Redescription of Chribellphoruraallanae (Christiansen & Bellinger, 1980) (Collembola, Onychiuridae), with comments on the systematic position of the genus.

ABSTRACT: Chribellphoruraallanae (Christiansen & Bellinger, 1980), a poorly known Nearctic springtail, is redescribed and important morphological characters are illustrated (Figs 1-7). The genus is characterized by the following characters: postantennal organ with one vesicle divided into five lobes, antennal segment IV with apical vesicle closely flanked by two papillae, sense organ of the third antennal segment with four papilla, four guard setae, two straight sensory clubs and two sensory rods, very similar in shape and length, labial palp of 0-type, abdominal sternum IV divided ventrally into two subsegments, furcal remnant as a finely granulated area with three rows of setae posteriorly, tibiotarsi with clavate setae in distal whorl and anal spines present. The taxonomic status of this Chribellphorura is also discussed.

A new species of Dicranocentrus (Collembola, Entomobryidae) from China with comments on the systematic position of the genus.

Project description:Dicranocentrus liuae sp. n. is described from the northern subtropical region of China. The new species is most similar to D. wangi Ma & Chen, 2007, but differs from it in the relatively shorter Ant. V, the 1+1 central macrochaetae on Abd. III, the number of chaetae on tenaculum, and the absence of dental spines. The systematic position of Dicranocentrus is also discussed. Present evidence, particularly S-chaetotaxy, indicates that the genus is closer to Heteromurus than to the unscaled species of Orchesella and Orchesellides.

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

Project description: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.

Redefinition of the genus Allonychiurus Yoshii, 1995 (Collembola, Onychiuridae) with description of a new species from China.

Project description:In this paper, we describe a new species of the genus Allonychiurus Yoshii, 1995, characterized by the presence of an apical swelling on the fourth antennal segment as well as a combination of chaetotaxic and pseudocellar characters. The genus Allonychiurus is redefined. Four of its species are considered as incertae sedis: Allonychiurus michelbacheri (Bagnall, 1948), Allonychiurus spinosus (Bagnall, 1949), Allonychiurus caprariae (Dallai, 1969) and Allonychiurus sensitivus (Handschin, 1928). The three species Allonychiurus borensis (Beruete, Arbea & Jordana, 1994), Allonychiurus sensilatus (Thibaud & Massoud, 1979) and Allonychiurus vandeli (Cassagnau, 1960) are removed from Allonychiurus and placed in Micronychiurus Bagnall, 1949, Thalassaphorura Bagnall, 1949 and Spinonychiurus Weiner, 1996 respectively. The synonymy of Thibaudichiurus Weiner, 1996 with Allonychiurus is rejected and Allonychiurus foliatus (Rusek, 1967) and Allonychiurus mariangeae (Thibaud & Lee, 1994) are re-allocated to Thibaudichiurus. List and identification key to the world species of the genus are given.

Collembola of the genus Protaphorura Absolon, 1901 (Onychiuridae) in the Eastern Palearctic: morphology, distribution, identification key.

Project description:Seven new species, Protaphorura jernikasp. n., Protaphorura absconditasp. n., Protaphorura tuvinicasp. n., Protaphorura vasilinaesp. n., Protaphorura sayanicasp. n., Protaphorura oligopseudocellatasp. n. and Protaphorura nikolaisp. n. from different habitats of the southern Siberia and Far East of Russia, are described. Protaphorura ombrophila (Stach, 1960) is redescribed based on the type specimens. These species differ one from other and from all known species by dorsal and ventral pseudocellar formulae, number of pseudocelli on subcoxae 1 of legs I-III, parapseudocellar formula, chaetotaxy of body, structure of claw, size of postantennal organ and body length. Geographical distribution of all known Protaphorura species of Eastern Palearctic was analysed and an identification key to 50 species was provided.

Broadening the definition of the genus Thalassaphorura Bagnall, 1949 (Collembola, Onychiuridae) with a new aberrant species from China.

