Type locality.

PRC, Hu-bei Province: Jing-shan County, tributary of Da-fu-shui River, 50 km NW of Ying-cheng downtown, 31°16.74'N; 113°12.20'E, 90 m, 17 July 1990, collector JC Morse.

Type specimen.

Holotype. Male, in 75% ethanol, in cotton-stoppered microvial inside screwcap vial. Original label: “Hú běi, Jīn-shān-xiàn, 50 KM N.W. of Yīn-chéng, Trib. of Dà-fù-shǔi, 17 July 1990, 90 M elev., coll. Morse" " Metalype hubeiensis Holotype Li & Morse". Deposited in NJAU.

Paratypes. Same data as holotype, 5 males (4 in CUAC, 1 in NJAU). Original label: “Hú běi, Jīn-shān-xiàn, 50 KM N.W. of Yīn-chéng, Trib. of Dà-fù-shǔi, 17 July 1990, 90 M elev., coll. Morse" " Psychomyia sp. 7 鉴定者” [genus and species identity handwritten, Chinese characters = “Identifier”] " Metalype hubeiensis sp. n. paratype Li & Morse" [author names handwritten]. Also, a red paper tag without writing. Deposited in NJAU.

Diagnosis.

This species resembles Metalype truncata sp. n. The differences are as follows: (1) The apicomesal spur on each hind leg of Metalype hubeiensis is curved mesad and forked apically (Fig. 2E; the apicomesal spur on each hind leg of Metalype truncata is truncate apically, with a few lobes and an acute process, Fig. 4E); (2) in ventral view the coxopodites of Metalype hubeiensis are fused with each other basally (Fig. 2D; in ventral view the coxopodites are fused with each other for more than half of their length in Metalype truncata , Fig. 4D); (3) in lateral view the harpagones of Metalype hubeiensis are slightly expanded in the middle dorsally, each less than two times as wide as the basal part (Fig. 2A; in lateral view the harpagones of Metalype truncata are strongly expanded in the middle dorsally, each more than two times as wide as the basal part, Fig. 4A); and (4) in ventral view the harpagones of Metalype hubeiensis are hooked mesodorsad (Fig. 2D; in ventral view the harpagones of Metalype truncata are hooked mesad, Fig. 4D).

Description.

Male. Forewings each 3.4-3.9 mm (n = 5). Compound eyes black, body yellow. Apicomesal spur of each hind leg slightly curved mesad and forked apically.

Genitalia. In lateral view tergites IX+X wide basally, in dorsal view each half triangular and slightly narrowed laterally at two-thirds distance from base. In lateral view superior appendages digitate, wide basally and gradually narrowed from base to apex; in dorsal view central part slightly concave laterally, setose and with few stout and curved setae at apex; each with subapicomesal tooth short, about as long as wide. In ventral view sternite IX slightly expanded posteriorly. In lateral view coxopodites triangular, in ventral view subrectangular and fused with each other only basally. In lateral and ventral views, harpagones each weakly sclerotized and slightly expanded mesodorsad at mid length, in ventral view slightly curved mesad and strongly hooked mesad apically, with harpagonal hook stout and its mesal edge membranous, slightly sclerotized at apex. In lateral view phallus with two major curves, both curves greater than 90°, phallobase expanded, phallicata with pair of round subapicodorsal lobes and apical hook directed dorsad.

Female. Unknown.
