Alticini

Alticini are small to medium-sized Coleoptera in the family Chrysomelidae, subfamily Galerucinae. The jumping apparatus is localized in the hind legs and formed by the femur, tibia, femoro-tibial joint, modified metafemoral extensor tendon, extensor ligament, tibial flexor sclerite, and extensor and flexor muscles. The metafemoral extensor tendon has a dorsal lobe and ventral lobe; the extended arm of the dorsal lobe may be moderately elongate and slightly depressed. The hind tibia bears a simple, moderately elongate apical spur. The pronotum is often sub-trapezoidal, distinctly transverse, and rounded laterally. Frontal grooves are distinctly impressed, extending from the upper ocular margin to the antennal socket. Antennae are slightly shorter than half the body length. Elytra are indistinctly elongate, entirely covering the pygidium, strongly arcuate laterally, and jointly rounded apically. The surface may have punctures that are slightly elongate and deeply impressed on a sub-smooth surface. The aedeagus is distinctly and evenly curved in lateral view. The spermatheca has a sub-cylindrical basal part, narrower towards the distal part, with a thin, uncoiled ductus.
