(Figs 6 a–6c)

Psychomyia martynovi Hwang 1957: 385.

Description: Length of each forewing 2.9–3.1 mm (n = 10). Specimens in alcohol with eyes black, body dark brown except for lighter abdomen. Forewings with forks II, III, IV, and V present, crossveins r, s, m-cu and m nearly linear; hind wings with forks II, III, and V present, R 1 atrophied but discernable, R 2+3 ending at posterior margin (Figs 7g, 7h).

Male genitalia: Sternum IX in lateral view pentagonal (Fig. 6a). Tergum IX incompletely fused with preanal appendages, with distinct boundary between them when viewed laterally (Fig. 6a), each with one triangular basomesal tooth on lower margin in ventral view (Fig. 6c). Preanal appendages in lateral view somewhat rectangular (Fig. 6a), with upper margin concave and apicodorsal angle produced; in dorsal view (Fig. 6b) with base thick and distal ends truncate. Coxopodites small in lateral view (cox. in Fig. 6a), fused basally in ventral view (cox. in Fig. 6c). Harpagones each bifurcate (Figs 6a, 6c), in lateral view, lateral branch more or less clavate and mesal branch slightly tapered; in ventral view, mesal branch longer than lateral branch, spine-like, slightly curved; lateral branch short and straight. Phallic apparatus with phallotheca cylindrical and vertical in lateral view (Fig. 6a); endotheca with basal 1/3 vertical and distal 2/3 curved posterad, with two subapicolateral processes pointed cephalodorsad and curved mesad (Fig. 6b).

Materials examined: P. R. China, Zhe-jiang Province: 8 males, Hu-zhou City, An-ji County, Zhang-cun Town, Da-xi Temple of Long-wang-shan Scenic Area, 30°25′12″N, 119°24′36″E, alt. 326 m, 9 June 2018, leg. Y. Hu & Y. Wang (NJAU).

Distribution: China (Fu-jian and Zhe-jiang).

Remarks: This species belongs to Schmid’s P. pusilla Species Group. Its sternum IX and tergum IX are clearly separated in lateral views and tergum IX is incompletely fused with the preanal appendages but has triangular apical sclerites.
