Figs. 27–40

Studied material. Almería : Berja , Sierra de Gádor, Cueva del Águila, 22 March 2004, P. Barranco and J. G. Mayoral col., male holotype, 1 female paratype and 1 juvenile paratype, deposited in MNCN, type number 2237 .

Description. Holotype body length: approximately 13 mm. Antennae broken, maximum length preserved 6.5 mm. Subadult length 10.5 mm. Body pale yellowish, with the pigment slightly more intense in the posterior segments.

Head with sparse short setae and regularly arranged macrosetae ( Fig. 27 ). Lateral region of head where maxillae are inserted (condyles) very conspicuous due to intense sclerotization and dark pigmentation.

Antennae with left pedicellus showing a very developed apophysis, 1.2 times wider than pedicellus and nearly 2 times longer than wide, and reaching seventh joint of flagellum ( Figs. 28–30 ). Basal portion of left apophysis subcylindrical and bearing on the outer side a longitudinal field of thin setae whose length increases distally. Apical portion of apophysis bifid, with two processes, the usual cone with a glandular seta and a lateroexternal expansion with a rounded shape and two bifid macrosetae on the external side; these macrosetae similar to the three remaining macrosetae inserted in the pedicellus, near the base of the apophysis. On the external side of the lateroexternal expansion, a thin seta next to the glandular cone and surpassing the top of the cone. The tegument of this expansion pilose, covered with small hairs; external side of the trunk of the pedicellus also pilose and covered with small hairs in the region of the longitudinal field of thin setae. Glandular cone with truncated apex and relatively long glandular seta; cone tegument smooth, but on the external side next to the lateroexternal expansion, tegument with a conspicuous hook-shaped sclerotized prolongation with a basal zone bearing some teeth in the margin resembling the molar area of a mandible ( Fig. 30 ). Right pedicellus with small, rounded apophysis, in its apical internal angle bearing six thin setae; length/width ratio 0.5, width of apophysis/width of pedicellus approximately 0.3. Pedicellus with four long bifid macrosetae ( Figs. 31, 32 ).

Apophyses of subadult specimen similar, about 2 times longer than wide, but less developed than in the adult and narrower than the pedicellus (width of the apophysis/width of the pedicellus ratio approximately 0.4) and their tips reaching only to fourth subdivision of the flagellum; special structures lacking except for the apical glandular seta. A few thin setae inserted in the apophysis. Four long, bifid macrosetae inserted in the pedicellus, absent from apophysis ( Fig. 33 ).

Basal part of maxilla with two pigmented areas (condyles). Distal article of maxillary palp in male about 7 times longer than wide (5.25× in the female and 5× in subadult) and 1.3–1.5 times longer than the penultimate article. Labial palp without remarkable features.

Thoracic nota typical of the genus. Length/width ratio of tibiae as follows: protibiae 3.5–4, mesotibiae 4–4.5, metatibiae 5.2–5.4. Pro—and mesotibiae with 2 dorsal (one medial, one distal) and 4 ventral (2 subdistal, 2 proximal) spines, metatibiae with 5 spines (1 inserted basally, 2 medially, 2 subdistally). All tibiae with few additional small basal and medial spines ( Fig. 34 ). Lateral spine usually present.

Urotergites typical for Coletinia . Tenth urotergite of male with concave posterior border and 6+7 sensory pegs inserted in lateral margin of the posterolateral lobes and 1+1 sensory pegs inserted in disc of urotergite, at the level of the apex of the posterolateral lobes. All pegs short, subcylindrical, truncated at the apex. Lateral area of disc covered with very robust, acute setae ( Fig. 35 ).

Tenth urotergite of female with 1+1 strong bifid macrosetae inserted in posterolateral angles, and around them, 1+1 fields of strong acute setae ( Fig. 36 ). Posterior border not clearly observed, but straight or slightly concave.

Urosternite I divided, urosternites II–VII with 1+1 submedian, 1+1 sublateral and 1+1 discal bifid macrosetae. Eighth urosternite of male with its hind border slightly convex, not much protruding, with subtrapezoidal shape, resembling a blunt obtusangle triangle ( Fig. 37 ). This margin is bent in the subadult specimen, but it seems to have a concave median region.

Subgenital plate of the female semielliptical, wider than long (length/width ratio about 0.85), its posterior border rounded, but slightly truncated in the median region ( Fig. 38 ).

Parameres 4.3 times longer than wide, very similar in the subadult specimen.

Ovipositor long, with 30 divisions, extending beyond the apex of the ninth stylets more than three times their length ( Fig. 39 ).

Cerci and paracercus broken, the cerci of the male with 2–3 subacute basal pegs, paracercus with 5 acute pigmented spines in its basal divisions ( Fig. 40 ).

Etymology. The specific name of this new taxon refers to Vergis, the Roman name of Berja, a town in the province of Almería (SE Spain). The cave where C. vergitana n. sp. was found is within the municipal boundaries of this town.

Remarks. Coletinia vergitana n. sp. is a member of the “ asymetrica ” group. Distinguishing characters for this new species are given in Remarks under C. herculea n. sp., above.
