Description. Male. Body length 1.12 mm. Frons dark brown. Supra-antennal setae present. Lower fronto-orbital setae absent. Lower interfrontal setae slightly shorter than upper interfrontal setae and the distance between each other equaled to that between upper interfrontal setae. First flagellomere dark brown, 0.16 mm long, with an aspect ratio of 2.1:1; arista 0.20 mm long, 1.26 times as long as that of first flagellomere. Palpus dark brown, with 6 short setae apically.

Thorax brown. Mid and hind legs dark brown, fore leg brown. Fore tibia with 13 small near-dorsal setulae, the uppermost being longer than the rest. Mid femur without sense-organ. Wing length 1.03 mm. Costal index 0.42, costal ratio 1.80:1, costal setulae length 0.03 mm. Rs with basisetula. Veins brown, except A 1 +CuA 2 whitish gray. Membrane hyaline. Halter brown.

Abdominal tergites dark brown. Terminalia ( Figs. 17A–C ) dark brown. Left surstylus ( Figs. 17A, D ) thin basally and broad apically, axe-shaped, with 3 inner teeth on basidorsal corner and 6 inner teeth on apical dorsal corner. Right surstylus ( Figs. 17B, E ) long banded, expanded apically and slightly bilobular, the upper-dorsal lobe with 3 inner teeth.

Female. Unknown.

Etymology. The specific epithet is derived from the Latin word securiclatus (axe-shaped), indicating the shape of left surstylus.

Specimens examined. Holotype, ♂, Yunnan, Menglun , 21-Apr-2007, Hongwei Chen.

Distribution. China (Yunnan).

Remarks. The species can be distinguished from all other species of the genus by the axe-shaped left surstylus and the bilobular right surstylus. In the keys of Disney (1990) and Michailovskaya (2000), the species will not run out to any species.
