Two new species of the genus Philoponella from Brazil and Argentina (Araneae, Uloboridae)

Abstract

Two new species of the genus Philoponella Mello-Leitão, 1917 are described: P. ramirezi, from the Atlantic forest of the State of Minas Gerais, Brazil, and P. pomelita, from the subtropical forests of the Province of Misiones, Argentina. Relationships of these new species are discussed

Copulatory mechanics of ghost spiders reveals a new self‐bracing mechanism in entelegyne spiders

“…In contrast to this usual situation in spiders, Josa has a particularly short patella and tibia, which seems to be crucial for the engagement of the femoral apophysis in the tegular projection, that would be otherwise too far apart to interact. A similar organization can be seen in few groups with femoral modifications: males of Orthobula and Capobula (Trachelidae) (see Haddad et al, 2022 and 2021, respectively) bear a hook‐like femoral apophysis similar to that of Josa , and males of Philoponella , Conifaber and Zosis (Uloboridae) have a basal femoral protuberance that comes into contact with the copulatory bulb in artificially expanded pedipalps (see Grismado, 2004: figs. 38 and 39).…”

Three new species and new records of the orb-weaving spider genus Philoponella (Araneae, Uloboridae) from Brazil and Ecuador

“…However, Opell did not mention the specific localities of the material examined, thus limiting the possibilities of accessing each species distribution. Only four new species of Philoponella have been described for the Americas after Opell's (1979) revision: Philoponella subvittata Opell, 1981, P. herediae Opell, 1987, P. ramirezi Grismado, 2004 and P. pomelita Grismado, 2004(Opell 1981, 1987, Grismado 2004.…”
