Abstract
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 Buthacusleptochelys. 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.

Summary
Scorpions are the old arachnids on the earth. Scorpions are the most successful terrestrial arthropods inhabiting deserts worldwide (Polis and Yamashita, 1991). Desert scorpion species show ecomorphological specialization, specific habitats and morphological adaptations to the substrates such as sand (Prendini, 2001). Santibáñez- López et al (2015) said that about 2300 species of scorpions are distributed worldwide. Scorpions are widely distributed in Africa, Europe, and Asia, especially in Arabian countries like Lebanon Jordan, Iraq, Syria and etc (Vachon, 1966). New Valley Governorate or El Wadi El Gedid Governorate is one of the governorates of Egypt. It is in the southwestern part of the country, in Egypt's Western Desert (part of the Sahara Desert), between the Nile, northern Sudan, and southeastern Libya.
