DIAGNOSIS: This species can be recognized easily by the following combination of traits: large body size (8–9 mm); female pygidial plate broad, with lateral margins converging toward apex at a 60° angle, apically bifid; frons, mesoscutum and mesoscutellum with minute, contiguous punctures among scattered, larger setiferous punctures (fig. 11D); female mesobasitarsus slen- der, about 3.5× longer than broad; metabasitibial plate slightly depressed and asetose on disc, delimited by a distinct border or carina in the female (fig. 11B), that of male flat, with scattered, minute setae on disc and without a distinct bor- der (fig. 11C); depressed apical margins of T5 and T6 covered by decumbent setae, except at most on apical third; and female outer metatibial spur straight apically. It closely resembles S. opaca and S. propinqua in the body size, female pygidial plate apically bifid, sculpturing of frons and mesoscutum, and general body color (dark brown to black with lateral spots on basal four terga). However, in S. opaca the facial fovea is weakly impressed, about the same width across its length in the female, and as an inverted teardrop in the male (in S. maculata the facial fovea is strongly impressed, forming a groove, and medially wider in the female, elongate in the male); the apical margins of terga are translucent in both sexes; the distal margin of clypeus is straight (medially projected in S. maculata ); the male clypeus projects about one-half width of the compound eye in profile view (about onethird in S. maculata ); and the male labrum has coarse punctures on its distal half (more finely punctate in S. maculata ) (see also comparative comments for S. opaca ). Spinoliella propinqua can be separated by the mesoscutum and mesoscutellum shinier in the female, with micropuntures shallow and often faint, particularly on the disc of mesoscutum; the apex of the pygidial plate more acute in both sexes; and depressed apical margins of T5 and T6 largely asetose, decumbent setae present at most on basal half.
