Type material.
Holotype. Peru • Female, CNC; Amazonas; 6°53'S, 77°40'W; 2,000 m; 12.ii.1973; J. Helava leg.; Voucher code: CNC 1196966. Paratypes. Peru • 4 Females, 3 Males, CNC; CNC 1180037, CNC 1180087, CNC 1180095, CNC 1180105, CNC 1196543, CNC 1196548, CNC 1196885.
Diagnostic description.
Fore wing veins r and 2 RS strongly angulate; T 1 mostly strongly sculptured, T 2 entirely smooth; T 1 mostly parallel-sided but slightly widening centrally, its central length> 2.0 × its width at posterior margin; T 2 comparatively narrow and sub-quadrate, its width at posterior margin 2.0 × its central length; pterostigma mostly yellow-white with thin brown margins; first and second pair of legs almost entirely yellow (except for pale brown mesocoxa), third pair of legs mostly brown to dark brown (except for yellow trochanter, trochantellus, anterior 0.1 and posterior 0.1 of metafemur, and anterior 0.5–0.6 of metatibia); T 3 mostly yellow (only pale brown on central part); body length: 2.50–3.16 mm; fore wing length: 2.69–3.13 mm. Among all species with T 1 strongly sculptured but T 2 smooth, this species is clearly distinguishable based on its metasoma coloration, especially its T 3 mostly bright yellow with only central area brown; other diagnostic characters include the sub-quadrate shape of T 2 and strongly angulate veins r and 2 RS in fore wing.

Etymology.
Named after the Department of Amazonas, Peru, where all specimens were collected, in recognition of the extraordinary biodiversity of the region.
Notes.
All paratypes were collected in the same place and same date than the holotype, which could indicate that this is a gregarious species. The coordinates of the collecting locality (as given in the labels of all eight specimens) are probably inaccurate, as they fall outside of the Amazonas Department, in the neighboring San Martin Department; also the elevation of the place indicated by such coordinates is much higher (~ 3,400 m) than the elevation mentioned in the labels (2,000 m), and there are no roads or any access to that point. Instead, we suspect that the actual collecting locality must have been some 20 km northwest of the coordinates indicated in the labels, in the vicinity of the town of Leimebamba, where there is a paved road, several attractions and lodging facilities, and the elevation of the area is ~ 2,000 m.
