Oecleopsis bifidus ( Tsaur, Hsu & Van Stalle, 1988)

Oliarus bifidus Tsaur, Hsu & Stalle, 1988: 52 .

Oecleopsis bifidus (Tsaur et al.) , Van Stalle, 1991: 25.

Description. Length (from apex of vertex to tip of fore wings): 3 6.9 mm, Ƥ 7.0– 7.1 mm.

Face yellowish brown, median and lateral carinae shiny yellow; vertex black with concolorous lateral carinae, median carinae absent, 1.6 times as long as broad, subapical carina V-shaped. Tegmina pale yellowish, hyaline, 3.2 times as long as broad, all veins yellowish with concolorous granules; stigma dark brown; RA unbranched, RP apically trifurcated, MA apically trifurcated, MP apically bifurcated, CuA bifurcated; Sc+R forked at same level as fork CuA1+CuA2; apex with eleven cells. Abdomen dark brown, borders yellowish. Legs with femora brown, tibiae and tarsi yellowish. Chaetotaxy of hind tarsomere 7/5.

Male genitalia. Ventromedian process small, in ventral view generally triangular in outline, broadest at base, its apex tapering and bluntly pointed. Genital styles in ventral view asymmetrical, right one stouter than left; with complex, transverse, denticulate apices curving apically forming hook-shaped, directed outwards; in lateral view with a thumb-shaped process subapically, and a round production at midlength of shaft. Aedeagus in total with three spines. Apical process of flagellum bifurcated, directed cephalad, subapical process curved dorsad; spine on right side at apex of aedeagus is very long, sinuate, about 3/4 length of periandrium.

Female genitalia. Caudal border of pregenital sternite shallowly excavated in middle, with two small convex processes submedially. Anal segment elliptic.

Material examined. CHINA: 1 Ƥ, Fujian, Shaowu, Dazhulan, 10/ 16-VII-1963 (I. Chou) ( NWAFU); 1 Ƥ, Fujian, Shaowu, Huangkeng, 8-VII-1963 (I. Chou) ( NWAFU).

Distribution. China (Fujian, Taiwan).

Remarks. Oecleopsis bifidus closely resembles O. sinicus and O. wuyiensis sp. nov. in the presence of a bifurcate apex of the flagellum. It differs from both in the presence of one subapical spine instead of two on the flagellum, and in the total number of spines on the aedeagus ( O. sinicus and O. wuyiensis sp. nov. have four spines each, O. bifidus has three). The spine on the right side at the apex of the aedeagus is very long in O. bifidus but very short in both O. sinicus and O. wuyiensis sp. nov. Oecleopsis bifidus differs from O. wuyiensis sp. nov. in the symmetrical rami of bifurcation (asymmetrical in O. wuyiensis sp. nov.). This species is recorded here for the first time from the Chinese mainland (Fujian Province).
