Contribution to the knowledge on spring fauna in the Bela Reca river valley (Romania)., 1965,

Capuse Iosif, Motas Constantin
After an introduction, comprising a historical summary on the researches on well fauna, a description of the study area in which 13 water wells have been investigated is given. The authors explain the adopted working method and indicate the physical and chemical characteristics of the waters (temperature, pH, alkalinity, hardness, O2-content, fixed residuum, suspended matter, N2O5, P2O5, NaC1, Ca, Fe). The fauna of the wells of Mehadia (see systematic part) is composed of 34 species: 1 Triclade, 3 Oligochaeta, 2 Gastropods, 5 Cladocera, 1 Ostracod, 3 Copepods, 4 Isopods, 2 Amphipods, 1 Halacarida, 1 Collembola, empty puppies of a Trichoptera, 2 Coleoptera and 8 Diptera (larves and nympha). Among these species 15% can be considered phreatobionts: a blind Triclade (not identified), Candona eremita Vejd., Asellus (Proasellus) danubialis Lt. & M. Codr., Asellus (Proasellus) elegans Lt. & M. Codr., Niphargus jovanovici bajuvaricus Schell. and Niphargopsis trispinosus Dancau & Capuse. The remaining 28 species, counting for 85%, belong to the phreatoxenes. It is worth to mention that Vejdovsky (1882) in wells near Prague, Jaworowski (1895) in wells of Cracovia and of Lwov, Moniez (1888, 1889) in wells in North-East France and Chappuis (1922) in those close to Bale, have found a much smaller proportion of phreatobe forma (e.g. Chappuis 2%).

Contribution to the study of the biology of Asellus cavaticus Leydig (preliminary note)., 1965,

Henry Jean Paul
The cavernicole asellid Asellus cavaticus Leydig has been reared in our laboratory for more than twenty months, permitting us to give some data on the sexual cycle of this species. Females provided with brood pouches seem to be more numerous in the spring, as is the case with the subterranean amphipod Niphargus virei Chevreux. The average length of the incubation period seems much shorter than that of other troglobitic species such as Niphargus virei Chevreux or Caecosphaeroma burgundum Dollfus, so that the life cycle of our species is nearer to that of epigean Asellus. The number of young per brood appears to be related to the length of the female, as is suggested by our observations on 52 ovigerous females, but there must be other factors which influence this quantity. The comparison between our observations and those made on the North American cavernicole Asellus tridentatus Hungerford shows that the sexual biology of these two species is apparently quite different.

The author describes a new species, Niphargus toplicensis n. sp., of the spring Toplitzata near the village of Mussomischta (district of Goze Delcev). N. toplicensis n. sp. Is closely related to N. aquilex moldacicus Dobreanu, Manolache and Puscariu, 1953, N. smederevanus Karaman, 1950, N. anatolicus Karaman, 1950, N. pancici Karaman, 1929, N. pancici clkanovi Karaman, 1959 but differs for several characters (a greater number of setae on the internal lobe of maxilla I, the coxal plates longer than their width, different armour of the telson and of the uropods I etc.).

The Crustaceans of the reservoir of the Fontaine des Suisses at Dijon., 1966,

Dussart Bernard, Graf Franois, Husson Roger
Inventory of the Crustaceans collected in the basin of the Fonatine des Suisses at Dijon. The Copepoda are represented by 5 species: Macrocyclops albidits, Eucyclops serrulatus in two slightly different forms, Eucyclops serrulatus var. mihi, Acanthocyclops venustus, Acanthocyclops vernalis and Acanthocyclops robustus. The coexistence of these two last forms in this very tiny environment makes it probable that we have here to do with two distinct species. A determination key is given for the Genus Acanthocyclops. Amphipoda are represented by Niphargus virei and especially Niphargus kochianus kochianus of which more than 100 samples have been collected. Of this last small species some considerations regarding geography, the laying of eggs, sexual dimorphism and closely related species are also given.

A new genus and species of freshwater Gammaridae (Amphipoda) from subterranean waters of Western Australia is described, Hurleya kalamundae n. g. n. sp. The genus apparently represents an aberrant line of the Crangonyx group of Gammaridae.

The Mammoth Cave system includes more than 175 kilometers of explored passages in Mammoth Cave National Park, Kentucky. Although biologists have explored the caves intermittently since 1822, the inventory of living organisms in the system is still incomplete. The present study lists approximately 200 species of animals, 67 species of algae, 27 species of fungi, and 7 species of twilight-zone bryophytes. The fauna is composed of 22% troglobites, 36% troglophiles, 22% trogloxenes, and 20% accidentals, and includes protozoans, sponges, triclads, nematodes, nematomorphs, rotifers, oligochaetes, gastropods, cladocerans, copepods, ostracods, isopods, amphipods, decapods, pseudoscorpions, opilionids, spiders, mites and ticks, tardigrades, millipedes, centipedes, collembolans, diplurans, thysanurans, cave crickets, hemipterans, psocids, moths, flies, fleas, beetles, fishes, amphibians, birds, and mammals. The Mammoth Cave community has evolved throughout the Pleistocene concomitantly with development of the cave system. The troglobitic fauna is derived from 4 sources: (1) troglobite speciation in situ in the system itself; (2) dispersal along a north Pennyroyal plateau corridor; (3) dispersal along a south Pennyroyal plateau corridor; and (4) dispersal across the southwest slope of the Cumberland saddle merokarst.

The new subspecies, Niphargus jovanovici burgundus n.subsp., is described from a well at Dijon, France. The principal diagnostic characters are given and a comparison with other known subspecies of N. jovanovici is made. Two groups of subspecies in N. jovanovici are distinguished and some critical remarks on probable affinities of N. jovanovici with other species of Niphargus are made.

Holsinger John R.
The systematics of the North American, subterranean amphipod genus Allocrangonyx are revised and two species are recognized; A. pellucidus (Mackin) and A. hubrichti, new species. Allocrangonyx is critically compared with the European genus Niphargus and several endemic North American genera of the Crangonyx group. Because of its unique morphological position, Allocrangonyx is removed from the Crangonyx group and placed in the newly designated AlIocrangonyx group. Some factors believed to have influenced speciation within the genus are discussed in some detail.

A new eyeless Amphipod Crustacea 5 mm long was found in Himis-d Cave in Tokushima Prefecture, Shikoku. The inner ramus of its third uropod is nearly as long as the unijointed outer ramus. The accessory flagellum of the first antenna consists only of a single joint. The first maxilla is distinctive in its small palp which does not extend beyond the apical margin of the outer plate and bears only an apical seta. In these characteristic features the present form is different from any known species of the genera of the Crangonyx and Hadzia groups and seems to belong to a new species, on the basis of which the new genus Awacaris is created.
