Surimyia, a new genus of Microdontinae, with notes on Paragodon Thompson, 1969 (Diptera, Syrphidae)

Surimyia, a new genus of Microdontinae (Diptera: Syrphidae) is described, based on specimens from Suriname. Surimyia is the only known genus of Syrphidae in which the katatergum (ventral part of lateral postnotal sclerite of mesonotum) lacks microtrichia. Within Microdontinae, the genus is unique in the absence of pilosity on the postpronotum. It is also remarkable in the presence of strong, black setae on thorax and abdomen, a character rarely found in Syrphidae. The genus is superficially similar in external morphology and colouration to Paragodon Thompson, 1969, but clearly different in the characters mentioned above, as well as in the structure of the male genitalia. Two species are assigned to Surimyia: S. minutula (van Doesburg, 1966) and S. rolanderi spec. nov. Generic morphology is discussed. Differences between the species are described and illustrated.
