Teleopsis currani ( Shillito, 1940)

( Figs 14–17 )

Cyrtodiopsis currani Shillito 1940: 159 .

Diagnosis: IVB on large protuberance, that is up to ¾ of the width of eye stalk in the middle, length of IVB 4– 5 times as long as eye stalk in the middle. OVB: 3–4 times the width of eye stalks in the middle (much longer than in other species), IAS not flattened (unlike in other three species). Scutellar spines 3–3.5 times as long as length of scutellum. Epandrium in dorsal view as wide as hypandrium. Only few hairs (8–10) at the base of hypandrium. Hypandrial bridge narrow.

Material examined: 2 males, 2 females, Thailand, Bangkok, 1-7 March 1971, [leg.] P. & P. Spangler (National Museum of Natural History, Washington D.C.)

Head: Yellow-brown, covered with minute whitish hairs up to ½ of the width of eye stalk in the middle. No facial teeth, edge rounded. OVB black, 3–4 times as long as width of eye stalk in the middle. IVB on large protuberance, that is up to ¾ of the width of eye stalk in the middle, length of IVB 4–5 times as long as eye stalk in the middle.

Thorax: Shiny yellow-brown, pollinosity only on the sides, posteriorly. IAS yellow-brown, not flattened. Scutellar spines 3–3.5 times as long as length of scutellum, darker towards tip.

Wing; Four dark bands (appearing as a dark wing with 3 white bands). The second dark band is continuous with the third, 3 white spots in the middle of the wing (border of the two dark bands).

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. Front femora similar to those of T. whitei , but shorter.

Praeabdomen: Tergites 1 and 2 yellow, otherwise brown, anterior part of tergite 2 brown, tergite 4 grayish pollinose. Hairs dispersed, short, the longest up to 1/3 of the length of first coxa.

Genitalia: The epandrium and the cerci have long, dispersed setae along their surface. There are two hairs (as long as T. whitei ) and 6–8 minute setae at the base of the hypandrium, the tip of the surstyli have numerous longer hairs, more dispersed than T. thaii and T. whitei ), i.e. not restricted to the tip. Surstyli slightly broadened in apical part ( Fig. 14 ). In lateral view the aedeagal apodeme is curved (as in T. thaii ), broadest in the middle ( Fig. 15 ). The parameres in ventral view have two long and 2–4 minute hairs ( Fig. 16 ). The hypandrium is connected to the aedeagal apodeme and there is no membranous part of the hypandrium, the hypandrial bridge is narrow ( Fig. 17 ). The genitalia in ventral view are as broad at the membranous part of the hypandrium as at the surstyli, i.e. the epandrium, comparable to T. whitei ( Fig. 17 ).
