Contribution to the knowledge of the Amphipoda 121. Revision of Bogidiella-group of genera with description of some new taxa (fam. Gammaridae)

Revision of Bogidiella-group of genera (fam. Gammaridae) is made. New genus Marinobogidiella, n. gen, with a type-species Bogidiella tyrrhenica Schieeke 1979 is established. Genus Bogidiella Hertzog 1933 is divided into 2 subgenera, based on shape of palp of maxilla 1: subgenus Bogidiella Hertzog 1933 with a type-species Bogidiella albertimagni Hertzog 1933 (2-segmented palp of maxilla 1) and subgenus Eobogidiella, n. sbg. with a type-species Bogidiella purmamarcensis Grosso & Ringuelet 1979 (1-segmented palp of maxilla 1).
The species of subgenus Bogidiella Hertzog 1933 are divided into 4 groups regarding the modifications of pleopods and uropods in males: group A (Bogidiella s. str.) with unmodified uropods and unmodified pleopods 1-3 in males; group В with modified pleopods in males; group С with modified uropod 1 in males; group D with modified uropod 2 in males.
Two new species from Mexico are established: Bogidiella (Bogidiella) mexicana, n. sp. and Bogidiella (Bogidiella) chitalensis, n. sp. Diagnosis and key to the genera of Bogidiella-group of genera are presented, synonymy and distribution of all species of genera Bollegidia, Afridiella, Paracrangonyx, Parabogidiella, Pseudingolfiella, Kergueleniola and Marinobogidiella are given.
