Dufourea pulchricornis

Members of Dufourea can be distinguished from other Halictidae by their relatively short faces, a trait reflected in the common name "short-faced bees." Dufourea pulchricornis specifically may be recognized by its notably ornate or well-developed antennae, as suggested by the species epithet. Detailed diagnostic features distinguishing this species from congeners would require examination of type specimens and original description.

Recorded from Middle America and North America. Specific locality data is sparse in available sources.

As a member of Halictidae, this species likely functions as a pollinator. The genus Dufourea is known for oligolectic behavior, where individual species specialize on pollen from a limited number of closely related host plant species, making them important specialists in plant-pollinator networks.

• Other Dufourea speciesCongeners share the short-faced morphology and oligolectic behavior; precise identification requires examination of antennae structure and other subtle morphological features described in Cockerell's original 1916 description.
• Other Rophitinae (short-faced bees)Subfamily members share facial shortening; Dufourea is distinguished within Rophitinae by specific genitalic and wing venation characters.
