Mitchell (1962) has recently redescribed both sexes of Ceratina calcarata and has provided a key. The males are readily distinguished among the eastern species by the large femoral tooth which is obtusely angled 115°, fringed ventrally with long, curling setae (fig. 9b), and the width at the tooth is slightly more than 0.5 length. The width of the broad apical plate (fig. 12i) may be more than 3.0 times the length. These structural characters, plus the medium size and bluish or bluish green color will separate C. calcarata from C. dupla which has virtually no femoral tooth and from C. strenua which averages smaller, is more greenish, and has a narrow apical plate.

The females of C. calcarata and C. dupla are separated with certainty only by rearing with the associated males. Attempts have been made to provide key characters (Sandhouse, 1935; Mitchell, 1962), but I have been unable to confirm the distinctions. After long experience in Indiana, Chandler (in litt.) observed that females of C. calcarata lack a spot on the labrum and have the clypeal mark absent to triangular. Over half of the females of C. dupla have a spot on the labrum and a bell-shaped clypeal mark which may be reduced but not absent. Other characters, according to Chandler, are unreliable. In this study, the distribution map (fig. 16) is based only on males.

Robertson did not designate a holotype in his description of C. calcarata and no specimen in his collection bears an unequivocal type label. Dr. W. E. LaBerge has kindly provided 35 males from the Charles Robertson collection at the Illinois Natural History Survey, Urbana. Among these, I have selected a specimen as the lectotype which bears a top label “13707,” a lower label “Charles Robertson Collection,” and my red lectotype label. The number refers to an entry in Robertson’s record book: “1893:13707 Ceratina tejonensis male April 11 on Ranunculus fascicularis.” The specimen is deposited in the Illinois Natural History Survey. It corresponds to Mitchell’s description (1962), but has a broader apical plate. The lectotype differs from fig. 12i given here in having the median teeth separate to their bases.
