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 mounted 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 1998. This record represented the first evidence of this introduced species' presence in continental Greece.
