Head (dorsal view) showing characters of the labrum, mandible, and clypeus. 20 Peltonotus karubei (apex of labrum deeply bi-lobed; apex of mandible rounded laterally) 21 Peltonotus malayensis (apex of labrum bi-emarginate; apex of mandible rounded laterally) 22 Peltonotus vittatus (apex of labrum bi-emarginate; apex of mandible rounded laterally) 23 Peltonotus nasutus (apex of labrum weakly sinuate; apex of mandible quadrate laterally with broadly truncate apex; apex of clypeus with weak tubercle in male) 24 Peltonotus morio (apex of labrum weakly sinuate; apex of mandible quadrate laterally with broadly truncate apex; apex of clypeus without tubercle in male).

Figures 67–72.

Male parameres (with or without phallobase), dorsal and lateral views, in Peltonotus. Male parameres are highly asymmetrical, and we illustrate the lateral view that best assists in identification. 67 Peltonotus rubripennis 68 Peltonotus silvanus 69 Peltonotus similis 70 Peltonotus sisyrus 71 Peltonotus talangensis 72 Peltonotus vittatus.
