Type materials.
Holotype: China • 1♂; Fujian Province, Longyan City, Wuping County, Liangyeshan National Nature Reserve; 25°12.37'N, 117°11.03'E; alt. 750 m; 2-vii-2021; light trap; J. Zhu & W. Han leg.; NJAU Tricho-20210702-0001. Paratype: China • 1♂; same data as holotype; NJAU Tricho-20210702-0002.
Diagnosis.
This species is similar to Psychomyia shuni sp. nov. from China in having the superior appendages with dense spines mesally and in having well-developed subapical processes on the phallic apparatus. However, P. capricornis sp. nov. can be easily distinguished by the long, slender processes arising from the bases of the coxopodites, which are absent in P. shuni .
Description.
Male. Length of each forewing 3.5-3.7 mm (n = 2), holotype forewing 3.7 mm. Specimens in alcohol with compound eyes black, body brown dorsally, 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 dorsal view (Fig. 3B View Figure 3 ); rounded anteriorly, subelliptical in lateral view (Fig. 3C View Figure 3 ); with posterior margin narrowly notched mesally in ventral view (Fig. 3A View Figure 3 ). Tergite IX membranous with irregular posterior margin in dorsal view (Fig. 3B View Figure 3 ); hemispherical in lateral view (Fig. 3C View Figure 3 ). Superior appendages elongate-triangular in dorsal view (Fig. 3B View Figure 3 ); subrectangular in lateral view (Fig. 3C View Figure 3 ), anterior margin of each produced into apodeme, distal half setose, upper margin sinuate and lower margin straight, with apex oblique and rounded; each with base produced dorsomesad (Fig. 3B, C View Figure 3 ); mesal ridge cambered and subtriangular with ventral side covered with spines (Fig. 3B, D View Figure 3 ); elliptical in lateral view (Fig. 3C View Figure 3 ); and with subapex produced into blunt process mesally in ventral and dorsal views (Fig. 3B, D View Figure 3 ). Phallobase hemispherical in lateral view (Fig. 3C View Figure 3 ). Phallotheca directed dorsad basally, then curved dorsocaudad about 90°, subapically with dorsal margins produced into pair of slender and apically acute subapical processes (or “horns”), and distal end hooked dorsad (Fig. 3C View Figure 3 ); in ventral and dorsal views subapical processes curved outwards at middle (Fig. 3A View Figure 3 ). Coxopodites setose, each with subapical harpago produced inwards as triangular process in ventral view (Fig. 3A View Figure 3 ); inconspicuous in lateral view (Fig. 3C View Figure 3 ). Long, slender, bare process arising from base of each coxopodite, sinuate, apically acute in ventral and lateral views (Fig. 3A, C View Figure 3 ); extending far beyond apex of coxopodite and harpago, and with distal ends of opposing processes crossed above phallotheca in ventral and dorsal views (Fig. 3A, B View Figure 3 ).
Etymology.
The Latin feminine adjective Psychomyia capricornis means “goat’s horn", referring to the shape of the pair of subapical processes on the phallic apparatus.
