Figs 23 , 27 , 31 , 35 , 55-62 Note. Head with coronal suture extended to anterior margin (Fig. 23 ). Face yellow, eyes dark brown, thorax light brown (Figs 27 , 35 ). Crown with anterior margin white; pronotum with lateral margin white, remainder covered with a continuous large ocher patch extending to distal end of clavus of forewing (Figs 23 , 27 ); scutellum with apex orange (Fig. 27 ). Forewing light ocher with few light smoky patches in apical half, remaining part transparent except for white brochosome field. Male sternal abdominal apodemes extending to middle of 5th sternite (Fig. 55 ). Pygofer side tall and bilobate caudally, upper lobe with short setae terminally, lower lobe with several fine moderately long setae (Fig. 56 ). Subgenital plate elongate, triangular with single macroseta near base, a row of short rigid setae adjacent row of fine setae laterally and two indistinct peg-like setae apically (Fig. 58 ). Paramere with row of microsetae on outer margin and row of sensorial pits on inner margin (Fig. 59 ). Connective trapezoidal, with central ridge (Fig. 57 ). Aedeagal shaft with two apical processes, in ventral view left process slim, S-shaped, right process short and straight (Figs 60-62 ). Figures 37-54.

Specimens examined. Holotype : ♂ , China , Shaanxi Province , Yangling , ix.1983 , coll. Yalin Zhang. Paratypes : 10♂♂ , 4♀♀ , same data as holotype . Measurement. Male, 3.1-3.3 mm (including wing). Etymology. This new species is named for the two aedeagal processes, rather than three in other species. Remarks. This new species resembles Paracyba soosi Dworakowska, 1977 in coloration and male genitalia, but it differs from the latter in aedeagal shaft having two rather than three distal processes and processes of very different length.
