Description. Female lectotype. Length 2.4 mm, width 1.7 mm; body oval, convex, pronotum narrower than elytra at base, pronotum and elytra discontinuous in outline. Dorsal surface with head slightly alutaceous, feebly shiny, pronotum slightly alutaceous, shiny, abdomen smooth, shiny, lacking alutaceous sculpture. Color reddish yellow except pronotum black with anterolateral angle reddish yellow; elytron black with 5 reddish yellow spots ( Fig. 320 ); ventral surface with venter of head, prosternum, meso-, and metaventrites dark brown, abdomen reddish brown. Head punctures small, separated by less than a diameter, each puncture as large as 3 eye facets; pronotal punctures larger than head punctures, separated by less than to twice a diameter; elytral punctures larger than on pronotum, separated by less than to 3 times a diameter; metaventral punctures sparse, smaller than elytral punctures in median 1/2, larger and separated by a diameter or less in lateral 1/2. Clypeus weakly emarginate apically, lateral angle broadly rounded, surface with dense, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, brown. Pronotum narrowed from base to apex, sides straight, basal and anterior angles abruptly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange straight, narrower than remainder of protibia, outer margin smooth; sponda deep, slightly wider than flange. Carinae on prosternal process widely spaced apically, convergent toward base, joined in basal 1/4 of prosternum, connected to prosternal base by single stem. Abdomen with primary pores laterally between ventrites 4- 5 large, occupying apical 1/3 of ventrite 4, forming large, deep depression on ventrite 5; postcoxal line on basal abdominal ventrite straight in basal 1/3, rounded along apical margin of ventrite at middle, angulate in apical 2/3, extended forward; ventrites 1-6 with sparse, moderately long pubescence, basal ventrite with large punctures in median 1/3 separated by a diameter or less, remaining ventrites with punctures fine, dense, separated by less than a diameter; 5th ventrite with apical border weakly emarginate; 6th ventrite with apical margin strongly arcuate. Genitalia with spermathecal capsule short, weakly curved, enlarged in apical 1/2, bursa lost ( Fig. 321 ).

Geographical distribution. Brazil.

Specimens examined. The lectotype.

Remarks. A combination of dorsal color pattern and narrow pronotum creating a discontinuous outline of pronotum and elytra is distinctive for this species.

The female lectotype is labeled “5171 (blue disc)/ Syntype (blue bordered disc/Gaynoni Muls. Bresil (green paper).”
