Manota bihamata sp. n. ( Figs 1C , 10 )

Description. Large species.

Male. Head. Antenna with fourth flagellomere 1.9 times as long as wide. Maxillary palpus with third palpomere bearing 2 curved sensilla; fourth palpomere with a small process apically.

Thorax. Anterior basalare bare. Laterotergite setose. Episternum 3 with ventral portion setose. Wing ( Fig. 1C ). Length 2.2–2.8 mm. Membrane with a few setae along posterior margin. Sc setose dorsally and ventrally. M1 proceeding proximally as a row of setae. CuA­fork complete. Presence of A1 indicated by a few setae in a line.

Terminalia ( Fig. 10 ). Sternite 9 distinct, large, rounded laterally, on posterior margin with a small, subrectangular lobe medially; with setae larger than those on gonocoxites. Ventro­lateral lobes of gonocoxites posteriorly bare and subrectangular, with very dense setae anteriorly. Disto­lateral lobes of gonocoxites large; each lobe bare inside ventrally and apically, with setae of various lengths elsewhere. Gonocoxites in position I+II with a large, very dense patch of numerous setae on lobe; in position III with 2 flat megasetae, one megaseta simple and whip­like apically, the other two­branched with one branch rounded and the other branch whip­like; in position IV with 2 large setae directed inwards. Gonostyli small, flat; with numerous long setae apically and some 5 setae dorso­subbasally. Parastylar lobes small; each with 2–3 long setae. Parameral apodemes widely spread. Tegmen evenly tapering to tip; margin of ventro­lateral lobes very distinct. Hypoproct tapering to tip; with long setae disto­laterally.

Diagnostic characters. This is the only species with only two, instead of three or more, curved sensilla on the third palpomere. Laterotergites are setose. The terminalia are distinct because of the outline of sternite 9 and gonocoxites.

Etymology. From Latin, bihamatus, with two hooks, referring to the two curved sensilla on the third palpomere.
