Distribution.

Vietnam and Myanmar.

Remarks.

This species is most similar to Peltonotus pruinosus, a species for which only the female holotype is known. Previously, this species was only known from the male holotype specimen from Vietnam.

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.

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. 55 Peltonotus adelphosimilis 56 Peltonotus animus 57 Peltonotus brunnipennis 58 Peltonotus cybele 59 Peltonotus deltamentum 60 Peltonotus favonius.
