Contribution to the knowledge of the genus Phyllopodopsyllus T. Scott (Copepoda,Harpacticoida) from Africa with description of two new species

Two new species of marine, sand-dwelling harpacticoids are described: Phyllopodopsyllus pallaresae n. sp. from Namibia, and P. hartmannorum n. sp. from Tanzania. The hitherto unknown male of P. xenus (Kunz) is described from Namibia. Further remarks are made on P. furciger Sars from Tanzania.Zwei neue sandbewohnende Harpacticoiden-Arten werden beschrieben: Phyllopodosyllus pallaresae n. sp. von Namibia und Phyllopodopsyllus hartmannorum n. sp. von Tansania. Außerdem wird das bisher unbekannte Männchen von Phyllopodopsyllus xenus (Kunz) von Namibia beschrieben. Morphologische Merkmale von Phyllopodopsyllus furciger Sars werden anhand eines Fundes von Tansania ergänzt.     

A new species ofThottea (Aristolochiaceae) from India

Thottea ponmudiana sp. nova from Kerala (India) can readily be distinguished from its closest allyTh. siliquosa and all the other known species of the genus by its yellow flowers with purple eyes, deeply lobed perianth with strongly reflexed margins, uniseriate stamens united in three bundles and strongly 4-angled, green, glabrescent fruits.     

Sporobolomyces inositophilus,a new species of ballistosporous yeast isolated from a dead leaf of Sasa sp. in Japan

A new species of ballistosporous yeast, Sporobolomyces inositophilus was isolated from a dead leaf of Sasa sp. collected at a mountain in Japan. This yeast is assumed to have a close relationship to Sporobolomyces singularis since it produces bilaterally symmetrical ballistospores and pale-coloured colonies and resembles Sporobolomyces singularis in these respects. These two species differ from typical species of Sporobolomyces and seem to constitute a natural taxonomic group.     

On Lecane tanganyikae new species (Rotifera: Monogononta, Lecanidae)

A new species of rotifer, Lecane tanganyikae n.sp., is described from the littoral of Lake Tanganyika and some water bodies in the plain of the Rusizi river near Lake Tanganyika, Bujumbura Province, Burundi. The affiliation of the new species, especially in relation to L. elsa Hauer, is discussed.     

Onychiurid species from Wanda Mountains in China,with descriptions of two new species (Collembola,Onychiuridae)

A checklist of onychiurid species from the Wanda Mountains in China is presented. Eighteen species belonging to twelve genera have been found, including two new species. Bionychiurus qinglongensissp. n. can be easily distinguished from other known species of the genus by the absence of pseudocelli on Th. I tergum and fewer number of vesicles in postantennal organ. Onychiurus heilongjiangensissp. n. is diagnosed by pseudocellar formulae as 32/133/33352 dorsally and 3/011/31120 ventrally, parapseudocellar formula as 0/000/111001+1^m, ratio of anal spine/unguis as 0.6, unguiculus without inner basal lamella, and male ventral organ absent.     

Two new species of the family Dicranophoridae (Rotifera, Ploima) from the littoral psammon, with notes on other brackish water rotifers in Denmark

The rotifer fauna has been investigated at three littoral brackish water localities in the Öresund, Denmark. Samples taken from plankton, periphyton and psammon yielded 14 rotifer species. Two of these are new to science and are described herein. Both species were found in psammon at the same locality. Erignatha longidentata n. sp. is characterised by having toes with swollen bases, convex outer margins and concave inner margins. The trophi have a pair of large subunci and relatively large unci. The other new species, Paradicranophorus wesenberglundi n. sp., is characterised by having two large red pigmented eyespots and large conical toes. The rami are lyrate, and intramallei and supramanubria are present in the mallei.     

