  Hidden in the wrack: spider (Arachnida, Araneae) diversity and new records for Italy from Posidonia banquettes ABSTRACT Posidonia oceanica (L.) Delile beach wrack deposits (banquettes) are a characteristic coastal habitat of the Mediterranean Sea, yet their invertebrate communities remain poorly studied. Here we report the results of a survey from January to November 2024 of the spider fauna (Order Araneae) associated with Posidonia banquettes at Sant’Agostino beach (Civitavecchia, Latium, central Italy), using four complementary sampling methods (surface and underground pitfall traps, Berlese-Tullgren funnel extraction, and visual census). A total of 161 specimens were collected, with 17 species assigned to 11 families among adult individuals. The dominant families were Argyronetidae (39.4%), represented exclusively by Chaerea maritimus Simon, 1885, and Gnaphosidae (33.8%). Three species are recorded for the first time in Italy: Dysdera gamarrae Ferrández 1984, Gnaphosa jucu...

Formalization of nomenclatural acts proposed in Tang (2026) (Scorpiones: Buthidae, Chaerilidae, Scorpiopidae)

Abstract

Several nomenclatural, taxonomic, and faunistic decisions put forth in Tang (2026) are formalized herein: (1) four nomina dubia, Chaerilus tessellatus Qi et al., 2005, Scorpiops langxian Qi et al., 2005, S. pococki Qi et al., 2005, and Isometrus (Reddyanus) wenjieae Huang et al., 2025; (2) two junior subjective synonyms, Scorpiops langxian = S. pococki = S. tibetanus Hirst, 1911 syn. n.; (3) one new “aspidonym”, Scorpiops obluda Tang, 2026 sp. indet. nomen nudum; and (4) removal of Scorpiops hardwickii (Gervais, 1843) and S. petersii Pocock, 1893 from the Chinese scorpiofauna. Reddyanus tibetanus (Lourenço & Zhu, 2008) is maintained as a junior subjective synonym of R. assamensis (Oates, 1888). Alloscorpiops Vachon, 1980, Dasyscorpiops Vachon, 1974, Euscorpiops Vachon, 1980, Neoscorpiops Vachon, 1980, Plethoscorpiops Lourenço, 2017, Vietscorpiops Lourenço & Pham, 2015, and Alloscorpiops ( Laoscorpiops) Lourenço, 2013 are maintained as junior subjective synonyms of Scorpiops Peters, 1861.
