“…The only references to sex chromosomes in scorpions were in the mitosis of Leiurus quinquestriatus (Ehrenberg 1828) (Buthidae) and Nebo hierichonticus (Simon 1872) (Scorpionidae) [11, 12], where the presence of an XY/XX system is assumed but without any evidence to support it, and in the meiosis of Tityus bahiensis (Perty 1833) [13]. …”

Scorpions of the genus Tityus show holokinetic chromosomes, achiasmatic male meiosis and an absence of heteromorphic sex chromosomes, like all Buthidae. In this work, we analysed the meiotic behaviour and chromosome rearrangements of a population of the scorpion Tityus confluens, characterising the cytotypes of males, females and embryos with different cytogenetic techniques. This revealed that all the females were structural homozygotes, while all the males were structural heterozygotes for different chromosome rearrangements. Four different cytotypes were described in males, which differed in chromosome number (2n = 5 and 2n = 6) and meiotic multivalent configurations (chains of four, five and six chromosomes). Based on a detailed mitotic and meiotic analysis, we propose a sequence of chromosome rearrangements that could give rise to each cytotype and in which fusions have played a major role. Based on the comparison of males, females and a brood of embryos, we also propose that the presence of multivalents in males and homologous pairs in females could be associated with the presence of cryptic sex chromosomes, with the male being the heterogametic sex. We propose that the ancestral karyotype of this species could have had homomorphic XY/XX (male/female) sex chromosomes and a fusion could have occurred between the Y chromosome and an autosome.

“…Although there are several faunistic and taxonomic studies on the genus Hottentotta, there is a paucity of cytogenetic studies. Chromosomal data are known for only three of the total of 51 currently recognized species of the genus Hottentotta species (10), were included in cytogenetic studies (11)(12)(13)(14)(15). Hottentotta tamulus species possesses 2n=22, 24 or 20-28 chromosomes forming a continuous series (12)(13)(14).…”

Objective: The species Hottentotta saulcyi is widely distributed from Mardin to Hakkari while the distribution of Buthacus macrocentrus is limited to the south-east of Turkey (only Şanlıurfa). The aim of this study is to analyze the cytogenetic structure of Hottentotta saulcyi and Buthacus macrocentrus. Materials and Methods:The specimens were collected during the night from Şırnak and Şanlıurfa using a UV lamp. The male Hottentotta saulcyi were collected from Şırnak and male and female Buthacus macrocentrus from Şanlıurfa. Chromosome preparations were made using cells from the male testes and the female ovariuteri of the species studied. Chromosome preparations were made using the classical spreading method. Results:The diploid chromosome number for Hottentotta saulcyi was 2n=14, and 2n=28 for Buthacus macrocentrus. Conclusion:The karyotypes of Hottentotta saulcyi and Buthacus macrocentrus have been presented for the first time. Both analyzed species have holocentric chromosomes that gradually decrease in size. Quadrivalent and hexavalent were observed during the first meiotic division in males of Buthacus macrocentrus.

“…In Palestine, we reported the karyotypes of Hottentotta judaicus 2n=16, Leiurus quinquestriatus 2n=22, and Scorpio maurus fuscus 2n=52 (Qumsiyeh et al 2013). The data above for Nebo adds an important element as it represents the first karyotype on the diplocentrid group within the Scorpionidae sensu lato.…”

“…We recently reported the karyotypes of three species from Palestine: Leiurus quinquestriatus, Hottentotta judaicus, and Scorpio maurus fuscus (Qumsiyeh et al 2013). The only other study of chromosomes in the Middle East was done in Egypt of some members of the genus Androctonus, which had a fairly uniform 2n=24 (Moustafa et al 2005).…”

Karyotype for <i>Nebo hierichonticus</i> (Simon 1872) from the Palestinian Territories (Scorpiones: Scorpionidae)

SummaryIn this paper we report the first karyotypic data on Nebo hierichonticus (Simon 1872) from the occupied Palestinian territories. The karyotype consists of 50 chromosomes which appear acrocentric except for pair 3, likely representing the XY. With additional data on scorpionidae coming through, we suggest that a model of chromosomal evolution might involve changes in chromosome numbers that relate to chromosomal stability in the nucleus and recombination affecting adaptability as previously suggested and supported by studies of salmonid fish chromosomes.
