Abstract:
t he genus Diglyphomorphomyia Girault is newly reported from the Neotropical region, with the majority of material and species from Costa r ica. It is represented by nine species in the region, and all are new species described here: D. albiclava, D. albicoxa, D. carinifer, D. costulata, D. cristata, D. metallica, D. parva, D. pedunculata, D. pilosa. An identification key for the species is included. t he Neotropical species of this genus differ in one morphological feature from o ld World species, but share several important characters with the type species of Diglyphomorphomyia from Australia. t he biology of Diglyphomorphomyia species is unknown, but they are probably parasitoids of concealed lepidopteran larvae
