TYPE MATERIAL

HOLOTYPE: 3, CHINA: Sichuan: Mt. Emei, Qingyinge , 800-1000 m, 10-V-1957, Z.Y. Wang. Specimen in poor condition with lef wing missing and right wing damaged apically ( Figs. 11, 12 ).

DIAGNOSIS

Paramyiolia atrifasciata is the only species of the genus with 4 wide longitudinal stripes (lateral pair medially interrupted) on scutum ( Fig. 4 ). This species can be diagnosed as follows: 1) wing narrow, medially-interrupted C-band extending from DM-Cu to anterior apical wing margin and then along margin to slightly beyond apex of vein R 4+5; 2) scutum with 4 wide dark brown longitudinal stripes; and 3) abdominal tergites 3-5 dark brown (female unknown).

DESCRIPTION

Body ( Figs. 4 , 11, 12 ) yellow brown ground color except for dark brown scutal stripes and abdominal tergites; setae brown to dark brown and setulae mostly yellow brown; wing length approximately 4.5 mm (both wings broken in the only available specimen) and thorax length 1.8 mm. Male head ( Fig. 20 ) almost entirely yellow brown except dark brown ocellar triangle; frons sparsely covered with fine yellow brown setulae, deeply concave with highly modified frontal setae; anterior 2 frontal setae greatly enlarged with 2 nd seta slightly shorter and about 0.7x as thick as 1 st one; posterior 2 frontal setae normal, about half as long as 1 st seta; fronto-orbital plate associated with enlarged setae sharply elevated; frontal-head ratio 0.38, eye ratio 0.72 and genal-eye ratio 0.11; inner vertical seta broken off; outer vertical seta about as long as posterior-most frontal seta; postocellar seta slightly shorter than outer vertical seta; paravertical seta 0.6x as long as postocellar seta; ocellar triangle dark brown; ocellar seta about as long as ocellar triangle; antenna with aristal-antennal ratio 1.7; scape and pedicel with yellow brown setulae; arista short pubescent, entirely yellow brown; parafacial very narrow, about 0.2x as wide as flagellomere 1; facial ridge with short fine pale setulae; genal seta brown; postgena moderately swollen with long yellow brown setulae; postocular setae extended 0.7x distance from upper eye margin to lower eye margin; supracervical setulae yellow brown; maxillary palp with brown apical and subapical setulae.Thorax yellow brown ground color with brown setae and setulae; scutum heavily pruinose yellow brown with 4 wide dark brown longitudinal stripes, lateral stripes interrupted near transverse suture; dorsocentral seta about 0.4x distance from level of intra-alar seta to postsutural supra-alar seta; scutellum slightly convex, almost bare with few tiny marginal setulae, basal seta 2.4x as long as scutellum and apical seta 1.6x as long as scutellum; proepisternum densely covered with long yellow brown setulae; anepisternum with lower seta about half as long as upper seta; mediotergite shiny brown. Legs entirely yellow brown with brown to yellow brown setae and setulae; fore femur with 5 posteroventral setae; midtibial spur 1.2x as long as midtibia width. Wing ( Fig. 11 ) hyaline with brown to yellow brown pattern; typical Anomoia - type pattern with narrow, medially-interrupted C-band extending from DM-Cu to anterior apical wing margin and then along margin to slightly beyond apex of vein R 4+5; crossvein DM-Cu strongly oblique forming apically pointed cell dm; basal area enclosed by pterostigma, crossvein R-M, and basal half of cell DM-Cu almost entirely brown except for hyaline spot covering middle 1/3 of cell c; vein M ratio 0.40; R 4+5 with 10 tiny setulae between node and crossvein R-M.

Male abdomen ( Fig. 4 ) about as long as wide, tergite 1 yellow brown with pair of large sublateral brown specks; tergite 2 brown; tergites 3-5 subshiny dark brown; sternites 1-4 yellow brown; sternite 5 brown; epandrium ( Fig. 26 ) dark brown and surstylus brown; lateral surstylus with both anterior and posterior lobes angular, truncate apically in lateral view; glans ( Fig. 31 ) with distinct subapical lobe; acrophallus abruptly narrowed near apex, directed downward at about 75 degree angle; dorsal sclerite without extensive sculpture pattern found in most other genera of the subtribe Chetostomatina ; vesica relatively large, about 2/5 as long as sclerotized portion of glans.

Female unknown.

ETYMOLOGY

The specific epithet is an adjective derived from the Latin ‘ater’, meaning black, and ‘fasciata’, meaning striped, referring to the striped scutum.
