A review of Augochlora (Oxystoglossella) bees from South America: unexpected Amazonian diversity and assessment of vulnerable species Author Lepeco, Anderson Author Gonçalves, Rodrigo Barbosa text Journal of Natural History 2023 Oxford, England 2023-06-12 57 9 - 12 608 664 http://dx.doi.org/10.1080/00222933.2023.2195564 journal article 53802 10.1080/00222933.2023.2195564 0f7f9d5d-4eaf-4464-83d9-d30749f03fc5 1464-5262 8067039 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.