Project description:A new species belonging to the tribe Thalassaphorurini, Thalassaphorura problematica sp. n., is described from Northeast China. The new species is closest to the large genus Thalassaphorura by its simple vesicles in PAO and its furcal rudiment, but it does not fit the definition of the genus by the absence of chaeta d0 on head, the number of chaetae in the distal whorl of tibiotarsi and the labium type. We discuss the relative weakness of these last characters at generic level, which lead us to assign the new species to Thalassaphorura instead of erecting a new genus. The diagnosis of Thalassaphorura is broadened accordingly.

Two new species of Hymenaphorura Bagnall, 1948 (Collembola, Onychiuridae) from Romania and an updated key to the genus.

Project description:Two new species of the genus Hymenaphorura from Romania, H. urbana sp. nov. and H. kalindera sp. nov., are described and illustrated. Hymenaphorura urbana has a postantennal organ (PAO) with 13-15 simple vesicles, abdominal terga I-III with subequal setae p2 and p3, abdominal tergum V granular area with 3+3 distinct, long macrosetae, and H. kalindera sp. nov. has PAO with 9-12 simple vesicles, one border seta, abdominal terga I-III with setae p2 slightly longer than setae p3, abdominal tergum V granular area with 4+4 distinct macrosetae. Remarks on H. subsimilis Bagnall, 1948 are given. An updated key for the world distributed species of Hymenaphorura is presented.

New Palaearctic species of the tribe Thalassaphorurini Pomorski, 1998 (Collembola, Onychiuridae).

Project description:The paper is devoted to a taxonomic revision of the genus Sensillonychiurus Pomorski & Sveenkova, 2006. Five new species of this genus, i.e. Sensillonychiurus mirussp. n., Sensillonychiurus taimyrensissp. n., Sensillonychiurus vegaesp. n., Sensillonychiurus vitimicussp. n., and Sensillonychiurus amuricussp. n., as well as three new species of the related genus Allonychiurus Yoshii, 1995, i.e. Allonychiurus subvolinensissp. n., Allonychiurus elikoniussp. n., and Allonychiurus unisetosussp. n. are being described from various regions of Eurasia. The diagnoses of both genera are amended to include described species. Two genera, Tantulonychiurus Pomorski, 1996 and Thibaudichiurus Weiner, 1996, are treated as junior synonyms of the genus Allonychiurus. Agraphorura eisi (Rusek, 1976) is transferred to Sensillonychiurus; Tantulonychiurus volinensis (Szeptycki, 1964) and Tantulonychiurus asiaticus Babenko, 2007 to Allonychiurus. A review of morphological peculiarities of Sensillonychiurus is performed, comparisons with the other genera of Thalassaphorurini given, and a key to the known species provided.

The complete mitochondrial genome of Orthonychiurus folsomi (Collembola: Onychiuridae).

Project description:The complete mitochondrial genome of Orthonychiurus folsomi (Schäffer 1900) was sequenced, assembled, and annotated. The mitochondrial genome of O. folsomi has a length of 15,283bp and comprises 13 protein-coding genes, 22 tRNA genes, and two rRNA genes. Two tRNA genes trnS(uga) and trnQ have changed position. A phylogenetic tree of Onychiuridae species showed the polyphyly of this family.

Project description:A new species, Uralaphorura liangshuiensissp. n., has been reported from Xiao Hinggan Mountains (northeast China). The new species is unique in having the pso formulae as 32/133/33332 dorsally and 0/000/0001(0) ventrally, and the ventral psx formula as 3/000/221000. A key to all known species of the genus is given.

A new cave-dwelling species of Deuteraphorura from northern Italy (Collembola, Onychiuridae).

Project description:A new cave-dwelling species, Deuteraphorura pierolucciisp. n., is described from northern Italy. The size of adult specimens, number, and distribution of dorsal and ventral pseudocelli, and number of compound vesicles of the post antennal organ were used to distinguish it among other congeneric species.
