Lepidocyrtus cyaneus Tullberg, 1871

Figs 4 , 5–25, 27 ; Tabs 1–3

Material examined. 16 specimens in slides from two localities located at the Ordesa National Park (Huesca province, Spain) ( Tabs 1 and 2 ). One specimen of the lot LP271 (slide code CRBA 10699), and one specimen of the lot LP277 (slide code CRBA 10700) 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. 109 specimens preserved in absolute alcohol and kept in the E. Mateos’ collection ( Tables 1 and 2 ).

Description. Adult body length (without head and furca) 1.0– 1.2 mm. Body dark blue pigmented on dorsal and ventral regions (including ventral tube); head light blue pigmented also on dorsal and ventral regions; blue pigment also present on ant.II–IV, cx.I-III, tr.I–III, and manubrium ( Fig. 4 ).

All morphological and chaetotaxic characters match those explained for L. lanuginosus , with the following differences: Ratio antenna:cephalic diagonal 1.2–1.7. Labium chaetotaxy [M1*] M2R*EL1L2, M1 present in 13 out of 16 examined specimens. Head with a maximum of 10+10 macrochaetae in row A. Abd.II seta ml present on four out of 16 examined specimens ( Fig. 25 ) (usually this seta is present on one side of the body and absent on the other side). Abd. IV seta Fe4 ciliated macrochaeta ( Fig. 18 -a). Ventral tube with a maximum of 8 ciliated setae and 2 smooth setae on lateral flaps. V-shaped trochanteral organ formed by a maximum of 17 smooth setae. Unguiculus with outer edge smooth (in 13 examined specimens), or finely serrated (in 3 specimens) ( Fig.27 ).
