Diagnosis, adult

This species may be separated from its congeners by the following diagnostic combination: frons with short, deep furrows along inner margins of eyes; elytral disc yellow, with infuscated apex.

Description, adult

Characters of Physiomorphus , with the following speci®c features: Body slightly elongate (TL/GEW 2.75±2.93), somewhat ovate. Head moderately wide (GHW/HL 1.00±1.11). Scape relatively elongate, parallel-sided; antennomere 2 short, moniliform, about half length of scape; antennomere 3 sub®liform; antennomeres 4±10 moniliform; antennomere 11 relatively short, narrowed at about midlength, without cleft; last maxillary palpomere distinctly securiform. Pronotum moderately to distinctly wide (GPW/PL 1.35±1.50), distinctly wider than head (GPW/GHW 1.14±1.28); lateral margins of pronotal disc straight to slightly sinuate to midlength, then evenly and slightly arcuate to anterior margin; discal depressions deep, circular and well de®ned; punctation deep and coarse, non-umbilicate; setation sparse, uniform. Elytra slightly convex, with suggestions of multiple, longitudinal costae; vestiture sparse, not obscuring coarse, somewhat irregular punctation; apical binding patch conspicuous or inconspicuous dorsally, depending on extent of apical elytral infuscation. Abdomen. Sexual setae and male genitalia not examined. Colour. Head, FIGS 53±60. Pronotum (adult, dorsal): (53) Physiomorphus atricolor Pic , m; (54) P. melanurus (Champion) , m; (55) P. suturalis Pic , holotype,; l(56) P. rufolineatus Pollock , n. sp., holotype,; l(57) P. antennatus Pollock , n. sp., holotype,; l(58) P. angustus Pollock , n. sp., paratype,; l(59) P. mimeticus Pollock , n. sp., holotype, m; (60) P. subcostulatus Pollock , n. sp, holotype,. l Scale: 1 mm.

including antennae and maxillary palpi, black except for frons and labrum, rufous; prothorax uniformly rufotestaceous; elytra rufotestaceous except for apical infuscated area (humeri infuscated in one specimen; legs rufotestaceous except for tarsi, piceous.

Diagnosis, mature larva

Length: 13.1 mm, width: 2.2 mm. Abdomen. Urogomphal plate (®gure 15) with scattered setae mainly on margins; constricted at urogomphal bases; a dorsal pair of short setae on median region; anterior angles rounded and strongly produced; posterior margin strongly concave, a pair of rounded pits on median region; urogomphi about 1.5Ö as long as median region of urogomphal plate, bearing some marginal setae, apices slightly upturned and convergent.
