Diagnosis.

Head mostly yellowish, including face and frons; palpus yellowish-white; interfrontal seta long and strong; pedicel very long. Scutum with Y-shaped brown stripe extending to scutellum. Surstylus nearly “ triangular ” in shape. Hypandrium with two pairs of ventromedial setae.

Description.

Male. Body length 4.3–4.5 mm, Wing length 4.2–4.4 mm.

Head (Fig. 7 ) width 1.63 mm, mostly yellowish; palpus yellowish-white; 3 fronto-orbitals, setae small; interfrontal seta long and strong, some small setulae around the interfrontal seta; occiput yellowish with sparse small setae; gena more than 1 / 3 height of eye; antenna yellow, pedicel length 0.15 mm, twice length of first flagellomere, scape brown, arista sparsely short plumose; 1 ocellar seta and 1 postocellar seta, small; vibrissae very strong.

Thorax (Fig. 32 ) width 1.26 mm, mainly yellowish; scutum with brown Y-shaped stripe extending onto scutellum; scutellum yellowish on both sides, anepisternum with pale brown longitudinal stripes, katepisternum yellowish. Prescutellar seta absent; 1 postpronotal seta, 2 notopleural setae, 1 postsutural supra-alar seta, 1 + 2 dorsocentral setae, dark brown; intra-alar seta absent, 2 postalar setae, dark brown, posterior seta tiny; 2 lateral scutellar setae, 1 apical scutellar seta, strong and dark brown; 1 anepisternal seta, 1 katepisternal seta. Leg yellowish. Wing (Fig. 8 ) with light brown spots on distal 1 / 3, along veins R 2 + 3, the M 1 ratio 2.8; halter white.

Abdomen brown, setae and setulae dark brown. Male genitalia (Figs 9–12 ): epandrium 0.8 times as high as wide. Cerci small, the height and width almost equal, slightly separated distally, with small setae on the outer surface and one longer seta at apex. Surstylus nearly triangular in shape, 0.4 times the length of the genitalia, apex without spines. Hypandrium with 2 long setae at the apex. Distiphallus long, membranous.

Female. Unknown.

Distribution.

China (Shaanxi).

Etymology.

The specific name “ macrocera ” refers to the long antennae.

Remarks.

The new species is similar to H. extensicornis Frey , but can be separated by the long, strong vibrissae; the interfrontal setae are also very strong and nearly parallel. In H. extensicornis Frey , the vibrissae are small and the interfrontal setae are small and crossed ( Frey 1960).
