Psychomyia martynovi Hwang 1957 View in CoL

( Figs 6 View FIGURE 6 a–6c)

Psychomyia martynovi Hwang 1957: 385 View in CoL .

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 View FIGURE 7 ).

Male genitalia: Sternum IX in lateral view pentagonal ( Fig. 6a View FIGURE 6 ). Tergum IX incompletely fused with preanal appendages, with distinct boundary between them when viewed laterally ( Fig. 6a View FIGURE 6 ), each with one triangular basomesal tooth on lower margin in ventral view ( Fig. 6c View FIGURE 6 ). Preanal appendages in lateral view somewhat rectangular ( Fig. 6a View FIGURE 6 ), with upper margin concave and apicodorsal angle produced; in dorsal view ( Fig. 6b View FIGURE 6 ) with base thick and distal ends truncate. Coxopodites small in lateral view (cox. in Fig. 6a View FIGURE 6 ), fused basally in ventral view (cox. in Fig. 6c View FIGURE 6 ). Harpagones each bifurcate ( Figs 6a, 6c View FIGURE 6 ), 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 View FIGURE 6 ); endotheca with basal 1/3 vertical and distal 2/3 curved posterad, with two subapicolateral processes pointed cephalodorsad and curved mesad ( Fig. 6b View FIGURE 6 ).

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 GoogleMaps ( NJAU).

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