Derivation of speci W c epithet

This new and striking species is named for the orange and black colouration, and the elongate antennomeres, both of which are indicative of possible membership in a mimicry complex.

Diagnosis, adult

This species may be separated from its congeners by the following diagnostic combination: antennomeres ¯abellate from antennomere 3; body surface with dense vestiture; colour pattern vividly contrasting black and orange.

Description, adult

Characters of Physiomorphus , with the following speci®c features: Body elongate (TL/GEW 3.23±3.65), parallel-sided. Head. Scape relatively short, subglobular; antennomere 2 very short, less than one third length of scape; antennomeres 3±10 ¯abellate, becoming more produced towards apex of antenna; antennomere 11 with distal cleft; distal maxillary palpomere securiform; eyes relatively small and widely separated. Pronotum moderately wide ( GPW /PL 1.33±1.41), distinctly wider than head ( GPW /GHW 1.24±1.26); lateral margins of disc subparallel basally to near middle, then slightly and evenly arcuate to anterior margin; discal depressions relatively shallow, indistinctly de®ned, especially laterally; punctation shallow, umbilicate, irregular; setation dense, especially laterally (orange areas), with setae somewhat whorled. Elytra relatively convex, with suggestions of multiple, longitudinal costae; epipleuron present to apex, gradually and evenly narrowed posteriorly; vestiture relatively dense, obscuring very ®ne punctation. Abdomen. Sexual setae and male genitalia not examined. Colour. Black, except for the following areas, orange: narrow margin of frons along inner eye margin, area of head behind eyes, lateral areas on pronotum, humeri and central third of elytra; ventral body surface mixture of rufous and piceous; legs with rufous femora and piceous tibiae and tarsi.
