Sibiracanthella and Sahacanthella new genera of Anurophorinae (Collembola, Isotomidae) with anal spines from continental

Abstract

Two new genera and new species (Sibiracanthella nuda, Sibiracanthella sohondo and Sahacanthella kele) are described from the arid regions of continental Asia. Sibiracanthella is characterized by the presence of four anal spines, apical bulb on the fourth antennal segment and smooth integument. Sahacanthella differs from it by the presence of two anal spines, specific protuberance and reticulated integument. A key for identification of the holarctic genera of Anurophorinae with anal spines is given.
