Fig. 3 A–E.

Material studied. Holotype male. MALAYSIA, Selangor, University of Malaya Field Study Centre, 800 ft., Malaise in jungle, 24.2.– 14.3. 1997, H. Hippa, M. Jaschhof & B. Viklund (in NRMS). Paratypes. 2 males with same data as holotype (in NRMS).

Male. Colour. Almost unicolorous brown, maxillary palpus and legs paler brown than the other parts, abdomen slightly paler than thorax, wing hyaline brownish, haltere pale brown. Head. Eye bridge 3–4 facets wide. Face (prefrons) with 7–8 setae, which are widely spread. Clypeus with 0–1 setae. Maxillary palpus, Fig. 3 A: with 3 palpomeres. Palpomere 1 with 1–2 setae, the hyaline sensilla widely scattered on the dorsal surface, no sensory pit. Palpomere 2 with 5–6 setae. Palpomere 3 with 4–5 setae. Antennal flagellomere 4, Fig. 3 B. Thorax. Anterior pronotum with 2 setae. Episternum 1 with 2–4 setae. Wing similar to Fig. 5 A. Length 0.95 mm. Width/length 0.45–0.50. R1/R 0.50–0.60. c/ w 0.65. r-m and bM approximately equal in length, r-m/ bM 0.75–1.05. Legs. Apex of fore tibia, Fig. 3 C. Length of fore basitarsomere/length of fore tibia 0.45. Length of fore tibia/length of fore femur 1.15–1.20. Length of hind tibia/length of scutum+scutellum 1.44– 1.49. Abdomen. Sternite 8 with 6 setae in a transverse row on posterior part. Hypopygium Fig. 3 D, E: Gonostylus with the curved megaseta long, about two-thirds of the length of gonostylus, with three additional strong megasetae, one at the middle between the basal body of the curved megaseta and the apex, and two close-set subapically, no apical tooth. Tegmen with distinct but weak lateral shoulders.

Female unknown.

Discussion. Keilbachia camptonema is similar to K. ancylonema . For further discussion, see under the latter.
