Spinoliella rozeni Toro and Ruz

Spinoliella (Peniella) rozeni Toro and Ruz, 1972a: 154 (holotype ♂, AMNH, seen: Travesia, Atacama, Chile]).

DIAGNOSIS: This species can be recognized by the following combination of features: small body size (5–7 mm); mesoscutum and mesocutellum weakly shiny with contiguous, minute punctures or alveoli among larger, sparser, and coarser setiferous punctures; distal margin of mesoscutellum and often entire metanotum yellow; terga with depressed apical margins semitranslucent; female pygidial plate bifid, with lateral margins straight, converging toward apex at a 40° angle; female facial fovea deep, forming a distinct groove, narrow ventrally and dorsally, medially as wide as scape; male facial fovea weakly impressed, about same width across length (about one-third width of scape); metabasitibial plate distinctly depressed on disc and delimited by weak border in female, that of male flat on disc, barely delimited by a border.

DISTRIBUTION: Chile: Tarapacá (R-I); Antofagasta (R-II); Atacama (R-III): Huasco, Chañaral, Copiapó; Coquimbo (R-IV): Elqui.

FLORAL RECORDS: Cristaria sp. and unidentified “purple mallow” ( Malvaceae ); Nolana sp. (Solanaceae) .

COMMENTS: Both male and female specimens from Los Choros Bajos (R-III) have reduced yellow maculation on the scape, pedicel, pronotal lobe, and metanotum. These male specimens with reduced maculation might be confused with those of S. opaca , but they can be easily distinguished by the characters indicated in the key.
