Spinoliella herbsti (Friese)   : Toro and Ruz, 1972a:

149.

DIAGNOSIS: This species can be recognized easily by the following combination of features: large body size (6–10 mm); female pygidial plate broad, with lateral margins converging toward apex at a 60° angle, apically bifid (fig. 8F); mesoscutum and mesoscutellum usually smooth and shiny (rarely weakly imbricate), with scattered punctures separated by at least a puncture width on disc (fig. 8C); female mesobasitarsus slender, 4.2× longer than broad; and metabasitibial plate not delimited by a border or carina (fig. 8D, E). It resembles S. maculata   and S. confusa   in the large body size and generally dark brown to black body color. However, in both sexes of S. maculata   the mesoscutum and mesoscutellum are minutely punctate (sometimes appearing strongly imbricate at low magnifications) between large, coarse, setiferous punctures; the female pygidial plate is more pointed; and the female metabasitibial plate is delimited by a strong carina. In S. confusa   the female pygidial plate is narrow, with sides converging at 40° angle (fig. 6F), the metabasitibial plate is delimited by a strong carina in both sexes (albeit not as well defined in the male), and the male mesoscutum and mesoscutellum are minutely, shallowly punctate between large, coarse, setiferous punctures. Also, the apex of the male pygidal plate is more acute in S. confusa   than in that of S. herbsti   .

DISTRIBUTION: Chile: Coquimbo (R-IV): Coquimbo, Elqui, Limari; Valparaíso (R-V): Valparaíso.

FLORAL RECORD: Cristaria sp.   ( Malvaceae   ).

COMMENTS: The following variations, sometimes among specimens from the same locality, were noted in the color of the body pubescence as well as in the yellow or sometimes cream integumental maculation: pubescence ranging from yellowish, light reddish brown to white; pronotal lobe sometimes maculate; distal margin of mesoscutellum and metanotum with thin yellow band sometimes diffuse (often absent in the male); tibiae and tarsi dark reddish brown with reduced maculation or entirely yellow; and discs of female T3‒T5 with bands often medially interrupted. Specimens of both sexes from Tongoy (Elqui Province) are sometimes lighter in color than specimens from other localities, particularly in the legs (tibiae and tarsi largely yellow) and metasoma (light reddish brown with cream maculation). Some males from the Province of Limari (Region IV) are significantly larger (~ 10 mm in body length), with the inner compound eye orbits distinctly diverging ventrally; also, the mesoscutum and mesoscutellum are weakly imbricate in some specimens and thus they are easily confused with S. confusa   . However, in S. confusa   the mesoscutum and mesoscutellum are minutely punctate, the apex of the pygidial plate is more acute, and the metabasitibial plate is bordered by a strong ridge and is sparsely punctate on the disc (metabasitibial plate bordered by a weak ridge and densely punctate in S. herbsti   ).

Spinoliella herbsti   occurs in central Chile whereas S. confusa   occurs toward the north, in regions III and IV. Both species appear to occur in sympatry in Coquimbo (Region IV).
