Two New Tanytarsus Species (Diptera: Chironomidae) from Brazil,with Reduced Median Volsella

The male adults Tanytarsus monospinosus sp. n. and Tanytarsus tumultuarius sp. n. from Brazil are described as new to science, and the species Tanytarsus abnormis Lehmann is transferred to Neostempellina Reiss. The species share the reduction of the median volsella, a genital feature well developed amongst most species of Tanytarsini. There are no obvious close relatives amongst previously described Tanytarsus species, and a thorough phylogenetic analysis including the immature stages will be necessary. However, because there are large differences between these two new species in most morphological characters, it can be assumed that they are not closely related, and the loss of the median volsella thus is unlikely to be a synapomorphy.     

New species of the genus Scaphocalanus (Calanoida: Scolecithricidae) from the Iskenderun Bay – northeastern Levantine Basin

A new calanoid copepod species Scaphocalanus emine n. sp. is described for the first time from the Iskenderun Bay, northeastern Levantine Basin. S. emine is similar to S. affinis (Sars, 1905) having both identical orientation of the posterolateral corners of the cephalothorax and a median crest on the forehead. The new species is also similar in some features to S. affinis in the structure of Re1P1- lacking the outer marginal spine and by the presence of the rounded apex on the distal internal margin. It differs from S. affinis as the median crest on the forehead is smaller and due to the presence of a rudimentary endopod furnished with an apical spine on the P5. Originality in construction of the P1 and P5 distinguish the new species from other Scaphocalanus species.     

Saccharomycopsis crataegensis,a new heterothallic yeast

A new species,Saccharomycopsis crataegensis, is described. The species is heterothallic and forms ellipsoidal ascospores with a single median longitudinal ledge. Strains of the species were isolated from grapes and hawthorne fruit obtained in Peoria, Illinois U.S.A. A comparison was made betweenS. crataegensis andS. vini, which included new strains of the latter species from hawthorne fruit.     

A new species of the genus <Emphasis Type="Italic">Stempellinella</Emphasis> (Diptera: Chironomidae) from Hiroshima,Japan

Stempellinella coronata sp. n. is described and illustrated based on male imagines. The new species can be separated from other Stempellinella species by its small size, low antennal ratio, high front leg ratio, minute frontal tubercles, a comparatively long median volsella, lacking median tergal setae, and lacking well-developed anal crests on the tergite IX. The generic diagnosis of Stempellinella is emended mainly to accommodate S. coronata. The species has so far been collected only from autumn to winter at pools in the unpolluted upper to mid reaches and was recorded first from the Ohta River system, Hiroshima, Japan.     

A new species of the genus Pergalumna Grandjean, 1936 from Iran (Acari: Oribatida: Galumnidae)

A new species of galumnid mite (Acari: Oribatida: Galumnidae), Pergalumna persica sp. n., is described from Fars province, southern Iran. The new species is characterised by a pointed rostrum, minute interlamellar setae, medium long, setiform sensilla, with finely barbed, slightly dilated head, complete dorsosejugal suture, large, nearly elongate-triangular areae porosae Aa, absence of median pore, and large body size.     

Notes on the bryophytes of the schistose valleys of western Crete,including Asterella africana new to Greece,and an assessment of the conservation status of Rhamphidium purpuratum and Jungermannia handelii

Atrichum laoshanense Y.-J.Yi &; S.He, a new species of Polytrichaceae from Laoshan mountain in Shandong Province, eastern China, is described and illustrated. The new species resembles, and is related to A. angustatum (Brid.) Bruch &; Schimp., but differs in the presence of stellately papillose median leaf cells, multicellular laminal teeth with well-defined outgrowths of pedestal cells on the distal dorsal lamina, and papillose stem epidermal cells. An updated key to species of Atrichum in China is presented.     

A new species of Astyanax Baird & Girard (Characiformes: Characidae) from the Rio Paraguaçu basin,Chapada Diamantina,Bahia, Brazil,with comments on bony hooks on all fins

A new species of Astyanax from the Rio Paraguaçu basin, Bahia, Brazil, is described. This new species is distinguished from its congeners known to occur in Brazilian drainages by the presence of small bony hooks on all fins of mature males. Furthermore, the new species can be diagnosed by its colour pattern, which consists of a unique vertically elongated humeral blotch, a conspicuous dark drop‐shaped horizontal blotch over the caudal peduncle, tapering anteriorly and not extending to the median caudal‐fin rays, and by the absence of a conspicuous broad dark midlateral stripe. The new species differs further by having the greatest body depth just anterior to the dorsal‐fin origin, 32–35 perforated scales in the lateral line and a reduced number of branched anal‐fin rays (16–20). Apparently, the new species does not fit into any species complex of Astyanax. The occurrence of bony hooks on all fins of Astyanax is discussed.     

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.     

Four new species of Halicyclops Norman, 1903 (Copepoda,Cyclopoida) from Brazil

Four new species of Halicyclops are described and figured from plankton samples of the brackish waters of Pomonga River, Sergipe State (NE Brazil). The ornamentation of the median apical setae of the furcal rami is proposed as useful diagnostic character for species distinction.
