  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...

On Episinus maculipes Cavanna, 1876 in Belgium: a significant range expansion fifteen years after its initial discovery

Abstract 

Episinus maculipes, previously considered very rare in Belgium following its first observation in 2010, is here reassessed. New data reveal a sharp increase in observations, particularly since 2020, reflecting a rapid range expansion, with the species now recorded in all Belgian provinces. E. maculipes is expected to become widespread across Belgium.
