Description. Male holotype. Length 3.0 mm, width 2.4 mm; body elongate oval, convex. Dorsal surface with head slightly alutaceous, weakly shiny, pronotum slightly alutaceous, shiny, elytron smooth, shiny. Color yellow except pronotum with dark brown basomedian macula extended slightly more than 1/2 distance to anterior pronotal margin, macula with anterior border widely, deeply emarginate with yellow, entire lateral 1/3 of pronotum yellow; elytron brown with 5 yellow spots arranged in rows of 2 each with apical spot, scutellar spot rounded, mediolateral spot projected inward, discal spot oval, apical spot transversely oval with anterior border feebly emarginate ( Fig. 265 View Figures 254-270 ); ventral surface with head, prosternum brown, meso- and metaventrite dark brown; abdomen yellow except median portion of ventrites 1-3 brown. Head punctures small, separated by less than a diameter, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less, elytral punctures larger than on pronotum, separated by a diameter or less; metaventral punctures slightly larger than on elytron, separated by a diameter or less medially, larger and separated by less than a diameter in lateral 1/3. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/3, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex, ventrite with sparse, long pubescence and coarse, dense punctures medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite not depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/5 as long as paramere, slightly asymmetrical, sides convergent from base to rounded apex; paramere Pvl, lower margin produced medially, curved upward to rounded apex ( Fig. 266, 267 View Figures 254-270 ); sipho strongly curved in basal 3/4, without visible alae, basal capsule with inner arm short, narrow, outer arm slightly wider and longer than inner arm, with accessory piece, basal border broadly emarginate ( Fig. 268, 269 View Figures 254-270 ).

Female. Similar to male except head with basomedian macula extended to anterior pronotal margin. Genitalia with spermathecal capsule slightly elongate, curved medially, wide in basal 1/2, then narrowed to acute apex of cornu; bursal cap oval with 3 faintly sclerotized arms, apical strut long, slender except apical 1/4 spatulate ( Fig. 270 View Figures 254-270 ).

Variation. Length 2.7 to 3.0 mm, width 2.1 to 2.4 mm. Shape of mediolateral spot variable from elongate, strongly projected inward, to short, somewhat oval.

Type material. Holotype male; Paraguay, Hohenau. Alto-Parana. J. Jacob. B.M. 1945-814. ( BMNH) . Paratypes; 2, same data as holotype ( BMNH) ; 1, Brasilien, Nova Teutonia , 27 o 11’B. 52 o 23’L., Jan. 1939, Fritz Plaumann, Brit. Mus. 1946-191 ( BMNH) .

Geographical distribution. Brazil, Paraguay

Remarks. The brown elytron, crisply defined elytral spots, and male genitalia are the only somewhat distinctive criteria for this species.
