Abstract

Ischiolepta lama and I. barberi from North America are described as new. They, together with four other species [I. crenata (Meigen), I. denticulata (Meigen), I. intermedia Han and Kim, and I. scabra (Spuler)], are recognized as a monophyletic group. A cladogram, a key, and illustrations of male genitalia for those species are provided.
