Blagorrhina blagoderovi sp. n.

Material studied. Holotype male: MALAYSIA, Pahang, Genting Highlands, Awana, Malaise trap near the cable car route, about 3300 feet, 10–22. III.1997, M. Jaschhof, H. Hippa & B. Viklund ( NRM). Paratypes: same data as holotype, 6 ♂ ( NRM); MALAYSIA, Awana, lower cable­car station, primary forest, net+exhaustor, 6.III.1997, M. Jaschhof, 1 ♂ ( NRM).

MALE. Head. Fig. 2 C. Length of antenna about 1.5 times height of head, flagellomere 4, Fig. 4 A. Colour of head light brown, darker brown at vertex and dorsal part of occiput, colour of antenna similar to ground­colour of head, without any colour pattern, setae of head dark.

Thorax. Fig. 7 A. Suture between anepisternum and katepisternum complete or abbreviated so that it does not reach anterior margin of sclerites. Anterior pronotum with 3–5 setae. Episternum 1 with 7–11 setae. Laterotergite with 2–4 setae. Colour pale brown, darker brown mediodorsally, colour of setae dark. Wing. Fig. 8 E. Wing length 1.25–1.45 mm. Colour tinged with brown, more strongly so anteriorly. Haltere brown, basal half of stem pale. Legs. Fig. 7 B and C. Length of spur on tibia 2 two­and­a­half times apical width of tibia. Basitarsomere 1/tibia 1 0.66–0.69. Basitarsomere 3 three times as broad as basitarsus 1. Legs concolourous with thorax, leg 1 paler towards apical parts

Abdomen. Colour as on thorax but slightly paler. Hypopygium, Fig. 11 A and B.

FEMALE. Unknown.

Etymology. The species epithet is dedicated to Dr. Vladimir Blagoderov, now Department of Entomology, Iowa State University, Ames, to acknowledge his contribution to the study of Lygistorrhinidae .
