Haromyia Runyon

Runyon, Justin B., 2015, Haromyia, a new genus of long-legged flies from Dominica (Diptera: Dolichopodidae), Zootaxa 3964 (5), pp. 589-595 : 590

Genus Haromyia Runyon , gen. nov.

Type species. Haromyia iviei , sp. nov. Male and female habitus ( Figs 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 1 , 3 ), and wing veins that evenly diverge from base to tip ( Fig. 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 R2+3, R4+5 and M1 nearly parallel; some Discopygiella Robinson which have fore tibia with a row of setae on distal half, R4+5 and M1 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.
