Subgenus Apterodela Rivalier, 1950

Description. TL = 12.4–18.9 mm (mean = 16.16 mm, n = 95).

Labrum unidentate in both sexes ( Figs 63–82 , 85–87, 90–95, 98–100 ), rarely almost three-dentate in females ( Figs 88, 89 ), or clearly tridentate in males ( Figs 83, 84 ), with 3–11 long submarginal setae.

Pronotum indistinctly longitudinal or sub-quadrate ( Figs 103–135, 138–140 )—PW/PL = 0.81–1.09 (mean = 0.99, n = 204) ( Fig. 269 ); wingless ( Fig. 143 ).

Elytra with narrow and sloping shoulders, EW/EHW = 1.41–1.86 (mean = 1.57, n = 204) ( Fig. 269 ); in one species with deep subapical sinuate notch ( Figs 193–212 ), in the other species with poorly developed subapical sinuate notch ( Figs 155–162, 165–179, 183–189 ) or entirely lacking ( Figs 153, 154, 163, 164 ). White elytral pattern extremely reduced and presented by a small apical portion of humeral lunule (sub-humeral spot), a basal portion of apical lunule (supra-apical spot), and a short apical or centro-apical portion of middle band.

Internal sac of aedeagus with long cylindrical sharp mt ( Figs 237–241 , 251–255 , 258–262 , 265, 267, 271 ).
