Two new species of the genus Leenurina Najt & Weiner, 1992 (Collembola, Neanuridae, Caputanurininae) from Primorskij Kraj (Russia)

Leenurina khualazasp. n. and Leenurina pomorskiisp. n., two new species from East Russia (Primorskij Kraj) are described. They are closely related to Leenurina jasii Najt & Weiner, 1992 from North Korea, from which they differ mainly in the number of tibiotarsal chaetae (19, 19, 18 in the new species versus 18, 18, 17 in Leenurina jasii), several chaetotaxic features and organization of dorsal granulation. The two new species may be separated by tertiary granulation (large areas fringed with large secondary granules in Leenurina pomorskii, small rounded or hexagonal areas with smaller secondary granules in Leenurina khualaza), coloration (light blue in Leenurina khualaza versus white in Leenurina pomorskii) and number of eyes (2+2 eyes in Leenurina khualaza versus 3+3 eyes in Leenurina pomorskii). An updated diagnosis of the genus Leenurina Najt & Weiner, 1992 and a key to species of Caputanurininae are given.     

A new species of Tullbergia (Collembola,Tullbergiidae) from Buenos Aires,Argentina

A new species of Tullbergia from Argentina is described and illustrated; it is differentiated from Tullbergia paranensis by the number of vesicles of postantennal organ, pseudocelli shape and its formulae and the number of dorsal sensilla on Ant. IV. In addition a key for the identification of the members of the family from Argentina is included.     

A new genus and species of Tullbergiidae (Collembola) from the Pacific Mexican coast

The new genus Mexicaphorura, and its type species Mexicaphorura guerrerensissp. n. are described from marine littoral sand. The new genus is similar to Sensilatullbergia Thibaud & Ndiaye, 2006 in having very big sensilla on sensorial organ of antennal segment III, but of different shape, the kind of postantennal organ, with simple vesicles in Mexicaphorura versus composed vesicles in Sensilatullbergia and formulae of the pseudocelli.     

Two new species of the tribe Hymenaphorurini Pomorski, 1996 (Collembola: Onychiuridae) from Korea

Two new species, Heteraphorura koreana sp. nov. and Psyllaphorura jirisana sp. nov., of the tribe Hymenaphorurini are described and illustrated based on materials from South Korea. Heteraphorura koreana sp. nov. belongs to the oriental species-group of the genus Heteraphorura, because of compound vesicles in the postantennal organ. This new species shares the same number of PAO with Heteraphorura pseudoseolagensis (Martynova, 1981) from Russia, but differs in pso dorsal formula and lateral teeth of claw. Psyllaphorura jirisana sp. nov. is similar to Psyllaphorura sensillifera.(Martynova, 1981) from the Russian Far East, but can be distinguished by shape of vesicles in PAO, dorsal s-chaetae on head and ratio AS/unguis. www.zoobank.org/urn:lsid:zoobank.org:pub:F854CBFD-06D0-4396-B8D9-62468B427111.

The first, Pseudachorutes solaris sp. nov., from Parque Estadual da Costa do Sol and from Parque Nacional da Restinga de Jurubatiba, differs from other species for having 34–50 vesicles in the postantennal organ, and the second, Friesea jurubatiba sp. nov. from Parque Nacional da Restinga de Jurubatiba, differs from other species for having 8 clavate chaetae in the abdominal segment VI.     

Syntomoza Amaliae,a New Species of Moth-Fly (Diptera,Psychodidae) from Nicaragua

A new species of Psychodidae, Syntomoza amaliae is described from Nicaragua and compared to all the type material of this genus. Besides head and wing structures, the subgenital plates provide taxonomic characters by which the ♀ ♀ can be determined. Drawings of the respective details are presented for 4 neotropical Syntomoza species.     

Phylogeny of the genus Palmanura (Collembola: Neanuridae)

