Arhopalus pinetorum, a species endemic to Canary Islands developing in dead pines, has been described from La Palma island (reared from larva found in dead pine in pine forests between the plains of Los Llanos and the Great Caldeira) as Criocephalus pinetorum by Thomas Vernon Wollaston in 1863 [❖]. The A. pinetorum biology is similar to other species of the genus. The larvae develop in highly moist and decaying wood of dead pines. Adults, active from June to August, are crepuscular and nocturnal [✮].

Body length:7 - 28 mm
Life cycle:several years
Adults in:July - August
Host plant:pines (Pinus radiata - syn. Pinus insignis, Pinus canariensis)
Distribution:species endemic to Canary Islands (El Hierro, La Palma, La Gomera, Tenerife)

The depicted mounted beetles were reared from larvae found in trunk of dead Pinus canariensis in Bosquede la Esperanza environs (1685 m a.s.l., NE Tenerife, Canary Islands, Spain) on June 26, 2019 together with larvae of allied species Cephalocrius syriacus (Reitter, 1895).
