Notes on Indian wolf spiders: IV. Transfer of species previously included in the genera Crocodilosa Caporiacco, 1947 and Geolycosa Montgomery, 1904 (Araneae: Lycosidae)

  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...

Four new species of the spider genus Oecobius Lucas, 1846 (Araneae: Oecobiidae) from northwestern Mexico

Abstract

Four new species of the genus Oecobius Lucas, 1846 (Araneae, Oecobiidae) from northwestern Mexico are described, all of them based on both sexes: O. culichi spec. nov. and O. yoreme spec. nov. from Sinaloa, O. yaqui spec. nov. from Sonora, and O. sudcaliforniana spec. nov. from Baja California Sur. In addition, we provide taxonomic remarks of two native species: O. hoffmannae Jiménez & Llinas, 2005 and O. isolatoides Shear, 1970.
