“…Chromosomal heterozygosity originating from translocation, fusion or fission leads to the formation of trivalent, quadrivalent, or even multivalent chromosomal associations during meiosis I. Multivalent associations of more than four chromosomes are rare or underestimated, although they have been observed in certain plants [ 22 – 24 ], invertebrates [ 25 – 30 ] and vertebrates [ 31 – 36 ]. These multi-chromosomal associations form via rearrangements involving both autosomes and sex chromosomes or autosomes alone.…”

Scorpions represent an intriguing group of animals characterized by a high incidence of heterozygous chromosomal rearrangements. In this work, we examined six species of Tityus (Archaeotityus) from Brazilian fauna with a particular focus on elucidating the rearrangements responsible for the intraspecific variability of diploid number and the presence of long chromosomal chains in meiosis. To access any interpopulation diversity, we also studied individuals from four species representing distinct localities. Most species demonstrated intraspecific polymorphism in diploid number (2n = 19 and 2n = 20 in T. clathratus, T. mattogrossensis, and T. pusillus, 2n = 16, 2n = 17 and 2n = 18 in T. paraguayensis, and 2n = 16 and 2n = 24 in T. silvestris) and multi-chromosomal associations during meiosis I, which differed even among individuals with the same chromosome number. In some species, the heterozygous rearrangements were not fixed, resulting such as in Tityus clathatrus, in 11 different chromosomal configurations recognized within a same population. Based on meiotic chromosome behaviour, we suggested that independent rearrangements (fusion/fission and reciprocal translocations), occurring in different combinations, originated the multi-chromosomal chains. To evaluate the effects of these chromosome chains on meiotic segregation, we applied the chi-square test in metaphase II cells. The non-significant occurrence of aneuploid nuclei indicated that non-disjunction was negligible in specimens bearing heterozygous rearrangements. Finally, based on our analysis of many chromosome characteristics, e.g., holocentricity, achiasmate meiosis, endopolyploidy, ability to segregate heterosynaptic or unsynapsed chromosomes, ()n sequence located in terminal regions of rearranged chromosomes, we suggest that the maintenance of multi-chromosomal associations may be evolutionarily advantageous for these species.

The presence of a unique dorsointernal carina on the pedipalp chela distinguishes H. yaleensis sp. n. from all other Heterometrus species.Additional information is provided on the taxonomy and distribution of the genus Heterometrus in Sri Lanka, fully complemented with color photos of specimens of both sexes of the new species, as well as of their habitat. In addition to external morphology and hemispermatophore, we also describe the karyotype of H. yaleensis sp. n. (2n=99).
