The very detailed description by Mauriès (2013) is of the highest quality. Concerning external morphology it is worth noticing that the specimen from Bernia differs from those from Confrides in having pigmented eyes while it agrees with the Confrides specimens in all other characters except for some minor differences (see discussion) which we regard insignificant. The SEM pictures presented here ( Figs. 2 , 3 ) complete Mauriès’ description and reveal some hitherto undescribed morphological details such as the shallow, inconspicuous evaginations of the cuticle at the place of the eyes ( Fig. 2 C–E) that are almost impossible to appreciate with optical microscopy, due to the absence of pigment. Also, there is a cobblestone paving-like microsculpture below the insertion of the antennae ( Fig. 2 C–E), similar to that found by Reboleira & Enghoff (2014) in Sireuma nobile Reboleira & Enghoff, 2014.

The new records allow us to elaborate an updated distribution map of the genus ( Fig. 1 A) and a key to species, illustrated with comparative images of the gonopods ( Fig. 4 ).

FIGURE 1. Distribution map of the genus Typhlopsychrosoma and pictures from the site where T. baeticaense appeared in the MSS. A) Map of the Iberian Peninsula; scale bar 200 km and B) Map of Alicante region; Scale bar 20 km. The white stars correspond to the new localities of T. baeticaense: 1) MSS, Sierra de Aitana, Confrides, Alicante province; 2) MSS, Bernia Mountains, Xaló, Alicante province. White diamonds correspond to previous records of T. baeticaense: 3) Cueva de los Murciélagos, Zuheros, Córdoba province; 4) Cueva de las Golondrinas, Carcabuey, Córdoba province; 5) Cueva del Nacimiento de San Blás, Siles, Jaén province; 6) Complejo del Arroyo de la Rambla, PB- 4, Peal de Becerro, Jaén province. White squares correspond to the localities of T. tarraconense: 7) Cova Cambra, Tortosa, Tarragona province; 8) Cova de Yerret, Alfara, Tortosa, Tarragona province; 9) Cova de Rabosa, Perelló, Tarragona province. Black circle with white margin corresponds to T. breuili: 10) Cueva Mayor, Atapuerca cave system, Ibeas de Juarros, Burgos. White circles correspond to the localities of T. fadriquei: 11) Cueva del Oro, Cornión, Asturias province; 12) Pozu Palomeru, Cornión, Asturias province; 13) Hoya la Madre Cave, ravine of Casaro River, 5 km from Lago Ercina, Picos del Cornión, Belbin, Asturias province; 14) Cueva de la Marniosa, Sobra Valley, Tresviso, Asturias province. C) Bare scree in Aitana Mountains where the MSS was sampled. D) Process of installation of the PVC cylinder. E) Aspect of the PVC cylinder once buried, and pitfall trap with the propylene glycol and the bait.

FIGURE 2. Habitus and body details of T. baeticaense from Aitana Mountains. A) Female in lateral view. Most dorsal setae were not preserved. Scale bar 0.5 mm. B) Body rings of male in lateral view. Scale bar 0.5 mm. C-E) Head and first rings of male in different views. Scale bars: C, E, 0.5 mm; D, 0.1 mm. F) Telson and last rings of male in lateroposterior view. Scale bar 0.5 mm.

FIGURE 3. Gonopods of P. baeticaense from Aitana Mountains. A) Posterior view. B) Left lateral view. C) Inferior (apical) view. D) Anterior view. The syntelopodite T is coloured in blue, part K of the colpocoxite, including its final tip and the bundle of bristles (‘ lanières’) in red, and part C of the colpocoxite in yellow. The labels indicate: C, c, K: parts of colpocoxite; f: bundle of bristles (‘ lanières’); T: basal part of syntelopodite; t: lateral process of syntelopodite. All scale bars 0.1 mm.
