Spinoliella ruzi Compagnucci, 2015: 83 (holotype ♀, MACN: Mendoza, Argentina).

DIAGNOSIS: This Argentinean species is quite similar morphologically to S. rufiventris from Chile. It can be separated by the narrower pygidial plate of the female and the slender median process of S8 of the male (fig. 20F).

MATERIAL EXAMINED (n = 1♀, 3♂♂): Argentina: 1♀, 3♂♂, nr. Nahuel Huapi [Neuquén], -41.02984, -71.312778, 927 m, 24.i.2007 [24 January 2007], vane trp, L. Packer (1♀, 2♂♂ PCYU, 1♂ SEMC).

DISTRIBUTION: Argentina: Mendoza, Neuquén.

COMMENTS: This species was described from Laguna Diamante, San Carlos, Mendoza, a locality in west-central Argentina about 20 km from the border with Chile. The specimens examined in the present work were collected near Nahuel Huapi Lake in southern Neuquén, Argentina, about 700 km south of the type locality.
