03CBCC40FFFECD4D5DD9F8107C8843B6.taxon	diagnosis	Diagnosis. Ceratalictus can be distinguished from Augochlora, Augochlorella, and Pereirapis (the genera belonging to the Augochlora group) by the male and female epistomal sulcus forming an obtuse angle and body punctation relatively strong and coarse (as in Figs. 8, 18, 24), in combination with the following female characters: inner hind tibial spur tooth widely separated, and without basal expansion (see Eickwort 1969: 464, fig. 215); basitibial plate in female with anterior border poorly defined; and the following male characters: pale apical band on clypeus absent; ventral surface of male hind tibia with long erect setae, its length varying from 2 / 3 to equal the tibial width; and conspicuous parapenial lobe (Fig. 1).	en	Coelho, Beatriz W. T., Gonçalves, Rodrigo B. (2010): A taxonomic revision of the augochlorine bee genus Ceratalictus Moure (Hymenoptera, Apoidea). Zootaxa 2675: 1-25, DOI: 10.5281/zenodo.199190
03CBCC40FFFECD4D5DD9F8107C8843B6.taxon	description	Description. Total body length 5 – 9 mm. General color of body usually bright metallic green, sometimes with some bluish or reddish highlights. Body punctation strong and coarse. Female. Labral distal process narrowly triangular; basal elevation usually restricted to apical part. Preoccipital ridge carinate or lamellate. Lateral angle of pronotum obtuse or acute to strongly acute and projected. Inner hind tibial spur serrate, teeth widely separated, basal part not raised. Male. Apical margin of clypeus without pale apical band. Ven tr a l surface of hind tibia with a row of long erect setae, its length varying from two-thirds to equal to tibial width. Apical margin of S 8 with or without median process. Point of fusion between S 7 and S 8 before apodeme apex. Parapenial lobe present, relatively long; ventral process of gonostylus formed by two lobes; inner lobe of ventral process not divided.	en	Coelho, Beatriz W. T., Gonçalves, Rodrigo B.

03CBCC40FFFECD4D5DD9F8107C8843B6.taxon	discussion	Comments. Some characters deserve attention for being distinctively variant in some species of Ceratalictus in comparison to others: labrum with basal elevation transverse and occupying the whole sclerite occurs only in Ceratalictus clonius; the preoccipital ridge is strongly lamellate in C. stigon; the lateral angle of pronotum is obtuse in C. camargoi, C. clonius and C. psoraspis; only the male of Ceratalictus allostictus has setae on the ventral surface of the hind tibia longer than the diameter of tibia; and Ceratalictus argentinus, C. camargoi, and C. clonius have S 8 without median process on the apical margin. Finally, the obsolete anterior border of the basitibial plate cited by Eickwort (1969) and Engel (2000) can be found in some species of Augochlorella and is not considered here as a characteristic of Ceratalictus. Ten species of Ceratalictus are herein recognized; they can be identified using the key below. A phylogeny for the species of Ceratalictus will await for a more thorough elucidation of the relationships among genera of the Augochlora group. A phylogenetic study including several species of the group is currently being carried out by one of the authors (RBG), and the species recognized here form a monophyletic lineage.	en	Coelho, Beatriz W.

03CBCC40FFF7CD445DD9FDDD7FBA4658.taxon	discussion	Comments. Schrottky (1910) described Oxystoglossa thalia pauloensis based on a Ceratalictus female and an Augochlora male as already remarked by Moure (1950); here we recognize the validity of the lectotype designation for this name, as well as for Oxystoglossa theia, both made by Moure (1950). Moure (1999, 2007) considered the type-locality of Halictus psorops Vachal as Caçapava, state of Rio Grande do Sul, listed as Cansapava in the original species description, but here we evaluated the possibility that the type-locality could be Caçapava, state of São Paulo, consistent with the distribution of the remaining examined material. Additionally, the lectotype of Oxystoglossa theia Schrottky is designated and Augochlora lorenzinis Strand is synonymized with Augochlora clonia Brèthes. Among the material examined, we found variation in body size associated with slight differences in sculpturing of the mesoscutum and metapostnotum in both sexes. Larger individuals have more sinuous carinae accommodated on the lengthy metapostnotum and in males the mesoscutum and mesoscutellum usually have evident micro-reticulation. These variations could be found on specimens from the same location, while the male genitalia examined showed no variation, not supporting the hypothesis that the ensemble could include more than one species.	en	Coelho, Beatriz W.
