  An integrative description of Euscorpius diagorasi sp. n. from Rhodes, Greece (Scorpiones: Euscorpiidae) Abstract The genus  Euscorpius  Thorell, 1876 comprises a diverse and taxonomically challenging group of scorpions in the Mediterranean, with Greece representing one of its principal centers of diversity. In this study, we provide an integrative description of  Euscorpius diagorasi   sp. n. , a new species from Rhodes Island, Greece. The new species is described on the basis of adult male and female morphology and mitochondrial COI sequence data. It is a small oligotrichous species characterized by a total length of approximately 21–25 mm, pale yellow to light brown coloration with darker reddish-brown pedipalps, pectinal tooth count of 8 in the male and 7 in the females, Pv = 7–8, Pe-et = 5–6, and a distinct mitochondrial lineage. Phylogenetic analyses based on COI recovered the Rhodian specimens as a strongly supported monophyletic lineage, sister to...

FIRST RECORD OF RED-BACK SPIDER FAMILY THERIDIIDAE AND SPECIES LATRODECTUS HASSELTI (THORELL, 1870) (ARANEAE: ARACHNIDA) FROM DISTRICT GWADAR BALOCHISTAN, PAKISTAN

Abstract

Latrodectus hasselti (red back spiders) species belong to family theridiidae this was first reported by Thorell, 1870 from tropical and sub-tropical regions. The red back spider (Latrodectus hasselti), is a very poisonous species of spider. This species is well designated by their distinctive morphological structures and their male and female distinguish morphology. Morphometric features support vital discernments to its physical features, for identifications of the particular species, their behavioral and environmental analysis. Females of this species are significantly bigger than their males, usual body measurements of 25-17 mm, paralleled to 12-10 mm of males. Female of this species are described by the spherical abdomen, having protruding red stripes on dorsal part, whereas males frequently show bright color stripes. Leg sizes expose a distinctive leg formula which is IV > I > II > III, imitating for their prey capturing and web production. The Pedi palps of the males are extremely focused for their mating purpose and are divergent structurally in their structure from the females. Their morphometric qualities sustenance spider’s for reproductive process and their predatory approaches. Advance studies participating morphometric approaches which can boost up our understanding about the red back spider's compliance and population dynamics through various habitations. This species also first time recorded from district Gwadar Balochistan, Pakistan. This research work is based on ecology and morphometric of Latrodectus hasselti species (Thorell 1870) from Gwadar Balochistan Pakistan.
