Augochlora (Oxystoglossella) eucnemis ( Vachal, 1911)

( Figure 13B )

Halictus eucnemis Vachal, 1911 , holotype female (MNHP) from Brazil, Pernambuco. Examined through photographs.

Diagnosis

Females of this species have the basal elevation of the labrum orbicular and both sexes have the portion of mesepisternum anterior to mesepisternal groove punctate ( A. aurinasis subgroup). Augochlora eucnemis is similar to A. aurinasis , but can be readily diagnosed by the contiguous punctures on frons near eye notch level; presence of blue reflections on the body; posterior surface of the metapostnotum smooth on males; and punctures on the posterior surface of the mesoscutum separated by more than PD on females. This species also resembles A. almeidai sp. nov., A. lamellata sp. nov. and A. mineira sp. nov., but differs by hypostomal carina not produced, and the preoccipital ridge as thick as 0.3× OD laterally on females, and by having the posterior surface of the metapostnotum not covered with carinae on both sexes.
