Cybaeodes dosaguas Ribera & De Mas, 2015

Cybaeodes dosaguas – Barrientos & Hernández-Corral 2022: 91 (♂ description).

This species was described from a cave in the south of the province of Valencia: Cova de les Meravelles, municipality of Dos Aguas (type locality). It has also been cited in the Serra d’Aitana, Alacant Province, in the alluvial MSS collected with a 100 cm long SSD ( Jiménez-Valverde et al. 2015) and in the edaphic environment with pitfall traps ( Barrientos & Hernández-Corral 2022) as well as in the Serra d’Espadà, Castelló Province, also with pitfall traps ( Hernández-Corral & Barrientos 2021). In the sampled area, of the 15 locations where specimens of Cybaeodes were captured, C. dosaguas was present in 12 of them. In 11 of these localities, it was the only species found, whereas in Serrella two species were collected together ( C. dosaguas and C. magnus ), thus being the only locality where more than one species appeared. A total of 278 adult specimens were caught in the alluvial and colluvial MSS (89 ♂♂, 189 ♀♀). Of the 278 specimens collected, 270 came from the colluvial MSS (8 sampled localities) and only 8 from the alluvial MSS (4 localities). It is also worth pointing out that all the males (89 ex.) appeared only in colluvial MSS in October, while females appeared throughout the year (sampled dates: January, April, June, July, September and October) in colluvial (181 ex.) and alluvial (8 ex.) MSS. These data suggest that this species preferentially inhabits the colluvial MSS, at least in the studied area. The scarce presence in the alluvial MSS may be explained because this type of underground environment is more dynamic and unstable due to the hydrological reactivation of the riverbed ( Ortuño et al. 2013; Ortuño & Jiménez-Valverde 2024). Despite this, it functions as an underground corridor, which explains the presence of many different species, including this spider. Cybaeodes dosaguas is the most abundant species and has a large distribution area (provinces of Castelló, València and Alacant) and has been reported from the edaphic environment, MSS and caves.
