Metadrinomyia proclinata Shima View in CoL ( Figs. 1 View FIGURE 1. A – B I–J, 2I –J, 2L, 3D–F)

Metadrinomyia proclinata Shima, 1980: 261 View in CoL ; Herting & Dely-Draskovits, 1993: 164 (in Palaearctic Catalog).

Diagnosis. Metadrinomyia proclinata can be distinguished from the congeners by the wider flagellomere 1 (about 2.7x as long as wide) and the tarsal claws shorter than 5th tarsomere. At a glance, this species resembles M. flavifrons but it can be distinguished by the above characteristics plus the following male genitalic structure: at least apical 1/4 of cerci narrowed and finger-like vs. narrow apical portion much shorter (cf. Figs. 3B and 3E).

Redescription. Male. Body almost entirely dark brown with whitish gray pruinosity; wing length 5.0mm; thorax length 2.7mm. Head ( Figs. 2I –J View FIGURE 2. A – J ) with frons-head ratio 0.36, eye ratio 0.65, gena-eye ratio 0.10, arista– antenna ratio 0.95; inner vertical seta, 0.82x as long as longest diameter of eye; outer vertical seta 0.53x as long as inner vertical seta; ocellar seta 0.69x as long as inner vertical seta; postocellar seta 0.30x as long as inner vertical seta; paravertical seta short but clearly discernible, 0.28x as long as inner vertical setae; frontoorbital plate with whitish gray pruinosity, without any setulae; 7–8 frontal setae, above level of aristal sockets; 2 proclinate orbital setae, posterior one 0.66x as long as inner vertical seta, anterior one 0.88x as long as posterior one; 1 reclinate orbital seta about half as long as inner vertical seta; frontal vitta black, bare; pedicel, scape and flagellomere 1 dark brown with whitish gray pruinosity; aristomere 1 as long as wide; aristomere 2 twice as long as wide; basal 1/3 of aristomere 3 thickened; flagellomere 1 slender, about 2.66x as long as wide; parafacial with dense whitish gray pruinosity, bare, 0.66x as wide as flagellomere 1; postgena moderately swollen with relatively long whitish yellow setulae, mixed with several black setulae anteriorly; palpus dark brown with dark brown setulae. Thorax ( Figs. 1 View FIGURE 1. A – B I–J) almost entirely dark brown with whitish gray pruinosity; postpronotum with 3 setae arranged in straight line; scutellum with 3 distinct scutellar setae, subapical seta 3.0x as long as scutellum length, lateral seta as long as subapical seta, basal seta 0.53x as long as subapical seta, discal seta hair-like, apical seta not recognizable; anepisternum with 1 small setae anterodorsally; posterior spiracle with reddish brown hairy lappet; prosternum bare. Legs ( Fig. 1 View FIGURE 1. A – B J) entirely blackish brown with dark brown setae and setulae; midtibia with 2 anterodorsal and 2 posterior setae; tarsal claws, 0.77x as long as 5th tarsomere. Wing ( Figs. 1 View FIGURE 1. A – B I–J) hyaline with slightly dark brown tinge; wing-thorax ratio 1.9, vein R4+5 ratio 3.7, vein M ratio 1.2, subcosta-costa ratio 0.56; fork of R2+3 and R4+5 dorsally and ventrally with 1 tiny seta each; tegula blackish brown; basicosta yellow to orange brown. Abdomen dark brown in ground color with whitish gray pruinosity. Genitalia (Figs. 3D–E) yellow brown to dark brown; sternite 5 (Fig. 3F) with V-shaped median cleft 0.5x as deep as sternite length; epandrium anterolaterally with setae; cerci with strong basal setulae, with apical 1/4 narrowed to form finger-like process.

Female. unknown.
