Harten RMNH 02/, RMNH . Male. Holotype . Figs 38-45 . Measurements: body length = 5.3 mm; forewing length = 3,6 mm . Black. Reddishs-yellow: the whole antennae, mid clypeal disk, mandibles, semitransparent tegulae, semitransparent veins, all the legs but coxae, Tip of 7 th tergum and 6 th sternum. Tip of mandibles and pterostigma are brown. Head with very sparse p on frons and vertex with large impunctate areas around ocelli and stripe with mR and small p along cOc . No subapical denticle on mandible. Tyloids well expressed and prominent on all the flagellomeri. p on most of mesosoma like on head. N 1 disk with a distinct laminated carina along the fore border and a semitransparent impunctate apical stripe; lateral N 1 shagreened uppermost with a median transversal strong groove and wrinkled downwards. N 3 with only few small p . es 1 with denser smaller p and mR . Omaulus well distinct till signum.; ventral es 2 with a stripe of small p along the median suture. em 3 finely wrinkled uppermost and smooth ventrally. es 3 shagreened. Horizontal P shagreened outside areola, roughly transversally wrinkled inside; posterior (vertical) area irregularly corrugated; lateral areas with irregularly spaced strong wrinkles; well prominent lateral ribs of areola (mid one weaker). Inner hind coxa rounded. 1 st to 6 th terga and 2 nd to 5 th sterna with sparse p ; 7 th tergum and 6 th sternum deeply and more densely p ; 1 st sternum with large deep p at the base of the disk, apically with a strong transversal groove and buttressing ridges along it. N o t e. Paratypes do not show differences apart the smaller size of one of them (less than 5 mm ). In ALLEN’ s key (1975) it runs to the item of T. birganjae [ Holotype : / Nepal nr Birganj Lothar 450ft Malaise trap n° 30 Can. Nepal Exp./ / Holotype Tiphia birganjae HW Allen/ / Holotype Tiphia birganjae CNC N.15563/, CNC !] to which it looks very like. The latter shows different shape of the head in dorsal (more transversal) and frontal aspect (with a more depressed vertex), shape of clypeal disk (less prominent ventrally in frontal aspect and with a median notch), shape of N 1 disk in dorsal aspect (with stronger carina and buttressing ridges), a strong longitudinal carina on the inner surface of hind coxa, different and less prominent tubercle on 5 th sternum, different genitalia.
