Genus Caenaugochlora Michener

Diagnosis. Most species of Caenaugochlora are similar in general appearance to those of the genus Pseudaugochlora ; however, the latter genus has a strong ridge on the vertex and a pointed galeal apex. From the related genus Augochloropsis , Caenaugochlora differs in the absence of a notch on the tegula, the non-lamellate pronotal dorsal ridge, and the orthogonal epistomal sulcus.

Description. Female: Mandible with subapical tooth variously defined. Labral distal process narrowly triangular; basal elevation orbicular; teeth absent. Prementum not greatly elongate. Galeal apex rounded; galeal comb absent; galeal base extending to stipital base. Hypostomal ridge carinate; anterior angle rounded. Length of malar space less than basal mandibular width except in C. silvicola malar space as long as basal mandibular width. Epistomal sulcus orthogonal. Ocelli not greatly enlarged; ocellar furrow absent. Vertex not expanded or ridged behind ocelli. Preoccipital ridge sharply angled or carinate. Pronotal dorsal ridge carinate; lateral ridge rounded to carinate. Mesoscutal anterior border rounded; mesoscutal lip rounded. Tegula oval. Probasitarsal brush present; inner metatibial spur pectinate. Apex of marginal cell truncate; distal hamuli with irregular spacing pattern. Propodeal pit narrow. Male: Mandible simple. Labrum with distal process narrowly triangular as in the female; basal area notched. Antennae extending back to mesoscutellum; second flagellomere about as long as first flagellomere. Inner metatibial spur serrate. Metasoma oval. Apical margin of metasomal sternum III variable, straight, arcuate, or notched; apical margin of metasomal sternum IV variable, lateral projections present or not; apical margins of metasomal sterna V and VI emarginate; apical margin of metasomal sternum VII with median projection; spiculum narrow; proctiger unmodified. Gonobasal bridge narrow; dorsal lobes weak; basal process of gonostylus and parapenial lobe present or absent; dorsal process partly membranous; ventral surface of penis valve with prong.
