Diagnosis. Body with reddish-brown colouration, without metallic green reflections; clypeal margin and pronotum dark brown; clypeus subrectangular with rounded anterior margin and anterior angles; antennal club about 1.5x longer than antennomeres II–VII combined; scutellar plate with broadly rounded base and sides straight; apex of elytral marginal areas with acute angles; humeri densely punctate; elytra with strong striae; protibial spur about 2.8x longer than wide.

Redescription. Female. Body. Shape elongate oval; reddish-brown; frontoclypeal suture dark brown; antenna orange to dark brown; pronotal margins reddish brown at sides and dark brown at apex and base; scutellar plate marginal areas reddish-brown to dark brown, brighter and smaller in width at apex, increasing gradually to darker and thicker at base; orange setae scattered near apex; elytra reddish-brown, with marginal areas dark brown, without metallic green reflections (Figure 9 (a,b)). Length 30.28–31.00 mm. Humeral width 15.94 mm. Elytral width 17.69–18.50 mm. Head. Clypeus about 2x wider than long; subrectangular, with apex and angles weakly rounded; concavity weak at middle, moderate at apex; frontoclypeal suture almost straight, with curvilinear extremities very straight laterally; strongly striate; densely puctate; punctures moderate large to large; glabrous; frons about 1.50x longer than clypeus; punctures small to large, moderately to densely punctate; glabrous; mandibles with rounded external border, forming an almost right angle between scissorial region and apex; scissorial region slightly concave; small punctures at middle, moderately to densely punctate; scissorial region and apex of external border with setae sparsely to moderately distributed (apex and disc) (Figure 9 (c)); maxillary galea with three teeth; apical tooth longer than basal and median teeth (of similar size); small basal tooth with a small seta; apex of prementum moderately emarginate; last labial palpomere about 0.75x shorter than palpomere II (Figure 9 (e)); labrum weakly emarginated (Figure 9 (e)); antennomere II subconical, antennomere III subcylindrical, antennomeres IV and V subquadrate, antennomere VI subconical and VII subelliptical; antennal club about 1.50x longer than antennomeres II–VII combined. Thorax. Pronotum transverse, about 1.60x wider than long; punctures small to moderate, moderately to densely punctate (Figure 9 (a)); glabrous at disc; marginal areas with small and moderate, sparsely distributed setae; strongly striate; longitudinal midline with concavity at the apex; scutellar plate subtriangular, straight sides, broadly rounded at the base; setae small and moderate, moderately to densely distributed; surface moderately striate; punctures small to moderately large, sparsely to moderately punctate on the sides and densely at disc. Elytra. About 1.20x longer than wide; strongly striate; punctures small to large, sparsely to densely distributed; humeri with small to moderate punctures, densely punctate; interstriae with large coalescent punctures, (Figure 9 (a,b)); elytral apex with acute angles; glabrous. Legs. Protibial spur about 2.8x longer than wide; mesotibiae and metatibiae with two carinae; apex of mesotibia with about 14 spine-like setae and metatibiae with about 29 spine-like setae.

Male. Unknown.

Etymology. The species name is derived from Latin, cribricollis = crībrum (= riddled) and collis (= neck), referring to the strongly punctate pronotum.

Distribution. São Paulo (Jacareí and Ipiranga) (Figure 19).

Remarks. According to Ohaus (1912), the type specimens were deposited at ‘Museum of São Paulo’ (MZSP). But with the deposition of the Ohaus collection in ZMHB the lectotype from Jacareí found its way to Berlin, where it has been ever since. In agreement with Johannes Frisch (ZMHB), the specimen was finally transferred to the MZSP. The second specimen (paralectotype) from Ipiranga was found in the collection of Antonio Martínez, and is now deposited in the Canadian Museum of Nature (CMN).
