Especies ibéricas del género Troglohyphantes Joseph, 1882 (Araneae, Linyphiidae)

Abstract

The available samples of the genus Troglohyphantes Joseph, 1882 in the Iberian Peninsula are reviewed; all of them from the Cantabrian Mountains and the Pyrenees (Spanish side). A new graphic characterization of the species found is made, and their possible affinities are discussed. The following synonyms are proposed: Troglohyphantes nyctalops Simon, 1911 n. syn. = Troglohyphantes cantabricus Simon, 1911; Troglohyphantes affirmatus (Simon, 1913) n. syn. = Troglohyphantes marqueti (Simon, 1884). Likewise, the mention of Troglohyphantes affinis (Kulczyński, 1914) is considered a “lapsus calami”. A new endemic species of the Cantabrian Mountains, Troglohyphantes machadoi sp. nov. and Troglohyphantes vasconicus sp. nov., are described. Thus, the species located in the Iberian Peninsula are: Troglohyphantes alluaudi Fage, 1919, T. bolivarorum Machado, 1939, T. cantabricus Simon, 1911, T. cerberus (Simon, 1884), T. furcifer (Simon, 1884), T. machadoi sp. nov., T. marqueti (Simon, 1884), T. orpheus (Simon, 1884), and T. vasconicus sp. nov. However, the internal variability of the “cerberus” group - subgroup “cantabricus” of Fage, which could contain new species that are morphologically poorly distinguishable, is confirmed.

Se revisan las muestras disponibles del género Troglohyphantes Joseph, 1882 procedentes de la Cordillera Cantábrica y de los Pirineos (vertiente española). Se hace una caracterización gráfica de las especies encontradas y se comentan sus posibles afinidades. Se proponen las siguientes sinonimias: Troglohyphantes nyctalops Simon, 1911 n. syn. = Troglohyphantes cantabricus Simon, 1911; Troglohyphantes affirmatus (Simon, 1913) n. syn. = Troglohyphantes marqueti (Simon, 1884). Así mismo, se considera un lapsus calami la mención de Troglohyphantes affinis (Kulczyński, 1914). Se describen dos nuevas especies endémicas de la Cordillera Cantábrica, Troglohyphantes machadoi sp. nov. y Troglohyphantes vasconicus sp. nov. Así, las especies localizadas en la Península Ibérica son: Troglohyphantes alluaudi Fage, 1919, T. bolivarorum Machado, 1939, T. cantabricus Simon, 1911, T. cerberus (Simon, 1884), T. furcifer (Simon, 1884), T. machadoi sp. nov., T. marqueti (Simon, 1884), T. orpheus (Simon, 1884) y T. vasconicus sp. nov. No obstante, se constata la variabilidad interna del grupo “cerberus” - subgrupo “cantabricus” de Fage, que podría encerrar nuevas especies morfológicamente poco diferenciables.
