The available specimens of Pelonium atrigonatium key out to P. nigroclavatum CHEVROLAT from which P. atrigonatium specimens are distinguished by showing elytral asetiferous punctures that nearly extend to the elytral apex, black distal marking on the femora, and more oblong pronotum.
D e s c r i p t i o n: Size: Length 9.0 mm; width 3.0 mm. Form: As in Fig. 360 View Figs 358-361 . Color: Cranium and pronotum castaneous; antennal capitulum, prothoracic venter and pterothorax black; antennal fundus testaceous; elytra bicolorous, mostly yellow, with 3 seta of small black markings, 3 on/near humeral angle, 3 at elytral middle, 2 near elytral apex; legs bicolorous, mostly yellow, distal limits of femora and basal limits of tibiae black; abdomen yellow. Head: Cranium coarsely punctate; antenna ( Fig. 98 View Figs 92-100 ) capitate, funicular antennomeres shorter towards capitulum, capitular antennomeres 9 and 10 triangular and slightly angular in anterodistal region, antennomere 11 ovoid; eyes large, coarsely facetted, eye wider than frons (EW/FW 42/31). Thorax: Pronotum ( Fig. 154 View Figs 153-162 ) oblong (PW/PL 120/155), disc coarsely punctate, lateral tubercles well developed; elytra sculptured with 11 striae of large asetiferous punctures that best defined in elytral basal 1/3 rd, punctures obsolete near posterior region sutural margin, punctures end very near elytral ape (EL/EW 390/95). Abdomen: Pygidium scutiform; aedeagus as in Fig. 260. View Figs 255-261
