Ecology and presence in Slovenia
The species is distributed in central and southern Europe, the Caucasus, Crimea, North Africa and Asia Minor. Siegel (1866) states that the species was “rare in Carniola, under pine bark”. In Slovenia, only two recent records are known from the Slovene part of Istria (Figure 62). Hosts: polyphagous on Pinus spp. (P. sylvestris, P. nigra, P. pinaster, P. mugo), mainly on continental species. In Slovenia it has been found only on P. nigra. C. minimus develops as a secondary species on thinner branches of dying pines, often in partially dry bark. It excavates a 5-6 cm long longitudinal star-shaped tunnel system, the two upper and two lower maternal galleries forming an X. Adult length is 1.2-1.7 mm. Occurs together with Pityogenes spp. and Ips acuminatus, its tunnel system is smaller and more deeply embedded in sapwood.
