Included species Petermattinglyius franciscoi, Pe. iyengari, Pe. punctipes, Pe. scanloni (Reinert) and Pe. whartoni. Distribution Bangladesh, India, Indonesia, Malaysia, Myanmar, Singapore and Thailand. Bionomics Immature stages are normally found in bamboo (pots, stumps, internodes, etc.) and occasionally in tree holes or holes in logs (Reinert, 1970). Females have been collected biting humans, in human-baited traps, in light traps and resting in houses. Discussion See Reinert (1970) for descriptions and illustrations (*) of known stages for species of Petermattinglyius, i.e. Pe. franciscoi (♀*, ♂*, ♂g*, P*, L*), Pe. iyengari (♀*, ♂*, ♂g*, P*, L*), Pe. scanloni (♀*, ♂*, ♂g*), and Pe. whartoni (♀*, ♂*, ♂g*, P*, L*). The female of Pe. punctipes is described by Edwards (1921). Female genitalia of Pe. franciscoi and Pe. iyengari are partially described and illustrated by Mattingly (1959). Species of the genus are divided between two subgenera (see below). Additional descriptive information is provided in Appendix 1 for species included in the analysis. Etymology Petermattinglyius is named in honour of Dr Peter Frederick Mattingly in recognition of his many important contributions to the taxonomy of family Culicidae. The generic name is masculine, formed from his first name, surname and the Latin suffix ‘- ius ’. Recommended abbreviation = Pe.Published as part of John F. Reinert, Ralph E. Harbach & Ian J.
