Xylotrechus stebbingi, a species of Oriental origin widespreading in Western Palaearctic during the last 30 years [✧], has been described from Himalaya by Charles Joseph Gahan in 1906 [▽]. According to Francesco Vitali this introduced species was for a long time errorneously identified and corresponds to a taxon Xylotrechus smei (Laporte de Castelnau & Gory, 1841) [❖]. Gianfranco Sama refuted this theory in his 2006 paper [★] (to illustrate, we present photographs of type specimens of both discussed taxa provided by Pierpaolo Rapuzzi).

Body length:12 - 23 mm
Life cycle:2 years
Adults in:May - July
Host plant:polyphagous in deciduous trees
Distribution:introduced to Albania, Crete, Cyprus, France, Germany, Greece, Italy, Spain, Switzerland, Israel, Liban, Slovenia, Syria, Tajikistan, Tunisia, Turkey

The depicted beetles were reared from larvae found in a dead large diameter branch of Ficus carica. The branch was collected in Neo Ithilo (Lakoonia nomos, SW of Peloponnese, Greece) in May 2022.
