Achiasmy is a phenomenon whereby chiasma (“chromosomal cross–over”) formation is
absent during meiosis in one or both sexes. It is one of the strategies that have evolved to …

Simple Summary Pseudoscorpions are a wide-spread, but often-overlooked group of
animals. They are generally of small body size and rather homogeneous appearance. The …

Background/Objectives: Arachnids are a megadiverse arthropod group. The present study
investigated the chromosomes of pedipalpid tetrapulmonates (orders Amblypygi …

A taxonomic revision of the subgenus Chthonius (Ephippiochthonius) in the Iberian
Peninsula, Balearic Islands and Macaronesia is presented. New and previously insufficiently …

In this study, we investigated the mitotic and meiotic chromosomes of 11 Buthidae scorpion
species, belonging to three genera (Ananteris, Rhopalurus and Tityus), to obtain detailed …

Recent cytogenetic and genomic studies suggest that morphological and molecular
evolution is decoupled in the basal arachnid order Scorpiones. Extraordinary karyotype …

Mitotic and meiotic chromosomes of Tityus bahiensis were investigated using light (LM) and
transmission electron microscopy (TEM) to determine the chromosomal characteristics and …

The species of the subgenus Chthonius (Chthonius) CL Koch, 1843 displaying a sigmoid
fixed chelal finger from the Eastern Alps and the Carpathians, assigned to the informal …

We examined the distribution of genes for major ribosomal RNAs (rDNA) on holokinetic
chromosomes of 74 species belonging to 19 genera of scorpions from the family Buthidae …

The knowledge of cytogenetics in the harvestmen family Phalangiidae has been based on
taxa from the Northern Hemisphere. We performed cytogenetic analysis on Guruia africana …
