摘要
Appendisotoma bisetosa Martynova, 1970、A. stebayevae (Grinbergs, 1962) 和 A. sibirica Stebayeva, 1985 是根据古北区的材料重新描述的。这三个物种的季节性周期形态是有区别的。冬季形态的巢穴上有顶端裂片、几丁质化的毛囊和较大的眼窝。腱膜、腱毛和色素也会受到周期变态的影响。Appendisotoma 种类的二形与 Proisotoma s. str.的几个种类相似。Appendisotoma monomorpha sp.
Taxonomy of the Cryptopygus complex. IV. Cyclomorphosis in three species of Appendisotoma and description of a new species from Kazakhstan (Collembola, Isotomidae)
Appendisotoma bisetosa Martynova, 1970, A. stebayevae (Grinbergs, 1962) and A. sibirica Stebayeva, 1985 are redescribed based on the material from Palaearctic region. Seasonal cyclomorphosis of the three species is distinguished. The winter form is armed with apical lobe on dens, chitinized furca and larger ocelli. Tenaculum, tenent hairs, and pigmentation can also be affected by cyclomorphosis. Dimorphism of species of Appendisotoma resembles that of several species of Proisotoma s. str. Appendisotoma monomorpha sp. nov. is described from Kazakhstan, taxonomic remarks are given to A. absoloni Rusek, 1966 and A. abiskoensis (Agrell, 1939).
