Calosoma (Orinodromus) glaciale Kolbe, 1905

Orinodromus gerstaekeri subsp. glacialis Kolbe, 1905: 593 note 62 (type locality: Kilima-Ndjaro, 4.000 m.); type material and repository originally not stated, in Museum für Naturkunde Humboldt Universität, Berlin (Jeannel, 1940: 149)
Calosoma (Carabomorphus) deckeni subsp. glaciale Breuning, 1928: 137
Carabomorphus (Orinodromus) deckeni glacialis Lapouge, 1932: 398
Orinodromus glacialis Jeannel, 1940: 149

Length 15-18 mm. Three species, divided by altitudinal belts and exposure of the slopes, are found on Mount Kilimanjaro: C. deckeni, C. glaciale and C. volkensi. All have the rear lobes of pronotum, small but well developed, and provided with one bristle. Jeannel (1940) distinguished these species, placing them, together with C. neumanni, another species of Tanzania, in the subgenus Orinodromus s. str.
As it is the case with the other high altitude species of Mount Kilimanjaro C. glaciale is very small, but it can be easily distinguished because of the pronotum somewhat narrower at the base. Furthermore, the upper body is entirely black, the elytra are smooth without visible sculpture, and the penis has the ligule with a normal, not bifurcate, apex.
It has been found on Kilimanjaro, but only at the base of the glacier, southwest of the cone of Kibo (around 4,000 m.).

Examined specimens and literature’s data
Tanzania. Kilimanjaro, 4000 m (RMCA, SB), Kibo glacier 4000m., above Kibosho 4000m. (Basilewsky, 1962: 68)

Notes: Wingless. It has been found under stones, on alpine meadows characterized by the presence of Helichrysum, Hercinella and Senecio johonstoni. Catches are reported in February just before the long rains (Alluaud, 1917: 81).
