2. Body length less than 4.0 mm; head, when viewed laterally, with gula and posterior half of buccula only slightly differing from remainder of head in coloration (Fig. 13); endosoma with dextrolateral margin of DSS straight (Fig. 23); left paramere distinctly curved, with apical process, when viewed dorsally, with sinistrolateral margin distinctly convex medially (Fig. 25–25).................................................................................. C. castaneus (Carvalho)
- Body length more than 4.0 mm; head in lateral view mostly dark castaneous, with contrastingly yellow gula and posterior half of buccula (Fig. 18); endosoma with dextrolateral margin of DSS convex medially (Fig. 51); left paramere only weakly curved, with apical process, when viewed dorsally, with sinistrolateral margin moderately rounded, not distinctly curved medially (Figs. 52–53)................................................................... C. laevigatus Wolski sp. nov.
3. Hemelytra uniformly dark castaneous to almost black, without any pale patch on apex of corium (Figs. 2–3, 5, 9); DSS relatively long, longer than its width (Figs. 28, 40, 62, 67); ML strongly reduced or absent (Figs. 28, 40, 62, 67); lateral and medial sclerites distinctly developed (Figs. 28, 40, 62, 67)........................................................... 4

5. Antennal segment II entirely brown, without pale annulation apically (Carvalho & Gomes 1971); endosomal lateral sclerite (LS) with apical half crescent-like, mesial sclerite bifurcate basally, spindle-like apically, mesial lobe (ML) absent (Fig. 62).......................................................................................
