Mahnert, Volker, 2011, Pseudoblothrus infernus sp. n. (Pseudoscorpiones, Syarinidae) from the Hölloch cave (Schwyz, Switzerland), with new records of Pseudoblothrus strinatii Vachon from Switzerland and France, Revue suisse de Zoologie 118 (1), pp. 11-15 : 12

Pseudoblothrus strinatii Vachon

NEW RECORDS: MHNG, Switzerland, Jura Mountains, Boudry ( canton of Neuchâtel ), source de Combe-Garot, gorges de l’Areuse, 533 m a.s.l., found in a water filtrating net; 8.IX.1985, leg. P. Moeschler: 1 protonymph . – MHNG, France, Département Doubs, Chenecey-Buillon, gouffre des Granges-Mathieu , piège; 18.VIII.1968, leg. H. Colin: 1 tritonymph .

REMARKS: The “source de Combe-Garot” is also where the harpactoid Gelyella monardi Moeschler & Rouch, 1988 (Crustacea) was collected, again by water filtration. Since the protonymph of P. strinatii is undescribed, specific identification is based on geographical considerations.

Three males from the cave “Grand creux de Montfaucon (cave BE 37 in Strinati, 1966) show the following proportions of pedipalpal patella and chela (with pedicel): patella 4.2-4.7 times longer than broad (0.89-1.00 mm/ 0.21 mm), chela with pedicel 5.6-5.9 times longer than broad (1.65-1.86 mm / 0.29-0.31 mm), finger l.4-l.5 times longer than hand with pedicel. These proportions are more slender than those indicated for the holotype from the Grotte de Pertuis ( Strinati, 1966: cave NE 26 by Vachon, 1957). All three males possess three patches of glandular setae in their ventral gland.
