Spiders from the Arganeraie Biosphere Reserve of Souss-Massa region (Morocco), and descriptions of two new species (Arachnida: Araneae: Gnaphosidae, Salticidae)

Résumé fourni par la source

This study presents a preliminary faunistic survey of spiders from the Arganeraie Biosphere Reserve in the Souss-Massa region of Morocco covering 39 species across 17 families collected between January 2022 and June 2025. Two species are new to science: Cesonia africana Lecigne & Ouakri sp. nov. and Menemerus currens Lecigne sp. nov. Five other species are new records for Morocco, i.e., Nemesia uncinata Bacelar, 1933, Phlegra yaelae Prószyński,1998, Mogrus sahariensis Berland & Millot, 1941, Cebrennus laurae Jäger, 2014 and Polenecia producta (Simon, 1873). Several other species, already known from Morocco, are noteworthy taxa, e.g., Aelurillus hirtipes Denis, 1960, Cebrennus rungsi Jäger, 2000, Eresus elhennawyi Řezáč, Vaněk & Střeštík, 2023, Oecobius machadoi Wunderlich, 1995, Olios pictus (Simon, 1885) and Steatoda ingeae Van Keer, 2024. The following new synonym is proposed: Zelotes oryx (Simon, 1880) = Zelotes tragicus (O. Pickard-Cambridge, 1872) syn. nov. Our findings expand our knowledge of Moroccan spiders and highlight the biodiversity of historically poorly studied habitats, thus warranting further, targeted research.
