Paracriodion Fragoso, 1982

Paracriodion Fragoso, 1982: 147 ; Monné, 2005: 69 (cat.); Martins & Monné, 2005: 209 (rev.); Monné, 2012: 12; Monné, 2014: 84 (cat.).

Type-species: Criodion modestum Buquet, 1852 (original designation).

Redefinition. Head narrowed behind eyes, dorsal surface without protuberances or with posterior obtuse tubercles each side of the middle line ( P. morrisi sp. nov.). Frons wider than long. Frontoclypeal suture deep and recurved. Clypeus elevated at sides. Eyes not strangulated between lobes. Superior lobes with more or less 11 lines of ommatidia, separated by the width of a lobe. Genae same length as inferior ocular lobes. Males with antennae longer than the body, apex of antennomere X attaining elytral apices, female antennae shorter than body, antennomere XI attaining the distal third of elytra. Scape cylindrical, shorter than antennomere III, the same length as antennomeres IV and V together. Antennomeres IV–XI or VI–XI filiform, slightly flattened dorso-ventrally. Antennae densely pubescent in P. modestum ( Buquet, 1852) . Prothorax scarcely longer than wide, sides rounded, with an irregular outline. Pronotum with multiple flat or more or less prominent gibbosities and deep punctures across the whole surface; sides of the prothorax and prosternum with similar gibbosities, prothorax densely pubescent in P. modestum , with or without two transverse sulci. Prosternal process projected behind; mesosternal process without projections. Elytra shining, with sparse hairs in P. modestum and P. romani ( Aurivillius, 1926) or glabrous ( P.morrisi sp. nov.). Apex of the elytra semicircularly truncated with a short spine in the sutural angle. Femora fusiform, distal extremities unarmed; tibiae with a short distal projection.

Remarks. Paracriodion has similarities with Butherium Bates, 1870 , by the shining, almost without pubescence, surface. In Butherium the frons is reduced; occiput broadly curved; antennal tubercles flattened and (in profile) below median longitudinal body axis. In Paracriodion the frons is elongated; occiput subtly curved or straight; antennal tubercles (in profile) above mid longitudinal body axis (Fragoso, 1982). Paracriodion can be distinguish from Iuati Martins & Galileo, 2010 by the unarmed sides of the prothorax and the pronotum with gibbosities and crateriform punctures; in Iuati , the sides of the prothorax are armed with a prominent median tubercle, and the surface of the pronotum ornamented with large crateriform punctures, without gibbosities.
