Emended diagnosis. Twelve pairs of bi- or quadriserial gills [no pleurobranch on fifth or eighth thoracic somites]. Shield with rostrum well developed or reduced. Ocular acicles simple, bi- or multidenticulate. Antennal peduncle with supernumerary segmentation. Maxillule with external lobe of endopod well developed, distinctly recurved. First maxilliped with epipod well developed or absent. Third maxilliped with coxal segments approximate or somewhat separated; crista dentata usually well developed, no accessory tooth; merus usually with 1 or more spines; carpus, propodus and dactyl usually unarmed.

Chelipeds equal, subequal or unequal, often with left considerably larger, similar or dissimilar in armament; claws corneous, fingers opening in horizontal or oblique plane. Fourth pereopods subchelate or weakly semichelate, with or without preungual process developed at base of claw.

Males with paired gonopores; first and second pleomeres each with pair of pleopods modified as gonopods; unpaired, unequally biramous left pleopods on pleomeres 3–4, pleopod 5 with external ramus well developed, internal ramus rudimentary. Females usually with paired gonopores; first pleomere with or without pair of modified pleopods (gonopods); pleomeres 2–4 with unequally biramous left pleopods; pleopod 5 as in male; brood pouch usually well developed, occasionally absent.

Uropods asymmetrical. Telson with lateral indentations; posterior portion divided by median cleft into 2 subequal to markedly unequal lobes.

Type species. Pagurus setosus Filhol, 1885 .

Remarks. With the addition of the two species discussed in this study, Aeropaguristes now contains 27 species worldwide (Tab. 1). Of these, nine occur in the Americas, with four in the eastern tropical Pacific: A. lemaitrei Ayón-Parente & Hendrickx, 2012, A. mclaughlinae (Ayón-Parente & Hendrickx, 2006), A. praedator (Glassell, 1937) nov. comb., and A. waldoschmitti Ayón-Parente & Hendrickx, 2012; and five in the western Atlantic: A. hewatti (Wass, 1963), A. hummi (Wass, 1955), A. iris (Forest & de Saint Laurent, 1968), A. oxyophthalmus (Holthuis, 1959) nov. comb., and A. tudgei (Lemaitre & Felder, 2012) . The remaining species occur in the Indowest Pacific.
