( Figures 5 , 6 , 21A , 22C , 23 C-D, 24C, 26)

Ceratina nautlana Cockerell T. D. A., 1897: 160 (syntype: USNM: ♀, ♂ 3352. Mexico, Veracruz, San Rafael, Río Nautla) Ceratina bakeri Smith, H. S., 1907 (holotype: USNM ♂ 63513. Mexico, Guerrero, Acapulco ), n. syn.

Ceratina nigriventris Friese, H., 1916 (holotype: Museum für Naturkunde Berlin: ♂, ♀. Costa Rica, San José), n. syn.

Diagnosis: Small to medium in size: females from 4.0– 6.2 mm and males from 3.5–4.5 mm in length. Both sexes with yellow markings on the pronotal lobe; body dark green to dark bluish, with metallic tints; subhyaline wings; females upper paraocular area and frons, around the impunctate swellings, with sparse punctures, surface mostly polished; supraclypeal area impunctate or with sparse punctures. Similar to C. kopili n. sp. but can be recognized by the presence of a longitudinal yellow mark on the foretibia; females with disc of the scutum almost entirely impunctate ( Fig. 21A ); males with yellow marks on the lower paraocular area, sometimes diluted or absent; T7 with two laminar projections forming a middle notch, which can be less evident in some individuals ( Fig. 23 C-D); mandibles sometimes with yellow marks on the inner margin; hind femur with slight rounded dilation ( Fig. 22C ).

Distribution. Cerataina (Z.) nautlana has a wide geographic range, from Nayarit, Mexico to Antioquia, Colombia, ranging from sea level to ~ 2000 m elevation. It is associated with tropical forests, especially dry forests.

Comments. Along its distributional range this species shows color variation, from dark olive green to dark bluish. In some females the yellow marks on the foretibia are less evident. Some males from Nicaragua, Costa Rica, Panama, Colombia and the Pacific Coast of Mexico, do not have paraocular yellow marks, besides, there is variation in the shape of the apex of T7. This is possibly a species complex; we could not find discrete and constant characters to delimit more than one species, but additional studies using methods such as DNA barcoding may reveal cryptic diversity ( Gibbs 2009). Morphology of the genital capsules is constant across the geographic range. We propose Ceratina bakeri and Ceratina nigriventris as synonymies of Ceratina nautlana based on the observation of type material, male holotype of C. bakeri presents the characteristic longitudinal yellow mark on the foretibia, shape of hind femur and T7 of C. nautlana . Ceratina nigriventris male and female types have a longitudinal yellow mark on the foretibia. Female has the scutum disc impunctate, and male share with C. nautlana the shape of T7 and foretibia.
