Morphologically close genera and how to distinguish them:
  • Lasioglossum - Halictus & Thrincohalictus
Lasioglossum species have submarginal vein 3 and recurrent vein 2 less visible than submarginal vein 1. Hairs bands on the abdomen are at the basal part of the segments.
Halictus & Thrincohalictus species have submarginal vein 3 and recurrent vein 2 of similar strength than submarginal vein 1. Hairs bands on the abdomen are at the apex of the segments (not always clearly visible in Seladonia and Vestitohalictus).
  • Lasioglossum - Ceylalictus & Nomioides
Lasioglossum species have a marginal cell pointed. Females have a furrow on T5.
Ceylalictus & Nomioides species are very small with a marginal cell rounded to truncated. Females have no furrow on T5.
  • Lasioglossum - Andrena
Lasioglossum species have a strongly curved basal vein.
Andrena species have a basal vein straight or at most slightly curved.
  • Lasioglossum - Apidae (e.g. Ceratina), Megachilidae (e.g. Osmia, Heriades)
Lasioglossum have short mouthparts (short-tongue morphology).
Apidae and Megachilidae have long mouthparts (long-tongue morphology)
General comments on Lasioglossum species identification
Wing venation, head shape, legs, scutum, propodeum and first abdominal tergites carry identification criteria. The legs and wings need to be slightly spread out to reveal these characters.
Male identification often requires sternites and genitalia extraction, in addition to antennae and tibial spurs.
Sorry, but the species identification tool is not yet available for Lasioglossum.
