The Halictine Bees of Sri Lanka and the Vicinity. III. Sudila (Hymenoptera: Halictidae) Part 2

Abstract

The halictine genus Sudila (Cameron, 1898), mainly characterized by the male gigantism, is reinterpreted as a subgenus of Lasioglossum Curtis with 6 species: bidentatum, alphenum, aulacophorum, knndiense (all Sri Lanka, males of 2 last species are first described), jacobsoni (Java), and paralphenum sp. nov. (S. India), mainly characterized by singular metepisternal tubercle (absent in paralphenum) and well dentate male inner tibia1 spur (jacobsoni, male unknown), all confined to the mountains of S. Asia. This part 1 gives features common to these species and taxonomic and chorologic notes on each species.
