FOUR NEW AND UNUSUAL CHIRONOMIDAE (DIPTERA)

Abstract One new genus, Phycoidella, and four new species, Cricotopus macraei, Cricotopus flannagani, Phycoidella dentolatens, and Lenziella cruscula are described in all stages. The genus Lenziella Kieff. is emended. The described species, three Orthocladiinae and one Tanytarsini, have many aberrant, but not necessarily apomorphic features.
