Calosoma (Caminara) imbricatum Klug, 1832

Each elytron of C. imbricatum has 16 intervals, it is to say that only one tertiary interval exists on each sides of a secondary one (triploid type). C. imbricatum is the only species of Caminara that has this model of sculture of the elytra.
Does exist in South West Africa a population (hottentottum) that seems to be isolated and that is well characterized by its slimmer body shape and by a lively metallic color, but in the remaining area in which it is diffused, C. imbricatum presents a very scarce differentiation, concerning some variation in size and body shape, or the greater or lesser visibility of the sculpture of the elytra.
However, in the north east of the distribution area (Central Asia and north of China, up to Mongolia) we find a population (deserticola) that has a larger and more elongated body with less raised elytral sculpture. Semenov (1897) described deserticola as a separated species and Breuning (1927) and Jeannel (1940) followed this interpretation. At last, Mandl (1970: 62) dealt with deserticola as a mere subspecies of C. imbricatum, along with others he had described in the meantime (1953, 1967, 1970).
In our opinion, except hottentottum and deserticola, the remaining populations of C. imbricatum, that are widespread from Cabo Verde archipelago through the Sahelian zone to Arabia, Syria, Iraq, Iran, Pakistan, do not present significant differences except for a slight variation in size. However, from North of the Indian Peninsula has been described another population, also of relatively large size, but stouter and with a still more flattened sculpture of elytra (andrewesi), that possibly also could be maintained at subspecies level.

Length 15-22 mm. What we consider as the typical populations are the ones with individuals of small or medium size having finely punctate head and pronotum, elytra in oval widened, and elytral sculpture with scaly intervals. The upper body is black, with faint bluish reflexes.
C. imbricatum imbricatum continuously spreads in Africa, excluding the area of equatorial forest, throughout the Sahelian zone, Algeria, Libia, Senegal, Mali, Niger, Chad, to Sudan, Eritrea, Djibuti, Ethiopia, Somalia, Kenya. It is present in Cabo Verde islands but not in the Canary islands and Andrewes' quote (1929: 64) for Tenerife must be considered incorrect (Machado, 1992: 87).
In East Africa it is possible to find single specimens with slightly more wrinkled head and a little stronger elytral sculpture. On this basis Mandl (1968c: 128) described from Somalia the subspecies linnavuorii that he considered intermediate between the typical one and ottenttotum and that would be present throughout the Horn of Africa from Somalia to Kenya. However, the inconsistency of these characteristics does not seem to justify this subspecies.
In Kenya, the situation is more complicate. In north-eastern Kenya, we find some populations definitely referable to C imbricatum imbricatum and Breuning (1927: 221) reports the nominate subspecies from south west (Taveta, very close to the Tanzanian border). Jeannel (1940: 105) cites C. imbricatum hottentottum from the locality of Sultan Hamud in Makueni Province and Mandl (1970: 61) has attributed this citation to his C. imbricatum linnavuorii.
Still from Amboseli park, not far from Sultan Hamud, and from Karatu in Eastern Tanzania we have seen specimens with more pronounced characteristics of sculpture and color, very similar to C. imbricatum hottentottum. These specimens have more or less evident bronze reflections on the upper side of the body and rougher elytral sculpture than C imbricatum imbricatum.
One might conclude with Jeannel that C. imbricatum hottentottum is present in western Kenya (Bruschi, 2013: 76), and in Eastern Tanzania, or one might consider these specimens as simple individual variations within C imbricatum imbricatum. However, before definitevely deciding if these specimens are part of an omogeneous population and eventually which relationships there are between this population and C. imbricatum hottentottum, remain to explain the presence of specimens of the typical form in the same region of Kenya and the strange fact that so far no specimens of imbricatum have been found in the vast area between eastern Tanzania and Namibia.
Going to East, the roughness of the head and pronotum decreases and the elytral sculpture tends to flatten. We find populations variously named, but which can also be referred to the typical form and that live in the Arabic peninsula: Yemen, Kuwait, Saudi Arabia, Oman, Qatar and Iraq (which Mandl considers all as C. imbricatum arabicum), Syria, southern Iran (C. imbricatum loeffleri), up to Pakistan. The populations of the south eastern Pakistan someway accentuate these characteristic and look as transitional to C. imbricatum andrewesi.

