Notes

A specimen from Para in MNHN has the label `Lacconotus foveicollis -type-’. I was unable to ®nd any subsequent reference to this name, and it is probably unpublished.

Diagnosis, adult

This species may be separated from its congeners by the following diagnostic combination: head relatively elongate (GHW/HL 0.90±0.95); antennomeres 4±10 distinctly serrated; pronotal punctation shallow, distinctly umbilicate.

Description, adult

Characters of Physiomorphus , with the following speci®c features: Body moderately elongate (TL/GEW 3.03±3.27), somewhat ovate. Head relatively long (GHW/HL 0.90±0.95); scape elongate, parallel-sided; antennomere 2 moniliform, about half length of scape; antennomere 3 relatively elongate, triangular; antennomeres 4±10 subserrated, distinctly transverse; antennomere 11 short, slightly constricted distal of midlength; last maxillary palpomere slightly expanded, securiform. Pronotum slightly wide (GPW/PL 1.22±1.39), moderately wider than head (GPW/ GHW 1.11±1.25); lateral margins of pronotal disc rounded, somewhat divergent anteriorly in basal half, then distinctly arcuate to anterior margin; discal depressions deep, well de®ned, circular; punctation shallow, distinctly umbilicate; setation FIGS 29±36.

relatively sparse. Elytra distinctly convex, with suggestions of multiple, longitudinal costae; vestiture relatively sparse, not obscuring relatively ®ne and dense punctation; apical binding patches slightly visible dorsally.
