Diagnosis.

Females of the new species can be readily distinguished from most other Augochlora by the distinctly contiguous coarse punctuation, especially on tergal marginal area, in combination with the mandible with a small preapical tooth produced far from mandibular apex. In addition, females can be separated from other Augochlora s. str. species by the T5 pseudo-pygidial area covered by scale-like appressed setae (similarly with Oxystoglossella species). From Oxystoglossella species it can be separated by the darkened basal area of labrum and hind coxa angulate on ventral transition between anterior and posterior surfaces. Males are diagnosed by the combination of: F1 as long as F2; hind basitarsus black; metapostnotum shorter than scutellum; T1 with reduced impunctate area medially adjacent to apical dark band (similarly with Oxystoglossella species); T2 with premarginal setae almost reaching apex on sublateral surfaces (similarly with Oxystoglossella species); and outer lobe of gonostylus ventral process with setae shorter than inner lobe.

Etymology.

Nominative feminine of intermedius, meaning in the middle, a reference to intermixed features of Augochlora subgenera found in this species.

Distribution.

Specimens were collected in Lima and La Libertad departments (Peru), western of Andean Mountains.

Comments.

The holotype and a couple of paratypes have bluish reflections while remaining specimens are mostly green with few reddish reflections, besides this color variation the specimens have very similar body ornamentation and imperceptible differences in size.
