Critical remarks to the two recent attempts to the revision of Bogidiella-Group of genera (often mentioned also as Family Bogidiellidae) are given and the taxonomic characteristics used for division of different genera and subgenera are discussed. Genus Somagidiella Stock 1981 is removed to the genus Afridiella G. Karaman & J. Barnard 1979 as synonym. The subgenus Eobogidiella G. Karaman 1981 is removed to the generic level. Bogidiella arganoi Ruffo & Vigna-Tagl. 1973 is removed to the subgenus Guagidiella. A new species, Bogidiella (Guagidiella) arganoides, n. sp. from well in Etla, Mexico, is established. Diagnosis of the subgenus Medigidiella Stock 1981 is modified and the key to the genera and subgenera of Bogidiella-Group of genera (=family Bogidiellidae) is composed. Diagnosis of many genera and subgenera of Bogidiella-Group of genera is given. Bogidiella (Bogidiella) semidenticulata Mestrov 1961 is partially redescribed and figured based an material from eastern Serbia, and distribution of this species is studied. New locality of Bogidiella (Bogidiella) albertimagni Hertzog is given.

Subterranean amphipod crustaceans of the suborder Gammaridea have been sampled on a regular basis from the artesian well in San Marcos, Texas, since late 1973. Water in the artesian well comes from the extensive, subterranean Edwards Aquifer, which is associated with the Balcones Escarpment and Fault Zone of south-central Texas. The taxonomically diverse amphipod fauna of the well is believed to be one of the richest of its kind in the world and is composed of five families, six genera, and 10 species. One family, four genera, and six species are newly described herein. Four distinct phylogenetic lineages are represented in the amphipod fauna: crangonyctids, hadzioids, bogidielloids, and sebids.
The zoogeographic and ecological implications of the artesian well amphipod fauna are profound. Approximately 80 percent of the species have obvious affinities with marine or brackish water species and are presumably derivatives of marine ancestors that colonized newly opened freshwater habitats during recession of epeiric seas in the Late Cretaceous. The high taxonomic diversity of the amphipod fauna is probably explained by: (1) exposure of south-central Texas to an extensive marine embayment during the Cretaceous period, (2) complex geological structure of the Balcones Fault Zone and large size of the Edwards Aquifer, and (3) ecological complexity of aquatic communities in the Edwards Aquifer.
