Peytonulus Harbach, 1991

The absence of prealar setae distinguishes the adults of Peytonulus from the adults of Davismyia; the presence of upper proepisternal setae and/or the absence of leg paddles distinguish them from species of subgenus Sabethes; the presence of lower mesokatepisternal setae distinguishes them from adults of subgenus Sabethinus; and the absence of white scaling on the midtarsus distinguishes them from the adults of subgenus Sabethoides. Peytonulus larvae are easily distinguished from all other Sabethes larvae by having seta 1-VII highly modified and borne on a strong tubercle. Larvae also have seta 8-T inserted anterior or anteroventral to seta 9-T (distinction from subgenera Davismyia, Sabethes and Sabethoides), seta 10-I inserted in line with or mesal (usually) to seta 13-I (distinction from subgenera Davismyia, Sabethes and Sabethinus) and lack a comb plate and an auxiliary seta 4b-X (distinctions from subgenus Sabethinus). Peytonulus pupae are easily recognised by the absence of seta 1-VII (this seta is present in all other Sabethes). See genus Sabethes.
