  Notes on Indian wolf spiders: IV. Transfer of species previously included in the genera Crocodilosa Caporiacco, 1947 and Geolycosa Montgomery, 1904 (Araneae: Lycosidae) The enigmatic Crocodilosa Caporiacco, 1947 sensu lato currently consists of five nominal species distributed in Africa and Asia (World Spider Catalog 2026). It was established for C. kittenbergeri Caporiacco, 1947, with a superficial generic diagnosis relying only on somatic features such as length of eye rows, leg spination and relative leg lengths (Caporiacco 1947). Roewer (1955), following Caporiacco’s (1947) generic diagnosis, drastically increased the number of Crocodilosa species by transferring several species from other lycosid genera, but most of these subsequently added species were later reassigned to their appropriate genera (World Spider Catalog 2026), highlighting the need for a re-examination of the type species and remaining congeners to clarify the validity of Crocodilosa. At present, the genus ha...

A baffling case of morphological, molecular and ecological discordance in Isometrus Ehrenberg, 1828 (Scorpiones: Buthidae) with the description of five new species from southern India

Abstract

The Western and Eastern Ghats of the Peninsular India are known for their high biological diversity, which is shaped due to various geological barriers and environmental parameters. Scorpion diversity in Peninsular India remains poorly known thereby warranting a need to undertake rigorous arachnological surveys. In our continued effort to discover scorpion lineages hitherto unknown to science, we describe five new species of the genus Isometrus Ehrenberg, 1828 which were obtained from southern India, and discuss morphological, molecular and ecological discordance within this genus. The validity of Reddyanus atherii Amir and Kamaluddin, 2008, Isometrus liaqatii Amir and Kamaluddin, 2008 and Isometrus formosus Pocock, 1894 is also commented upon, with implications to propose taxonomic changes within the genus.
