Diagnosis. Tupiniquim pronotalis can easily be differentiated from T. confusa (in parenthesis) by the following features: four setiferous pores on each side of vertex organized in two longitudinal lines (setiferous pores form a small cluster of three on each side of vertex near eyes); posterior margin of pronotum with two small depressions (posterior margin of pronotum without depressions); pronotal surface almost smooth, with minute punctures (pronotal surface finely textured); elytra with punctures barely organized in rows (elytra with punctures confusedly organized); media n lobe of aedeagus at apex straight in lateral view (median lobe of aedeagus bent ventrally).

Description. Body 1.62–1.72 mm long and 0.91–0.97 mm wide. Color reddish brown, except antennae and legs light brown. Frons and vertex in the same plane. Supraorbital pore almost indistinguishable from three or four setiferous pores placed in a longitudinal line ( Fig. 26 ). Ridge from inner margin of antennal socket to eye inclined towards insertion of antenna ( Fig. 26 ). Pronotum rectangular, width 1.46 times length ( Fig. 23 ). Posterior margin of pronotum with two small depressions close to posterior angles ( Fig. 27 ). Surface of pronotum almost smooth, with both minute punctures and short pilosity almost imperceptible. Elytra with punctures, weakly organized in rows ( Fig. 24 ).

Median lobe simple, tubular, in ventral view lateral expansion slightly shorter and closer to apex, apex with short, wide denticle; in lateral view abruptly curved basally, apex straight ( Fig. 28 ).

Etymology. The specific epithet refers to one of the distinctive characteristics of this species, its large pronotum that in this species has two small depressions on posterior margin.
