Type materials.
Holotype: China • 1♂; Hunan Province, Chenzhou City, Yizhang County, Mangshan National Forest Park; 24°58.80'N, 112°55.65'E; alt. 730 m; 1-ix-2020; light trap; W. Cao leg.; NJAU Tricho-20200901-0001. Paratypes: China • 10♂; same data as holotype; NJAU Tricho-20200901-0002 to Tricho-20200901-00011.
Diagnosis.
This species is similar to Psychomyia cuspidata Li, Qiu & Morse, 2021 from China ( Qiu and Morse 2021). However, P. mangshanensis sp. nov. can be easily distinguished by the following characteristics: (1) each superior appendage has a small triangular protrusion in the middle of the ventral margin in lateral view, which is missing in P. cuspidata ; (2) the basal process of each superior appendage is unbranched and with thick spine apically, whereas each superior appendage is two-branched, each branch has a thick spine apically in P. cuspidata ; and (3) the phallotheca is slightly wavy at midlength in lateral view but with an obtuse angle in P. cuspidata .
Description.
Male. Length of each forewing 2.8-3.1 mm (n = 10), holotype forewing 3.0 mm. Specimens in alcohol with compound eyes black; body dark brown dorsally and light brown ventrally. Forewings each with forks II-V present, and hind wings each with forks II and V present. Genitalia. Sternum IX subrectangular in ventral, dorsal, and lateral views (Fig. 2A, C View Figure 2 ). Tergite IX short and triangular in dorsal and lateral views (Fig. 2B, C View Figure 2 ). Division between tergite IX and segment X indiscernible in dorsal view (Fig. 2B View Figure 2 ) but distinguished by membrane in lateral view (Fig. 2C View Figure 2 ). Segment X parallel-sided, same width as apex of tergite IX, apically truncate in dorsal view, digitate in lateral view (Fig. 2C View Figure 2 ); with several long thick apical setae in dorsal and lateral views (Fig. 2B, C View Figure 2 ). Superior appendages well developed in lateral view, each tapering from base towards apex, divided into one narrow dorsomesal branch and one broad ventrolateral branch subapically; dorsomesal branch sclerotized and bare, acute in lateral view, ventrolateral branch setose about twice as wide as upper branch in lateral view (Fig. 2C View Figure 2 ); in ventral and dorsal views (Fig. 2A, B View Figure 2 ), dorsomesal branches of superior appendages angled mesad, ventrolateral branches curved slightly mesad; paired basal processes of superior appendages tubular, and slender, each with thick spine apically; in lateral view each with base directed dorsad, then recurved posteroventrad and evenly curved caudad (Fig. 2C View Figure 2 ); in ventral and dorsal views each slightly curving outwards (Fig. 2A, B View Figure 2 ). Phallobase slender, lanceolate in lateral view (Fig. 2C View Figure 2 ). Phallotheca tubular, with base produced caudad in lateral view (Fig. 2C View Figure 2 ), main portion sinuate, with apex hooked dorsad; phallotheca stick-like in ventral view (Fig. 2A View Figure 2 ), basoventral process plate-shaped, three times wider than main portion of phallotheca. Inferior appendages extending posterolaterad; coxopodites subtriangular, with their bases fused in ventral view (Fig. 2A View Figure 2 ); subrectangular, about 3 times as long as tall with middle of dorsal margin concave in lateral view (Fig. 2C View Figure 2 ); harpagones setose, arising from apices of coxopodites, fingerlike (Fig. 2A, C View Figure 2 ).