Caminara imbricatum subsp. hottentota Jeannel, 1940: 104

Length 18-20 mm. This population is distinguished from the others because of head and pronotum with large punctures and with deep, transverse, wrinkles and because of the rougher sculpture of the elytra. Moreover, C imbricatum hottentottum in all cases has the upper part with bronze reflexes (not bluish as in the other populations).
C imbricatum hottentottum is known living in Namibia and South Africa, and most probably should be restricted to these countries.
However, it should be noted that, coming back to the idea firstly expressed by Jeannel (1940: 105), Hackel & al. (2016) consider the specimens from South West Kenya (Amboseli park) as C. imbricatum hottentottum, while we prefer to deal with them them as simple individual variations within C imbricatum imbricatum, as we have already argued above.
Finally, Hackel & al. (2016) also regard the holotype of C. aetiops from Niger as a specimen of C. imbricatum hottentottum (see more details when specifically dealing with C. roeschkei). Yet, in the latter case, the Jeannel's holotipe should be considered as having an incorrect locality label, as, up to now, no more specimens having the same characteristics of the holotype have never be found in the place, while the typical form is relatively common throughout Niger.

Length 22-28 mm. Calosoma deserticola was described by Semenov (1897) as a species and maintained as such by Breuning (1927), albeit doubtfully, and by Jeannel (1940) who even included it in a different genus (Campalita). It has been considered by Lapouge (1932) and later by Mandl (1969) as a mere subspecies of C. imbricatum. In fact C. imbricatum deserticola is quite similar to the typical C. imbricatum imbricatum and only can be distinguished because of the constantly larger body size, the more flat sculpture of the elytra and by the black colour without bluish or bronze reflections.
The populations of Central Asia mostly have larger body and less expanded elytra, but going east (Mongolia) the individuals became smaller and stouter, although maintaining the same model of elytral sculpture. Obidov (2005: 5) considered the Mongolian population as a distinc taxon (C. deserticola augustasi). The diagnosys has been based on feeble differences: the lesser size, the more evident sculpture of the head, pronotum and elytra, the larger foveae on the primary intervals, and the slightly thicker aedeagus apex. These differences, apart from the different shape of the aedeagus, a little exaggerated in the original description, are constant but barely perceptible, and in our opinion do not deserve to be taken into consideration to further subdivide such a variable species as the complex of C. imbricatum is. Thus we can simply conclude that C. imbricatum deserticola in Mongolia is represented by an isolated, but very little differentiated, population. As for the populations of northeren Iran, south western Turkmenistan and possibly of western Pakistan, these could represent a transition between C. imbricatum deserticola and the typical form, as supposed by Breuning (1927: 224).

Calosoma (Caminara) imbricatum ssp. loeffleri Mandl, 1953: 57 (partim)

Length 20-22 mm. Chaudoir (1869: 368) cited one specimens of a Calosoma coming from India which he had found to be very similar to C. imbricatum and which he thought might be tentatively identified as the Calosoma orientale previously described by Hope. Breuning (1927: 223), once he ascertained the presence of a population of C. imbricatum in India, kept the name Calosoma imbricatum orientale for it and so endorsed the misunderstanding of Chaudoir. Only later, Breuning (1928: 95) correctly identified C. orientale of Hope with the species that Chaudoir (1869: 368) had named C. squamigerum, and for this reason he proposed for the Indian population of C. imbricatum the new name andrewesi.
C. imbricatum andrewesi consists of populations of a relatively larger size, with a stout body and flattened elytral sculpture. The colour of the upper body is a dull, not metallic, black.
Few old captures are cited from Nort-Eastern India (Bengal, Assam), but in recent times some more specimens were found in the Western Indian State of Rajasthan and in Pakistan on the borders of the Thar desert. Anyway reliable data are scarce and, as for the Indian sub-continent, C. imbricatum seems to be quite rare or at least quite difficult to detect.

Examined specimens and literature’s data
India. Assam (holotype, Breuning, 1928b: 95); North of Bengal Presidency (Chaudoir, 1869: 368); Rajasthan: Jaipur (SB), Jodhpur (sub imbricatum imbricatum, Kumar S. et al., 2022: 22263), Mount Abu (RS), between Bikaner and Jaisalmer (RS), Thar Desert (sub loeffleri, Mandl, 1970: 63).
Pakistan. Sindh prov. Tharparkar dist (SB).

Notes: As the other populations of the same species, C. imbricatum andrewesi is winged and attracted to light at night. Active individuals were captured in July.
The subspecies has been named after Herbert Edward Andrewes (1863 - 1950) an English entomologist, specialist in Carabidae, that worked at the Indian Forest Service and later at the Natural History Museum in London.
