Lasiocnemus fascipennis Engel and Cuthbertson, 1939
Head: Black; face brown pruinose, facial swelling indistinct, mystax black with a few white setae laterally, 8–15 macrosetae; proboscis and palpi black, setae black; occiput grey pruinose, setae yellow and brown. Antennae: scape brown, black setae ventrally, apruinose; pedicel brown, brown setae dorsally and ventrally, grey pruinose; postpedicel brown, grey pruinose; stylus brown, slightly shorter than postpedicel; apical 'seta-like' sensory element brown. Thorax: Orange to brown, anepisternum and dorsal half of katepisternum and anepimeron grey pruinose, remaining parts brown pruinose, anepisternum setae black and katepisternum setae black or white; scutum black, red antero-laterally and antero-medially, predominantly apruinose, margins grey pruinose, surface covered with white setae, white and black setae on pruinose part; macrosetae: black, 1 notopleural seta, 1 supra-alar seta; scutellum grey pruinose, discal scutellar and scutellar setae long, black. Legs: brown; coxa brown pruinose; prothoracic and mesothoracic femora with erect black setae, metathoracic femora with erect black setae on all surfaces, clubbed and widest sub-distally; tibiae with erect black setae on all surfaces, metathoracic tibiae with these setae longest in proximal half ventrally, prothoracic tibiae with yellow cleaning setae in distal half ventrally, metathoracic tibiae with yellow setae in distal half ventrally, prothoracic and mesothoracic tibiae with yellow stripe dorsally; tarsomeres with black setae, first metathoracic tarsomere with yellow setae postero-ventrally; empodium two-thirds length of claw. Wings: length = 11.7–15.0 mm; cell d with only few microtrichia; halter brown. Abdomen: Black; abdominal tergites 2–5 brown pruinose anteriorly and grey pruinose posteriorly, abdominal tergites 6–8 bluish-grey pruinose, 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 brown pruinose, abdominal sternites 3–4 brown pruinose, abdominal sternites 5–8 black or bluish-grey pruinose.
The species is distinguished from congeners by its large body size, the yellow longitudinal stripe on the prothoracic tibiae, the few microtrichia in cell d, the wing coloration, and the presence of only short setae on the dorsal surface of the metathoracic tibiae.
