Diagnosis.

This species is unique among Psychomyia in that the coxopodites and the harpagones are completely fused and together form an S or Z shape in ventral view.

Description.

Male. Length of each forewing 3.6-3.8 mm (n = 3); holotype 3.7 mm. Specimens in alcohol with compound eyes black; body brown dorsally and light yellow ventrally. Forewings with forks II-V present, hind wings with forks II, III, and V present. Genitalia. Sternum IX nearly trapezoidal with anterior margin concave in ventral view (Fig. 1A View Figure 1 ); rounded, semicircular in lateral view (Fig. 1C View Figure 1 ). Tergite IX produced from dorsoposterior margin of sternum IX, membranous, somewhat bowl-shaped with apical margin sinuate and partially hidden under two superior appendages in dorsal view (Fig. 1B View Figure 1 ), tongue-shaped in lateral view (Fig. 1C View Figure 1 ). Superior appendages in dorsal view wide and long, each with larger mesobasal lobe and smaller subapical lobe both directed mesad and with apex truncate (Fig. 1B View Figure 1 ), twisted and clavate, each with inner side having cluster of spines subapically in ventral view (Fig. 1D View Figure 1 ); subrectangular in lateral view, each with blunt basodorsal process, angled posterodorsad at 2/3 length to truncate apex (Fig. 1C View Figure 1 ). Phallobase slender, basally directed anterad and evenly recurved posterad in lateral view (Fig. 1C View Figure 1 ). Phallotheca tubular, basally directed anterad, evenly recurved dorsad, caudad at midlength, and posteroventrad distally; apically depressed and trifurcate, acute mesally and with pair of long, subapical processes projecting caudad, then recurved dorsad and diverging anterolaterad (Fig. 1A-C View Figure 1 ). Inferior appendages in ventral view sigmoid (Fig. 1A View Figure 1 ), in lateral view strongly C-shaped (Fig. 1C View Figure 1 ); coxopodites elongate-rectangular in lateral view, heavily setose, and fused with slender harpago (Fig. 1C View Figure 1 ).

Etymology.

Latin noun in genitive singular. The new species is named after Shun, a leader of tribal alliances in ancient China, who is considered an important founder of the Chinese civilization. Moreover, the holotype and one of the paratypes were collected at Mt Shun-huang, the mountain named after Shun.
