Body length: 3.15–3.50 mm (mean value 3.36 mm ), width: 1.45–1.60 mm (mean value 1.54 mm ). Description. Body flat, elongate, rather parallel sided ( Figure 3E ), sides a little rounded. Elytra only weakly tapering to apex, with maximum width near midlength. Pronoto-elytral angle quite distinct. Upper surface blackish-brown, sides of pronotum and head often paler. Mouth appendages and legs testaceous. Ventral part blackish, head with paler gula. Head relatively broad, clypeus broadly rounded. Head on surface with two shallow depressions near anterior margin, and a groove along inner side of each eye. Punctation comprising sparse, almost regularly distributed punctures (denser in depressions), slightly smaller on clypeus and bigger on frons and vertex. Distance between punctures about twice their diameter. Microreticulation consisting of polygonal meshes with diameter smaller than that of punctures. Pronotum of rather variable shape. Usually with maximum width near midlength, sides more or less evenly curved over entire length; but in some specimens sides rather subparallel in posterior half. Lateral beading distinct, regular. Pronotum with a line of coarse setigerous punctures along anterior margin, and with shallow coarsely punctured posterolateral depressions. Disc of pronotum with sparse and fine setigerous punctures similar to those on head, but their diameter slightly smaller, and distance between punctures nearly three times their diameter. Microreticulation similar to that of head, but slightly less impressed. Elytra with sides almost straight behind shoulders, widest near midlength, then weakly tapering to apex; marginal rim visible at shoulders in dorsal view. Elytral disc with two rather indistinct punctured lines and with quite regularly distributed moderately large setigerous punctures between these lines. Distance between punctures about twice the diameter. Ventral part microreticulated. Reticulation indistinct on meso- and metaventrite, but stronger on metacoxal plates and abdominal ventrites. Metaventrite, metacoxal plates and two basal abdominal ventrites with large setigerous punctures. Other abdominal ventrites with sparse fine punctures. Male: dorsal surface shiny. Claws of fore tarsi broadened, strongly hooked. Median lobe of aedeagus regularly tapering to apex in ventral view, apical part relatively short, slightly turned to right ( Figure 2E ). In lateral view, median lobe strongly inflexed in middle, apex long and nearly straight. Paramere as in Figure 2F . Female: pronotum slightly broader than in male. Microreticulation of elytra more distinct than in males and surface subopaque. Claws of fore legs thin, only slightly curved. Remarks. The type locality of Hydroporus bodemeyeri was stated as “In Mehrzahl bei Karakeuy gesammelt.” [Most specimens collected at Karakeuy (= Karaköy village).] (Ganglbauer in Bodemeyer 1900: 140 ). According to the Microsoft Encarta World Atlas 2000 , there are about 50 different villages named “Karaköy” in Turkey . Miller and Fery (1995: 410) assumed the type locality to be the village lying ca. 80 km north of Adana and 60 km east of Bulghar Dagh [= Bolkar Daglari Mountains]. We believe that the assumption is erroneous for two reasons. First, Bodemeyer (1900: 98) used the following abbreviation for the locality: “Ka. = Karakeuy, Station der anatolischen Bahn.” [station of the Anatolian railway]. There is no railway around the place cited by Miller and Fery (1995: 410) . Second, Bodemeyer (1900: 24) presented precise information about Karaköy within the chapter “Reise von Konstantinopel nach Konia längs der anatolischen Bahn” [Travel from Constantinople (= Istanbul ) to Konya along the Anatolian railway], and placed Karaköy between Bilecik and Eski s ehir “...Steigt die Bahn von Biledjik aus schon steil zur Hochebene hinan, so hat man in Karakeuy 620 Meter, in Eski- Chéhir schon 800 Meter erreicht...” [...the railway runs up steeply from Bilecik to the plateau, and therefore it reaches 620 meters in Karaköy, and 800 meters already in Eski s ehir...]. Therefore we assume that the type locality of H. bodemeyeri is the Karaköy village in Bilecik Province , ca. 22 km south of Bilecik , geographic co-ordinates 39°57′ N , 29°59′ E . Distribution. The occurrence of the nominotypical subspecies is here confined to Greek Islands (Ikaría, Khios, Lésvos, Samos) and to the western half of Asian Turkey ( Adana , Ankara , Antalya , Bolu , I zmir and Nev s ehir provinces) ( Figure 6 ).
