1. Molopopterus hastata Cao & Dietrich sp. nov.

(Figs 14, 26 i–l)

Description. Body lemon yellow (specimen preserved in ethanol before examination). Apical area of vertex, central area of pronotum and brochosome field of forewing slightly darkened; eyes grey; tip of anteclypeus dark brown; basal triangles of mesonotum brown, long. (Figs 26 i–l)

Male abdominal apodemes 2S (Fig. 14a) extended to middle of sternite IV. Anal tube (Fig. 14b) far surpassing hind margin of pygofer lobe.

Pygofer lobe (Fig. 14b) with distal angle somewhat blunt, with relatively dense fine setae and microsetae. Subgenital plate (Figs 14b, d) with about 3 macrosetae, marginal setae numerous, differentiated into three groups: basal group long and thick; middle group peg-like, from subbase to subapex; apical group rigid, relatively long and sparse. Style (Fig. 14e) with apical part robust, with transverse whorl-like sculptures; preapical lobe relatively small, with row of sensory setae above preapical lobe. Connective (Fig. 14f) with manubrium very wide. Aedeagal shaft (Figs 14g, h) thin and long, slightly curved, apex acuminate, with pair of thin processes subapically on dorsal margin directed basad and close to shaft; dorsal apodeme slightly expanded dorsad; preatrium and dorsal apodeme closely appressed, cleft narrow; gonopore subapical on dorsal side.

Measurement. Male length 2.90mm.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 01.vi–18.vii.2008, sweeping, coll. Sharkey.

Etymology. The new specific epithet is derived from Latin adjective “ hastatus ” which means “with spear”, referring to the spear-like apex of the aedeagal shaft.

Diagnosis. This species can be distinguished from the other species of the genus by the large group of peg-like setae medially on the subgenital plate, the apical whorl-like sculpture of the style and the spear-like apex of the aedeagal shaft.
