Teleopsis sp. n.: Carr et al. 2006b, Carr 2007 Teleopsis sp. n. 1: Papp et al. 2006

Diagnosis: Inner vertical bristle (IVB) only 3–4 times as long as the width of eye stalks in the middle. Thorax shiny in general, scutellar spines up to 5 times as long as scutellum (longest among this four species group). Epandrium in dorsal view narrower than hypandrium. Only few hairs (8–10) at the base of hypandrium. Hypandrial bridge broad, widest at the middle.

Type material: Holotype, male (Hungarian Natural History Museum, Budapest). Paratypes 4 males, 5 females (Hungarian Natural History Museum, Budapest), 5 males, 5 females (Natural History Museum, London). All type specimens (dried, double mounted, excellent condition) taken from a laboratory culture housed at University College, London in July 2006. Parent specimens were collected at Doi Suthep National Park, Chiang Mai, Thailand. Label data: over and along a brook, above and below a small waterfall, Nov 9, 2004, leg. L. Papp & M. Földvári, No. 27.

Head: Yellowish red, with minute, whitish hairs, up to 1.5 times the width of eye stalks in the middle. No facial teeth, edges rounded. Outer vertical bristle (OVB) narrow, 1.5 times the width of eye stalks in the middle. IVB on a small tubercle black, 3–4 times the width of eye stalks in the middle.

Thorax: Generally shiny, Intra–alar spine (IAS) yellow, slightly curved posteriorly in dorsal view, flattened dorsoventrally. Scutellar spine up to 5 times longer than scutellum, yellow–brown, with hairs on the spine as long as the diameter of the spine.

Wing: Four dark bands, proximal band pale, only a dark spot visible above cell cup.

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; mid femora slightly swollen in posterior view.

Praeabdomen: Tergites 1 and 2 completely yellow, first half of tergite 3 yellow, otherwise brown. Tergites 1 and 2 with brown spots dorsally in the middle; tergite 3 with grey pollinose spots on the sides. Hairs on the abdomen (as well as all over the body) moderately long, up to ½ of the length of the first coxa

Genitalia: The epandrium and the cerci have long, dispersed setae along their surface. There are two hairs and four minute setae at the base of the hypandrium, the tip of the surstyli have numerous short, distinct hairs ( Fig. 2 ). In lateral view the aedeagal apodeme is slightly curved, longest among the four species discussed here, not broadening towards tip ( Fig. 3 ). The parameres in ventral view have two long and two minute hairs ( Fig. 4 ). The hypandrium is connected to the aedeagal apodeme and the membranous tip of the hypandrium (hypandrial bridge) is continuous, not divided into two lobes anteriorly ( Fig. 5 ). The genitalia in ventral view are broader at the membranous part of the hypandrium than at the surstyli, i.e. the epandrium ( Fig. 4 ).

Etymology: The name refers to Thailand where the type locality can be found.
