Molorchus sterbai, a rare species endemic to Lebanon, was firstly described as intrasubspecific taxon (aberation) of Molorchus kiesenwetteri by Leo Heyrovský in 1936 [❖]. It was elevated into a species rank under name Molorchus sterbai by Karl Adlbauer in 1988 [✧]. The holotype of the taxon is a specimen of ab. Štěrbai from Heyrovský’s collection, but not a specimen identified by Adlbauer. The taxon was described once more as Glaphyra azri by Gianfranco Sama et al. also from Lebanon in 2010 [☆], so Glaphyra azri Sama, Rapuzzi et Kairouz, 2010, is synonym of M. sterbai [▽].

Molorchus sterbai is a monophagous on the national symbol of Lebanon - Lebanese cedar (Cedrus libani), which belongs among higly endangered and rare conifers of South-East Mediterranean area. Its larvae feed subcortically in dead cedar twigs of small diameters, species' life cycle is 2 or 3 years, adults are active from May to June.
