description: Gracilipona birama sp. nov.
(Figs 1, 2, 5A–B)
Diagnosis. Style (Fig. 1J) blade with ventral margin expanded at apical half; dorsal margin somewhat straight; apex directed dorsally; aedeagus (Figs 1K–L) shaft long with pair of processes, each elongate and extending slightly beyond apex of shaft; female sternite VII (Fig. 2A) with posterolateral angles subacute, weakly produced posterad.
Measurements (mm). Holotype male: total length 7.1. Paratypes: females (n = 2), 7.9–8.1.
Male terminalia. Sternite VIII (Fig. 1D) in ventral view, as wide as long; lateral margins straight and slightly tapering to apex; posterior margin rounded. Valve (Fig. 1E) in ventral view, 2x wider than long; posterior margin acute. Pygofer (Fig. 1F) in lateral view, 2x longer than high, ventral margin broadly rounded; apical portion triangular, tapering to acute apex. Subgenital plate (Fig. 1G), in ventral view, approximately 5.8x longer than wide; wider near apex than near base; lateral margins straight; apex rounded. Connective (Fig. 1H) in dorsal view, with arms as long as stem; stem expanded apically; dorsal keel developed. Style (Fig. 1I) in dorsal view, with outer lobe weakly developed, rounded; in lateral view (Fig. 1J), blade with ventral margin expanded at apical half; dorsal margin somewhat straight; apex thin, acute, directed dorsally. Aedeagus (Figs 1K–L) shaft long, with pair of processes arising lateroventrally and extending slightly beyond apex of shaft, curved anterad, weakly sclerotized; apex of shaft without processes. Other characteristics as in generic description.
Female terminalia. Sternite VII (Fig. 2A), in ventral view, 1.5x wider than long; posterolateral angles subacute, weakly produced posterad; posterior margin straight. First valvifer (Fig. 2C) 1.5x higher than wide. First valvula (Fig. 2C) 4.2x longer than high. Second valvula (Fig. 2F) 3.4x longer than high; apical portion (Fig. 2G) dorsal margin with approximately eight rounded denticles. Gonoplac (Fig. 2H) 2.8x longer than high.
Etymology. The specific epithet birama (noun in apposition), refers to the single pair of processes on the aedeagus.
Material examined. holotype male: Bahia: “ Encruzilhada - Bahia \ Brasil 980m XI/74 \ M. Alvarenga leg.” (DZUP). Paratypes: 2 ♀, same data of holotype (DZUP).
Remarks. Gracilipona birama sp. nov. is similar to G. tetrarama sp. nov. in color and morphology, but can be easily distinguished from the latter by the aedeagus with a single pair of processes and female sternite VII with lateral angles slightly produced posterad.
