Distribution. Ceratina (Z.) capitosa only known from Mexico, in the Trans-Mexican Volcanic Belt, Pacific Lowlands and Sierra Madre del Sur biogeographic provinces (Morrone, 2019), with records from Jalisco, Michoacan, Morelos, Nayarit and Oaxaca. The distribution ranges from 0–2000 m in elevation.
Comments. Very similar in color and size to an undescribed species of Ceratina (Calloceratina) . For this reason, in some collections both species tend to be identified as C. capitosa ; however, they can be differentiated by the impunctate swollen areas on the frons of C. capitosa (diagnostic character for Zadontomerus ), spine-like projection in the base of hind tibia, and males with a tuft of dense hairs in the apex of T6.
