TYPE MATERIAL

HOLOTYPE: 3, CHINA: Sichuan: Mt. Emei, Jiulaotong , 4-VIII-1957, F.X. Zhu.

DIAGNOSIS

Paramyiolia melanogaster can be distinguished from its congeners by the following combination of characteristics: 1) wing 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; 2) head and thorax including legs almost completely yellow brown; and 3) abdominal tergites 1-5 brown, distinctly darker than head and thorax (female unknown).

DESCRIPTION

Body ( Figs. 5 , 13, 14 ) with head and thorax yellow brown and abdomen brown; setae brown to dark brown and setulae mostly yellow brown; wing length 3.9 mm and thorax length 1.7 mm. Male head ( Fig. 21 ) largely 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 enlarged with 2 nd seta slightly shorter than and about 0.7x as thick as 1 st seta; posterior 2 frontal setae normal, less than 0.5x as long as 1 st seta; fronto-orbital plate associated with enlarged setae sharply elevated; frontal-head ratio 0.35, eye ratio 0.77 and genal-eye ratio 0.08; inner vertical seta 0.8x longest diameter of eye; outer vertical seta 0.6x as long as inner vertical seta; postocellar seta 0.4x as long as inner vertical seta; paravertical seta 0.5x as long as postocellar seta; ocellar triangle dark brown; ocellar seta 1.8x as long as ocellar triangle; antenna with scape and pedicel with dark brown setulae; parafacial very narrow, less than 0.2x as wide as flagellomere 1; facial ridge with short fine pale setulae; genal seta yellow brown; postgena moderately swollen with long yellow brown setulae; postocular setae extended 0.6x distance from upper eye margin to lower eye margin; supracervical setulae yellow brown; maxillary palp with brown apical and subapical setulae. Thorax entirely yellow brown with brown to dark brown setae and yellow brown setulae; scutum heavily pruinose; 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 2.2x as long as scutellum and apical seta 1.5x as long as scutellum; proepisternum densely covered with long yellow brown setulae; anepisternum with lower seta hair-like, about 0.7x as long as upper seta; mediotergite shiny yellow brown. Legs yellow brown; fore femur with 4 posteroventral setae; midtibial spur as long as midtibia width. Wing ( Fig. 13 ) hyaline with brown to yellow brown pattern; typical Anomoia - type pattern 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 DMCu 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; wing-thorax ratio 2.3, vein R 4+5 ratio 2.3, vein M ratio 0.58 and subcostal-costal ratio 0.52; R 4+5 with 10 tiny setulae between node and crossvein R-M.

Male abdomen ( Fig. 5 ) about as long as wide with tergites 1-5 brown and sternites 1-5 yellow brown; epandrium ( Fig.27 ) brown and surstylus yellow brown; lateral surstylus with both anterior and posterior lobes angular, truncate apically in lateral view; glans ( Fig. 32 ) 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 half as long as sclerotized portion of glans.

Female unknown.

DISTRIBUTION

China (Sichuan).

ETYMOLOGY

The specific epithet is a noun derived from the Greek ‘melanos’,meaning dark, and ‘gaster’, meaning belly, referring to the dark abdomen.
