Keilbachia adjuncta View in CoL sp. n.

( Fig. 2 View FIGURE 2 A, B)

Type locality: TAIWAN: Tainan Hasien, Kwantzeling.

Material studied: Holotype male. TAIWAN: Tainan Hasien, Kwantzeling, 250 m a.s.l., 6– 7.4.1965, leg. C.M. Yoshimoto ( BPBM).

Description. Male. Colour. The specimen is bleached, all pale brown. Head. Eye bridge 3 facets wide. Face (prefrons) with? 6 setae, clypeus with 1 seta. Maxillary palpus with three palpomeres. Palpomere 1 with 1 seta, palpomere 2 with 6 setae, palpomere 3 with 8 setae. Sensilla in patch or shallow pit. Antennal flagellomeres missing in the holotype. Thorax. Anterior pronotum with 1 seta. Episternum 1 with 4 setae. Wings and legs broken or missing in the holotype. Abdomen. Setae of sternite 8 not visible in the specimen studied. Hypopygium ( Fig. 2 View FIGURE 2 A, B). Tegmen with sharp lateral shoulders. Aedeagal apodeme moderate. Aedeagal teeth ca. 25. Gonocoxite elongated, longer than gonostylus. Gonostylus narrowed towards apex, slightly impressed mesially, with one apical megaseta and one slightly larger, straight and sharp mesial megaseta, the latter on a small basal body at about the apical third of gonostylus.

Female. Unknown.

Discussion. Keilbachia adjunta is not very similar to any other species of the genus. By having the mesial megasetae at the apical half of the gonostylus, and by having only one megaseta near the apex of the gonostylus, K. adjuncta resembles K. curvispina (Edwards) from Sumatra. In K. adjuncta , however, the mesial megaseta is short and straight, with a small basal body, and the apical megaseta is much thicker (see Fig. 2 View FIGURE 2 here and Fig. 3 View FIGURE 3 in Hippa & Vilkamaa (2007b)).
