Musbrnoia angusta sp. nov. ( Figs 2a–d , 7 ) Description. Ground color ( Figs 2a–d ) testaceous, eyes grey, basal triangles of mesonotum black. Face with pair of small brownish-pale marks on anteclypeus. Fore wing transparent in apical 2/3. Pygofer side ( Fig. 7 b) long, narrowing caudad, with few rigid setae at dorso-caudal angle and one near ventrocaudal margin; dorsal appendage ( Fig. 7 c) gun-shaped, tapering apically, with broad, hooked handle extended from central part of ventral margin. Subgenital plate ( Fig. 7 e) with about 4 macrosetae near central margin and 3 peglike microsetae beneath subapical angulate projection. Style ( Fig. 7 f) sinuated in dorsal view, preapical lobe central. Connective ( Fig. 7 g) Y-shaped, lateral arms relatively broad. Aedeagal shaft ( Figs 7 h, i) tubular, compressed, single ventral process lamellate, slightly curved dorsad, shorter than shaft, ventral edge serrated; gonopore central. Measurement. Male length 4.4mm . FIGURE 7.

Material examined. Holotype : ♂, THAILAND , Phetchabun, Thung Salaeng Luang, NP Pine forest Gang wang nam yen, 16°35.789'N , 100°52.286'E , 769m , Malaise trap, 16–22. xii. 2006 , coll. Pongpitak and Sathit. Deposition. QSBG , Chiang Mai, Thailand . Diagnosis. Similar to M. lata sp. nov. , but pygofer side much longer with dorso-caudal angle narrow, and ventral process of aedeagus slim. Etymology. This new specific epithet is derived from the Latin word “ angustus ”, meaning narrow, referring to the relatively slim ventral process of aedeagal shaft.
