Type material.

Holotype. Chile • Female, CNC; Rx, Mtn Alerce, Costero, E of Mirador ; 40°10'55"S, 73°26'21"W; 916 m; 2005; Brown & Berezovskiy leg.; Voucher code: CNCH 2455 GoogleMaps .

Diagnostic description.

Vein R 1 longer than pterostigma length and much longer than distance between its end and end of vein 3 RSb; pterostigma broader and not angulated at lower anterior margin; vein r usually arising at ~ 0.5 of pterostigma length; propodeum with areola defined on posterior 0.5; T 1 narrowing near posterior margin but not as strongly (its length 3.0 × its width at posterior margin, and width at anterior margin 2.0 × 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: 2.36 mm; fore wing length: 2.36 mm. Among all known species of Dolichogenidea in the New World, D. alerce can be recognized by its T 1 comparatively narrow and overall dark coloration of body and legs. Dolichogenidea rubymacpearsae is morphologically similar but it has T 1 more strongly narrowing, a much shorter vein R 1, and a characteristic pterostigma (see diagnostic for that species).

Etymology.

Named after the Alerce Costero National Park, where the holotype was collected. The Patagonian cypress ( Fitzroya cupressoides ) also known as “ alerce ”, an outstanding tree, gives its name to the park and, indirectly, to this new wasp species.
