Spinoliella (Peniella) opaca Rodríguez, Toro, and

Ruz, 2001: 101 (holotype ♂, PUCV, seen: Quebrada Los Choros, Coquimbo, Region

IV, Chile).

DIAGNOSIS: Both sexes of this species are most similar to S. maculata and S. propinqua . It can be separated from both species by the following combination of traits: T1–T5 with depressed apical margins semitranslucent (fig. 13C); facial fovea shallow, not forming a distinct groove, about the same width across its length in the female (fig. 13A), as an inverted teardrop in the male; male clypeus projecting about one-half width of compound eye in profile view; and male labrum with coarse punctures on its distal half (fig. 13B).

DISTRIBUTION: Chile: Atacama (R-III): Huasco; Coquimbo (R-IV): Coquimbo, Elqui.

COMMENTS: This species is easily recognized by the characters listed and illustrated in the original description ( Rodríguez et al., 2001). Some specimens of both sexes from Tongoy (Region IV) are larger than those from other localities, and the metasomal terga of the female are also more maculated, with T2 to T4, and sometimes T5, having a complete band to a medially separated band (each tergum with sublateral maculation in S. opaca from other localities).
