[English summary]. The genus Baeodasymyia Clastrier and Raccurt, previously known only as adults from one extant and one fossil species, now includes four more extant species. The new species are described and named B. michaeli Borkent, n. sp., B. christopheri Borkent, n. sp., B. lydiae Borkent, n. sp., and B. gustavoi Borkent, n. sp. The larvae and pupae of B. michaeli and B. christopheri are also described and bionomic information provided for these and other species. Costa Rican species (n = 3) are all restricted to springs. Males and females of Baeodasymyia christopheri are strikingly sexually dimorphic in their thoracic pigmentation. A partially resolved cladogram suggests that the Dominican amber fossil species B. dominicana Szadziewski and Grogan is the sister group to all extant species, and that B. lydiae is the sister group to all remaining extant species (which are not further resolved). The presence of simple head capsule setae in larvae of Baeodasymyia indicates that this genus and its sister group Baeohelea Wirth and Blanton may be an early lineage within the Ceratopogonini. The Cretaceous genus Brachycretacea Szadziewski may be the sister group of Baeohelea + Baeodasymyia
