2. Pronotal carina almost entirely absent, barely visible on humeri only ( Fig. 4A View FIGURE 4 ). Tegula small and not expanded posteriorly, maximum width in anterior third; parategula broad and subtriangular ( Fig. 4D View FIGURE 4 ). Propodeum entirely vertical, without a dorsal horizontal face behind metanotum ( Fig. 13D View FIGURE 13 ). T 1 in lateral view evenly and strongly convex above, much higher in the middle than at base and apex; T2 with V-shaped depression on disc; apical lamella of T2 and T3 preceded by a strong preapical bulge ( Fig. 13I View FIGURE 13 )............................................................................ C. madli Gusenleitner
-. Pronotal carina more developed, at least on lateral thirds of pronotal margin ( Fig. 7A View FIGURE 7 ). Tegula large and broadly expanded posteriorly, maximum width in posterior half; parategula narrow and digitiform ( Fig. 7D View FIGURE 7 ). Propodeum bulging dorsally, with a short dorsal horizontal face behind metanotum ( Fig. 13E View FIGURE 13 ). T 1 in lateral view abruptly expanded basally, then of regular height for most of its length; T2 not depressed on disc; only apical lamella of T2 preceded by a shallow preapical bulge ( Fig. 13J View FIGURE 13 ).. ................................................................................................... 3
3. Sculpture of head and mesosoma sparser and shallower; clypeus almost impunctate, with very fine sparse punctures ( Fig. 7C View FIGURE 7 ); tegula micropunctate with few barely visible punctures ( Fig. 7D View FIGURE 7 ); dorsolateral faces of propodeum with interspaces mostly flattened and distinct. Occipital carina weak, barely visible on vertex. Transverse carina of metanotum blunt. Apical lamella of T3 preceded by a series of deep and well-marked punctures ( Fig. 13C View FIGURE 13 )....................... C. rhombicus Gusenleitner
-. Sculpture of head and mesosoma denser and coarser; clypeus coarsely and densely punctate; tegula with large deep punctures ( Fig. 11 View FIGURE 11 ); dorsolateral faces of propodeum with interspaces reduced to irregular ridges. Occipital carina strong, well developed on vertex. Transverse carina of metanotum sharp. Apical lamella of T3 preceded by a series of shallow and not marked punctures.................................................................... C. suboscurus (Giordani Soika)
4. Propodeum without a horizontal face behind metanotum ( Fig. 13F View FIGURE 13 ).............................................. 5
-. Propodeum with a horizontal face behind metanotum distinctly separated from posterior vertical face ( Figs. 13G–H View FIGURE 13 )...... 6
5. Head and mesosoma more sparsely punctate, interspaces shiny and about as long as half puncture diameter ( Figs. 3A–C View FIGURE 3 ); tegula micropunctate and shiny ( Fig. 3D View FIGURE 3 ). Pronotum with a distinct separation between dorsal and anterior faces, pronotal carina developed on lateral thirds; anterior face of pronotum with sparse punctures medially. Metanotum without an anterior face, transverse carina slightly produced at extreme sides. Propodeum convex above apical deep concavity. T1 shorter and wider, 1.4× as long as apically wide; extreme base with a shallow transverse ridge; preapical furrow shallow ( Figs. 3A–B View FIGURE 3 )........................................................................................... C. flavorufus sp. nov.
-. Head and mesosoma more densely punctate, interspaces matte and mostly reduced to narrow ridges ( Figs. 9A–D View FIGURE 9 ); tegula densely microreticulate and matte ( Fig. 10A View FIGURE 10 ). Pronotum without a distinct separation between dorsal and anterior faces, pronotal carina developed on lateral fifths only; anterior face of pronotum with coarse and dense punctures medially. Metanotum with a distinct anterior face, transverse carina produced in two wide rounded lobes. Propodeum entirely oblique from base to apex, except very shallow apical concavity. T1 longer and narrower, 1.8× as long as apically wide; extreme base without transverse ridge; preapical furrow deep ( Figs. 9A–B View FIGURE 9 )................................................. C. sollicitus (Giordani Soika) View in CoL
6. Basal margin of clypeus strongly raised in median third and margined laterally by sharp ridges ( Fig. 8C View FIGURE 8 ). Horizontal face of propodeum posteriorly margined, angularly separated from posterior face ( Fig. 13H View FIGURE 13 ); submarginal carina completely fused to strongly developed inferior carina, with a very short and barely visible projection above valvula ( Fig. 8B View FIGURE 8 ). T1 with basal transverse carina angled in the middle; apical lamella of T2 not pigmented and not preceded by thickening of tergite ( Figs. 8A–B View FIGURE 8 ). Larger size, body length 7.0 mm.................................................... C. scrobalis sp. nov.
-. Basal margin of clypeus not or shallowly raised, without sharp lateral ridges ( Figs. 1C–D View FIGURE 1 , 5C–D View FIGURE 5 ). Horizontal face of propodeum not margined, transition to posterior face rounded ( Fig. 13G View FIGURE 13 ); inferior carina not developed and submarginal carina with a long and pointed projection above valvula ( Figs. 1A–B View FIGURE 1 , 5A–B View FIGURE 5 ). T1 without basal transverse carina; apical lamella of T2 largely pigmented at base and preceded by a thickening of tergite ( Figs. 1A–B View FIGURE 1 , 5A–B View FIGURE 5 ). Smaller size, body length less than 6.0 mm..................................................................................................... 7
7. Gena in dorsal view sinuate in front of posterior margin ( Fig. 13K View FIGURE 13 ); occipital carina higher and lamellate on most of gena. Pronotal carina weaker on humeri, not pointing forward ( Figs. 1A View FIGURE 1 , 13K View FIGURE 13 ). Propodeum entirely black, at most with a narrow dark red margin at base of projection of submarginal carina ( Figs. 1A–B View FIGURE 1 ). Punctures of head and mesosoma denser, interspaces much narrower than puncture diameter ( Figs. 1A–D View FIGURE 1 ). Male: F11 apically pointed and reaching apex of F8. Female: clypeus ferruginous, punctures on disc of basal half coarse and dense, interspaces shorter than puncture diameter ( Fig. 1D View FIGURE 1 ); legs entirely brownish red ( Fig. 1B View FIGURE 1 )......................................................... C. bekilyensis (Giordani Soika) View in CoL
