Studied material. Córdoba, Los Villares, 11 July 2007, 1 male and 1 juvenile ( UCO, Ref. Z 2174); Córdoba, Hornachuelos, M. Baena leg., 19 October 1991, 2 males ( UCO, Ref. Z 2075); Córdoba; Palenciana, 5 December 2002, 2 juveniles ( UCO, Ref. Z 2176) ;

Córdoba, Alcolea, 10 September 2002, 2 males (1 dissected for SEM studies) and 2 juveniles ( UCO, Ref. Z 2175). The type material from Peal de Becerro (Jaén) also was re-examined .

Descriptive remarks. The availability of additional specimens of this species (some edaphic and others from caves) has enabled us to widen our knowledge of its intraspecific variability and geographic distribution. One specimen was used for SEM studies in order to make the description of C. tinauti more precise and to compare it with the remaining Coletinia spp. Characteristics sufficiently described in the original description are not commented on here, except those that require correction or redescription to be compared with related new species or for inclusion in the identification key presented below.

The body shape ( Fig. 1B ) is subcylindrical (length up to 11 mm) and more slender than C. mendesi (compare with Fig. 1A ). The macrosetae of C. tinauti show a low degree of spiralization ( Fig. 153 ). The antennal apophysis of the male pedicel is typical of the Mediterranean species of the group “ capolongoi . ” Its apical part reaches the third or fourth joint of the flagellum. The subapical plate-like expansion can be observed clearly with SEM; in the original description, it was interpreted as folds with an internal bulb, which is how it appears with OM ( Fig. 154 ). The lateral projection and the glandular cone define a cavity with smooth tegument and the projection is folded forming a tectum (roof) that covers the cavity ( Figs. 155–157 ). The tegument of the trunk of the apophysis appears to be more pilose than in other related species, and its scale-like rugosities are not as marked. However, detailed examination with OM of additional specimens revealed that this characteristics appears to be somewhat variable within this species. The female pedicel drawn in Molero et al. (1997, Fig. 4.1 ) does not exhibit the typical shape because it is collapsed, but does include the usual five macrosetae inserted into this antennal division.

The distal article of the maxillary palp is relatively short, about 5–5.75 times longer than wide and 1.15–1.45 times longer than the penultimate article.

L/W ratios of the tibiae are presented in Table 2; C. tinauti has shorter tibiae than related species, in which the metatibiae are approximately 4.5 times longer than wide. All of the tibiae have 1–3 dorsal, 1 lateral and 4–5 ventral spines, and sometimes 1–2 additional short ventrobasal spines (see Fig. 2.3 of the original description).

The tenth urotergite has a concave posterior border ( Fig. 158 ) and 4–6 sensory pegs. These pegs are similar to those of C. capolongoi , subcylindrical, with striated tegument and a ventroapical furrow where the striations converge ( Fig. 9B ). Setae irregularly cover the disc of the urotergite in both sexes. In females, the posterior border is slightly concave ( Fig. 159 ).

The eighth urosternite of the male protrudes, with its posterior border convex and rounded ( Fig. 160 ). Paramera are relatively short, about 4-5,5 times longer than wide ( Fig. 161 ). The subgenital plate of the female is approximately as long as wide at the base or slightly longer than wide, with a truncated and almost straight posterior border ( Fig. 162 ). The long ovipositor long has 18–20 divisions and extends beyond the tip of the ninth stylets by 2.4–2.7 times their length. Cerci of the male have 2–6 acute sensory pegs; the paracercus lacks true pegs but possesses 1 or 2 short spines ( Fig. 163 ).
