The mid tibia has 1 dorsal and 1 ventral seta very long; the hind femur is slightly inflated in the male and slightly less so in the female. Distinguished from  Hybos phahompokensis  sp. nov.,  H. zhejiangensisYang & Yangand  H. shamshevi  sp. nov.primarily by differences of male and female terminalia.   Description.Body length 4.0– 4.5 mm. Almost identical with  Hybos phahompokensis  sp. nov.in both sexes but with different terminalia. Maleterminalia ( Figs 59–65). Left surstylus ( Figs 62–64) with inwardly curved, broad, distally flattened (but pointed in some views) dorsal process at the base of which is a short bulbous swelling. Right surstylus ( Fig. 65) moderately long, slightly incurved, bluntly pointed; without internally directed pointed triangular process basally. Hypandrium ( Fig. 60) rather elongate, narrowing apically with small elongate black triangular subapical processes; extreme apex strongly bent inwardly with minute, sharp, beak-like, apical process ( Fig. 61). Femaleterminalia ( Figs 66, 67). Tergite 8 with posterior margin deeply and smoothly concave. Sternite 8 elongate, 4 pairs of stout yellowish bristles directed downwards; short blunt process posteroventrally bearing numerous short, stout setae. Tergite 10 and sternite 10 very weakly sclerotized.   Comment.  Hybos inthanonensis  sp. nov.is very similar to  H. zhejiangensisYang & Yang, 1995,  H. shamshevi  sp. nov.and especially  H. phahompokensis  sp. nov.from which it can only be distinguished by morphology of the terminalia. Although the male terminalia exhibit remarkable similarities to those of  H. phahompokensis  sp. nov.the female terminalia have a very distinctive pvprocess on sternite 8.  Hybos inthanonensis  sp. nov.is recorded only from moist hill evergreen forest above 2,200 mon the mountain Doi Inthanon (Thanon Thongchai Range), northern Thailand( Fig. 253). Adults have been recorded in April and May ( Fig. 291) corresponding with the start of the wet season. 3698642488 2007-04-29 2007-05-06 2007-04-29 Malaise trap QSBG Y.
