3. Projecta depressa Cao & Zhang sp. nov.

( Figs 7 , 25 a–d)

Description. Ground color pale yellow (specimens preserved in ethanol before examination), eyes grey. ( Figs 25 a– d)

Male genital capsule ( Fig. 7b ) spherical. Pygofer lobe ( Figs 7b, d ) with distal extension relatively long and broad, pointed or bifurcated apically; dorsal appendage ( Figs 7b, c ) articulated to lobe, thin and long, curved ventrad, with stick-like basal stem. Subgenital plate ( Figs 7b, f ) terminating well short of apex of pygofer lobe, apical part narrow in dorsal view, obliquely truncate apically in lateral view. Style ( Figs 7g, h ) apex moderately attenuated and evenly curved, with sensory pits basally on middle part, preapical lobe short and broad. Connective ( Fig. 7i ) with manubrium narrow. Aedeagal shaft ( Figs 7j, k ) depressed, lateral margins curved ventrad, apex denticulate on dorsal margin, with pair of long, thin processes apically, extended ventrad then strongly curved dorsad; dorsal apodeme tapered in lateral view; preatrium elongate, apex widened and blunt, directed caudad.

Measurement. Male length 4.10mm.

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: 2♂, same data as holotype except 18.viii.2008 ; 1♂, same data except 29.viii.2008 .

Etymology. The new specific epithet is derived from Latin adjective “ depressus ” which means flattened dorsoventrally, referring to the depressed aedeagal shaft.

Diagnosis. This species is similar to P. draciformis sp. nov., but the pygofer extension is wider, the pygofer dorsal appendage is longer and curved ventrad, the aedeagal shaft is wider and has only one pair of processes, and the preatrium is much longer.
