  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...

Revisiting the tarantula genus Neischnocolus Petrunkevitch, 1925 (Araneae, Theraphosidae): new insights on male palpal bulb morphology and description of three new species

Abstract

We reassess the palpal bulb morphology and taxonomy of Neischnocolus Petrunkevitch, 1925 based on the examination of several types of previously described species and the description of three new species (N. moraspungo Cisneros-Heredia, Peñaherrera-R., Guerrero-Campoverde, León-E., Gabriel & Sherwood sp. nov., N. samonellaacademy Peñaherrera-R., León-E., Guerrero-Campoverde, Gabriel, Sherwood & Cisneros-Heredia sp. nov., and N. tiputini Guerrero-Campoverde, Peñaherrera-R., León-E., Gabriel, Sherwood & Cisneros-Heredia sp. nov.) from Ecuador. A new keel structure is named and herein considered as a valid diagnostic feature for the genus, previously identified as a prolateral inferior keel. The rest of the keel identification of Neischnocolus is also relabelled in concordance with Bertani’s (2000) keel homology hypothesis. Amended diagnoses of almost all the species are provided, leaving only Neischnocolus obscurus (Ausserer, 1875) since the type material has not been located.
