Pseudosinella cavernicoles d'Espagne. (Insecta: Collembola)

New species ofPseudosinella(Collembola: Entomobryidae) from karst caves of the Basque bio-speleologic district

“…The differences with P. goughi Gisin & Gama, 1972, are the labial chaetotaxy, m 1 (M 1 )m 2 Rel 1 l 2 in P. goughi, the claw structure, much more derivative in the species of Gisin & Gama, since it does not have the medial tooth and proximal teeth are more basal of P. luquei n. sp. In addition, tibiotarsal tenent hair is pointed in P. goughi.…”

“…Formula of labial base: M 1 M 2 REL 1 L 2 , but in Mairuelegorreta (Gorbea) and Iguaran (Entzia) in Araba, Arleze (Urbasa) in Navarra, "Cueva de Tío Marcelino" (Tudanca) and "Cueva de los Hornucos" (Hermandad de Campoo de Suso) in Cantabria, their populations have some specimens with variations in several setae M 2 , E and/or L 1 ; however L 2 is always ciliated and the formula M 1 m 2 Rel 1 l 2 of P. suboculata (Gisin & Gama, 1972) never appears. Seta M 1 equal or slightly shorter than M 2 ; seta R between 1/2 and 2/3 seta M 2 .…”

“…Antennae shorter (1.4 to 1.9 times the cephalic diagonal) than in P. suboculata (2 to 2.3 times). Gisin and Gama (1972), in the redescription of Bonet species, pointed out that their studied specimens were completely colourless, probably because of the conservation conditions. Specimens of P. suboculata studied in the present work were not completely colourless but 394 E. BERUETE, E. BAQUERO & R. JORDANA …”

Review of Eyeless Pseudosinella Schäffer (Collembola, Entomobryidae, and Lepidocyrtinae) from Brazilian Caves

“…nov. is similar to P. goughi Gisin and Gama, 1972, but the new species differs by unguis m.t. present and unguiculus pe lamellae with outer tooth, both features absent in P. goughi [50]. [50].…”
