Treatment

Gracilipona birama View in CoL sp. nov.

( Figs 1 View FIGURE 1 , 2 View FIGURE 2 , 5A–B View FIGURE 5 )

Diagnosis. Style ( Fig. 1J View FIGURE 1 ) blade with ventral margin expanded at apical half; dorsal margin somewhat straight; apex directed dorsally; aedeagus ( Figs 1K–L View FIGURE 1 ) shaft long with pair of processes, each elongate and extending slightly beyond apex of shaft; female sternite VII ( Fig. 2A View FIGURE 2 ) 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 View FIGURE 1 ) in ventral view, as wide as long; lateral margins straight and slightly tapering to apex; posterior margin rounded. Valve ( Fig. 1E View FIGURE 1 ) in ventral view, 2x wider than long; posterior margin acute. Pygofer ( Fig. 1F View FIGURE 1 ) in lateral view, 2x longer than high, ventral margin broadly rounded; apical portion triangular, tapering to acute apex. Subgenital plate ( Fig. 1G View FIGURE 1 ), in ventral view, approximately 5.8x longer than wide; wider near apex than near base; lateral margins straight; apex rounded. Connective ( Fig. 1H View FIGURE 1 ) in dorsal view, with arms as long as stem; stem expanded apically; dorsal keel developed. Style ( Fig. 1I View FIGURE 1 ) in dorsal view, with outer lobe weakly developed, rounded; in lateral view ( Fig. 1J View FIGURE 1 ), blade with ventral margin expanded at apical half; dorsal margin somewhat straight; apex thin, acute, directed dorsally. Aedeagus ( Figs 1K–L View FIGURE 1 ) 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 View FIGURE 2 ), in ventral view, 1.5x wider than long; posterolateral angles subacute, weakly produced posterad; posterior margin straight. First valvifer ( Fig. 2C View FIGURE 2 ) 1.5x higher than wide. First valvula ( Fig. 2C View FIGURE 2 ) 4.2x longer than high. Second valvula ( Fig. 2F View FIGURE 2 ) 3.4x longer than high; apical portion ( Fig. 2G View FIGURE 2 ) dorsal margin with approximately eight rounded denticles. Gonoplac ( Fig. 2H View FIGURE 2 ) 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.
