Description. External morphological characters as in generic description.

Male terminalia. Sternite VIII (Fig. 6) partially covering subgenital plates; in ventral view, trapezoidal; 1.5 times wider than long; posterolateral angles rounded; posterior margin slightly excavated. Valve (Fig. 7), in ventral view, three times wider than long; integument thickened only on anterior margin; posterior margin deeply excavated medially. Pygofer (Fig. 8), in lateral view, elongate and narrow; about three times longer than maximum height; apex tapered, subacute; macrosetae dispersed only at apex and posterior margin. Subgenital plate, in lateral view (Fig. 8), not produced posteriorly as far as pygofer apex; in ventral view (Fig. 9), 3.3 times longer than wide, apical half wider than base; ventral surface with small setae near external margin; lateral margins divergent toward apex; external margin slightly rounded; internal margin excavated at mid-length; apex abruptly subacute. Connective (Fig. 10) Y-shaped; approximately one-third as long as style; stalk longer than wide. Style, in dorsal view (Fig. 10), with outer lobe well-developed with microsetae; in lateral view (Fig. 11), apical half with long microsetae; ventral margin serrated pre-apically; apex curved dorsally and rounded, with elongate and acute apical process directed mesad. Aedeagus (Figs 12, 13) with preatrium reduced; dorsal apodeme developed dorsally, flattened and rounded; shaft elongated and flattened dorsoventrally, with pair of short apical processes, bent ventrally.

Female terminalia. Sternite VII (Fig. 18) 1.7 times wider than long; posterolateral angles subacute and produced; posterior margin deeply excavated each side of a rounded median lobe. Internal sternite VIII membranous. Pygofer (Fig. 19) elongate and narrow; about 2.8 times longer than maximum height; apex truncate; macrosetae dispersed near apex and microsetae near ventral margin. First valvifer (Fig. 20) 1.5 times higher than long; anterior angle rounded; anterior margin slightly excavated; dorsal and posterior margins straight. First valvula (Fig. 20) slightly curved dorsally; about 7.5 times longer than high; with approximately same height along entire length; apex (Fig. 21) with dorsal sculptured area strigate, ventroapical margin areolate; apex acute. Second valvula (Fig. 22) approximately four times longer than maximum height; apical portion (Fig. 23) dorsal and ventroapical margins with minute and uniform denticles; apex tapered and acute. Third valvula (Fig. 19) 3.5 times longer than high; ventral margin with only short setae; apex acute.

Etymology. The new species epithet is derived from the Latin word “ pulchra ” meaning beautiful.
