Diagnosis.

This species resembles Metalype anaktujuh (Malicky, 1995b) ( Malicky 1995b, page 23, figures in the top right corner) but can be distinguished by the following characters: (1) In lateral view the harpagones of Metalype shexianensis are slightly narrower in the middle than at the ends (Fig. 3A) in contrast to the harpagones of Metalype anaktujuh ( Malicky 1995b, page 23, figure on the left); (2) In dorsal view the harpagones of Metalype shexianensis each bears two mesal processes, the anterior one is larger and truncate, the posterior one smaller and digitate (Fig. 3C),whereas the harpagones of Metalype anaktujuh each bears one truncate mesal process ( Malicky 1995b, page 23, figure on the right).

Description.

Male. Forewings each 3.8-3.9 mm (n = 2). Compound eyes black, body yellow. Apicomesal spur of each hind tibia curved laterad and twisted apically, with two small subapical processes.

Genitalia. In dorsal view tergites IX+X widely separated from each other, each half triangular, in lateral view nearly L-shaped. In lateral view superior appendages setose, each wide at base, narrower at mid length than at the ends and digitate at apical half; in dorsal view mid length expanded mesally and covered with short setae; subapicomesal teeth each about two times as long as wide. In ventral view sternite IX slightly expanded posteriorly. In lateral view coxopodites triangular, in ventral view ovate and fused with each other for over half of their length. In lateral view harpagones slightly shorter than superior appendages, weakly sclerotized dorsally and tapered to apex, setose ventrally; in ventral view slightly expanded basomesally, curved mesad and slightly sclerotized at apices, each with two mesal processes subapically, anterior one larger; in mesal view truncate with notch, posterior one small, digitate, bearing few setae at apex. Phallobase expanded, phallicata narrow at base and slightly expanded at mid length, curved caudad for about 90° subapically beyond pair of short subapicodorsal lobes and apical hook directed dorsad.

Female. Unknown.

Etymology.

An adjective in nominative singular from “She-xian,” a county in An-hui Province, China, referring to the type locality of this species.
