Tachydromia Sabulosa
''Tachydromia'' is a genus of hybotid flies. It is widespread around the world, with species found essentially everywhere except the polar regions and some remote islands. They are not very diverse in East and Southeast Asia, or in AfricaShamshev, I. & Grootaert, P. 2010. The genus ''Tachydromia'' Meigen (Diptera: Hybotidae) from the Afrotropics. ''African Invertebrates'' 51 (1): 207-218. Description ''Tachydromia'' are minute, slender flies of shining jet-black color, that are almost devoid of hairs and bristles. The globular head bears large eyes with large facets. Three ocelli are present. The two-jointed antennae are short. The vertical, rigid proboscis is shorter than the head. The thorax is longer than broad. The slender legs bear microscopic hairs, but no bristles. The front femora are somewhat thickened. The males of some species have small spines on the middle femora or tibiae beneath. The wings are narrow, with the costa ending at the fourth vein and sometimes thi ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
