Subgenus Campalita Motschulsky, 1865
Campalita Motschulsky, 1865: 304 (type maderae Fabricius, 1775)
Cosmoplata Motschulsky, 1865: 305 (type aeneum Motschoulsky, 1859 = chinense Kirby, 1818)
Eremosoma Lapouge, 1929: 10 (type algiricum Géhin, 1885)
Campalita belongs to the Calosoma that have the ligula of the endophallus sclerified ("Calosomes ongulés" sensu Jeannel, 1940).
According to Jeannel (1940) Campalita falls in the phyletic line Castrida-Caminara, that he considers originated from the ancient Afro-Brazilian plateau. In this phyletic line in most cases a basal seta is still present close to hind angles of the pronotum.
With the exception of American Castrida, all other subgenera in the group have the metaepisternum with fine and dense punctuation. Caminara and Campalita differ from Charmosta and Ctenosta because in their case the basal seta of the pronotum is always present. The further distinction between them was based by Jeannel (1940) on the evolutive characteristics of the sculpture of their elytra, considering this as the fundamental element for the reconstruction of the phylogeny of the group. In Campalita were included species that have two tertiary intervals on each sides of a secondary one ("pentaploïde" type), or species, as Campalita maderae - auropunctatum, that have a tendency to switch to this type duplicating the tertiary intervals.
Later Basilewski (1972: 35), coming back to the approach of Breuning (1927-28), and of other authors (Khryzhanowsky 1962, Mandl, 1970), considered the shape and the chaetotaxy of male mesotibiae as the most important characteristics. The species of the Campalita subgenus (sensu Basilewski, 1972), can have 16 or 22 striae on each elytron ("triploïde" or "pentaploïde" type) but are differentiated from the ones belonging to the Caminara subgenus by the male mesotibie strongly arched and with a brush on the inside.
The subgenus Campalita is present with three species in the palearctic region, from the Mediterranean to Siberia, but one species chlorostictum is found in the paleo-tropical region. Are exclusively palearctic: algiricum from Central Asia to the Mediterranean, maderae, which follows in part the same path but is also present in central and northern Europe and occupies the western Himalayan range (maderae indicum), and chinense from China, eastern Siberia, Japan.
