Acrogonia quintasi sp. nov.

( Figures 19–25 )

Total length. Male holotype 9.7 mm; female unknown.

Holotype description. Head and thorax. Structural features of head and thorax much as described above for A. falcata sp. nov., except pronotum more elongated and with posterior margin narrowly emarginate medially, pronotal disc without rugae, and forewings translucent.

Color. Crown and mesonotum ( Fig. 19 ) dark brown to black. Crown ( Fig. 19 ) with few irregular yellow dots on anterior margin. Pronotum ( Fig. 19 ) with black transverse band on anterior margin and brownish-orange disc. Mesonotum ( Fig. 19 ) with white apex. Forewing ( Figs. 19–20 ) translucent; veins brown. Face and lateral and ventral portions of thorax ( Fig. 20 ) mostly dark brown to black; frons with pair of large yellow areas on inferior portion. Labium, labrum, and legs ( Fig. 20 ) mostly yellow with some brown portions.

Male genitalia. Pygofer ( Fig. 21 ), in lateral view, strongly produced posteriorly, expanded apically; apex dorsally concave. Subgenital plate ( Fig. 22 ), 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; without “articulated” portion; in lateral view, plate extending almost as far posteriorly as pygofer apex. Connective ( Fig. 23 ), in dorsal view, Y-shaped but with arms poorly developed, so that it looks somewhat linear; stalk narrow and elongate, with dorsal median keel more developed on basal third. Style ( Fig. 23 ), in dorsal view, extremely elongate, extending posteriorly much farther than apex of connective, as far posteriorly as apex of subgenital plate; without distinct preapical or median lobe; apex acute. Aedeagus ( Fig. 24 ) slightly asymmetrical; shaft, in lateral view, elongate, bifid, with one ramus located above the other (superior ramus serrated dorsally); each ramus with acute apex. Anal tube ( Fig. 25 ) without processes; basal apodemes each with small digitiform projection directed to midline.

Female unknown.

Etymology. The name of the new species, quintasi , refers to the graduate student Victor Marcos Cordeiro Quintas in recognition of his friendship and contribution to the Setor de Hemiptera (Departamento de Entomologia, Museu Nacional, UFRJ, Rio de Janeiro).

Type material. Holotype: male, “ Brasil [state of] Pará \ Serra Norte \ SERRARIA \ 19-x-1984 ” ( MPEG).
