Peregrinacarus Bartsch, 1999

Type species. Peregrinacarus reticulatus Bartsch, 1999.

Adults. Genital and anal plate fused in both female and male. Female GA with four to six pairs of slender pgs, each genital sclerite with zero to one sgs. GO with three pairs of internal gac arranged in line. Posterior-most pair larger than anterior ones; the former situated near end of GO (Bartsch 2001b: fig. 5). Ovipositor at rest extending beyond GO. Apex of ovipositor with two anterior pairs of spiniform, smooth genital spines; shape and number of posterior pairs of spines not known. Male GO somewhat smaller than that of female and removed from end of GP. GA with about 40 slender pgs and five to six pairs of sgs. Acetabula arranged in line; two anterior pairs small, posterior-most pair slightly enlarged (Bartsch 1999b: fig. 4). AE of adults without epimeral pores.

Juveniles. With one larval and two nymphal stages. In nymphs GP and AP separated. Deutonymphal GP with two pairs of pgs, zero to two pairs of sgs and two pairs of large internal gac (Bartsch 1999b: fig. 19, 2001b: fig. 18). Protonymphal GP with single pair of large gac, internal as in deutonymph; pgs and sgs lacking (Bartsch 1999b: fig. 23, 2001b: fig. 21). Larva with tube-like epimeral pores.

Remarks. The two species at present known are from southern hemisphere coldwater areas, from brackish to fresh water rather close to the sea (Bartsch 1999b, 2001b; Pešić et al. 2010).
