(1) Background: Scorpions (Arthropoda: Arachnida) represent a diverse group of invertebrates, accounting for a significant proportion of earth’s predators and ecosystems’ modulators. Surviving mostly in hardly reachable nests, and representing key hazards to human health, they attracted major interest for characterizing their eco-, morpho-, and genotypes. (2) Methods: Four scorpion species were collected from the New Valley governorate in Upper Egypt, where a high level of scorpionism and related neurological symptoms are found, that were Leiurus quinquestriatus, Androctonus amoreuxi, Orthochirus innesi, Buthacus leptochelys. They were DNA barcoded, genetically and phylogenetically analyzed through PCR amplification and sequencing of the mitochondrial cytochrome oxidase subunit 1 (COI) gene hypervariable 5′ region. (3) Results: New, morphologically authenticated scorpion barcodes could be added to the barcoding databases. However, several discrepancies and barcode database inadequacies could be revealed. Moreover, taxon-specific patterns for nitrogenous bases’ distribution could be identified, resulting in a significantly high percentage of COI barcode guanine in scorpionids, in comparison to araneids and opilions. (4) Conclusions: For a group of animals where both cryptic speciation and a high risk of human envenomation are evident, the findings of the current study strongly recommend continuous and comprehensive research efforts dealing with morphogenetic authentication for different species of scorpions.
Scorpionsare terrestrial arthropods inhabiting deserts. Exomorghological studies play an important role in the identification of different scorpions' species. The current study deals with the ecomorphology of four species of scorpions belong to the family buthidae (Leiurus quinquestriatus, Androctonus amoreuxi, Orthochirus innesi and Buthacus leptochelys) inhabiting New Valley governorate, Egypt. Random samples were implemented during the period from April to July, 2017 and July to September, 2019. Scorpions were obtained from the area under rocks, gap of soil, leaf litter, under bark, and within vegetation. Morphological characteristics of these species were done using a scanning electron microscope (SEM). In conclusion, the differences among four species of studied scorpions were noticed in the dorsal carapace, respiratory pores of the third segment of mesosoma, pectinal teeth count between females and males, last segment of metasoma and telson. In all scorpions' species studied, one venom pore was detected except in Androctonus amoreuxi two venom pores in telson were observed.
The main objective of the present study is to make a survey on scorpion species inhabiting New Valley governorate, Egypt as well as to make some morphometric measurements on the recorded species and to design a key for the recorded species. To achieve the aims of the study, random samples were collected during the period from April to July, 2017 and from July to September, 2019. The study revealed the presence of four scorpion species belonging to family Buthidae namely: Leiurus quinquestriatus, Androctonus amoreuxi, Orthochirus innesi and Buthacus leptochelys. The study provides a key for the identification of the species and some morphometric measurements. The morphometric measurements included: Carapace length, Mesosoma length, Metasoma length, Telson length, Aculeus length, Vesicle length, Pedipalp femur length, Pedipalp patella length, Pedipalp chela length and total body length. The study revealed significant differences between the recorded four species. It also revealed significant differences between males and females of each species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
