Macrotoma palmata, predominantly an element of the Ethiopian zoogeographic region (in West Palearctics distributed in Algeria, Morocco, Egypt, Libya, Saudi Arabia and Yemen), has been described from Guinea as Prionus palmatus by Johann Christian Fabricius in 1793 [✧]. This impressive species is polyphagous on many deciduous trees, but in North Africa chiefly on Vachellia (former Acacia) such as V. nilotica, V. tortilis raddiana, and V. seyal (in Libya only observed on V. tortilis raddiana) [❖].

Body length:25 - 60 mm
Life cycle:several years
Adults in:May - October
Host plant:Vachellia tortilis, Vachellia nilotica
Distribution:WP: Algeria, Morocco, Egypt, Libya, Saudi Arabia and Yemen

The mounted beetles were reared from larvae found in dead Vachellia tortilis in M'Ssici village environs (N31°13′12″ W04°47′42″; 812 m a.s.l., Jebel Tiskaouine, Drâa-Tafilalet region, Morocco) on May 20, 2023 (the last instar larvae finished maturation in dead oak wook). Depicted living adults of Macrotoma palmata were collected on their host Vachellia tortilis raddiana near Germa, Fezzan (Libya).
