Antennal segment I with 14–16 setae. Sensory organ of antennal segment III with five papillae, two sensory rods, two sensory clubs (one with finger­shaped projections from the central axis and the other with laminated projections) and five guard setae (in a specimen there is an additional papilla: Fig. 5 C). Microsensillum at the level of the guard setae. Antennal chaetotaxy as in Figs. 3 B–C. Labium type A (papilla A thickened), but external E papilla smaller than the other (Fig. 7 A) (nomenclature according to Fjellberg 1998). Clypeal/prelabral/labral formula: 4 / 4 / 342 (Fig. 7 B), usual of some Onychiuridae species (Yoshii 1976; Fjellberg 1998). Head chaetotaxy in Table 1. Thoracic tergite I with three rows of setae; thoracic tergites II–III with seven rows of setae and 1 + 1 microsensilla (Fig 2 A, Table 2). Leg III longer than I or II. Tibiotarsi I and II with 25–28 setae in 3–4 whorls. Tibiotarsi of leg III with 24–30 setae in 4–5 whorls (Fig. 3 A, D). Tibiotarsi distal whorl with 11 setae, two of them slightly blunted. Setae number of each whorl constant (Table 3). Pretarsum with 1 + 1 setae. Claw inner tooth located at 65–70 % of inner edge. Empodium with basal lamella, narrowed towards the apex and slightly longer than claw (Fig. 3 D). Dorsal abdominal chaetotaxy in Table 4. Ventral tube with 12–21 latero­apical setae. Male genital plate very voluminous, with the aperture on the posterior part, very small in relation to organ size, with 120–170 small setae and 4 + 4 of these setae closer around the genital opening (Fig. 5 C). Female genital plate with 1 + 1 small setae on posterior valve and 29–38 longer setae on anterior valve, although this character depends on the size of the specimen (Fig. 6 D).

There are no parapseudocelli. Two pseudocelli on each subcoxa. Dorsal pseudopores formula: 10 /011/ 1111 (Figs. 2 A–B). Ventral pseudopores formula: 00/ 111 /0000 (Fig. 8). Pseudopores circular, without chitinized border, rounded by 7–10 granules (Figs. 6 A–B, 6 D). Derivatio nominis The new genus and new species are dedicated, “in memoriam”, respectively to R. Yoshii (Japan) and P. Bellinger (United States). Biology Yoshiiphorura bellingeri new species may be a troglophile species found in these caves, probably occurring in the fractures of the dolomitic structure of the Gador mountain range. It is present throughout the year, though less frequently in Simarron II during the dry season. It was captured in traps and by hand throughout both caves, an thus does not seem dependent on bat guano. The temperature in boths caves range from 11.3 ºC to 13.0ºC (Corraliza) and 11.9 ºC to 12.8 ºC (Simarrón II). Both caves have a poor vertical dimension. This is in accordance with the occurrence of other troglophile species (Table 5). Acherontiella xenylliformis Gisin, 1952 has been found in caves in Maroc and Algeria (Thibaud 1967), and in soil beneath Eucalyptus globulus Labill. in Portugal (Gama et al . 1995). Mesogastrura ojcoviensis (Stach, 1918) is frequent on the nest of the vole Microtus nivalis, (Martins, 1842) and on bat guano when captured in caves. Arrhopalites pygmaeus Marlier, 1942 is an edaphic and troglophile species abundant in Europe, and in caves in the Iberian Peninsula; the type material was obtained from bat guano (Bretfeld 1999). Arrhopalites elegans Cassagnau & Delamare, 1953 has been found in caves and open habitats (Massoud and Thibaud 1973). Oncopodura sp. near O. delhezi Stomp, 1974 may be troglobitic Collembola. Troglopedetes machadoi Delamare, 1946 was described from caves in Portugal. Deuteraphorura ghidinii (Denis, 1938) is an edaphic and troglophile species found from Switzerland to Maroc. Gisinurus malatestai Dallai, 1970 is an edaphic and troglophile species described from Italy, and occurs in different habitats in France, Spain and Mediterranean and Macaronesian islands. species Corraliza cave 27 ­Feb 18 ­Mar 7 ­May 21 ­May 15 ­Jul 28 ­Jul 13 ­Oct 29 ­Oct 19 ­Nov 23 ­Dec D T D T D T D D T D D T Arrhopalites elegans 1 13 Cassagnau & Delamare Debouteville, 1953 Arrhopalites pygmaeus 8 1 (Wankel, 1860) Arrhopalites sp. 3 (juvenile) Isotomiella sp.
