Diagnosis: key to the species of Dichorrhinus Desbrochers, 1875 View in CoL
1. Elytra with shorter and adherent hairs. Scales on elytra elongate drop-shaped, green or brown to copper metallic, femora unarmed. Libya (Type locality: Cirene) .......................... freyi F. Solari, 1940 View in CoL
– Elytra with longer and semi-raised hairs. Scales on elytra more circular, green to greenish-bluish metallic.................................................................................................................................................2
2. Head stout, rostrum very short. Eyes smaller, antennae and legs reddish brown and short, femora unarmed ( Fig. 1E, J View Fig ). Aedeagus short, conical, obtuse-angled and pointed at tip ( Fig. 2R, S View Fig ). Syria, Lebanon (Type locality: Djebel Baalbeck) .................................. pseudoscythropus Desbrochers, 1875 View in CoL
– Rostrum longer. Eyes bigger and/or more bulged. Antennae and legs longer, at least femora darkened, and mostly at least metafemora toothed (remark: no teeth were found on femora of D. alziari View in CoL sp. nov.; in D. geiseri View in CoL sp. nov. there were always teeth varying from small and sharp to well pronounced and strong; in D. creticus View in CoL and D. korbi View in CoL there were all transitions from untoothed to small and sharp, toothed to strongly toothed)......................................................................................3
3. Antennae reddish brown, eyes big, semi-circular, protruding ( Fig. 1B, G View Fig ). Apex of aedeagus with very long spine ( Fig. 2P, Q View Fig ). Greece: Crete Island (= type locality) ......................... creticus (Faust, 1889) View in CoL
– Antennae darkened, eyes otherwise, aedeagus different.......................................................................4
4. Eyes big, less than semi-circular, protruding, head as Fig. 1H View Fig . Aedeagus laterally constricted before apex. Apex with short and rounded (blunt) spine ( Fig. 2 View Fig A-F). Western Turkey, Greece: Samos Island (= type locality) .................................................................................... geiseri View in CoL sp. nov.
– Eyes smaller and strongly protruding (almost or distinctly semi-circular). Tip of aedeagus different ( Fig. 2 View Fig G-O)...........................................................................................................................................5
5. Eyes protruding, distinctly semi-circular, slightly asymmetrically curved ( Fig. 1D, I View Fig ). Aedeagus broader, laterally slightly rounded, apex acute-angled and pointed ( Fig. 2 View Fig K-O). Turkey (Type locality: Amasia) .................................................................................................. korbi Schilsky, 1911 View in CoL
– Eyes protruding, less than semi-circular, symmetrically curved ( Fig. 1A, F View Fig ). Aedeagus slender, parallel-sided to concave, apex obtuse-angled and pointed ( Fig. 2 View Fig G-J). Cyprus (Type locality: Troodos Mts) ................................................................................................................... alziari View in CoL sp. nov.
Further records
The seasonally early-appearing species of Dichorrhinus are rarely collected and published data is scarce. Therefore, I add the following records, registered during examinations for the present study:
