Diagnosis.

This species resembles Metalype hubeiensis sp. n. The differences are as detailed above for the latter species.

Description.

Male. Forewings each 3.9-4.5 mm (n = 10). Compound eyes black, body light brown. Apicomesal spur of each hind tibia truncate apically, with lobes on edge and central acute process.

Genitalia. In lateral view tergites IX+X slightly concave dorsally and acute at apex, in dorsal view each half round at apex. In dorsal view superior appendages setose, each with mesal setae short and apical setae thicker; in lateral view digitate, slightly curved caudad at mid length and gradually narrowed to blunt apex, in dorsal view subtriangular, each with subapicomesal tooth about 1.5 times as long as wide. In ventral view sternite IX slightly expanded posteriorly. In ventral view coxopodites ovate, fused for about half of their length, in lateral view triangular. In lateral view harpagones narrow at bases, gradually expanded to mid length, then narrowed abruptly, with dorsal surface of expanding area weakly sclerotized and slightly concave posteriorly; in ventral view harpagones hooked mesodorsad at apex, apex sclerotized and recurved anterad. Phallobase expanded, phallicata with small basoventral corner, then strongly sinuous and curved at mid length about 100°, with pair of wide subapicodorsal lobes, hooked about 170° dorsad apically.

Female. Unknown.
