Abstract

The paper considers new and little-known species of the genus Tetracanthella distributed in the Far East of Russia and in Japan. Sensillar chaetotaxy and labial palp, two less known morphological characters for the genus, are discussed. Two new species T.annulata sp. nov. and T.tardoki sp. nov. are described; T.manschurica Kutyreva, 1980 and T czernovae Kutyreva, 1980 are redescribed. For the latter species a lectotype and paralectotypes are designated. Remarks are provided for T.sylvatica Yosii, 1939. A second undescribed species is recorded for Japan. New records for T.orientalis Martynova, 1977 and T.sibirica Deharveng, 1987 are listed.
