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 phylogeneticrelationships with other New Guinean and Australian tibicinid genera. A key to the males and maps of distribution are presented.

Triturus marmoratus pygmaeus, a problematicsubspecies of the Marbled Newt from the southern part of the Iberian Peninsula, is redescribed using specimens collected in the “typical” area. Diagnostic external morphological features are provided to permit the accurate determination of the specimens belonging either to T. m. marmoratus or to T. m. pygmaeus. These diagnostic features were applied to individuals both from the field and from museum collections. The results indicate a larger distributional area for to T. m. pygmaeusto than was previously recognized. The distribution of to T. m. marmoratusto ranges over the northern half of the Iberian Peninsula and most of France; to T. m. pygmaeusto occupies the southwestern part of the Iberian Peninsula. The contact area between the two subspecies seemsto be located alongthe Central Range Mountains (Sistema Central) in Portugal and Spain. to T. m. marmoratusto extends southwards beyond this borderline in three areas: Serra da Estrela (Portugal), Sierra de Gata (Spain) and Sierra de Guadarrama (Spain). The only point at which to T. m. pygmaeusto reaches northwards beyond the Central System is near Puerto de Malagón (Madrid Province, Spain). No cases of strict sympatry, nor individuals with intermediate morphologicalfeatures have been observed. The results of an extensive cytogenetical analysis do not show any differences between to T. m. pygmaeusto and to T. m. marmoratusto . Interestingly, however, the to T. m. pygmaeusto populations from Doñana (Huelva Province, Spain) showed an exclusive, though little differentiated, C-banding pattern.

Neocyclops medius Herbst, 1955 and Neocyclops vicinus (Herbst, 1955) are redescribed from intertidal interstitial water of sandy beaches along the Brazilian coast. The male of N. vicinus is described for the first time.

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 are briefly discussed.

Two species of Roncus L. Koch, 1873 (Neobisiidae), new to science (R. ciobanmos n. sp. and R. dragobeten. sp.), and one species of Neobisium Chamberlin, 1930 [N. (N). biharicum Beier, 1939], collected in the Movile Cave, southern Dobrogea, Romania, have been described, diagnostic characters illustrated, and their geographic distribution analyzed. In addition, the description of Chthonius (Chthonius) monicae Boghean, 1989 (Chthoniidae), otherwise known only from two females, has been amended. The possible relationships of these species are discussed in view of the importance of some diagnostic characters and of the evolution of their cave habitat.

Recent collections in the south central U.S.A. have included three neotropical and one probably introduced species that are presently assigned to the cyclopoid copepod genus Mesocyclops. Mesocyclops longisetus var. curvatus Dussart, 1987, is reported from Louisiana, U.S.A., and Panama; published records of Mesocyclops longisetus (Thiébaud, 1914) sensu lato in the southern U.S.A. are reviewed. Mesocyclops reidae Petkovski, 1986, is reported from Mississippi, U.S.A., and Honduras. Mesocyclops ruttneri Kiefer, 1981, is redescribed from type specimens collected in Austria, and newly reported from Louisiana, Mississippi, China, Thailand, and Viet Nam. This species is considered to have been introduced from Asia into Austria and the U.S.A. Mesocyclops bernardi Petkovski, 1986, newlyrecorded from Louisiana and Mexico, is transferred to the genus Diacyclops.
The Cape Verde Cane Warbler Acrocephalus brevipennis was first described in 1866, and again in 1871 and 1883. These descriptions were all made after specimens from the same series. A type specimen was never designated and only one syntype from the original series can be traced today. The taxonomic history of the species is discussed and the single remaining syntype described. The present status and distribution of the species are briefly discussed.

The Niphargus transitivus group includes 12 groundwaterdwellingspecies. It is defined by an upright body position during locomotion,a small, stout body with short appendages, except for long coxae and dactyli, coxae V-VI equilobate or posterolobate, accessory flagellum subject to reduction, and the body endowed with adaptations for volvation (= ability to enroll into a ball).

Two species of anophthalmous, unpigmentedasellids have been found in springs and groundwaters of S.E. Siberia (Primorye region). Asellus (Asellus) primoryensis n. sp. is closelyrelated to the epigean species A. (A.) hilgendorfii Bovallius, 1886, as is the case for all stygobiont Asellus (Asellus) species previously known from the Japanese archipelago.
Sibirasellus parpurae n. g., n. sp. is closely related to the microphthalmous species Asellus dentifer Birstein & Levanidov, 1952 from the Ussuri Basin (Khor region), now type-species of the new genus Sibirasellus. These two species show several original characters: body covered by numerous cuticular squamulae, mandibular palp reduced (glabrous and 2-segmented), and coxopodites of pereopods reduced and coalescent with their sternites, pointing to certain affinities with the stygobiont Japanese genus Nipponasellus Matsumoto, 1962 and probably to the epigean species of the “latifrons” group of the genus Asellus, presently restricted to arctic Siberia and western Alaska.
The different asellid lines living in the Far East and Pacific North America are much more related with each other than with all other lines of the family.All these forms possess a copulatory system built on the “Asellus pattern”: Endopodite of 2nd male pleopod with a spur-shaped basal apophysis or “processus calcariformis”, an afferent spermaticopening with a labial spur or “processus cylindriformis”, and 2nd exopodite segment with a tergal or “catch lobe”. This phyletic system includes the genus Asellus Geoffroy, 1762 (the present status of which is discussed herein), its subgenera Asellus Dudich, 1925, Mesoasellus Birstein, 1951, and Phreatoasellus Matsumoto, 1962, and its related genera Calasellus Bowman, 1981, Nipponasellus Matsumoto, 1962, Uenasellus Matsumoto, 1962, and Sibirasellus n. g.

It is shown that the pinnacle of Max Weber’s scientific career was the organization and leadership of the Siboga Expedition to the former Netherlands East Indies (now Indonesia) in the years 1899—1900. Before that time, as Professor of both General and Special Zoology at the University of Amsterdam, he had devoted his research mainly to the anatomy of mammals, which resulted in the fundamental reference work Die Säugetiere published in first edition in 1904.
