- Forebody dark-brown to blackish-brown, as dark as the abdomen or nearly so; antennae brown to dark-brown............................................................................................3

2: posterior margin of tergite VIII distinctly emarginate in the middle (Fig. A00: 12); posterior margin of sternite VIII strongly convex (Fig. A00: 13); median lobe of aedeagus as in Fig. T98: 2.: posterior margin of sternite VIII more broadly incised in the middle (Fig. A00: 15); spermatheca as in Figs T98: 3-5. Cantabria: Pico de Tres Mares (Map 1)..................................................................................... C. pacei (TRONQUET)

-: posterior margin of tergite VIII almost truncate, not distinctly emarginate in the middle (Fig. A00: 8); posterior margin of sternite VIII moderately convex (Fig. A00: 9); median lobe of aedeagus as in Figs A00: 4-5.: posterior margin of sternite VIII more narrowly incised in the middle (Fig. A00: 11); spermatheca as in Fig. A00: 7. León: Sierra del Teleno (Map 1). ........................................................ C. feldmanni ASSING

3 Forebody with shallow, but distinct microsculpture and subdued luster. Punctation of pronotum extremely fine, barely visible, and rather sparse. Elytra longer, approximately 0.6 times as long as pronotum (Fig. A03: 3).: sternite VIII strongly convex posteriorly (Fig. A03: 5); median lobe of aedeagus with short and in lateral view subapically angled ventral process (Figs A 03: 7-10).: sternite VIII and spermatheca as in Figs A 03: 6, 11. Cantabria: Picos de Europa (Map 1).............................. ............................................................................................................. C. tenebrosa ASSING

- Forebody glossy, microsculpture very shallow, visible only at high magnification. Pronotum with distinct and rather dense punctation. Elytra shorter, approximately 0.5 times as long as pronotum ( Fig. 1 ).: sternite VIII weakly convex, almost truncate posteriorly ( Fig. 4 ); ventral process of aedeagus conspicuously long and in lateral view arched ( Figs 5-6 ).: unknown.
