Diagnosis

Males differ from those of other species of the genus, in particularly from those of C. magnus ( Fig. 6 ), C. dosaguas , C. bernia sp. nov. ( Fig. 3 ), and C. indalo , which are the most morphologically similar and geographically closest species, by the shape and size of the cymbium, the tibial apophysis, the median apophysis, the embolar base, and the embolus itself. In C. gallinera sp. nov. the cymbium is markedly wider in its basal part than in the rest of the species due to a pair of bulging expansions located on both sides of its base ( Fig. 5 ). The median apophysis is long, thick and hook-shaped similar to those of C. magnus and C. bernia sp. nov. although in C. gallinera the apical hook is more developed. Cybaeodes dosaguas and C. indalo have a longer and thinner median apophysis and their apical hooks are less pronounced. The new species shows a wide, rectangular embolar base, and the laminar embolus loop is completely in the distal area of the alveolus, which ends behind the median apophysis. In C. bernia , C. magnus , and C. indalo the embolar base is more elongated, and the embolus itself is markedly shorter and thinner, especially at the end.

Etymology

The species epithet is a noun in apposition derived from the type locality: La Vall de la Gallinera (the Gallinera Valley). The noun ‘gallinera’, which the Arabs called ‘galinar’, is a pre-Roman word formed by ‘kal’ + ‘inar’, where ‘kal’ means ‘rock’ and ‘inar’ means ‘cut’ or ‘hole’, resulting in the ‘Vall de la Foradada’ in the Catalan language.

Type material

Holotype SPAIN – Alacant • ♂; Barranc de la Vall de la Gallinera , Benirrama; 38°48.966′ N, 0°14.145′ W; 160 m a.s.l.; Sep. 2012; V. M. Ortuño et al. leg.; SSD 50 cm long (SSD-Alu1, alluvial MSS); CRBA-UB 5337-200 .

Description

Male

COLORATION. Prosoma pale yellowish with the cephalic part slightly darkened, anterior margins pale brown. Fovea brown. Chelicerae pale yellowish-brown, slightly darker than the prosoma. Sternum and appendices pale yellowish, with apical segments slightly darker. Opisthosoma pale yellowish with slight pubescence on dorsal part.

PROSOMA. Longer (1.97) than wide (1.60) in dorsal view, fovea clearly visibly, radial grooves scarcely marked. Cephalic region slightly differentiated from the rest of the prosoma. Eyes clearly reduced and depigmented ( Fig. 5E ). Eye size (diameter): AME 0.05, ALE 0.08, PME 0.05, PLE 0.07.

OPISTHOSOMA. Cylindrical with light pilosity on dorsal side and some short, thick and curved hairs located on its anterior end, above the pedicel. Elongated and sclerotized anterior lateral spinnerets (the typical extended spigots are missing, likely due to poor preservation). Posterior spinnerets also cylindrical, but shorter and thinner than the anterior lateral ones, the medium ones are smaller.

APPENDAGES. Robust and prominent chelicerae with pilosity along the promarginal rim. Long and robust fangs. Promargin with 3 basal teeth, middle tooth largest. Retromargin with 2 small apical teeth. Labium slightly longer than wide. Palpal endites subrectangular and slightly convergent. Endites with an apical hair tuft located at the internal side of the apical margin along with a long serrula of tiny teeth (difficult to see). Long legs with deeply notched trochanters. Tarsal claws with 5 teeth and 5 pairs of tenent hairs on the tarsal tips. Leg formula 1423.

MALE PALP ( Fig. 5A–D ). Tibia with robust 4 spines: one dorsal and 3 prolateral. Retrolateral tibial apophysis long and triangular, 2 times as long (0.20) as wide at its base (0.10) and distally pointed ( Fig. 5C–D ). Tegulum wide, located in the basal part of the bulb, its anterior edge is chitinized and shows a short, wide apical extension located between the base of the embolus and the median apophysis. Robust and elongated median apophysis, cylindrical in appearance and rounded at its apical end, with a conspicuous tooth located near the center and directed posteriorly. Wide, rectangular embolar base. Long, laminar embolus forming a complete loop, curved inwards in the distal area of the alveolus and ending behind the apex of the median apophysis.

MEASUREMENTS. PL 1.97; PW 1.55; OL 2.33; OW 1.16; total body length 4.30. Leg and palp measurements in Table 3 .

Female

Unknown.

Habitat and distribution

MSS-dwelling species showing adaptations to underground environment: pale pigmentation, reduced, depigmented eyes. Only known from the type locality, an alluvial MSS sampled with a 50 cm long SSD.
