Head: Black; face brown pruinose, facial swelling indistinct, mystax black with a few white setae laterally, more than 10 macrosetae; proboscis and palpi black, setae black; occiput brown pruinose laterally and grey pruinose medially, setae black. Antennae: scape black, black setae ventrally, apruinose; pedicel black, brown setae dorsally and ventrally, grey pruinose; postpedicel brown, grey pruinose; stylus brown, as long as postpedicel; apical 'seta-like' sensory element hyaline or brown. Thorax: Black, brown pruinose except for scutum and scutellum, anepisternum and katepisternum setae black; scutum black, sometimes red antero-laterally and antero-medially, predominantly apruinose, margins grey pruinose, surface covered with long white setae, white and brown setae on pruinose part; macrosetae: brown, 1 or 2 supra-alar setae; scutellum grey pruinose, discal scutellar and scutellar setae long, brown. Legs: dark brown; coxa brown pruinose; prothoracic and mesothoracic femora with erect black setae anteriorly and dorsally, metathoracic femora with erect black setae on all surfaces, clubbed and widest sub-distally; tibiae erect black setae on all surfaces, prothoracic tibiae with yellow cleaning setae in distal two-thirds ventrally, metathoracic tibiae with yellow setae disto-ventrally; tarsomeres with black setae, first metathoracic tarsomere with yellow setae postero-ventrally; empodium two-thirds to nearly length of claw. Wings: length = 7.3–10.0 mm; cell d densely covered with microtrichia; halter brown. Abdomen: Black; abdominal tergites brown pruinose anteriorly and grey pruinose posteriorly, abdominal tergite 2 in proximal half with long brown setae laterally, remaining abdominal tergites with short white setae, abdominal sternite 2 in proximal half apruinose and in distal half grey pruinose, abdominal sternites 3–4 grey pruinose, abdominal sternites 5–8 brown pruinose.
The species is distinguished from congeners by the overall black coloration, the predominantly black setae, and the densely arranged microtrichia in cell d.
