Eremohaplomydas Bequaert, 1959: 357 .

Type-species: Eremohaplomydas desertorum Bequaert, 1959 , by monotypy.

Diagnosis.

The genus can be delineated by the very small to minute proboscis, the costal vein terminating at the point where R1 joins the wing margin, the small body size of the majority of species, and the restricted distribution in the Namib Desert.

Distribution, biodiversity hotspots, phenology, and biology.

Known only from five disjunct localities in the northern and central Namib Desert in Namibia (Figs 56 - 57 ) to which the genus is endemic. A rarely collected genus known only from 18 specimens in museum collections from nine collecting events between 1951-2018 (Table 1 ). The genus is not known to occur in any currently recognized biodiversity hotspot. Adult flies are either active in early summer or mid-autumn to early winter (Table 2 ). Nothing is known of the biology.
