Peltonotus species dorsal habitus. 13 Peltonotus mushiyaus, female 14–15 Peltonotus nasutus, male and female (respectively) 16 Peltonotus talangensis, male 17 Peltonotus tigerus, female 18–19 Peltonotus vittatus, male and female (respectively).

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).

Mentum, ventral view, showing form of apical half of mentum and form of labial palpomere 2 (in comparison to palpomere 1). 25 Peltonotus deltamentum 26 Peltonotus gracilipodus 27 Peltonotus kyojinus 28 Peltonotus malayensis 29 Peltonotus podocrassus 30 Peltonotus nasutus 31 Peltonotus nethis 32 Peltonotus pruinosus 33 Peltonotus similis 34 Peltonotus sisyrus 35 Peltonotus talangensis.

Male prolegs, dorsal view (45–49), male protarsomeres, dorsal view (50–53), and male protarsomere 5, ventral view (54), of Peltonotus. 45 Peltonotus animus (male protibia tridentate with basal tooth obsolete) 46 Peltonotus cybele (male protibia tridentate with basal tooth well developed) 47 Peltonotus malayensis (male protibia bidentate) 48 Peltonotus talangensis (male protibia tridentate with basal tooth well developed) 49 Peltonotus rubripennis (male protibia tridentate with basal tooth weakly developed) 50 Peltonotus adelphosimilis (arrow showing protarsomere 5 of male with internoapical protuberance) 51 Peltonotus favonius (male protibia bidentate) 52 Peltonotus nasutus (male protibial claw greatly enlarged) 53 Peltonotus similis (arrow showing protarsomere 5 of male with internomedial protuberance) 54 Peltonotus deltamentum (male proclaw strongly arcuate in ventral view).

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.
