Ejaculatory complex with long distal arms and clearly developed proximal arms (Figs. 1 F – G). Female. Arrangement of dorsal plates and glandularia as in male, but postero-medial plate almost circular in shape (Fig. 2 C). Integument structure, shape of coxal field, setae of legs, shape and setae of gnathosoma and palps (Fig. 2 B) as in male; clear sexual dimorphism in the shape of the genital field. Genital flaps longer, outline appears almost rectangular (Fig. 2 A); genital field caudally reaching beyond Cx-IV, pre-genital sclerite medium-large; distance between Ac- 1 and Ac- 2 larger than between Ac- 2 and Ac- 3; two setae anterior of Ac- 1, a further four to six setae between Ac- 1 and Ac- 2, as well as two setae between Ac- 2 and Ac- 3, one lateral to Ac- 2, and one seta in postero-medial corner of genital flaps.	en	Pešić, Vladimir, Smit, Harry, Datry, Thibault (2016): A redescription of Protolimnesia longa Besch, 1963 from Bolivia, with the first description of the female (Acari: Hydrachnidia: Limnesiidae).

C92AE151D6593A52FF2072578331FC10.taxon	discussion	Remarks. The specimens from Bolivia agree well in general morphology with Protolimnesia longa Besch, 1963. Protolimnesia longa can easily be distinguished from other members of the genus by a reticulate pattern of the integument, two pairs of medial and anterior dorsal plates and a small genital field. The only difference towards the type specimen from Argentina is found in the almost rectangular shape of the dorsal postero-medial plate in the male from our study compared with the almost circular postero-medial plate in the original description (see Besch 1963, fig. 2). Habitat. Protolimnesia longa seems to be a characteristic dweller of interstitial waters of ephemeral streams. The sampling site in Bolivia is an ephemeral stream located in the Sacaba area (Cochabamba, Bolivia) (Fig. 3 A – B). This stream flows about 3 – 5 months during the year, but species of several aquatic groups such as beetles (Psephenidae, Dytiscidae), dipterans (Stratiomyidae, Sciomyzidae, Ceratopogonidae, Dolichopodidae, Chironomidae), caddisflies (Hydroptilidae) and mayflies (Caenidae) are found to be able to survive in the dry sediments (Datry, unpublished data).	en	Pešić, Vladimir, Smit, Harry, Datry, Thibault (2016): A redescription of Protolimnesia longa Besch, 1963 from Bolivia, with the first description of the female (Acari: Hydrachnidia: Limnesiidae).
