The subfamilies Alticinae and Cryptocephalinae were the best represented, in accord with the habitate conditions. A serie of 13 species here rgistered are rare and endangered species, other species found only in that area the characteristical vegetal food species. Rezumat Cercetări asupra crizomelidelor (Coleoptera: Chrysomelidae) în habitatul pinului negru de Ba- nat şi ariile adiacente din cadrul Parcului Naţional “Domogled-Valea Cernei” În urma unei investigaţii facute în 2005 în zona studiată, am identificat 55 de specii de cri- zomelide din 22 de genuri şi 8 subfamilii. Subfamiliile Alticinae şi Cryptocephalinae au fost cel mai bine reprezentate, in acord cu condiţiile de habitat oferite de această arie. Un număr de 13 specii dintre cele identificate sunt considerate rare şi periclitate; alte specii găsesc doar in această zonă baza tzrofică caracteristică.
