Dufourea australis

(Michener, 1937)

Southwestern Shortface

Dufourea australis is a of sweat in the , first described by Michener in 1937. The species is commonly known as the Southwestern Shortface. It belongs to the Rophitinae, a group of bees characterized by their relatively short . Based on the specific epithet and , this species appears to be associated with southwestern regions of North America, though detailed ecological information remains limited in available sources.

Identification

As a member of the , Dufourea australis can be distinguished from other families by its relatively small size and typically metallic coloration. Within the Dufourea, identification to level requires examination of morphological features such as facial structure, , and . The "Southwestern Shortface" suggests a relatively short compared to related , a characteristic feature of the Rophitinae. Precise identification typically requires knowledge and microscopic examination.

Distribution

The specific epithet "australis" (southern) and "Southwestern Shortface" suggest this occurs in the southwestern United States, though precise geographic boundaries are not documented in available sources. The Dufourea has a Holarctic distribution, with North species primarily found in western regions.

Ecological Role

As a member of the , Dufourea australis likely functions as a in its range. Sweat in this family typically visit a variety of flowering plants for nectar and pollen, contributing to and functioning through services.

Other Dufourea speciesCongeneric share similar body plans and require detailed morphological examination for separation, particularly of facial structure and male .
Other Rophitinae (shortface bees)Members of this share the characteristic short ; separation relies on subtle morphological differences in , punctation patterns, and other fine structural features.
Other Halictidae (sweat bees)-level characters such as size, general body shape, and metallic coloration overlap broadly; and tribal characteristics must be examined for accurate placement.

Taxonomic Note

The was originally described by Charles Duncan Michener in 1937. Michener was a leading authority on , and his work on remains foundational. The specific epithet "australis" refers to the southern distribution relative to related species, not to Australia.
