Abstract

Hogna caduca Karsch, 1880 n. comb. (Fig. 7) Lycosa caduca Karsch, 1880: 82. Trochosa caduca – Roewer 1955: 301. Vesubia caduca – Roewer 1960: 746. TYPE MATERIAL. — Holotype. Hawaii • ♀; Olinda on the island of Maui; ZMB. REMARK Examining the type specimen of V. caduca (Fig. 7) revealed that it lacks the diagnostic characters of Vesubia. The epigynum with a straight, inverted T-shaped septum, along with the anterior pockets, unquestionably place this species within the Lycosinae, although none of the existing genera can be assigned to it with confidence. Accordingly, we propose to transfer V. caduca to to the genus Hogna, as Hogna caduca n. comb. Hogna is a paraphyletic genus that has not been reviewed, but in which many species with genital characters similar to this species are placed (Crespo et al. 2022). The World Spider Catalog (2024) indicates that this species is distributed in Polynesia, as indicated in the title of the Karsch’s (1880) publication, although material was collected in Olinda, on the Maui Island in Hawaii.
