Type species. Acarochelopodia delamarei Angelier, 1954 .

Adults. Female GA with three pairs of slender pgs; sgs lacking ( Bartsch 1984b: fig. 19). Ovipositor short, at rest not extending beyond GO. Genital spines not strongly sclerotized, their number and shape not known. Male GO situated as in female, but, in relation to size of GA, GO smaller than in female. Male GA with about seven pairs of setiform pgs, genital sclerites with three pairs of short sgs and three pairs of small gac (Fig. 3; Bartsch 1977b: fig. 312). AE of female and male without epimeral pores.

Juveniles. A larval and two nymphal stages known. In nymphal instars GP and AP separated. Deutonymphal GP with two pairs of gac and two pairs of pgs, but no sgs (Fig. 4; Bartsch 1977b: fig. 313). Protonymphal GP with single pair of internal gac; pgs and sgs not developed. In deuto- and protonymphs epimeral pores absent. Larva with longitudinally divided (as in adults and nymphs) or undivided AE; each half with a pair of delicate, tube-like epimeral pores (omitted in Bartsch 1977b: fig. 317).

Remarks. The ten species described are recorded from temperate and tropical regions of the Atlantic, Indian and Pacific Ocean and from tidal and shallow water areas ( Bartsch 2009a; Pepato et al. 2011). All species are psammophilous.
