2.4. Diagnostic Notes The family Halictidae contains some of the most commonest bees and in many places halictids dominate other bees in number of species and number of specimens.

Halictidae is characterised by well developed hind leg and ventral metasoma scopae (except for cleptoparasitic species), one subantennal suture below each antenna, and arcuate basal vein, 3 submarginal cells, facial fovea absent. There are also a series of mouthparts characters.

There are 4 subfamilies Rophitinae, Nomiinae, Halictinae and Nomioidinae.

These subfamilies can be distinguished as follow:

- Rophitinae: Antennae arising below midlength of eyes; episternal groove present below scrobal groove; clypeus protuberant.

- Nomiinae: Antennae arising about midlength of eyes; episternal groove absent below scrobal groove; prepygidial fimbria not divided medially

- Halictinae: Antennae arising about midlength of eyes; episternal groove present below scrobal groove; prepygidial fimbria divided medially; apex of marginal cell pointed or miniutely truncate

- Nomioidinae: Antennae arising about midlength of eyes; episternal groove present below scrobal groove; prepygidial fimbria not divided medially; apex of marginal cell rounded or truncate
