Male. Head brownish red with black band on vertex and black spots behind eyes. Scape and pedicel black; antennomeres III–XI bicolored, basal 2/3 brownish orange and apex black. Pronotum brownish red, with six rounded black spots, forming two groups separated by a median longitudinal black band; sides of prothorax with two pairs of rounded black spots. Ventral region generally dark brown. Elytra yellowish with elongate dark-brown spots. Coxae dark brown; pedunculus of femora brownish orange and club dark brown; tibiae brownish orange except for dark-brown bases; tarsi brownish orange.

Frons with yellowish setae. Vertex with fine dense punctures; short dense yellowish setae. Antennal tubercle with smooth and glabrous apices. Dorsal region of head with fine sparse punctures. Upper eye lobes well separated, distance between them about three times width of upper lobe; lower eye lobes about three times wider than upper lobes. Genae measuring half diameter of lower eye lobes; short sparse yellowish setae.

Pedicel and antennomeres III–XII with fine shallow dense punctures; short dense yellowish setae; apices of antennomeres III–XI smooth and glabrous; antennomere III with longitudinal groove; antennomere IV with longitudinal groove, not evident at base; apical antennomeres filiform; antennomere III about twice length of scape and 1/5 longer than IV; antennomeres IV–VI subequal in length; antennomeres VII–XI gradually decreasing in length; antennomere XII half length of III and about half length of XI.

Prothorax with shiny surface; prothorax rounded at sides, with two pairs of shallow tubercles, one pair antemedian and the other postmedian; pronotum with two black, rounded tubercles near posterior margin. Pronotum ( Fig. 114 ) with coarse dense sexually dimorphic punctation, except in a median smooth longitudinal band and two elevations at sides of prothorax, which bear only fine sparse punctures and short sparse setae. Sexual punctation with deeper, rounded, somewhat irregular punctures ( Fig. 115 ); each indentation with three to nine groups of pores distributed entirely within indentations ( Fig. 116 ); between indentations are chaetigerous punctures ( Fig. 117 ). Prosternum with sexual punctures denser than on pronotum; micropunctures present between punctures, with long setae. Anterior margin of prosternun with yellowish setae. Prosternal process expanding to apex and is rounded. Mesosternum depressed. Scutellum glabrous.

Geographical distribution. The species is reported for Brazil (Goiás, Mato Grosso do Sul, Espírito Santo to Rio Grande do Sul), Argentina, Paraguay and Uruguay ( Monné, M.A., 2005) ( Fig. 157 , 161 ).

Biological data. Baucke (1955) cited Acacia sp. ( Mimosaceae ), Prunus persica (L.) Batsch ( Rosaceae ), and Eugenia uniflora L. ( Myrtaceae ) as hosts. Di Iorio (1997) reported Solanum glaucophyllum Desf. (Solanaceae) . Monné, M.A. (2005) indicated Acacia decurrens Willd. , Mimosa uruguensis Hook & Arn. (Mimosaceae) , and Prunus domestica L ( Rosaceae ) as host plants. We add Anadenanthera sp. ( Fabaceae ) as a new host plant for the species.
