2. Projecta brevis Cao & Zhang sp. nov.

( Figs 6 , 24 u–x)

Description. Ground color pale yellow (specimens preserved in ethanol before examination), eyes grey. ( Figs 24 ux)

Male genital capsule ( Fig. 6b ) short, length subequal to width. Pygofer lobe ( Fig. 6b ) with distal extension relatively short; dorsal appendage ( Fig. 6b ) articulated to lobe, short and thick, with stick-like basal stem, bifurcated apically, dorsal branch slightly shorter and thinner than ventral one. Subgenital plate ( Figs 6b, d ) slightly surpassing pygofer lobe, apical part relatively broad in dorsal view, rounded apically in lateral view, with reduced stout setae subbasally. Style ( Figs 6e, f ) with very small second extension apically, apex only slightly widened, with sensory pits basally on middle part, preapical lobe short and broad. Connective ( Fig. 6g ) with manubrium broad and lateral arms thick. Aedeagal shaft ( Figs 6h, i ) with two pairs of thin processes distally forming X in caudal view, shaft with two small, triangular processes near middle: one on dorso-lateral margin and one on ventral margin, pair of asymmetrical tooth-like processes present basolaterally; preatrium short; gonopore dorsal.

Measurement. Male length 3.50–3.60mm.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 25.viii.2008, coll. Braet & Sharkey. Paratypes: 1♂, same data as holotype ; 2♂, same data except 23.viii.2008 ; 1♂, same data except 18.viii.2008 .

Etymology. The new specific epithet is derived from Latin adjective “ brevis ” which means short, referring to the short distal extension of the pygofer lobe.

Diagnosis. This species can be distinguished from the others by the relatively short distal extension of the pygofer lobe, wide manubrium of connective and X-shaped distal processes of the aedeagal shaft.
