Subgenus Caminara Motschulsky, 1866
Caminara Motschulsky, 1866: 303 (type imbricatum Klug)
Callistrata Motschulsky, 1866: 306 (type granulosum Motschulsky, 1844 = denticolle Gebler, 1833)
Catasoma Lapouge, 1929: 10 (type olivieri Dejean, 1831)
Together Caminara Motschulsky, 1866 and Campalita Motschulsky, 1866 belong to the Calosoma that have the ligula of the endophallus sclerified ("Calosomes ongulés" sensu Jeannel, 1940). Furthermore, always according to Jeannel (1940), they fall in the phyletic line Castrida-Caminara, that he considers originated from the ancient Afro-Brazilian plateau.
With the exception of American Castrida Motschoulsky, 1866, all other subgenera in the group have the metaepisternum with fine and dense punctuation. Caminara and Campalita differ from Charmosta Motschulsky, 1866 and Ctenosta Motschulsky, 1866 because they still have a seta close to hind angles of the pronotum. The further distinction between them was based on the evolutive characteristics of the sculpture of the elytra, that Jeannel considered as the fundamental element for the reconstruction of the phylogeny of the group. Only two species (C. imbricatum Klug 1832 and C. chlorostictum Dejean 1831) were included in Caminara by Jeannel (1940.
Conversely Basilewski (1972: 37), coming back to the approach of Breuning (1927-28), and of other later authors (Khryzhanowsky 1962, Mandl, 1970), considered the shape and the chaetotaxy of male's mesotibiae as the most important characteristics. So he attributed to the subgenus Caminara all species with the mesotibiae of both sexes only slightly curved and free of brush on the inner side.
To-day most of the authors agree with the interpretation of Basilewsky (1972), even though, in the more recent Catalogue by Bousquet et al. (2003: 120-121) all the species that following we consider Caminara (except imbricatum) are put together, without any distinction, inside Campalita.
According to the prevalent opinion that we share, Caminara includes six species with 16 or 22 striae on each elytron ("triploïde" or "pentaploïde" type): C. imbricatum Motschulsky, 1866 and C. olivieri Dejean, 1831, widespread in Africa (Equatorial and Southern Africa for C. imbricatum and Mediterranean for C. olivieri), as well as in Arabian Peninsula and India; C. reitteri Roeschke, 1896, found in Central Asia only; C. davidis Géhin, 1885 from the Himalaya to the mountains of central China over 2000-2500m of altitude (to which C. arrowianum, described by Breuning (1927) on a single specimen of Tibet, probably must be assimilated); and finally the northernmost C. denticolle Gebler, 1833 from the Balkans to the Urals and to eastern Siberia.
