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 36–44.

Maxilla, ventral view, showing mala with or without lamellate setal brush (setae thick and strongly flattened), and showing stipes with or without setae curly at apices. 36 Peltonotus animus 37 Peltonotus cybele 38 Peltonotus deltamentum 39 Peltonotus favonius 40 Peltonotus karubei 41 Peltonotus malayensis 42 Peltonotus mushiyaus 43 Peltonotus talangensis 44 Peltonotus tigerus. Arrows indicate lamellate setal brush.

Figures 61–66.

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. 61 Peltonotus fujiokai 62 Peltonotus gracilipodus and Peltonotus podocrassus 63 Peltonotus karubei 64 Peltonotus malayensis 65 Peltonotus morio 66 Peltonotus nasutus.
