Ceratina (Zadontomerus) tepetlana Flórez-Gómez, Ayala & Hinojosa-Díaz new species

( Figures 11 , 12 , 22F , 23G , 24F , 27 )

Diagnosis: Medium sized bees, females from 7.0–9.0 mm, males from 6.8–8.0 mm in length; dark olivaceous green color, vertex in both sexes with conspicuous long and yellowish pubescence, more evident in males; smoked wings. Females with gena wider than eye width in lateral view, area adjacent to eye polished and impunctate; scutum disc in impunctate. Hind trochanter in males, with long and densely packed pubescence, hind femur medially dilated ( Fig. 22F ); and T7 with posterior margin concave, forming a medial rounded projection ( Fig. 23G ). Some females can be similar in size and wing color to those of C. ignara , but C. tepetlana can be distinguished by the long, conspicuous pubescence on the vertex, and the overall integument color, showing little contrast among head, mesosoma and metasoma (in C. ignara head and mesosomal color is bluish, contrasting the metasomal color).

Distribution: Ceratina (Z.) tepetlana is found from central Mexico to northern Guatemala, from 800 m to 2700 m in elevation. Its distribution corresponds to the Transmexican Volcanic Belt, Sierra Madre del Sur and Chiapas Highlands.

Etymology: The specific name refers to the Náhuatl word tépetl, which means mountain, indicating that this species can be found in mountain regions. It is an adjective in the nominative singular.
