A survey of the underground waters of Southeastern Spain has established the presence of anophtalmous and unpigmented Asellids in many localities. Six new endemic species Proasellus are named and defined by the structures of their sexual pleopods: P. bellesi n.sp. (Rio Guadalhorce drainage, Province of Málaga); P. escolai n.sp. (Rio Genil, Granada); P. espanoli n.sp. (Rio Fardes, Granada); P. lagari n.sp. (Rio Argos, Murcia) and P. margalefi n.sp. (Rio Turia, Valencia). These forms are related to the oculated and pigmented species Proasellus meridianus (Racovitza, 1919). Four hypogean species were previously known from these regions: P. solanasi Henry & Magniez (Rio Guadiaro drainage, Málaga); P. jaloniacus Henry & Magniez (Rio Jalon, Alicante); P....

Présence de synasellus (Crustacea, Isopoda, Asellidae, Stygobies) dans la Province de Huelva (Espagne)

Ano: 1982

Descriptions are given of two new phreatobitic species of the genus Synasellus Braga, 1944, from Huelva Province, Andalusia, Spain. A check-list is presented of the 32 known species of the genus with their type-localities. A primary homonymy is corrected: Synasellus bragai Henry & Magniez, 1987 = Synasellus bragaianus nom. nov. Notes are made on the ecology, biogeography and evolution of the Asellidae of the Iberian peninsula.

Numerous samples of oculate Asellus from eastern Siberia and the Japanese Islands, one from southern China, and one from Alaska, have been studied. The epigean fresh waters of this large Asiatic region generally harbour populations identified as Asellus (Asellus) hilgendorfii Bovallius, 1886, or some of its geographical forms previously considered as species, subspecies, or not yet named. The “hilgendorfii” complex seems to possess the dimension of a superspecies. A new pigmented-oculate species, Asellus (Asellus) levanidovorum is sympatric with A. (A.) hilgendorfii in the lake Bolon region (lower part of the Amur River basin) and is present also in the Sakhalin and Kunashir Islands. Its copulatory organ (endopodite of male 2nd pleopod) shows a large...

Asellus aquaticus is present in 19 of about 100 Turkish groundwater stations prospected during biospeleological explorations. All specimens of these stygophilic populations remain oculate, even though their integumental pigmentation is more or less reduced. Proasellus lykaonicus Argano & Pesce, 1978 has been found again in a second cave, nearby the type locality. A large and endemic, stygobiont species, Proasellus pisidicus n. sp., from phreatic groundwater, Vilâyet Burdur, and the minute Proasellus pamphylicus n. sp. from interstitial waters of the eastern part of Vilâyet Antalya are described. The stygobiont proasellids of Asia Minor, P. lykaonicus and P. pisidicus n. sp. belong to the same phylogenetic strain of Proasellus as those of Transcaucasia,...

Asellus (Asellus) monticola monticola Birstein, 1932 has been found in a spring in the extreme NW of Iran. Amplifications of the original description of this valid species, which is clearly distinct from A. aquaticus, are given. Contrary to A. aquaticus, A. monticola appears to be strongly endemic and stenotopic; its settlement may have taken place prior to the expansion of A. aquaticus across Europe. Some reflections on the taxonomy and biogeography of the Asellidae of the Transcaucasian region are included.

Magniez, Guy.

The entire family Stenasellidae Dudich, 1924 is composed of ancient stygobitic strains sharing a thalassoid and thermophilic origin. Its presence in Europe is dependent on two factors, the permanent existence of emerged continental shields during long geological periods (at least Tertiary + Quaternary), and its conservation in favourable areas during the different glacial crises. The iberian peninsula seems to have been the most suitable european region for the survival of this stygofauna. Some 119 samples from 116 different localities -scattered over 19 Spanish provinces- have been studied. All aquitanian and iberian stenasellids belong to the traditional genus Stenasellus Dollfus, 1897. We must notice that the stenasellids seem to be absent in the betic...

Samples collected in underground waters of Spain by Ine Meijers and Jos Notenboom demonstrated the presence of some oculated asellids previously known: Proasellus coiffaiti, P. coxalis, and P. meridianus, and also four new stygophilous species, more or less depigmented, with different stages of regression of the ocular system: P. beticus n. sp., P. ortizi n. sp., P. aragonensis n. sp., and P. ebrensis n. sp. These forms represent relict populations of ancient epigean species. The anophthalmous species of the Aquitanian Basin, Pyrenees, and Iberian Peninsula are more closely related to P. beticus and P. ortizi than to the Recent epigean species P. coxalis and P. meridianus.

Afonso, Odette; Henry, Jean-Paul; Magniez, Guy.

From now on, the genus Bragasellus Henry & Magniez, 1968 includes 2 oculated and 17 stygobiotic species. As a natural and monophyletic taxonomic unit, we consider it a good genus. Its original area corresponds to the north-west quarter of the Iberian Peninsula. Secondarily, this area has extended eastward, using mainly the alluvial channels of hydrographic systems (Ríos Douro + Ebro and tributaries), finally reaching the underground waters of several Mediterranean rivers. This active expansion is exclusively due to the migration of two stygobiotic sibling species: B. lagari Henry & Magniez, 1973 towards the high basin of the Río Tajo, then downstream to the basins of the Ríos Jucar and Turia (Prov. Valencia); and B. lagarioides n. sp., downstream...
