Haromyia Runyon

gen. nov.

Genus Haromyia Runyon  , gen. nov.

Type species. Haromyia iviei  , sp. nov. Male and female habitus ( Figs 1View FIGURE 1, 2).

Diagnosis. Haromyia  can be distinguished from other Dolichopodidae  by the combination of small body size (1.0– 1.5 mm), bulging clypeus with six large setae ( Figs 1View FIGURE 1, 3View FIGURE 3), and wing veins that evenly diverge from base to tip ( Fig. 4View FIGURE 4). Haromyia  keys to Achalcus Loew  and Australachalcus Pollet  or Enlinia  and Harmstonia  in Nearctic and Neotropical keys ( Robinson 1964; Robinson & Vockeroth 1981; Bickel 2009). On Dominica, Haromyia  could be confused with Enlinia  or Harmstonia  to which it keys in Robinson (1975). The presence of six large setae on a bulging clypeus separates Haromyia  from all of these. The only other New World dolichopodids I know of with clypeal setae are female Harmstonia  , which lack acrostichal setae and have a dorsal arista; the coastal species Nanomyina barbata (Aldrich)  , which has a dorsal arista, yellow setae, and wing veins R 2 + 3, R 4 + 5 and M 1 nearly parallel; some Discopygiella Robinson  which have fore tibia with a row of setae on distal half, R 4 + 5 and M 1 nearly parallel, and hypopygium enlarged, disc-like and laterally flattened; and some Nearctic Gymnopternus Loew  which have setae on the dorsal surface of antennal scape.

Etymology. Haromyia  is named to honor the botanist and entomologist, Harold E. Robinson, in recognition of his many contributions to the study of Dolichopodidae  , especially describing the Dominica fauna and for his unequaled work on the micro-dolichopodids.
