. 33 View FIGURES 33–40 ) dark brown to black with dispersed, irregular yellow spots; disc of pronotum ( Fig. 33 View FIGURES 33–40 ) brown with green spots; mesonotum ( Fig. 33 View FIGURES 33–40 ) with yellow markings and white apex. Forewing ( Figs. 33–34 View FIGURES 33–40 ) translucent, except small yellow markings and small brown area at base; veins brown with yellow portions. Face ( Fig. 34 View FIGURES 33–40 ) dark brown to black; frons with three large, almost confluent whitish-yellow areas, two inferior and one superior. Lateral and ventral portions of thorax ( Fig. 34 View FIGURES 33–40 ) dark brown to black with large whitish-yellow areas; labium, labrum, and legs ( Fig. 34 View FIGURES 33–40 ) mostly yellow with brown portions.

Male genitalia. Pygofer ( Fig. 35 View FIGURES 33–40 ), in lateral view, strongly produced posteriorly, expanded apically; dorsoapical margin forming lobe. Subgenital plate ( Fig. 36 View FIGURES 33–40 ), in ventral view, subtriangular; base with lateral projection directed anteriorly (central emarginate area between pair of projections covered by valve); basal third slightly expanded laterally, then tapering gradually towards apex; latter curved dorsally; without “articulated” portion; in lateral view, plate extending almost as far posteriorly as pygofer apex. Connective ( Fig. 37 View FIGURES 33–40 ), in dorsal view, T-shaped but with arms poorly developed, their combined size similar to expanded apex of stalk, so that it looks somewhat like an “I”; stalk narrow and very elongate, without dorsal median keel. Style ( Fig. 37 View FIGURES 33–40 ), in dorsal view, extremely elongate, extending posteriorly much farther than apex of connective, almost as far posteriorly as apex of subgenital plate; without distinct preapical or median lobe; apex acute. Aedeagus ( Figs. 38–39 View FIGURES 33–40 ) symmetrical; shaft elongate, bifid, curved dorsally, apical portions of rami expanded and armed with denticles. Anal tube ( Fig. 40 View FIGURES 33–40 ) without processes.

Female. Genitalia. Sternite VII ( Figs. 41–42 View FIGURES41–51 ) bilobed; posterior margin with deep median emargination. Pygofer, in lateral view, produced posteriorly; apex obtuse. Valvifer I ( Figs. 43–44 View FIGURES41–51 ), in lateral view, subrectangular. Valvula I ( Figs. 43–44 View FIGURES41–51 ), in ventral view, slightly expanded basally; in lateral view ( Fig. 43 View FIGURES41–51 ), with distinct ventral lobe (VLB) on basal half; ventral interlocking device (VID) short, located on basal half of blade; dorsal sculptured area ( Figs. 45–46 View FIGURES41–51 ) extending from basal portion of blade to apex, formed mostly by scale-like processes arranged in oblique lines; ventral sculptured area ( Fig. 47 View FIGURES41–51 ) restricted to apical portion, formed mostly by scale-like processes; blade apex acute, dentiform. Valvula II ( Fig. 48 View FIGURES41–51 ), in lateral view, with dorsal margin convex; preapical prominence strong and apex obtuse, apical margin between them concave ( Figs. 48, 51 View FIGURES41–51 ); about 14 teeth distributed continuously on posterior 2/3 of dorsal margin, most teeth ( Figs. 48–50 View FIGURES41–51 ) triangular with ascending portion (= anterior edge) short, descending portion (= posterior edge) long; blade with ducts extending to apical portion and to teeth or terminating below latter. Gonoplac, in lateral view, with basal half narrow and apical half distinctly expanded; apex obtuse.

Intraspecific variation. The disc of the pronotum may present green or yellow spots, or it may be more uniformly brown. The mesonotum may present only small yellow spots, or a transverse yellow area on scutellum, or a large yellow area on central portion of scutum and scutellum.

Etymology. The name of the new species, dentata , refers to the denticles of the aedeagal rami ( Figs. 38–39 View FIGURES 33–40 ).
