The increasing number of world-wide discoveries of subterranean amphipods, especially during the last two decades, has led to additions of numerous new taxa in the stygobiont family Bogidiellidae s. lat. To date, the family is composed of 23 genera and 11 subgenera, and approximately 110 described species. However, given the uneven quality of generic and subgeneric diagnoses in the literature, there is considerable confusion regarding the status of some of the taxa at these levels. Even the family itself lacks a clear definition. In order to gain a better knowledge of the phylogeny of this group, a cladistic analysis, employing both PAUP 3.0s and MacClade, was performed on the genera and subgenera currently assigned to the Bogidiellidae s. lat. Supported by the results of this analysis, the taxonomic structure of this group is completely revised above the species level. The revision excludes 5 genera from the family, all remaining subgenera are elevated to generic level. Four taxa are split, resulting in 5 new genera. The family Bogidiellidae now consists of 33 genera.

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.

Three new species of the genus Bogidiella HERTZOG (Crustacea, Amphipoda, Gammaridae) are described from subterranean waters of Mexico and Guatemala.
Two of these species (sbordonii, arganoi) have been collected during the biospeleological researches in Mexico (1969, 1971) promoted and financed by the Accademia Nazionale dei Lincei. During, these researches, also Bogidiella tabascensis VILLALOBOS, the only one species hitherto known from Central America, has been found in the type locality (Tabasco, Grutas de Cocona), and also in a new one in the Chiapas state (Grutas de Rancho Nuevo, at 2275 m).
Bogidiella sbordonii n.sp. (Mexico, Chiapas, Cueva de Cerro Brujo) and Bogidiella holsingeri n.sp. (Guatemala, Alta Verapaz, Cueva Seamay and Cueva Sepacuite n. 2) are two cave dwelling species, and have a relatively large size (respectively 7 mm and 4,5 mm); Bogidiella arganoi n.sp. (Mexico, Veracruz, Paraje Nuevo, well) is a phreatic species and has a relatively little size (2 mm).
The differences between the four Central American Bogidiella species are shown in table.
The last part of this work deals with the position of the Central American species within the genus Bogidiella, and, as far our present knowledge permits us to see, it is not possible to groups of species, based on systematic relationships, since the Bogidiella species have a complex of characters variously combinated and recurring within the various taxa just now described.

At least 18 species of Europe, Africa, Asia, Middle and South America, belong to the genus Bogidiella Hertzog 1933 (= Jugocrangonyx S. Karaman 1933). This paper gives a catalog of all the species well known today, with their bibliographical data and their occurrence. The Authors then examine the systematic position of the genus Bogidiella which has been classified in a special family (Bogidiellidae) by some authors, and which is considered to belong to the Gammaridae by others. The analysis of the features of this genus made us decide to include it in the Gammaridae family, of which it forms a particular group, in any case (Bogidiella group). Pseudingolfiella Noodt and, probably, Parancrangonyx Stebbing and Kerguelenella Ruffo also belong to this group which is characterized by the pleopods reduction. We have studied the specific characters of all the species of Bogidiella, and their relationship with the taxonomy of the genus; those characters have been included in the tables (see table I) and discussed individually. We have concluded that the majority of the described species are valid; doubts are expressed on the B. glacialis S. Karaman, which is probably synonimous of B. albertimagni Hertzog and on B. ruffoi Birstein and Ljovuschkin, which is very similar to the B. lindbergi Ruffo. Considering current knowledge on the subject, it is not possible to recognize groups of similar species within the genus; as a matter of fact, the species known today show a range of diverging characters which are combined differently in different geographical areas. A table is shown to classify, using the more evident morphological characters, the different species of Bogidiella. From an ecological point of view the Bogidiella is divided into four different groups: a) mesopsammic marine species, b) litoral interstitial species, c) hyporheic interstitial species, d) troglobitic species. Two morphologically distinct types correspond to those four ecological groups: the mesopsammic interstitial type, which characterizes the first, second and third group, and the troglobitic type. From a biogeographical and evolutionary point of view, it seems evident that the Bogidiella come from the sea and their spreading to fresh water occurred in two different ways: the first was through the litoral interstitial habitat to the hyporrheic interstitial habitat, and the second by colonization, directly or indirectly, of large underground water basins. This population of the fresh water certainly occurred during different periods; as a matter of fact it is possible to find, even today, litoral interstitial species moving to the fresh water, while on the other hand species localized in regions corresponding to tertiary seas far from the actual coastal lines have been described (Central Asia, the Dead Sea, Danubian Region). With regard to this latter case, the transition to fresh water certainly occurred during the prequaternary period.
