The superfamily Bogidielloidea is one of the most wide-ranging hypogean amphipod taxa currently known, comprising over 130 species in 43 genera occurring on every continent except Antarctica. This large distribution among such cryptic organisms is curious, especially when combined with weak morphological characters uniting the superfamily. A unique new genus and species of bogidielloid amphipod, Simplexia longicrus, gen. et sp. nov., described from Terrell County, Texas, sheds light on the evolutionary relationships within this grouping. Molecular phylogenetic analyses of the order Amphipoda using two nuclear genes and one mitochondrial gene reveal that this species and the sympatric Parabogidiella americana form a clade removed from other sequenced members of Bogidiellidae sensu stricto, and, as such, the two species are placed in the newly erected Parabogidiellidae, fam. nov. Additional phylogenetic analyses of the cosmopolitan Bogidiellidae are recommended to further resolve its systematics.

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.

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.
