Figs 1–2, 5–24; Tabs 1–3
Material examined. 12 specimens in slides from six localities located at the “Serra Marina, “Serra del Montnegre and “Serra del Catllaràs mountains (Barcelona province, Spain) (Tabs 1 and 2). One specimen of the lot LP130 (slide code CRBA 10695), and one specimen of the lot LP137 (slide code CRBA 10696) saved in the collection of the Centre de Recursos de Biodiversitat Animal, Faculty of Biology, University of Barcelona (http:// www.crba.ub.edu); other specimens kept in the E. Mateos’ slides collection.
Other material. 125 specimens preserved in absolute alcohol and kept in the E. Mateos’ collection (Tables 1 and 2).
Description. Adult body length (without head and furca) 0.9–1.2 mm. Mesothorax not projecting over the head. Body dorsoventrally compresed with grey-orange background color. Blue pigment only present on ant.II–IV (with increasing colour intensity towards the distal part of each segment), and cx.I–III; densely black pigmented ocular areas (Fig. 1). Some individulas have blue pigment in the mid-dorsal head. The foremost part of the eyepatches connected by a pigmented band (Fig. 2).
Antenna without scales. Ratio antenna:cephalic diagonal 1.1–1.7. Ratio ant.I:II:III:IV as 1:2:2:3. Basis of ant.I dorsally and ventrally with three microchaetae arranged in triangle (Fig. 5). Ant.II dorsally with one distal rod-like sensory seta (Fig. 6). Ant.III organ composed of two subcylindrical sensory rods partially covered by an integumentary fold, and with three lateral sensory setae (Fig. 7). Without apical ant.IV bulb.
Ciliated prelabral setae and smooth labral setae in typical number 4/5,5,4; setae of apical row thicker than those in other rows. Inverted V-shaped labral apical intrusion (Fig. 8). Four rounded smooth labral papillae. Lateral process (sensu Fjellberg 1999) of outer labial papilla curved, tip not reaching the apex of the papilla (Fig. 9). Maxillary palps with two lobal smooth setae and three sublobal smooth setae (Fig 10).
Labial anterior row formed by five smooth setae (a1–a5); posterior row formed by ciliated setae with formula [M1*] M2R*EL1L2; seta M1 present only in four out of twelve examined individuals, setae R and M1 half in length of other setae (marked with *). Ventral cephalic groove with 4+4 ciliated setae (Fig. 11).
Dorsal macrochaetae formula such as R0R1s R1R2STSo/10/0101+2 (Fig. 12); a pair of supplementary macrochaetae R1s between R0 and R1 present. Maximum number of macrochaetae A between ocular areas 9+9 (Fig. 13). Interocular chaetotaxy with ciliated setae (s, t, p), and 2–3 scales (Fig 14). Eyes G and H somewhat smaller than the other. Th.I chaetotaxy as in Fig. 15; seta p3 ciliated macrochaeta; anterior margin of the tergite bordered with ciliated macrochaetae. Abd.II–III chaetotaxy as in Figs 16–17; abd.II seta ml absent; abd.III setae ll and d3 absent; abd.III seta p8p smooth mesochaeta. Abd.IV chaetotaxy as in Fig. 18 -a; trichobothrium T2 without accessory seta s; seta D1 ciliated and double in length than setae a and m (Fig. 19); seta E4p ciliated macrochaeta in two out of 12 examined individuals, smooth mesochaeta on the other 10 (Fig. 18 -b); seta Fe4 smooth mesochaeta; macrochaeta E3 inserted below F2; ratio C1-B5/B5-B6 as 1.2–1.6; dorsal macrochaetae of two distinct morphologies: B5, B6, C1, D3, E2, E3, E4, F1, F2, F3 broader and with broad socket (bcm in Fig. 16 -b); T6, T7, D2, De 3, E1, E4p (depending on the specimens), Fe5, E4p2 shorter or longer but always thinner and with socket of minor diameter (tcm in Fig. 18 -b).
Ventral tube without scales; 9+9 ciliated setae on anterior side (Fig. 20); 7+7 ciliated setae on posterior side, and each lateral flap with a maximum of 7 ciliated setae and 2 smooth setae (Fig. 21).
Legs without scales. V shaped trochanteral organ (leg III) with a maximum of 16 smooth straight setae arranged in triangular shape (Fig. 22). Unguis with basal pair of teeth at 50% of the inner edge, and with one inner teeth at 67% from the base of the inner edge respectively. Unguiculus lanceolate with smooth outer margin. Spatulate tibiotarsal tenent hair (Fig. 23).
Furca without scales on dorsal surface. Mucro bidentate; mucronal basal spine without spinelet. Ratio manubrium:dens:mucro as 17:16:1. Manubrial plate with two pseudopora, 2 inner setae, and 3–4 outer setae (Fig. 24).
