The demography of Paronychiurus kimi, a dominant collembolan in paddy fields of Korea, was quantified for four treatments of the herbicide paraquat (0, 1.6, 16, 160 and 1600 microg/cm(2)) in a controlled environment using plaster-of-Paris as the test substrate. The survival rate of adults and the reproductive fitness of P. kimi were not affected by paraquat except at the highest dosage (1600 mi...

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 spec...

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. A...

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...

A checklist of Chinese Oligaphorurini is given. Two new Chinese species, Micraphorura changbaiensissp. n. and Oligaphorura pseudomontanasp. n., are described from Changbai Mountain Range. Micraphorura changbaiensis sp. n. has the same dorsal pseudocelli formula and number of papillae in Ant. III sensory organ as Micraphorura uralica, but they can be easily distinguished by number of chaetae in ...

Thalassaphorura is the most diverse genus in China so far. Three new species (T. guangdongensis sp. nov., T. xihuensis sp. nov. and T. linzhiensis sp. nov.) are reported from China. T. guangdongensis sp. nov. is characterized by its pso formulae (32/122/33343 dorsally and 11/000/01010 ventrally), 4+4 medial p-chaetae between posterior pso on head, 2+2 chaetae on Abd. I-III terga along axial lin...
