“…Scorpions are venomous arthropods and considered as one of the oldest arthropods because of their general characteristics and morphology that have not been changed much from their ancestors. Remains of scorpions were detected in fossils aged nearly 400 million years old [1]. Scorpion measurement boundaries are from 1.3 to 7.2 cm, and they are easily identifiable owing to their morphological structures.…”

Scorpion sting is still a heath problem and a serious issue threatening public health in many countries of the world including Kurdistan-region of Iraq. The current study aimed to find out the spatial distribution of scorpion stings and their clinical features in the north region of Iraq. It could be mentioned that the present research work is the first comprehensive attempt to highlight the epidemiological aspects of scorpionism and clinical manifestations of individuals bitten by scorpions in Iraq. To meet the requirements of the survey and epidemiological pattern, all the cases (n = 4162) of scorpion stings that attended the primary health care centers and clinics from January 1, 2017 to December 31, 2018 in Erbil, Duhok and Sulaymaniyah provinces were considered. Moreover, the monthly frequency of scorpion stings at the provincial level were perceived and exploited for epidemiological mapping. However, scorpion envenomation is a neurotoxic syndrome, but other disorders such as cardiac failure, acute pulmonary edema, shock and death can occur. Fortunately, most of the scorpion stings in adults in Kurdistan-region of Iraq are deemed mild envenomation. Having said severe cases with highly systematic envenomation was reported in Erbil province during the study period. At the study time, 41% of the cases were found in Erbil followed by Duhok (34%) and Sulaymaniyah (25%), and the scorpionenvenomed individuals aged 15-49 years. Regarding seasonal variations, the peak of scorpion stings was elevated in June, July and August, whilst lowered in January and February. On the other hand, the highest scorpion stings were recorded in 2017 as compared to 2018. Based on the results, it has been concluded that scorpionism is a dangerous health dilemma in Kurdistan-region of Iraq with a high risk level of scorpion envenomation during summer season in the area.

“…According to our data, DNA molecules of charinids are terminated by the so-called insect telomeric sequence (TTAGG) n , which is ancestral for arthropods [17]. This motif has been identified in many arachnid orders [17,35,45,78,79,89,91], including a whip spider of the family Phrynichidae, Damon medius [17]. While the same telomeric motif is usually shared by taxa on higher taxonomic levels, exceptions do occur [92][93][94][95], including arachnids [17].…”

“…The major rDNA cluster (45S rDNA) is by far the most utilized molecular chromosomal marker across diverse eukaryotic organisms, and especially in non-model groups [72][73][74]. The major rDNA cluster visualized either by 18S or 28S rDNA probes has already been localized in some spiders [36,46,73,[75][76][77], scorpions [45,76,[78][79][80][81][82], pseudoscorpions [83], harvestmen [84][85][86][87], ticks [73,88,89], and an amblypygid [18]. Mapping of this cluster often revealed a single NOR site, which is probably an ancestral pattern in arachnids [36].…”

Whip spiders (Amblypygi) represent an ancient order of tetrapulmonate arachnids with a low diversity. Their cytogenetic data are confined to only a few reports. Here, we analyzed the family Charinidae, a lineage almost at the base of the amblypygids, providing an insight into the ancestral traits and basic trajectories of amblypygid karyotype evolution. We performed Giemsa staining, selected banding techniques, and detected 18S ribosomal DNA and telomeric repeats by fluorescence in situ hybridization in four Charinus and five Sarax species. Both genera exhibit a wide range of diploid chromosome numbers (2n = 42–76 and 22–74 for Charinus and Sarax, respectively). The 2n reduction was accompanied by an increase of proportion of biarmed elements. We further revealed a single NOR site (probably an ancestral condition for charinids), the presence of a (TTAGG)n telomeric motif localized mostly at the chromosome ends, and an absence of heteromorphic sex chromosomes. Our data collectively suggest a high pace of karyotype repatterning in amblypygids, with probably a high ancestral 2n and its subsequent gradual reduction by fusions, and the action of pericentric inversions, similarly to what has been proposed for neoamblypygids. The possible contribution of fissions to charinid karyotype repatterning, however, cannot be fully ruled out.

Pseudoscorpions represent an ancient, but homogeneous group of arachnids. The genus Lamprochernes comprises several morphologically similar species with wide and overlapping distributions. We implemented an integrative approach combining molecular barcoding (cox1), with cytogenetic and morphological analyses in order to assess species boundaries in European Lamprochernes populations. The results suggest ancient origins of Lamprochernes species accompanied by morphological stasis within the genus. Our integrative approach delimited three nominal Lamprochernes species and one cryptic lineage Lamprochernes abditus sp. nov. Despite its Oligocene origin, L. abditus sp. nov. can be distinguished from its closest relative only by molecular and cytogenetic differences, or alternatively, by a complex multivariate morphometric analysis involving other Lamprochernes species. The population structure and common haplotype sharing across geographically distant populations in most Lamprochernes species suggest that a phoretic manner of dispersal is efficient in this group.
