description: 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).
Description. Holotype male. Length 7.91 mm. Body dark olivaceous green with metallic tones.
Head. Mandibles with two teeth, dark brown. Labrum with yellow mark in the middle area. Eyes convergent below. Clypeus with inverted T-shaped yellow mark, filling almost all the surface; closely punctured and rugose surface. Lower paraocular area and supraclypeal area closely punctate, punctures adjacent to each other. Upper paraocular area and frons with punctures separated by a puncture diameter distance. Vertex densely punctate, with long and yellowish pubescence. Gena densely punctate, with long yellowish pubescence more conspicuous in the lower area. Preoccipital carina more evident than in female. Antennae dark brown. Head length 1.82 mm; head width 2.04 mm; lower interocular distance 1.11 mm; upper interocular distance 1.38 mm; ocellocular distance 0.47 mm.
Mesosoma. Pronotum with lateral carina reaching the coxae; dorsolateral angle with transverse carina; pronotal lobe with short pubescence on the edge. Mesepisternum densely punctate, punctures separated by a puncture diameter or less distance; hypoepimeral area with dense punctures on upper area, impunctate area towards the scrobal groove. Scutum, anterior area with yellowish pubescence as on vertex and with punctures separated by a distance up to twice puncture diameter; disc with punctures surrounding the parapsidal and anteromedial lines. Scutellum with close punctures, becoming sparser in the disc. Propodeal triangle striate. Propodeum, lateral area finely and densely punctate, with whitish plumose hairs. Tegula dark brown and impunctate. Smoked wings, pterostigma and venation brown. Length of forewing 5.47 mm. Scutum length 1.17 mm; scutum width 1.52 mm. Legs. Hind trochanter, ventral margin rounded with long and densely distributed pubescence. Hind femur medially dilated, basal half with yellowish, long and scattered plumose hairs (Fig. 22F).
Metasoma. T1 polished and impunctate, disc with small area finely and closely punctured. T2 and T3 with close punctation separated by a distance up to a puncture diameter, disc with sparse punctures. T4 with punctures separated by three times a puncture diameter; posterior margin with short scattered pubescence. T5 rugose. T6, medial area slightly projected and with hair tuft of copper pubescence. T7, posterior margin concave, forming a medial rounded projection (Fig. 23G). S6, as shown in Figure 24F. Genital capsule as shown in Figure 12.

Lower paraocular area densely punctate, punctures reaching the epistomal suture, separated by a distance of less than a puncture diameter. Upper paraocular area with punctures slightly more separated than lower area, distance among punctures up to twice the diameter of a puncture. Frons with impunctate swellings, surrounding area with punctures as on upper paraocular area. Vertex with long, yellowish pubescence. Gena wider than eye width in lateral view; area adjacent to eye polished and impunctate reaching 1/3 of the gena; upper and medial area with sparse punctures, becoming sparser below. Preoccipital margin carinate, becoming more evident in dorsal view. Antennae as in males.

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.
