  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...

Brown Recluse Spider Toxicity (Healthcare Continuing Education CME)

Continuing Education Activity

In the United States, Loxosceles reclusa, or brown recluse spiders are found mostly in the south, west, and Midwest areas. They are usually in dark areas such as under rocks, in the bark of dead trees, attics, basements, cupboards, drawers, boxes, bedsheets, or similar locations. Dermonecrotic arachnidism is the local tissue injury that results from brown recluse spider envenomation, while loxoscelism describes the systemic syndrome caused by envenomation. This activity reviews the pathophysiology and presentation of the brown recluse spider bite and highlights the role of the interprofessional team in its management.

Objectives:

  • Describe the pathophysiology of a brown recluse spider bite.
  • Review the presentation of a brown recluse spider bite.
  • Outline the treatment and management options available for a brown recluse spider bite.
  • Summarize interprofessional team strategies for improving care and outcomes in patients suffering a brown recluse spider bite.