A new species of Erebonectes (Copepoda,Calanoida) from marine caves on Caicos Islands,West Indies

The insects of a small and cold aestival stream in northern Sweden were studied from semiquantitative kick-samples taken every ten days throughout the ice-free season in 1987. The stream froze solid at least in some sections in some winters. In addition to dipterans that were only identified to the family level, five ephemeropteran, four plecopteran, 11 coleopteran (Dytiscidae), and four trichopteran (Limnephilidae) species were found. Baetis bundyae Lemkuhl, Heptagenia orbiticola Kluge (Ephemeroptera), Nemoura cinerea (Retzius) (Plecoptera), Hydroporus palustris (L), Agabus setulosus (J. Sahlberg) (Coleoptera), Anabolia concentrica (Zetterstedt), Limnephilus coenosus Curtis, and Micopterna sequax McLachlan (Trichoptera) were all common. Malaise trap data are given for Plecoptera. The two ephemeropteran species Heptagenia orbiticola and Metretopus alter Bengtsson, and the plecopteran species Nemoura viki Lillehammer were recorded for the first time in Sweden. The remarkable species composition was attributed to the harsh abiotic and poorly studied environment. We predicted that the larval composition of this stream was representative for aestival streams in northernmost Fennoscandia.     

A new species of Chironomus Meigen, 1803 (Diptera,Chironomidae) from the southeast of Brazil

The article describes the larva, pupa, adults and karyotype of Chironomus reissi, sp. n., which live on leaf detritus beds of small temporary waters in the southeast of Brazil. The species belongs to the pseudothummi cytocomplex with the chromosome arm combination AE, BF, CD, G.     

Cricotopus (Cricotopus) nevadensis sp. n. (Diptera,Chironomidae) from Sierra Nevada (southern Spain)

Male and female imagines, and pupal exuviae of Cricotopus (C.) nevadensis sp. n. are described. A discussion on the systematic position, a differential diagnosis and notes on the ecology of this new species are given.     

A mousebird (Aves: Coliiformes) from the Eocene of England

Summary The first fossil mousebird (Aves, Coliiformes) known from the Eocene of England is described. This taxon,Eocolius walkeri gen. n. sp. n., is assigned to the order Coliiformes (mousebirds) on the basis of a character of the proximal ulna (large cotyla dorsalis). The degree of similarity between the preserved elements ofEocolius and those of the other known fossil and Recent taxa further support this conclusion. At present, this new taxon is considered to occupy an unresolved position near to the base of the coliiform ingroup; the phylogenetic position ofEocolius cannot be resolved further owing to a lack of preservation of diagnostic characters.

Ein Mausvogel (Aves: Coliiformes) aus dem Eozän von England

Zusammenfassung Der erste fossile Mausvogel (Aves: Coliiformes) aus dem Eozän von England wird beschrieben. Dieses Taxon,Eocolius walkeri gen. n. sp. n., wird aufgrund von Merkmalen der proximalen Ulna (grosse Cotyla dorsalis) in die Ordnung Coliiformes gestellt. Darüber hinaus stützt der Grad der Üebereinstimmung zwischen den erhaltenen Skelettelementen vonEocolius und den anderen bekannten fossilen und rezenten Taxa diese Zuordnung. Zur Zeit nimmt dieses neue Taxon eine nicht näher aufgelöste Stellung an der Basis der Coliiformes ein. Das Fehlen diagnostischer Merkmale lässt keine sichere Zuordnung vonEocolius zu den ausgestorbenen Sandcoleidae oder den rezenten Coliidae zu.

     

Cyanospira rippkae and Cyanospira capsulata (gen. nov. and spp. nov.): new filamentous heterocystous cyanobacteria from Magadi lake (Kenya)

New filamentous heterocystous cyanobacteria were isolated from the alkaline soda lake Magadi in Kenya. The characteristics of the isolates are summarized and their taxonomic position discussed.Uniform attributes of the strains, grouped in two types, Mag II 702 and Mag I 504 are the following: helical structure of the trichomes, immotility, gas vacuolation, obligate autotrophy, nitrogen fixation under aerobic conditions, and closely similar fatty acid composition, including the uncommon cis-vaccenic acid.For these organisms the assignment to a new genus named Cyanospira is proposed with the species C. rippkae and C. capsulata, separated on the basis of structural, chemical and mean DNA-base composition. Type strains 702 and 504 will be deposited at the ATCC and PCC.     

