Teleopsis whitei ( Curran, 1936)

( Figs 6–9 )

Diopsis whitei Curran 1936: 1 .

Diagnosis: IVB length up to 4.5 times as long as width of eye stalk in the middle. Thorax pollinose on posterior part, scutellar spines up to 3.5 times as long as length of scutellum. Epandrium in dorsal view as wide as hypandrium. Only few hairs (4–6) at the base of hypandrium. Hypandrial bridge broad, slightly narrowed at the middle.

Material examined: 5 males, 5 females taken from a laboratory culture housed at University College, London in July, 2006. This culture was founded from individuals caught in Ulu Gombak, Malaysia by Andrew Pomiankowski and Samuel Cotton in April 2005. The dried, double–mounted specimens are deposited in the Hungarian Natural History Museum, Budapest.

Head: Yellow-brown, covered with white hairs up to as long as width of eye-stalk in the middle. No facial teeth, face rounded at the edges. OVB black, slightly larger than width of eye-stalk in the middle. IVB on a small tubercle in the middle of eye stalk. IVB length up to 4.5 times as long as width of eye-stalk in the middle.

Thorax: Shiny yellow-brown on sides, anepimeron and posterior half of meron grayish pollinose. Scutum somewhat golden pollinose. IAS yellow, flattened dorsoventrally. Scutellar spines up to 3.5 times as long as length of scutellum.

Wing: Hyaline with 4 bands; proximal and distal bands are narrow and pale, 2nd band includes distal part of cell dm and R-M cross vein; 3rd band attaches to the 2nd along vein M.

Legs: Covered with hairs (shorter than those on the head). Coxae and femora yellow, tibiae and tarsi brown, front femora with rows of peg-like black tubercles.

Praeabdomen: Covered with hairs (shorter than those on the head). Tergites generally brown with yellow stripe on front half of T3 and sides of T1–3.

Genitalia: The epandrium and the cerci have long, dispersed setae along their surface. There are two hairs (longer than T. thaii ) and two minute setae at the base of the hypandrium, the tip of the surstyli have numerous short, distinct hairs, surstyli broadened at tip ( Fig. 6 ). In lateral view the aedeagal apodeme is curved (more than that of T. thaii ), broad at distal one third ( Fig. 7 ). The parameres in ventral view have two long and 4–6 minute hairs ( Fig. 8 ). The hypandrium is connected to the aedeagal apodeme and the membranous tip of the hypandrium (hypandrial bridge) is slightly divided into two parts anteriorly ( Fig. 9 ). The genitalia in ventral view are as broad at the membranous part of the hypandrium as at the surstyli, i.e. the epandrium ( Fig. 9 ).
