TYPE MATERIAL

HOLOTYPE: 3, CHINA: Yunnan: Xiaomengyang , 850 m, 28-III-1957, F.J. Pu ; PARATYPE: 1♀, same locality as holotype, 810 m, 26-III-1957, D.H. Liu .

DIAGNOSIS

Paramyiolia yunnana can be distinguish from its congeners by the following combination of characteristics: 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 almost completely yellow brown; 3) male abdominal tergites 1-3 ( Fig. 7 ) and female tergites 1-4 yellow brown; 4) male abdominal tergite 4 and female abdominal tergite 5 with a pair of large dark brown specks; 5) male abdominal tergite 5 and female tergite 6 dark brown; 6) female head with 2 pairs of frontal setae. This species is very similar to Japanese P. cornuta , but can be separated by the above characters 3-5 (see Figs. 7 vs. 8).

Female head similar to that of male without frontal modification ( Fig. 24 ); frontal-head ratio 0.37, eye ratio 0.76 and genal-eye ratio 0.12; with only 2 pairs of frontal setae. Thorax predominantly yellow brown with dark brown to brown setae and yellow brown setulae; scutum heavily pruinose yellow brown; 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 2.1-2.6x as long as scutellum and apical seta 1.4-1.8x as long as scutellum; proepisternum densely covered with long yellow brown setulae; anepisternum with lower seta slightly shorter than upper seta; lower half of katepisternum dark brown; mediotergite shiny yellow brown. Legs yellow brown with yellow brown setae and setulae; fore femur strongly swollen with 6-7 posteroventral setae; midtibial spur 1.2- 1.5x as long as midtibia width. Wing ( Figs. 17, 18 ) 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 dark brown except for hyaline spot covering middle 1/3 of cell c; wing-thorax ratio 2.2-2.3, vein R 4+5 ratio 2.6-2.7, vein M ratio 0.55-0.59 and subcostal-costal ratio 0.42; R 4+5 with 8-15 tiny setulae between node and crossvein R-M.

Male abdomen ( Fig. 7 ) about as long as wide; tergites 1-3 yellow brown; tergite 4 with pair of large dark brown specks; tergite 5 dark brown; sternites 1-4 yellow brown; sternite 5 brown; epandrium ( Fig. 29 ) dark brown and surstylus yellow brown; lateral surstylus with both anterior and posterior lobes angular, truncate apically in lateral view; glans ( Fig. 34 ) 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 0.4x as long as sclerotized portion of glans.

Female abdomen with tergites 1-4 yellow brown; tergite 5 dark brown except narrow yellow brown mid-stripe; tergite 6 dark brown; sternites 1-5 yellow brown; sternite 6 brown; oviscape ( Figs. 35 and 37 ) dark brown with 2 long ventral marginal and 2 long dorsal marginal setae; eversible membrane ( Fig. 37 ) cylindrical, without any strong teeth; dorsal and ventral taeniae extending almost entire length of eversible membrane; aculeus ( Fig. 36 ) long, slender, with apex laterally flattened with serrated apex; 3 spherical spermathecae with transverse spinules ( Fig. 38 ); apical portion of spermathecal duct not swollen.
