Diagnostic description.

Length: 2.05-2.25 mm (avg. 2.13 mm); width: 1.85-2.01 mm (avg. 1.95 mm). Body rather round, elongate oval, weakly depressed, rufescent, often faintly bicolored, with the central portion of the elytra darkened; ground punctation rather fine and sparse; frons and epistoma depressed in middle, supraorbital stria complete, meeting frontal at sides, frontal stria complete, well impressed, weakly sinuate through depression; epistoma with sides raised; labrum weakly emarginate; each mandible with very small basal tooth; prescutellar impression oval, barely larger than scutellum; pronotal disk with few secondary punctures near sides; marginal pronotal stria complete along sides and front, strongly crenulate in front; lateral submarginal stria complete; median pronotal gland openings annulate, slightly> 1/2 pronotal length behind anterior margin; elytron with single, complete epipleural stria; outer subhumeral stria present in apical one-third, inner absent; dorsal stria one weakened to obsolete in apical 1/2, stria two and three complete, striae four and five both present in apical 1/2, sutural stria in apical 2/3; propygidium with secondary punctures dense almost throughout, sparse only along posterior margin; pygidial secondary punctures smaller and sparser; prosternal keel shallowly emarginate at base, striae well-impressed joined along basal margin, slightly sinuate, united anteriorly; prosternal keel-lobe junction slightly narrowed, lobe short, rounded, with complete marginal stria; mesoventrite wide and short, produced anteriorly at middle, with fine marginal stria often interrupted at middle, continued at side by short postmesocoxal stria which ends behind mesocoxa; meso-metaventral stria bluntly angulate at middle, reaching anterior third of mesoventrite; lateral metaventral stria directed posterolaterally, nearly reaching middle of metacoxa; metaventrite impunctate; 1st abdominal ventrite with complete inner and abbreviated outer lateral striae; protibia with outer margin sinuate, ‘scalloped’, more weakly so in basal 1/2; meso- and metatibiae with fine marginal spines those of mesotibia more numerous and robust. Male: S8 with apical setal fringe; aedeagus with basal piece nearly 1/2 length of tegmen; tegmen with sides slightly widened to middle, evenly narrowed to bluntly rounded apices, apex slightly curved ventrally in lateral view; medioventral process very strong, produced at basal fourth; median lobe ~ 3/4 tegmen length, basal apodemes abruptly narrowed in basal 1/3.

Etymology.

The species name is a contraction of Mata Atlantica, the Brazilian Atlantic Forest globally recognized hotspot on which this species largely depends.

Distribution.

This species is known mainly from coastal (Atlantic forest) areas of southeastern Brazil. However, it also extends inland through Santa Catarina and into Paraguay.

Remarks.

While similar in most characters to other species in this group, this species is considerably larger than the others. They are also frequently faintly bicolored (redder anterad), have the lateral submarginal stria complete, and have the prosternal keel striae well impressed, united anteriorly.
