genitalic

However, the genitalic structure of the holotype reveals slight differences compared to A. flavata.

Apsilocephalidae are close relatives (sister group) of Therevidae distinguishable by genitalic characters.

While traditionally considered a single species, barcode and genitalic analyses indicate that five or more species are probably involved in the complex.

Males have diverse sclerotized genitalic structures.

The Sonoran carpenter bee is distinguished from other species of the genus by differences in their genitalic morphology.

Roy R. Snelling predicts that X. sonorina will eventually be described as a synonym of X. varipuncta, however, the two species are presently distinguished by alleged differences in their genitalic morphology.

They can mainly be distinguished by genitalic differences in males, as the shape of the upper forceps or the evolution of lamellae from the fusion of bristles, but also for the leghth of hairs and bristles on the facial gibbosity.
