Karyotype study on pseudoscorpions of the genus Lasiochernes Beier (Pseudoscorpiones, Chernetidae).
نویسندگان
چکیده
Karyotypes of the genus Lasiochernes (Pseudoscorpiones, Chernetidae) are studied for the first time. The diploid chromosome numbers of males were found to be 2n = 61 in L. pilosus, 2n = 69 in L. siculus and 2n = 73 in L. cretonatus. Karyotypes of all species mainly consist of biarmed chromosomes; the sex chromosome system is XO. Remarkably, the X chromosome displays partial (L. cretonatus), or even total (L. pilosus), negative heteropycnosis during the spermatogonial metaphase.

A multivariate study of differentiating characters between three European species of the genus Lasiochernes Beier, 1932 (Pseudoscorpiones, Chernetidae)
Morphological variation in three rarely collected European species of the genus Lasiochernes Beier, 1932 is thoroughly examined in the present study. Detailed descriptions of previously ignored morphological characters of Lasiochernes cretonatus Henderickx, 1998, Lasiochernes jonicus (Beier, 1929) and Lasiochernes pilosus (Ellingsen, 1910) are presented. The female of Lasiochernes cretonatus an...
متن کاملKaryotype diversity of pseudoscorpions of the genus Chthonius (Pseudoscorpiones, Chthoniidae) in the Alps
Pseudoscorpions are found in almost all terrestrial habitats. However, their uniform appearance presents a challenge for morphology-based taxonomy, which may underestimate the diversity of this order. We performed cytogenetic analyses on 11 pseudoscorpion species of the genus Chthonius C. L. Koch, 1843 from the Alps, including three subgenera: Chthonius (Chthonius) C. L. Koch, 1843, Chthonius (...
متن کاملKaryotype analysis and achiasmatic meiosis in pseudoscorpions of the family Chthoniidae (Arachnida: Pseudoscorpiones).
Karyotypes of pseudoscorpions (Arachnida, Pseudoscorpiones) are largely unknown. Here we describe for the first time karyotypes of the suborder Epiocheirata, represented by 9 European species of two genera of Chthoniidae, Chthonius and Mundochthonius. Diploid chromosome numbers of males range from 21 to 37. Karyotypes of both genera differ substantially. Acrocentric chromosomes predominate in k...

The pseudoscorpions Chthonius (Chthonius) carinthiacus Beier, 1951 and Chthonius (Ephippiochthonius) tuberculatus Hadži, 1937, are recorded for the first time from Slovakia. An illustrated description of these species is provided based on their morphological and morphometric characters. The descriptions of the species offer an update on the variability of their morphological and morphometric ch...