A small loon and a new species of large owl from the Rupelian of Belgium (Aves: Gaviiformes,Strigiformes)

The early Oligocene Boom Formation in Belgium yielded many avian remains from the Rupelian unit-stratotype, most of which have remained unstudied so far. Here, I describe a small loon (Gaviiformes) and a new species of large owl (Strigiformes) that are represented by associated bones of a single individual each. The loon, of which wing and pectoral girdle bones are preserved, is assigned to Colymboides (?) metzleri, a species previously known from a partial skeleton from the Rupelian of Germany. The owl is based on a tarsometatarsus and distal tibiotarsus and described as a new species, Selenornis steendorpensis. It constitutes the most substantial fossil record of the taxon Selenornis, which was before known from a distal tibiotarsus from an unknown horizon of the Quercy fissure fillings in southwestern France. It is detailed that there are differences in the higher level taxonomic composition of the known early Oligocene avifaunas of northern and southern Europe, which may reflect true zoogeographic facts owing to a different climate and vegetation.     

Two new species of the genusAmblyeleotris (Pisces: Gobiidae) from the Ryukyu Islands,Japan

Two new shrimp-associated gobies,Amblyeleotris yanoi sp. nov. andA. masuii sp. nov. are described on the basis of specimens from Iriomote-jima Island and Okinawa-jima Islands, Okinawa Prefecture, Japan.A. yanoi is distinguished from other members of the genus by the combination of the following characters: 14 anal fin soft rays, 19 pectoral fin rays, 97–103 longitudinal scales, a candle flame-shaped marking on the caudal fin, a very low membrane connecting the pelvic fins and absence of a ventral frenum.A. masuii differs from all other congeners by having 92–97 longitudinal scales, the length of the interpelvic connecting membrane relative to the longest pelvic fin ray (0.43–0.66), black blotches on the sides of the chin, and blue spots on the opercle and preopercle.     

Anthessius kimjensis,a new species of Anthessiidae (Copepoda; Poecilostomatoida) associated with the pelecypod Solen grandis Dunker in Korea

Anthessius kimjensis n. sp. is described based on the specimens recovered from the pelecypod Solen grandis Dunker in the Korean coast of the Yellow Sea. The new species is distinguished from congeners by having a combination of characters: setal formula II, I, 5 on distal segment of leg 4 exopod, three terminal hooks on distal segment of second antenna, and ratio of length to width on caudal ramus (2.2:1).     

A new cave-dwelling and endemic species of the genus Pholeuonopsis (Coleoptera, Leiodidae) from Serbia

In the present study, a new species of a cavernicolous beetle is described from Serbia: Pholeuonopsis (Pholeuonopsis) zlatiborensis sp. n. (Leptodirini, Cholevinae, Leiodidae). All important taxonomic features have been thoroughly analyzed and illustrated. The new species probably belongs to an old phyletic lineage of mesogeid origin, like other known Pholeuonopsis species inhabiting cave and endogean habitats in the western part of the Balkan Peninsula. Therefore, the species is both relict and endemic inhabitant of cave habitats in Serbia.     

Anomoeodus pauciseriale n. sp. (Neopterygii, Pycnodontiformes) from the White Chalk Formation (Upper Cretaceous) of Sussex, South England

The new pycnodont fishAnomoeodus pauciseriale is described. The single specimen consists of associated but disarticulated skeletal remains including the paired prearticulars, some skull elements, remains of the pectoral girdle and the vertebral column. It comes from the White Chalk Formation (Upper Cretaceous) of East Sussex near Lewes, England. The precise stratigraphic age and locality are not known. The specific identification is based on characters of the prearticular dentitions because the other skeletal remains are not diagnostic. In contrast to other species ofAnomoeodus, the new species is characterised by a combination of rather short prearticular dentitions with only four tooth rows, a comparable low number of medial teeth, and the absence of intercalated teeth between tooth rows.      

Phenology and bathymetric distribution of the profundal chironomid fauna in Starnberger See (F.R. Germany)

Results of the first long-term investigation of the profundal chironomid fauna of Starnberger See, a prealpine lake are reported. Data are presented on the qualitative and quantitative composition of the chironomid fauna in the profundal of Starnberger See, on the spatial variation, and on the phenology of the dominant species, based on pupal occurrence and the seasonal distribution of larval instars. Twenty-five distinct chironomid taxa could be recorded in the profundal zone. Typical inhabitants of the profundal zone of Starnberger See are the larvae of the genus Micropsectra. The maximum abundance of Micropsectra larvae were found at 60 m with 5644 Ind.m⁻². Abundance, distribution and phenology of the dominant chironomid species are discussed in comparison with other lakes.
