Miguellus , gen. nov.

( Figs 14–17 )

Type species: Miguellus monnei sp. nov.

Etymology. The genus is named for Miguel A. Monné (Museu Nacional do Rio de Janeiro, Rio de Janeiro, Brazil—MNRJ), with the Latin suffix “ellus” = small, relating to the small size of the type species. Masculine gender.

Description. Male. Body slightly flattened; head hypognathous; frons slightly transverse; antennal tubercles somewhat elevated, in frontal view, their inner margins together V-shaped; antennae distinctly longer than body; scape cylindrical, slightly widened toward apex, without carina on inner side, without dense long setae; antennomere III with sparse, long, erect seta ventrally, about as long as scape, not widened; antennomere IV shorter than III; prothorax transverse, with large, lateral subconical tubercle, placed at basal half, ending in acute, backward directed spine; pronotum densely pubescent; prosternal process laminiform; mesoventral process about as wide as 1/4 of mesocoxal cavity; elytra parallel-sided, with long spine at outer apical angle, deeply notched between outer spine and rounded sutural lobe; elytra with humeral carina, from base to apex, well-marked; epipleuron vertical, not visible dorsally, narrowed from base to apex; dorsal elytral surface with well-marked carina from base to near apex, without long erect setae; femora pedunculate-clavate, especially meso- and metafemora; metatarsomere I about as long as II–V together; last abdominal segment gradually narrowed toward apex, with outer angles spiniform.

Remarks. Miguellus differs from Piriana gen. nov. by the pronotum without a longitudinal dark central band. It differs from Sparna by the elytra parallel-sided (distinctly widened toward distal quarter in Sparna ), and from Carterica by the humeral carina reaching elytral apex (present only in basal 2/ 3 in Carterica ).

Species included: Miguellus monnei sp. nov. ( Figs 14–17 ).
