Figs. 76–90

Studied material. Valencia, Serra, Sima Pla dels Llomes. 3 May 2006, male holotype and 2 female paratypes, collected with bait traps. Deposited in MVHN , Cod.: 030606 PL1 .

Description. Male length 14.5 mm, females up to 17 mm. Colour uniformly pale yellowish. Macrosetae with a high degree of spiralization, with 4–5 or more turns ( Fig. 76 ). Head with scarce long macrosetae and a few sparse thin setae.

Antennae longer than the body, reaching 17 mm in the holotype. Apophyses of the pedicellus of the male symmetrical, with similar structure to other Iberian species, (e.g, C. capolongoi ), having a subapical lamellar projection connected by an indented and somewhat sclerotized region to the glandular cone ( Fig. 77 ), delimiting a subcircular smooth cavity. Basal trunk of pedicellus with few thin acute setae and five bifid macrosetae: one strong macroseta in basal region of the pedicellus opposite the base of the apophysis, two long macrosetae inserted in the median region of the basal trunk and two subequal, shorter macrosetae near the subapical process. Apical part of apophysis reaching the suture between the fourth and fifth joints of the flagellum.

Distal article of maxillary palp about 4.5–5 times longer than wide and slightly longer than penultimate article (ratio of distal to penultimate less than 1.1) ( Fig. 78 ). Labial palp without remarkable features.

Tibiae very long, L/W ratio given in Table 2. Metatibiae 6.8–7 times longer than wide ( Figs. 79–81 ). Tibial spines shorter than diameter of tibia; usual number of tibial spines as 2 dorsal (1 medial and 1 distal), 1 lateral and 4–6 ventral; dorsal side of protibia sometimes bearing 3 or 4 spines. Tibial spur clearly denticulated ( Fig. 82 ).

Tenth urotergites of the male and female specimens folded on slides, posterior borders not seen clearly. Male posterolateral lobes bearing 8+8 sensory pegs ( Fig. 83 ), disc likely densely covered with setae ( Fig. 84 ). Posterior border of female probably slightly concave and the disc with few setae, which are more concentrated in the posterolateral regions ( Fig. 85 ).

Urosternites typical, with 1+1 submedian, 1+1 sublateral and 1+1 discal bifid macrosetae. Posterior border of urosternite VIII of male protruding and convex but nearly straight or truncated near the midline ( Fig. 86 ). Subgenital plate of female semielliptical, with posterior border strongly convex, arched ( Fig. 87 ), L/W ratio of this sclerite approximately 0.87.

Parameres about 5 times longer than wide and as long as the ninth stylets ( Fig. 88 ). Ovipositor long, with 18 divisions, surpassing paramere apex by 1.1 times their length, or 1.5 times if apical spine of stylet is not taken into account (see Fig. 89 ).

Terminal filaments broken. Cerci up to 16 mm long, in the male with 6 acute pegs with a blunt apex ( Fig. 90 ). Paracercus broken at its base in the holotype, with only 1 medioventral spiniform peg visible; paracercus up to 14 mm long in females.

Etymology. The specific name for C. longitibia n. sp. refers to the extreme relative length of the tibia, greater in this species than in any other European species.

Remarks. C. longitibia n. sp. differs from all Iberian Coletinia in the high L/W ratio of the tibiae. Only one other Coletinia species , C. longissima from Turkey ( Mendes, 1988), has longer tibiae (length/width ratio about 9), but the Turkish species differs in the shape of the male pedicellar apophysis, which is longer and bears a thin, curved, long expansion (nothing similar within Spanish Coletinia ), and in other features such as the higher number of sensory pegs on the tenth urotergite and the shorter ovipositor. Some large specimens belonging to C. capolongoi can reach a similar L/W ratio of the tibiae, as the illustrations in Wygodzinsky (1980) suggest, but these specimens are nearly 20 mm long, and specimens of C. longitibia n. sp. with an L/W ratio of the metatibiae of approximately 7 are smaller.

Coletinia longitibia n. sp. belongs to the group “ capolongoi ” and is particularly related to those species found in the northern Spanish Mediterranean ( C. capolongoi , C. redetecta n. sp.), having larger size and a convex hind border of the eighth urosternite in males and subgenital plate in females.
