Neomarius gandolphii, an interesting and not often collected Magrhebian member of Oemini tribe known from Algeria and Morocco, has been described from Algeria by Léon Fairmaire in 1872 [❖][✳]. N. gandolphii develop in sick, dying or freshly dead coniferous trees (Abies, Cedrus). Larvae feed subcortically, in late summer penetrate the sapwood and create hook-shaped pupal cell in the wood [✧][✮]. Adults, active from March to June, are crepuscular/nocturnal and can be attracted by light.

Body length:	10 - 24 mm
Life cycle:	1 year [?]
Adults in:	March - June
Host plant:	oligophagous in conifers (e.g. Abies numidica, Cedrus atlantica)
Distribution:	Algeria, Morocco

The depicted specimen was reared from larva collected in dead Algerian fir (Abies numidica) in Djebel Babor (ولاية سطيف) mountain range (1900 m a.s.l, Sétif province, Algeria) on June 1, 1996.
