Nomioides species have a yellow translucent posterior part of T2, revealing the basal part of T3 underneath. Males have an apical process on their sternite 8.
Ceylalictus species have a black or brown T2 posterior margin masking the basal part of T3. Males have no apical process on their sternite 8.
  • Nomioides - Halictus & Lasioglossum
Nomioides species are very small with a marginal cell rounded to truncated. Females have no furrow on T5.
Halictus & Lasioglossum species are much larger with a marginal cell pointed. Females have a furrow on T5.
