Figures 45–54.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).

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.
