Diagnosis. Medium to large in size: females from 7.0–9.0 mm and males from 6.5–8.0 mm in length. Bluish head and mesosoma, and dark green to olive green metasoma; males recognizable by the lower paraocular yellow marks; hind trochanter and ventral surface of basal half of hind femur with dense, long whitish hairs, as long as width of hind trochanter; hind femur medially dilated, but not forming an angle ( Fig. 22B ); T7 with concave lateral margins, distal margin truncate ( Fig. 23B ); females with lower paraocular area punctate, punctures separated by a distance up to a puncture diameter; disc of scutum predominantly impunctate, but some punctures along the anteromedial and parapsidal lines; metasoma twice as long as width; and both sexes with subhyaline to lightly smoked wings. Similar in color to C. indigovirens sp. n. (see below), but males can be easily recognized by the paraocular yellow marks and distal margin of T7 truncated.

Distribution. Ceratina (Z.) ignara ranges from Nayarit, Mexico to northern Panama. This species occurs from the sea level to 2200 m elevation and seems to be associated to tropical deciduous forests, tropical rainforests, and pine and cloud forests.

Comments: We propose Ceratina abdominalis as synonym of C. ignara based on the species description, where Smith (1907) mentioned the following characters in the male holotype: “head and thorax dark bluish green, abdomen coppery hue, apical plate truncate, almost twice as broad as long, corners well rounded. Small lateral face marks present”. These key characters are diagnostic to Ceratina ignara . Ceratina tehuacana and Ceratina parignara males show the same characters: yellow paraocular marks, head and mesosoma bluish and metasoma olive green, besides the shape of T7 and hind femur. These characters support that these species are synonymies.
