Subgenus Campalita Motschulsky, 1865

Campalita Motschulsky, 1865: 304 (type: maderae Fabricius, 1775)
Cosmoplata Motschulsky, 1865: 305 (type aeneum Motschoulsky, 1859 = chinense Kirby, 1818)
Campolita Gehin 1885: XXXII (erroneusly ascribed to Motschulsky, 1865 and proposed as replacement name for Campalita)
Campolyta Bedel 1895: 18 (quotes Gehin 1885 and repeats the mistake)
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), and falls in the phyletic line Castrida-Caminara, that Jeannel (1940) 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.
Inside his genus Campalita Motschulsky (1865: 304) had listed azoricum (= olivieri) together with maderae and some other species now considered as populations of maderae. Breuning (1927: 191) considered that the characters given for Campalita match exactly the ones of maderae and therefore this should be considered the type species of the genus. Jeannel (1940: 100) and the subsequent authors have been of the same opinion.
According to Jeannel (1940) the distinction between Campalita Motschulsky, 1866 and Caminara Motschulsky, 1866 should be based 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. So in Campalita were included species that have two tertiary intervals on each sides of a secondary one ("pentaploïde" type), or species, as Campalita maderae (Fabricius, 1775), that have a tendency to switch to this type duplicating the tertiary intervals.
Later Basilewsky (1972: 35), coming back to the approach of Breuning (1927-1928), and of other more recent authors (Kryzhanovskij 1962, Mandl 1970), considered the shape and the chaetotaxy of male mesotibiae as the most important characteristics. The species of the Campalita subgenus (sensu Basilewsky 1972), can also 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 mesotibiae strongly arched and with a brush on the inner side.
The four species of the subgenus Campalita, as previously defined, occupy areas included in the palearctic region, from the Mediterranean to Siberia, except C. chlorostictum Dejean, 1831 which is found in the afrotropical region and middle east. The palearctic species are C. algiricum Géhin, 1885 from Central Asia to the Mediterranean; C. maderae (Fabricius, 1775) which follows in part the same path up to the Himalayan range but is also present in northern China and central and northern Europe; and C. chinense Kirby, 1818, closely related to C. maderae and which substitutes it in China, eastern Siberia and Japan.
