1. Pronotum with sublateral carina in posterior angles ......................................................................... 2
– Pronotum without sublateral carina in posterior angles ................................................................... 3
2. Pronotum more convex, with equally rounded sides; pronotal sublateral carina close to lateral carina; oblique keel on each elytron near scutellar shield distinct ( Fig. 4C View Fig ); parameral apical lobe short, equally rounded ................................................................................. L. modestus (Boisduval, 1835)
– Pronotum less convex, more elongate, with widely rounded sides; pronotal sublateral carina distinctly far from lateral carina; oblique keel on each elytron near scutellar shield obsolete ( Fig. 4D View Fig ); parameral apical lobe elongate, narrowly rounded ................................
