A revised diagnosis of Palaeoglaesum Wagner (Diptera, Psychodidae, Bruchomyiinae) with description of two new species from Cretaceous Myanmar amber

摘要

The diagnosis of Palaeoglaesum Wagner is revised to add details of the head, wing and male genitalia. A critical discussion of character states observed in this genus is provided to clarify details pertinent to accurate species delimitation. Two new species, P. carsteni n. sp. and P. wagneri n. sp., from Cretaceous Myanmar amber are described and illustrated. The holotype of P. velteni (Wagner) was acquired from a private collection to be deposited in a museum collection; further details of this species are given based on examination of an additional male specimen.
