Calosoma (Carabops) burtoni Alluaud, 1913

Calosoma Burtoni Alluaud, 1913: 80 (type locality: "région du lac Tanganyika"); type material 1 ♂ 2 ♀ ♀, lectotype ♀ designated by Deuve (1978: 248) in Muséum National d'Histoire Naturelle, Paris [examined]
Calosoma (Carabomorphus) burtoni Breuning, 1928: 129
Carabomorphus (Carabosophorus) burtoni Lapouge, 1932: 399
Carabops Burtoni Jeannel, 1940: 136

Length 20-27 mm. It is easily recognizable than the other species of the subgenus, if you consider the color of the upper body: head and pronotum black sometimes with weak metallic reflections and elytra reddish. Head and pronotum are also heavily wrinkled, the pronotum moderately transverse, posteriorly narrow, weakly heart-shaped: The elytra are relatively short and enlarged in the posterior third. The sculpture of the elytra has all the 16 intervals of the same width and height (sculpture "homodyname" of Jeannel) and all strongly incised transversely.
It has been found in northwestern Tanzania: the mountainous regions between Lake Tanganyika and Lake Malawi (Mbeya, Njombe and possibly south of the Iringa region).
Breuning (1927:129) reported its capture from the mountain ranges near the lake Bagweulu in northeastern Zambia, but this quote has been deemed incorrect by Basilewsky (1984: 628). Finally Murzin (personal communication) reported a catch in a much further eastern area: Arusha distr., mt.Meru, 1800-2000m,6-7.Apr.1997. J. Stolarezik leg. 1♂ (coll. S. Murzin). However also this finding deserves confirmation.

Examined specimens and literature’s data
Tanzania. Tanganyika Lake (type, MNHN); Nyasa See (MCZR, NMP); Nyassa (RMCA); Mtwara region: Lukuledi (SB, doubtful data); South Iringa region, Ussangu (Breuning, 1928a: 129); Mbeya region Mt.Mbogo, Umalila forêt 2300m (SB; EM).

Notes: Wingless, the wings reduced to an almost invisible stump. Based on the examined capture data, the species is active at the beginning of the rains in December and could remain in activity for the entire rainy period until April.
The species is named after Sir Richard Francis Burton (1821 –1890) the famous British explorer, discoverer of Lake Tanganyika.
