Figs. 11–26  
Studied material: Cádiz: Algeciras, Mirador del Estrecho, 12 January 2007, A. Tinaut leg., male holotype deposited in MNCN, type number 2236, and 1 subadult male paratype (deposited in UCO, ref. Z2170).  
 Description. Body length of the holotype 8.5 mm, subadult, 6.2 mm. Antennae broken, maximum preserved length 6.5 mm. Terminal filaments broken, a cercus with only 1.5 mm preserved. General body shape campodeiform, with yellowish pigment uniformly distributed, slightly more intense in the posterior part. Head with scattered short hairs and few macrosetae.   
Antennae asymmetric in the holotype: left pedicellus with well-developed apophysis (Figs. 11, 12); right pedicellus with minute apophysis (Figs. 13, 14), very difficult to distinguish due to its width less than one-eighth the diameter of the pedicellus, its top not surpassing distal limit of this antennal segment; its setation consisting only of an apical glandular seta and four thin setae inserted in the trunk of the apophysis.  
Left apophysis wider than diameter of pedicellus, apical region reaching at least third division of flagellum; shape subovoid to subcylindrical with two lamellae or processes, one of which surrounds the apical glandular seta and the other with an acute sclerotized point (hook-shaped) under the aforementioned seta. These projections oriented to the inner side of the antenna and on this side below the lamellae, trunk of the apophysis with a strong bifid macroseta and some thinner and shorter setae. In the subadult specimen, asymmetric condition of the antennae less evident: both antennae with similar cylindrical apophysis (more simple than in adult) with apical glandular seta (Figs. 15–19).  
Mouthparts typical for the genus, the maxillae and the labial palp as illustrated in Figs. 20 and 21. Distal article of maxillary palp 6.5 times longer than wide and 1.7 times longer than penultimate article.  
 Thoracic nota as typical in Coletinia spp. Tibiae with two dorsal, one lateral and four ventral spiniform macrosetae; these setae shorter than the diameter of the tibiae (Fig. 22). Tibial spur denticulated in its hind margin (Fig. 23). L/W ratio of tibiae: protibiae = 2.95; mesotibiae = 3.2; metatibiae = 3.7.   
 Urotergites as typical for the genus. Tenth urotergite with posterior border slightly concave; posterolateral processes with 5+5 sensory pegs (Fig. 24). Pegs subcylindrical in shape, with slight apical emargination (similar to those in C. tinauti). Disc of urotergite X covered with robust setae.   
Urosternites I-VI as typical in the genus; posterior urosternites and genitalia not well preserved, but bearing 1+1 submedian, 1+1 sublateral and 1+1 distal bifid macrosetae. Urosternites VII, VIII and parameres not well preserved in holotype. In subadult, urosternite VIII with convex posterior border, protruding between the stylets (Fig. 25); parameres subcylindrical, 3.4 times longer than wide and slightly wider in the distal half than in the basal half; nearly as long as the ninth urosternite stylets.  
Cerci with 4 sensory pegs with blunt apex (Fig. 26), paracercus lost (broken in basal region).  
 Etymology. The species is named after Hercules, the god who, according to Roman and Greek mythology, separated the two sides of the Gibraltar Straits, on the northern side of which this new species was found.   
 Remarks. Coletinia herculea n. sp. is a member of the “ asymetrica ” group.   
 The shape of the left apophysis is unique in C. herculea n. sp. because it bears two lamellae with different shapes and positions, one apical and above the glandular seta and the other situated under this seta and with a sclerotized point. Coletinia vergitana n. sp. also has a nearly subcylindrical apophysis, but the shape of the expansions and sclerotizations, as well as the setation of the basal trunk of the apophysis, are very distinctive. Uniquely, the bifid apex has an expansion next to the glandular cone and field of setae that extends over the external margin of the apophysis.   
 Coletinia asymetrica from Córdoba, Spain, is probably the most closely related species because it has a subcylindrical apophysis, but it only has one sclerotized crest under the apical seta (Fig. 128). The pedicellus shape in the remaining species of this group (C. subterranea (Silvestri, 1902), C. brasiliensis Mendes & Ferreira, 2002) is very different from the two new species, and their geographic distribution is very far from the locations in southern Andalusia where C. herculea n. sp. and C. vergitana n. sp. have been collected.
