Mexalictus

Mexalictus species can be distinguished from other Halictinae by genitalic and other morphological features described in Eickwort's original 1978 revision. The genus belongs to the subtribe Halictina, and species-level identification requires examination of male genitalia and other microscopic characters. Metallic coloration alone is insufficient for distinguishing Mexalictus from related genera such as Lasioglossum or Halictus.

The genus is endemic to Mexico and adjacent regions of Central America, with species distributions centered in Mexican highlands and various ecological zones across the country.

As members of Halictidae, Mexalictus species function as pollinators within their native range. The genus contributes to pollen and nectar collection in Mexican ecosystems, though specific plant associations remain poorly documented.

• LasioglossumBoth genera belong to Halictinae and share metallic coloration and small body size; Mexalictus is distinguished by unique male genitalic morphology and geographic restriction to Mexico
• HalictusOverlaps in general halictine morphology; Mexalictus differs in genitalic structure and lacks the strong banding patterns common in many Halictus species
• SphecodesSome Sphecodes species share metallic coloration, but Mexalictus is not cleptoparasitic and shows distinct wing venation and body proportions