In order to assess the phylogenetic structure of the springtail genus Palmanura, as well as to test the monophyly of the tribe Sensillanurini (Neanuridae: Neanurinae), a data matrix of morphological (chaetotactic and other) characters of members of this group was assembled and analysed in the light of Wagner parsimony. The data matrix included all the known members of the Neotropical genus Palmanura, plus representatives of Sensillanura and Americanura. Although not all the clades obtained were highly supported by bootstrap resampling, some structures were relatively constant under different approaches. Alternative analyses (unordered and ordered character states, rescaled weighting procedure) were applied. While alternative solutions were obtained, a number of structures were shared by the results irrespective of the method used. On this basis, the results suggest that some further reassessment is required to confirm formally the monophyly of the tribe Sensillanurini. The genera Palmanura and Americanura are mutually poly/paraphyletic; we thus suggest that Palmanura should be considered as a synonym of Americanura, although some character reassessment and more varied outgroup species may be necessary before a formal generic redefinition can be proposed. Finally, a comparison of the performance of the characters under Wagner parsimony analysis indicated that differences in the characters’ retention indexes are due not to the topological (tagmal) position of the traits involved, but to character coding: the characters describing quantitative features (generally numbers of setae) generally performed worse than other types of characters under parsimony. An updated list of the known members of the Sensillanurini (Collembola: Neanuridae: Neanurinae) is presented.

A taxonomic and cladistic analysis of the west European genus Monobella (Collembola, Neanuridae)

The genus Monobellu Cassagnau, 1979 (Collembola) is redefined. Four new species and one new subspecies are described from Pyrenees and Cevennes (France) on the basis of labrum morphology, tubercle arrangement on tergites and chaetotaxy of somites: Monobellu culvu sp. n., Monobellu eduphica sp. n., Monobellu grussei minor ssp. n., Monobellu juu sp. n., and Monobellu rousseti sp. n. The subspecies Monobellu grussei dubiu Deharveng, 1986 is reassigned to specific level. A key to the 14 species and subspecies of Monobellu is given. Except M. g. minor ssp. n. which is present in the Pyrenees and the Massif Central and the widespread M. g. grussei (Denis, 1923), all Monobellu species and subspecies are narrow endemics of the Pyrenean range; their distribution is mapped in details. A phylogenetic analysis is performed, taking into account the high level of polymorphism of some characters and the incomplete genetic isolation between certain subspecies, indicated in the field by the presence of narrow hybrid zones. Though obtained under different assumptions and constraints, the most parsimonious cladograms exhibit only slight differences, and the proposed phyletic reconstruction can be considered as robust. It adequately reflects the known distribution of the species in the Pyrenees, it confirms the monophyly of the species M. grussei and supports, in agreement with field distribution data, the idea that reticulate evolution might have occurred in this taxon. © The Norwegian Academy of Science and Letters

Sur la structure des chromosomes salivaires de Bilobella massoudi Cassagnau (Collembola: Neanuridae)

This work is a study of the giant salivary chromosomes of a Collembolan species of the family Neanuridae, Bilobella massoudi, recently discovered in North Jugoslavia. The salivary glands of this species have a great number of nuclei (from 100 to 140) containing polytene chromosomes which are very short and easy to spread. Their number is diploid (2n=14), with sometimes partial pairing of the homologues and they are characterized by the presence of broad heterochromatic zones. Chromosomes VI and VII produce ringlike nucleoli. Differences of structure are observed in these chromosomes according to ecological conditions which influence the animal's life.

Zusammenfassung Wir studieren in dieser Arbeit die Riesenchromosomen eines im Norden Yugoslaviens kürzlich entdeckten Collembolen der Neanuridae-Familie, Bilobella massoudi. Die Speicheldrüsen dieser Art besitzen zahlreiche Kerne (100–140), deren polytäne Chromosomen besonders kurz und leicht ausbreitbar sind. Ihre Zahl ist diploid (2n=14), und sie sind charakterisiert durch die Anwesenheit breiter, Scheiben- oder schärpenförmiger Zonen von negativem Heterochromatin. Zwei dieser Chromosomen (VI und VII) haben ringförmige Nukleolen.Strukturveränderungen wurden bei diesen Chromosomen bemerkt, je nach den ökologischen Bedingungen, denen diese Tiere unterworfen sind.

     

A new species of the genus Chlorencoelia (Helotiales) from China

Chlorencoelia collections from different regions of China were examined. A new species is discovered and named as C. macrospora. The most significant features to distinguish the new species from any other known species of the genus are its very large acsi and ascospores. Three of the five known species of the genus are found from China.     

New Chinese record of the genus Spinonychiurus (Collembola,Onychiuridae), with the description of a new species

A new collembolan species is described, Spinonychiurus sinensis sp. n., which has seven chaetae in the distal row of the tibiotarsi. It is placed in the genus Spinonychiurus due to two important characters: the two subsegments on Abd. III sternum and the absence of d0 on the head. This is the first report of the genus Spinonychiurus in China. The diagnosis of Spinonychiurus is broadened and the key to the world species is provided.
