Description: length: 7.5-8.1 mm; length of fore-body: 3.7; length of head: 0.09; breadth of head: 0.975; length of antenna: 2.3; length of pronotum: 1.2; breadth of pronotum: 1.5; length of elytron: 0.9; breadth of elytra: 1.15. Head dark brown, pronotum and elytra reddish-brown, abdomen brown, centre of tergites broadly infuscate; palpi, antennae and legs entirely testaceous; palpi, antennae and legs uniformy testaceous. Fore-body devoid of microsculpture, abdominal tergites with dense transverse microstriae. Habitus: Fig. 33h.

Head moderately transverse; eyes large and protruberant, about as long as temples; furrow of post-ocular border well removed from lateral margin; frons impunctate, vertex with an irregular clustr of ca. 8 large punctures, the posterior part of head with a few scattered smaller punctures. Pronotum broad, relatively short, the sides gently rounded from anterior angles to rounded base; lateral margin entirely but indistinctly bordered; puncturation coarse, fairly homogeneous, the interstices mostly narrower than diameter of punctures. Elytra short, humeral angles entirely obsolete, sides dilated in almost straight lines in anterior half, rounded thereafter; puncturation homogeneous, as coarse and dense as that of pronotum. Keels and grooves at bases of abdominal tergites moderately long; tergites III-VI with a transverse row of punctures adjacent to the anterior keels and grooves, elsewere with only sparse punctures roughly arranged in one median transverse row and a row on posterior margin; tergite VII and VIII almost impunctate.

Male: abdominal sternite VIII: Fig. 33s8; aedoeagus: Fig. 33arl.

Female: sternite IX: Fig. 33vp.

The specimens from Chute Madeleine, Pic du Pin and Fôret Nord are superficially indistinguishable from the types of the species, but the female ninth sternites of exx. from Pic du Pin (Fig. 33vpPdP) and Fôret Nord differs from those from the type locality; these allopatric specimens may therefore belong to another species.
