Description.

Integument black, with labrum and palpi reddish-brown; pubescence white; setae dark-brown.

Head. Frons transverse, coarse, moderately abundantly punctate; pubescence sparse, distinctly not obliterating integument, slightly more concentrated along coronal suture and margin of eyes; setae long, sparse. Sculpture and pubescence of vertex as on frons. Coronal suture marked from clypeus to anterior edge of prothorax. Area behind eyes with sparse pubescence. Genae with sparse pubescence towards clypeus, glabrous towards apex. Distance between upper eye lobes equal to 0.6 times the length of scape; distance between lower eye lobes, in frontal view, equal to 0.8 times the length of scape. Antennae as long as 1.3 times the elytral length; reaching elytral apex; antennal segments sparsely pubescent; scape, pedicel and antennomeres III–VII with sparse, very long setae throughout (ventrally longer and more abundant on antennomeres); antennomeres VIII–X with moderately long setae near apex; antennal formula based on antennomere III: scape = 0.96; pedicel = 0.33; IV = 1.08; V = 0.75; VI = 0.75; VII = 0.67; VIII = 0.58; IX = 0.46; X = 0.42; XI = 0.42.

Thorax. Prothorax transverse, distinctly wider between lateral tubercles and anterior margin. Pronotum coarse, deeply, abundantly punctate; pubescence sparse, slightly longer between lateral tubercles of prothorax and anterior margin; with long, sparse setae. Lateral sides of prothorax with sculpture, pubescence and setae as on pronotum; lateral tubercle spiny, curved upwards. Elytra: coarse, deeply, abundantly punctate (punctures aligned in rows); pubescence sparse, forming rows placed between rows of punctures; with long, sparse setae; lateral sides slightly expanded after middle; apex together rounded. Legs: Femora and tibiae with sparse pubescence, dorsally with long, sparse setae.

Abdomen. Ventrites pubescent. Ventrite V trapezoidal, 3.3 times as long as IV, depressed at center of distal third; apex concave.

Type material.

Holotype female: PARAGUAY, Canindeyú: Carapa, (54°23'W, 24°22'S), 22.XI.2003, U. Drechsel col. (MZSP).

Dimensions in mm (female).

Total length, 4.20; length of prothorax at center, 0.85; anterior width of prothorax, 0.85; posterior width of prothorax, 0.80; largest width of prothorax, 1.05; humeral width, 1.20; elytral length, 2.95.

Etymology.

Latin, concolor = of the same color. Relating to the uniform color of the body.

Remarks.

Mimasyngenes concolor sp. n. is similar to Mimasyngenes icuapara Galileo & Martins, 1996, but differs mainly by the spiny lateral tubercle of prothorax being notably smaller, and by antennomere III shorter than IV. In Mimasyngenes icuapara the lateral tubercle of prothorax is distinctly longer and antennomere III is about as long as IV.

Mimasyngenes concolor can be included in the alternative of couplet “5”, from Clarke (2007) (modified):
