Lasiocnemus londti Dikow, 2007
Head: Black; face grey pruinose, facial swelling indistinct, mystax black, sometimes with lateral setae yellow or even entirely yellow, 4–6 macrosetae; proboscis and palpi black, setae black; occiput grey pruinose, medio-dorsally brown pruinose, setae light brown to white. Antennae: scape brown, brown setae ventrally, apruinose; pedicel light brown to red, brown setae dorsally and ventrally, grey pruinose; postpedicel light brown, grey pruinose; stylus brown, slightly longer than postpedicel; apical 'seta-like' sensory element brown. Thorax: Brown to black, anepisternum and dorsal half of katepisternum and anepimeron grey pruinose, remaining parts brown pruinose, anepisternum setae and katepisternum setae white; scutum black, brown antero-laterally, entirely pruinose, predominantly grey pruinose, median longitudinal stripe originating anteriorly but not reaching posterior margin and two lateral longitudinal stripes originating subanteriorly and reaching posterior margin brown pruinose, surface covered with long black setae, often setae on grey pruinose area white; macrosetae: black, 1 notopleural seta, 1 supra-alar seta; scutellum grey pruinose, discal scutellar and scutellar setae long, brown or white. Legs: brown to dark brown; coxa brown pruinose; prothoracic and mesothoracic femora with erect black setae on all surfaces, metathoracic femora with erect black setae posteriorly, proximal two-thirds and distal one-quarter with white erect setae anteriorly, dorsally, and ventrally, band of entirely black erect setae sub-distally, clubbed and widest sub-distally; prothoracic and mesothoracic tibiae with erect black and white setae on all surfaces, metathoracic tibiae with white setae in proximal and distal thirds, black setae medially, prothoracic tibiae with yellow cleaning setae in distal two-thirds ventrally, metathoracic tibiae with yellow setae at distal margin ventrally; tarsomeres with black setae, first metathoracic tarsomere with yellow setae postero-ventrally; empodium half length of claw. Wings: length = 6.5–8.5 mm; cell d with very few microtrichia, especially in specimens from Kenya and Tanzania anterior half covered with microtrichia; halter brown. Abdomen: Black; abdominal tergites brown pruinose anteriorly and grey pruinose posteriorly, abdominal tergite 2 in proximal half with long yellow setae laterally, remaining abdominal tergites with short yellow or brown setae, abdominal sternites brown and grey pruinose.
The species is distinguished from congeners by the entirely pruinose scutum, the few microtrichia in the discal cell, and the white and black setae on the metathoracic femora and tibiae (white setae proximally and distally, black setae medially).
