Bolitophila (Cliopisa) taihybrida sp. n.

( Figs 2 , 7 )

Holotype, male ( HNHM): Taiwan: Taichung Hsien, Anmashan Mts, 2090–2550 m, April 5–6,

2003, leg. M. Földvári, L. Papp, Ch.-M. Fu & H.-R. Tzuoo, No. 23, UV light traps.

Diagnostic characters. Vein R 4 ending in C. Anterior vein of posterior fork basally thin, but distinct. Stigma faint, grey. No conspicuous central spot on wing. Mesonotum yellow, with three dark brown longitudinal stripes. Gonostylus broad, tapered, apically with 2–3 short triangular denses, parameres short.

Description. Male. Body length 6.1 mm. General coloration brownish grey, legs yellowish brown, coxae yellow.

Head dark brown. Antennae with short hairs, about as long as the diameter of flagellomere. Scape and pedicel brownish yellow, about as long as wide, setose. Base of the first flagellomere yellowish. Mouthparts andpalpi brownish yellow.

Thorax. Mesonotum yellow, with three sharply marked dark brown longitudinal stripes. Scutellum brownish yellow, with several short apical setae. Lateral sclerites andmediotergite bare, dark brown. Halteres as long as thorax, brown, the stalk basally lighter.

Wings hyaline, membrane only with microtrichia. Wing length 5.0 mm. Costa slightly producedbeyondR 5. Vein R 4 curved (S-shaped), ending in C very close to the end of R 1. Stigma faint, grey. No conspicuous central spot. Posterior fork separatedfrom the vein above by a distinct crossvein. Anterior vein of posterior fork basally thin, but distinct. Posterior branch of posterior fork normal, not strongly curvedat tip.

Legs yellowish brown, coveredwith dark trichia andsetae. All coxae subequal in length, with several setae laterally. Femora cylindrical, narrow, covered with short black setae. Tibiae densely coveredwith dark trichia andseveral irregularly arrangedshort setae.

Abdomen dark brown, all tergites and sternites covered with dark setae.

Terminalia ( Figs 2 , 7 ) brown. Length of terminalia 0.38 mm. Ventral caudal margin of gonocoxites medially with a small incision. Gonostylus broad, tapered, apically with 2–3 short triangular denses. Aedeagus apicaly bifid, parameres short. Cerci short, rounded.

Female unknown.

Biology unknown.

Etymology. Derivedfrom Tai wan (type locality) and hybrida (relatedspecies).

Discussion. This species belongs to the B.hybrida (Meigen) group. The male terminalia are most similar to those of B.hybrida (for a comparision see Figs 7 and 8 ) and of B. nigrolineata Landrock, 1912 .
