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 ); 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 ); parameral apical lobe elongate, narrowly rounded ................................

Pronotum longer than wide when width measured along half ......................................................... 4 – Pronotum about as long as wide or wider when width measured along half ................................... 5 4. Body covered with wide scale-like setae; pronotal punctation dense; pronotal posterior angles short, less sharp; punctures rough, large, often contiguous ( Fig. 4B ) ............. L. punctatus (Herbst, 1779) – Body covered with thick hair-like setae; pronotal posterior angles distinct, long, sharp; pronotal punctation less dense; punctures smaller, separated by about 0.5–1 times their diameter ( Fig. 4 E– G) ...........................................................................................................
