Acrogonia felixi sp. nov.

( Figures 10–18 )

Total length. Male holotype 11.0 mm; female unknown.

Holotype description. Head and thorax. Structural features of head and thorax much as described above for A. falcata sp. nov., except median length of crown slightly greater than interocular width and approximately 8/10 transocular width.

Color. Anterior dorsum ( Fig. 10 ) mostly dark green with inconspicuous yellow or brown markings; apex of crown with yellow macula bordered by pair of brown maculae; lateral margins of crown brownish-yellow with dark brown to black lines associated with muscle impressions; coronal, frontogenal, and temporal sutures dark brown to black; mesonotum with pair of basal yellow maculae. Forewing ( Figs. 10–11 ) mostly dark green, except apical membranous area. Face and lateral and ventral portions of thorax ( Fig. 11 ) mostly yellow; labium, labrum, and legs ( Fig. 11 ) brownish-yellow.

Male genitalia. Pygofer ( Fig. 12 ), in lateral view, very strongly produced posteriorly; dorsoapical portion folded inwards. Subgenital plate ( Fig. 13 ), in ventral view, with basal third broad, narrowing gradually towards slender median third; apical third digitiform, appearing articulated with median third; in lateral view, plate not extending as far posteriorly as pygofer apex. Connective ( Fig. 14 ), in dorsal view, T-shaped but also expanded apically (and thus somewhat resembling an “I”); stalk narrow, without dorsal median keel; arms broad. Style ( Figs. 14–15 ), in dorsal view, extending posteriorly farther than apex of connective; without preapical lobe, with slight median lobe; apical portion directed ventrally; apex acute ( Fig. 15 ). Aedeagus ( Figs. 16–17 ) symmetrical; shaft, in lateral view, elongate, gently curved dorsally, with pair of apical processes directed anterad ( Fig. 17 ); dorsal area with process at anteapical portion and another one at apex, both dentiform ( Fig. 16 ). Anal tube ( Fig. 18 ) with distinct, median digitiform ventral process; basiventral portion with pair of small sclerotized projections directed to midline.

Female unknown.

Etymology. The new species name, felixi , is given in honor of Dr. Márcio E. Felix (Laboratório de Biodiversidade Entomológica, Instituto Oswaldo Cruz, Rio de Janeiro) in recognition of his contribution to the development of Brazilian entomology and friendship.

Type material. Holotype: male, “ PERU: Loreto Dept., \ Exploronapo Camp on R. [River] \ Sucusari nr. R. [River] Napo. \ 12-19-III-1988. \ J. E. Eger, coll.” ( NCSU).
