Type material.

Holotype. Ecuador • Female, CNC; Napo, Quito-Baeza road ; 4,100 m; 10.ii.1983; L. Masner leg.; Voucher code: CNC 1196551 . Paratypes. Peru • 8 Males, CNC; CNC 5342682 , CNC 5342683 , CNC 5342684 , CNC 5342685 , CNC 5342686 , CNC 5342687 , CNC 5342688 , CNC 5342689 .

Diagnostic description.

Vein R 1 shorter than pterostigma length and approx. as long as distance between its end and end of vein 3 RSb; pterostigma comparatively narrow (3.0 × as long as wide) and often with lower anterior margin angulated so that it looks as having four sides; vein r arising from apical 0.7 of pterostigma; propodeum with almost no traces of areola, with only some small, poorly defined carinae from nucha; T 1 very strongly narrowing near posterior margin, its length 4.5 × its width at posterior margin, and width at anterior margin 3.0 × width at posterior margin; comparatively dark colored species, with all legs entirely dark brown to black (except for yellow-brown on posterior 0.1 of pro- and mesofemora and anterior 0.1–0.2 of tibiae); palpi, tegula and humeral complex dark brown; body length: 2.40 mm; fore wing length: 2.26 mm. Male specimens show some variation in venation, shape of T 1 and shape and sculpture of T 2. This is a very distinctive species based on rather unique T 1 shape (strongly narrowing), shape and length of pterostigma and overall dark coloration.

Distribution.

Ecuador, Peru.

Biology.

No host data available, but the fact that eight male specimens were collected the same day in the same locality suggest this species is gregarious.

DNA barcoding data.

No data.

Etymology.

The second author dedicates this species to Ruby MacEwan, daughter of Rob MacEwan. Rob wanted so much to have a species named after his daughter and I wanted to name one after him, so they are both honored in this paper. The first four letter of the species are her first name “ Ruby ”, “ mac ” is part of the last name of Rob and “ pears ” is Ruby’s mother last name.

Notes.

The male specimens are from a locality in Peru, which is> 1,000 km apart from the locality of the holotype, in Ecuador. However, they are considered the same species because of similar morphology and the fact that both localities are more than 4,000 m elevation in the Andes.
