| The sections Azorelloida, Neoandina, and Paramensia of Geranium, all of them from the Andes, are taxonomically revised. Fruits with the ‘seed ejection-type’ dispersal have been found in all species, which allows classifying them within subg. Geranium. The sections Azorelloida and Paramensia consist of one and two species respectively, while section Neoandina comprises 24 taxa. Prior to this revision, the stemless species of Geranium from the Andes have been considered to belong to sect. Andina. Geranium sessiliflorum (type of Geranium sect. Andina), however, should be included in sect. Chilensia. Therefore, recently a new sect. Neoandina has been described to include most of the sect. Andina species (Aedo, 2000). Diagnostic morphological features are... |

| Diaphorocera, a Saharo-Sindian genus belonging to the tribe Cerocomini, is revised and a new synonymy is proposed. A cladistic classification is proposed as well, on a set of adult morphological characters. The available bionomical records, both original and from literature, concerning phenology, elevation, habitat preference, and host plants, are summarised. Adult morphology of all species is described and figured, the catalogue of localities with maps of distribution is reported, and a biogeographical analysis is proposed. |

| The sea anemone species Isactinernus quadrilobatus Carlgren, 1918, and Synactinernus flavus Carlgren, 1918, which were described in new monotypic genera from few specimens collected in southern Japan, are synonymized, based on many more specimens from the South Pacific. As well as the geographic range, the depth range of this species has been extended to 110-700 m. The species had been distinguished primarily on whether the oral disc had four lobes (I. quadrilobatus) or eight (Synactinernus flavus) – we conclude their number is largely related to size of the animal. Other features that Carlgren had used to differentiate the genera (and species) are inconsistently present and do not correlate with lobe number. |

| The suborder Ingolfiellidea currently consists of 39 named species. An historical overview is presented and phylogenetic and biogeographic analyses are made. The result of the phylogenetic analysis suggests the definition of two new genera within an African freshwater group, namely Paraleleupia n. gen. and Proleleupia n. gen. Re-examination of a supposedly Italian relict species, Metaingolfiella mirabitis, with the aid of SEM techniques reveals a half-fusion of the head region with the first pereionite. The issue of the function of the ‘eyelobe’ is addressed and an explanation presented after examining with SEM such lobes in different species. Furthermore, additional descriptions are given based on the type-material of Metaingolfiella mirabilis,... |

| The pseudoscorpions of the genera Chthonius C.L. Koch, 1843 (Chthoniidae) and Roncus L. Koch, 1873 (Neobisiidae) from caves in Serbia, Yugoslavia, have been studied. Three new species, Chthonius (Globochthonius) purgo, Chthonius (Ephippiochthonius) kemza, and Roncus talason are described. A reanalysis of the type material of three subspecies of Chthonius and Roncus from Serbian caves has supported their elevation to full specific rank: Chthonius (Globochthonius) pancici Ćurčić, 1972, Roncus remesianensis Ćurčić, 1981, and R. timacensis Ćurčić, 1981. All species studied are considered endemics of the Balkan Peninsula. Diagnostic characters of the analysed taxa are thoroughly described or figured. Taxonomic interrelationships and geographical distribution... |

| Two new stygobiont amphipods are described from anchialine caves located in the Jaragua region (Pedernales Prov., Dominican Republic, Hispaniola). Ottenwalderia kymbalion gen. et sp. nov. is the first lysianassoid known to have penetrated into completely fresh waters, and the fourth colonizing hypogean habitats. Bahadzia jaraguensis sp. nov. is the second representative of this West Indian thalasso-stygobiont genus to be reported from fresh waters; it exhibits the most troglomorphic aspect (i.e. elongation of first antennae and sixth pereiopods) recorded for the genus. Its diagnosis is complemented with a key to the species of the genus Bahadzia. The in situ swimming behaviour of both taxa is briefly described. It is postulated that both amphipods share a... |

| The genus Guineapsaltria is erected for eight species, distributed in New Guinea and northeastern Queensland. Five species are transferred from the genus Baeturia Stål, 1866 and redescribed, viz. G. chinai (Blöte, 1960), G. flava (Goding & Froggatt, 1904), G. pallida (Blöte, 1960), G. stylata (Blöte, 1960), and G. viridula (Blöte, 1960), while three species are described as new to science (G. flaveola n. sp., G. pallidula n. sp., and G. pennyi n.sp.). G. flava is designated as the type species of the genus. Baeturia minuta Blöte, 1960 is synonymized with Guineapsaltria flava. The phylogeny of Guineapsaltria is discussed and some remarks are made on its phylogenetic relationships with other New Guinean and Australian tibicinid genera. A key to the males... |

| The allozyme data base of Arntzen & García-París (1995) on midwife toads (Alytes, Discoglossidae) is reanalysed considering each locus as a discrete character. The phylogeny thus inferred differs from the one obtained with genetic distances in the position of A. dickhilleni from the Betic region – it appears that its sister species is the widespread A. obstetricans, not the Mallorcan endemic A. muletensis. This phylogenetic hypothesis agrees with the taxonomic treatment of the genus based on morphology. A testable biogeographic hypothesis is proposed to account for the diversification of midwife toads in Iberia and the Balearics. The postulated underlying geological changes were the spread of inland saline lakes that divided Iberia (16 mY B.P.), the... |

| The sequestrate (truffle-like) basidiomycete genera Rossbeevera, Chamonixia, and Octaviania are closely related to the epigeous mushroom genera Leccinum and Leccinellum. In order to elucidate the properties and placement of several undescribed sequestrate taxa in the group and to reveal the evolutionary history of Rossbeevera and its allies, we conducted phylogenetic analyses based on three nuclear (ITS, nLSU, EF-1α) and two mitochondrial DNA loci (ATP6 and mtSSU) as well as precise morphological observations. Phylogenetic analyses of three nuclear loci suggest a complex evolutionary history with sequestrate fruiting bodies present in several clades, including a previously unrecognized sister clade to Rossbeevera. Here we propose a new sequestrate genus,... |

| Four previously unknown hypogean species of cyclopoid copepods were collected in cenotes and wells of the Yucatán Peninsula, Mexico. Diacyclops chakan sp. n. and D. puuc sp. n. differ from their congeners in combining 3-segmented swimming legs, 11-segmented antennules, and legs 1-4 endopodite segment 2 all with 2 setae. Species of Diacyclops rarely occur in tropical regions, and the Diacyclops described here are only the second and third species recorded from Mexico. The benthic D. puuc was found in the large underground reservoir of a cenote. Diacyclops chakan was encountered in such large open subterranean water basins, but more frequently and abundantly in wells. The two Mesocyclops species, M. chaci sp. n. and M. yutsil sp. n., most closely resemble... |

| Two monocelid species with simplex copulatory bulbs and postpharyngeal ovaries have been found in E. Australia. One of them presents a combination of characters not found in any of the known genera of the Monocelididae, and the new genus Acanthopseudomonocelis is proposed for it. The new genus is characterized by the presence of four stylet-bearing accessory organs and by an internal vagina; it is related to Pseudomonocelis. The other species, Pseudomonocelis schockaerti n. sp., is characterized by a complex bursa-vagina system, and by a highly muscular penial organ and male antrum. It is closely related to P. pardii Schockaert & Martens, 1987, from Somaliland. Two possibly additional species of the genus Pseudomonocelis, not found in a mature stage,... |
