Five new species of the genus Bogidiella Hertzog (Crustacea, Amphipoda, Gammaridae) are described from subterranean waters of Mexico and Guatemala. They have been collected during the biospeleological researches in southern Mexico and Guatemala (1973, 1975) promoted and financed by the Accademia Nazionale dei Lincei.
B. orchestipes n. sp. (Mexico, Chiapas, well at S. Cristobal de las Casas) is a medium sized (3-4 mm) phreatic species, with lenticular organs on the pereopods III-VI, related to B. holsingeri Ruffo and Vigna, 1973, in the shape of the gnathopods (sinuate palmar edge and a single palmar spine), pleopods, telson and mouth appendages (maxilla I with pluridentate spines on the outer lobe, maxilla II with elongated lobes, maxillipeds with second article of the palpus broadened), but easily distinguishable for the elongated body, with mesosomites longer than their height, coxal plates distanced, the posterior edge of the basis of gnathopods with 3 long setae, the carpus of the pereopod VII strongly dilated, the uropod I differentiated in the male, with 2 rasp-like spines on the outer ramus.
B. pasquinii n. sp. (Guatemala, Huehuetenango, S. Eulalia, Cueva de los Resadores) is a cave-dwelling species, with lenticular organs on the pereopods III-VI, very similar to B. holsingeri Ruffo and Vigna, 1973, in the shape of buccal appendages, gnathopods, pleopods and telson, but distinguishable for the smaller size (2,2-2,8 mm), the posterior edge of the basis of gnathopods with 3 long setae, the dactylus of pereopods III-IV longer than half the length of propodus, with elongated claw, and especially for the shape of the uropod I of the male, with the outer ramus small and at right angle with the inner one, provided with a very long basal spine, curved at semicircle and denticulate at the end.
B. vomeroi n. sp. (Mexico, Chiapas, Sitala, Cueva de Chanchaniptic) is a small sized (2,2-2,6 mm) cave-dwelling species, similar to B. holsingeri Ruffo and Vigna, 1973, for lenticular organs, buccal appendages, gnathopods, pleopods and telson, but with the uropod I not differentiated in the male; the gnathopods I and II have similar propodites, and only 1 long seta on the posterior edge of the basis; pereopod VII has merus and carpus dilated. We refer, uncertainly, to the last species also two small (2 mm) femal specimens found in another cave (Mexico, Chiapas, El Porvenir, Sumidero de Canada) from an isolated karst area at high altitude of southern Chiapas.
B. niphargoides n. sp. (Mexico, Oaxaca, well at Etla) is a medium sized (4 mm) phreatic species, not related to the previously known species, with mesosomites higher than their length, large coxal plates, small lenticular organs on the basis of the pereopods III-VI; maxillae I with pluridentate spines on the outer lobe; antennae I longer than half the total length; gnathopods with 3-4 long setae on the posterior edge of the basis and with large, ovoidal propodus; palmar edge with a great number of spines; pereopods slender and elongated; pleopods and uropods not differentiated in the male.
В. michaelae n. sp. (Mexico, Oaxaca, well at Etla) is another phreatic species of medium size (3 mm), not related to the previously known species; male unknown; without lenticular organs on the pereopods; maxillae I with pluridentate comb-like spines on the outer lobe; gnathopods with only 1 long seta on the posterior edge of the basis and 1 palmar spine; carpus of gnathopod II long as propodus, this one small, subrectangular, with palmar edge short and little inclinated; pereopods stout, the VII with merus, carpus and propodus dilated; uropod I with the outer ramus shorter than inner, uropod III with dilated rami; telson distally not incised.
The previously known species from Mexico, B. tabascensis Villalobos, 1961; B. sbordonii Ruffo and Vigna, 1973, and B. arganoi Ruffo and Vigna, 1973, have been found in some new localities; all these show some differences from the typical populations. B. tabascensis from Chiapas (Ocosingo, Cueva de Chital n. 2) differs from specimens of Tabasco for the shape of the differentiated spines of the pleopods I and II of the male and for the slender pleopods; B. sbordonii from Central Chiapas (S. Cristobal, Cueva de la Planta n. 3 and Altamirano, Cueva de los Chivos) differs from the typical specimens from the area near Ocozocoautla in the shape of the differentiated spines of the pleopod I of the male and in the not differentiated spine of the pleopod II; B. arganoi from the well at Etla (collected together B. niphargoides n. sp. and B. michaelae n. sp.) has some characters different from the only one type specimen from Paraje Nuevo (Veracruz, Cordoba). These specimens are described and figured. Presumably they may belong to different subspecies; at present we do not refer them to any fixed taxonomical status, for lack of knowledge in the geographical variation of these species.
Other single specimens of the genus Bogidiella from phreatic waters of wells in Oaxaca Lambityeco), Puebla (Tehuacan) and Campeche (Campeche), not suitable for complete study, lacking in appendages, are also listed.
In the last part of this work, the status and the relationships of the Central American Bogidiella are discussed; as far as our present knowledge, two groups of species could be established: the tabascensis-sbordonii-group (without lenticular organs and with sexual dimorphism in differentiated spines on pleopods of the male and the holsingeri-pasquinii-orchestipes-vomeroi-group (with lenticular organs on pereopods III-V I, palmar edge sinuate and only I palmar spine on propodus of gnathopods, and with sexual dimorphism in the uropod I of the male, however vomeroi lacks in this character). В. arganoi may be related to the last group, in sexual dimorphism in the uropod I of the male and in similar shape of mouth appendages etc.; on the contrary, B. niphargoides and B. michaelae are well isolated species among the Central American ones.

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.

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.
