Ta. Wheeler, Systematics of Mallochianamyia Santos-Neto (=Gayomyia Malloch), an unplaced genus of Neotropical acalyptrate flies (Diptera : Schizophora), IN SYST EVO, 31(2), 2000, pp. 209-224
Mallochianamyia Santos-Neto was proposed as a replacement name for Gayomyia
Malloch, 1933 (preoccupied by Gayomyia Banks, 1913), an unplaced genus of
acalyptrate Diptera from Chile and Argentina. The genus comprises 12 specie
s: M. cladostyla sp. n.; M. fenestrata sp. n.; M. flavitibia sp, n.; M. fur
cata sp. n.; M. gallina sp. n.; M. latigena sp. n.; M. magnipalpis sp. n.;
M. nigrohalterata (Malloch) comb. n.; M. penai sp. n.; M. serosa sp. n.; M.
truncata sp. n.; M, vexans sp. n. All new species are illustrated and a ke
y to species of Mallochianamyia is provided. The monophyly of the genus is
supported by three characters of the male and female genitalia. Mallochiana
myia is most closely related to the New World genera Paraleucopis Malloch a
nd Schizostomyia Malloch and an undescribed Australian genus. The group can
not be placed in any established family as currently defined, although ther
e are affinities to some families in the Asteioinea sensu J. F. McAlpine (1
989). Research on the morphology and relationships of genera related to Mal
lochianamyia is required to clarify the familial status of the group.
