Figs. 65–75 View FIGURES 65–71 View FIGURES 72–75
Studied material. Alicante , Denia, Cova de la Punta de Benimaquia. UTM 31SBD451011. 31 October 2004, male holotype. A. Sendra et al., coll., deposited in MVHN , Cod.: 201206 RV85 .
Description. Body length 11.2 mm. Antennae broken, only 1 mm preserved. Terminal filaments broken, maximum length of cercus 6 mm. Body uniformly yellowish. Macrosetae clearly spiralized, particularly evident in the head and coxae, each containing 4–5 turns of the spiral ( Fig. 65 View FIGURES 65–71 ).
Head with relatively abundant short, thin setae and few bifid macrosetae ( Fig. 66 View FIGURES 65–71 ). Antennal apophysis reaching fourth joint of flagellum, structure similar to those of C. capolongoi or C. calaforrai n. sp., with a lateral lamella shorter than the apical cone ( Figs. 67, 68 View FIGURES 65–71 ). Partially sclerotized region of the tegument visible in the internal region of the cavity between the lamella and the cone, next to the flagellum ( Fig. 67 View FIGURES 65–71 ). Pedicellus with 5 long, bifid, spiralized macrosetae, 2 of which are in the distal region of the basal trunk of the apophysis, below the apical cone. Basal trunk with very setose tegument and 4 or 5 long, thin setae as long as the diameter of the apophysis.
Distal article of maxillary palp about 5 times longer than wide and 1.25 times longer than the penultimate article. Labial palp without remarkable features, each distal article with two basal groups of 4–5 basiconic sensillae, one on the inner side, one on the outer side.
L/W ratios of tibiae given in Table 2. Pro—and mesotibiae with 2 dorsal, 1 lateral and 4 ventral spines; metatibia, with 0–1 dorsal and 5 ventral spines.
Nota and urotergites I-IX typical. Posterior margin of tenth urotergite nearly straight, slightly concave ( Fig. 69 View FIGURES 65–71 ), with 7+10 sensory pegs extending from posterolateral lobes to the medial region of the lateral margin of the urotergite ( Fig. 70 View FIGURES 65–71 ); disc covered dorsally with sparse, thin, long setae.
Urosternites I-VIII with 1+1 discal, 1+1 submedian and 1+1 sublateral bifid macrosetae. Posterior margin of the eighth urosternite protruding, convex, rounded and slightly acute at its apex ( Fig. 71 View FIGURES 65–71 ). Parameres relatively short, with length-width ratio about 4.1, shorter than the ninth stylets ( Fig. 72 View FIGURES 72–75 ).
Cerci with 7+7 sensory pegs, 2 in each basal segment and 1+(1–2)+(1–2)+ 1 in the second division ( Figs. 73, 74 View FIGURES 72–75 ). Cerci in medial portion with very long bothriotricha, more than five times longer than width of the appendage. Paracercus with 5 acute pegs medially and 2 additional pegs laterally ( Figs. 73, 75 View FIGURES 72–75 ).
Female unknown.
Etymology. This species is called “ diania ” after the Latin name "Dianium" of the municipality of Denia (likely derived from the name of the Roman goddess Diana), in which the cave where this new taxon was found is located.
Remarks. Although only one specimen of C. diania n. sp. was available, there is no doubt that this troglobitic species is clearly different from all previously known Coletinia species. Compared to all of the species in the “ capolongoi ” group, C. diania n. sp. has a higher number of sensory pegs on the tenth urotergite and in the terminal filaments. The specimen is beginning the moulting process, but these structures are not duplicated. The only Iberian species with a comparable number of sensory pegs in the cerci is C. longitibia n. sp. from the north of Valencia province, which bears 6 pegs. Unfortunately, the paracercus of this species is broken, and only one spiniform peg can be seen in its basal segment. Nevertheless, this species is different from C. diania n. sp. in additional features (see Tables 2–4). The most closely related species seems to be C. capolongoi , but C.diania n. sp. is smaller: a specimen of C. capolongoi of 11.2 mm (the length of the C.diania holotype) is clearly a young specimen that has not developed the complete number of sensory pegs on the tenth urotergite and terminal filaments. Even when these pegs are well developed (in a male 14–15 mm long), the number of pegs in C. capolongoi is lower (4–6 on the tenth urotergite, 4–6 on the cerci and 0–5 on the paracercus).
