Keilbachia camptospina sp. n.

( Fig. 5 A, B)

Type locality: VIETNAM: Fan Si Pang Mts., Sa Pa.

Material examined. Holotype male. VIETNAM: Fan Si Pang Mts., Sa Pa, bank of creek, in damp vegetation, sweep-net, 25– 30.3.1997, leg. W. Mey ( SDEI).

Description. Male. Colour. Brown, legs yellowish, tarsi darker, wings fumose. Head. Missing in the holotype. Thorax. Anterior pronotum with 2 setae. Episternum 1 with 6 setae. Wings. Length 1.6 mm, width/ length 0.5. R1/R 0.95. c/ w 0.75. bM longer than r-m, r-m/bM 0.80, r-m and bM non-setose. Anal lobe strong. Legs. Fore tibia with a large subapical prolateral patch of dark setae. Length of fore basitarsomere/length of fore tibia 0.5. Tibial spurs longer than the apical width of tibiae. Abdomen. Sternite 8 with 8 setae. Hypopygium ( Fig. 5 A, B). Tegmen broader than its length, with lateral shoulders. Aedeagal apodeme rather long, aedeagal teeth ca. 15. Gonocoxite longer than gonostylus. Gonostylus evenly broad, with a short, flameshaped megaseta at the basal fourth, three additional narrow megasetae mesially, no apical tooth.

Female. Unknown.

Discussion. Keilbachia camptospina differs from all other species of the genus by having the gonostylus almost evenly broad, and by having a flame-shaped large megaseta as if formed by some united megasetae at the basal third of the gonostylus, and some additional elongated megasetae among the rather long mesial setosity of the gonostylus.
