FEMALE GENITALIA – Tergum VIII and sternum VIII with numerous broad scales, sternum with *seta 2-S inserted lateral to seta 1-S; tergum IX wider than long, with median caudal emargination separating rounded lobes, each with 1–6 setae (rarely 1 lobe without setae); postgenital lobe with emargination; lower vaginal sclerite absent; insula tongue-like, with 2–4 distal tuberculi, without setae; 3 spermathecal capsules. MALE GENITALIA – Tergum IX lobes setose; sternum IX with 1 or more posterior setae; gonocoxite with numerous broad scales on lateral and ventral surfaces, dorsal surface with several short flattened setae distally on mesal margin (absent in Ae. whartoni), ventral surface with small patch of long setae proximally on mesal margin (less well developed in Ae. franciscoi), gonostylus attached apically, *gonostylus/gonocoxite index ≥ 0.73, single *preapical gonostylar claw inserted some distance from apex; claspette a small basal plaque with several short setae; aedeagus comprised of 2 lateral sclerites, each with elongate lateral teeth extending from base to apex; cercal setae absent. LARVAE – Antenna short, without spicules (long with few spicules in Ae. whartoni); seta 1-C single; seta 4-C multi-branched, inserted mesal and slightly posterior to seta 6-C; seta 5-C single, inserted posterior to setae 4,6,7-C; seta 12-C branched, inserted mesal to seta 13-C; seta 13-C single, longer than seta 12-C; *seta 14-C single; seta 19-C absent; setae 1–3-P not on common setal support plate; seta 6-P single, longer than branched setae 5,7-P; seta 5-M single, noticeably longer than setae 6,7-M; seta 6-I–V double, aciculate; seta 7-I single or double; seta 12-I absent; seta 8-II with 2 or 3 branches; seta 1-VII noticeably longer than saddle; siphon relatively short (long in Ae. whartoni), seta 1-S single, inserted distal to pecten; saddle incomplete ventrally; seta 1-X single, inserted on saddle; ventral brush (seta 4-X) with several 2–4 branched setae inserted on grid with transverse bars and *2 branched precratal setae. PUPAE – Trumpet with weakly developed tracheoid area; seta 6-CT single, much shorter than seta 7-CT; seta 11-CT longer than seta 12-CT, both single; seta 1-II short, double, rarely triple; seta 3-II,III long, single; seta 6-VII inserted mesal and posterior to seta 9-VII; seta 9-VIII with 2–5 branches; paddle with very shallow apical emargination and fringe of hair-like spicules on outer and inner margins (absent in Ae. whartoni); seta 1-Pa short, single (branched in Ae. whartoni).

Petermattinglyius was recovered as the sister to (Alanstonea + Pseudarmigeres) + Heizmannia in the morphology-based phylogeny of Reinert et al. (2009), and that clade was sister to another comprised of subgenus Lorrainea + (((genus Udaya + (subgenus Belkinius + genus Zeugnomyia)) + (genus Eretmapodites + genus Armigeres)). Petermattinglyius was recovered as the sister of genus Heizmannia + subgenus Pseudarmigeres in the study of Wilkerson et al. (2015).
The immature stages of Petermattinglyius species are normally found in bamboo and occasionally in holes in trees or logs. Females have been collected biting humans, in human-baited traps and light traps, and resting in houses.
Species of subgenus Petermattinglyius are not known to be of medical importance to humans.
