MARTINEZ, Mariano I. The sea cucumber Psolus patagonicus (Echinodermata: Holothuroidea) from the southwestern Atlantic: Redescription of the holotype and a new synonym. Rev. Mus. Argent. Cienc. Nat. [online]. 2016, vol.18, n.2, pp.237-241. ISSN 1853-0400.

Psolus patagonicus Ekman, 1925 is redescribed from material including the holotype, deposited in the Zoologisches Museum Hamburg (ZMH), and specimens of the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (MACN-In). Psolus marcusi Tommasi, 1971 is stated as a junior synonym. Since also the specimens used by Ludwig in 1897 to report the brooding behavior of Psolus antarcticus (ZMH: E4168) are identifiable as P. patagonicus, the latter is the only South American psolid holothuroid known to be a brooder.

Keywords : Dendrochirotida; Psolidae; Type material; Reproductive behavior.
