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

Abstract

The paper is devoted to a taxonomic revision of the genus Sensillonychiurus Pomorski et Sveenkova, 2006. Five new species of this genus, i.e. S. mirus sp. n., S. taimyrensis sp. n., S. vegae sp. n., S. vitimicus sp. n., and S. amuricus sp. n., as well as three new species of the related genus Allonychiurus Yoshii, 1995, i.e. A. subvolinensis sp. n., A. elikonius sp. n., and A. unisetosus sp. 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 T. 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

A new species of <i>Ceratophysella</i> (Collembola: Hypogastruridae) from Japan, with notes on its DNA barcode and a key to Japanese species in the genus

“…Plurichaetosis is seen in some species and is well developed in Ceratophysella horrida (Yosii, 1960) and Ceratophysella pilosa (Yosii) (Babenko et al 1994;Yosii, 1960). We collected a new species with moderate plurichaetosis from the ascomata of Ciborinia camellia L. M. Kohn in Japan.…”

New Species and New Records of Springtails (Hexapoda: Collembola) from Caves in the Salem Plateau of Illinois, USA

“…Hypogastrura pannosa may be a junior synonym of H. assimilis (Babenko et al, 1994;Thibaud et al, 2004), but we follow previous workers (Fjellberg, 1985;Christiansen and Bellinger, 1998) in assigning the epithet pannosa to North American populations having a PAO with four papillate arms, mucronal lamella ending abruptly subapically, and Abd. 4 with sensillum-like seta p5.…”

“…C. brevis was originally described from surface habitats in Wyoming, but now it is also known from Alaska (Fjellberg, 1985) and from caves in Kentucky, California, and Indiana. In addition to the North American records, the species has been reported from Siberia (Babenko et al, 1994).…”
