Spinoliella (Spinoliella) longirostris Toro, 1995: 105 (holotype ♂, AMNH, seen: Qda. De Taltal, Region II, Chile).

DIAGNOSIS: This species can be recognized easily by the following combination of features: small body size (5–6 mm); clypeus, in facial view, distinctly projected ventrally in both sexes (fig. 10), beginning at about the inferior tangent of compound eyes in the male and projecting by more than half its length in the female; male glossa distinctly long, surpassing posterior margin of procoxae in repose; female pygidial plate narrow, with lateral margins converging toward apex at a 40° angle, narrowly rounded at apex; frons, meso- scutum, and mesoscutellum finely, contiguously punctate to alveolate, punctures or alveoli often faint on female mesoscutellar disc (thus appearing weakly imbricate); female mesobasitarsus robust, about 3.0× longer than broad; metabasitibial plate depressed on disc, setose, delimited by a strong border or carina in the female, flat, asetose, and without distinct border in the male; and female outer metatibial spur distinctly curved apically. It resembles S. aidae , S. tadeyi , and S. psamita in the small body size and general body color. However, in the female of the first two species the pygidial plate is apically bifid and the outer metatibial spur is apically straight; in the female of S. psamita the clypeus projects below the inferior tangent of the compound eyes by about one-half its length and the facial maculations are often abundant (reduced to nearly absent in S. longirostris ). The male of S. longirostris can be separated easily from that of those species and any other Spinoliella by the distinctive clypeus and long glossa.
