Hydroporus anatolicus anatolicus J. Balfour-Browne, 1963

Hydroporus anatolicus J. Balfour-Browne, 1963: 2 (original description); Miller and Fery 1995: 408 (description); Nilsson 2001: 159 (catalogue); 2003: 60 (catalogue); Darilmaz and Kiyak 2009: 1614 (catalogue; partim.).

Hydroporus (Sternoporus) anatolicus: Wewalka 1974: 107 (description); Guéorguiev 1981: 407 (catalogue, distribution).

Type locality. “ Turkey: N.E. Anatolia, Zigana ” [pass, ca. 40°37′N 39°21′E, Gümü s ane prov.] GoogleMaps .

Type material. Holotype male ( IRSNB): “ Type [printed, round label with red frame] // Coll.R.I.Sc.N.B. / Turquie, N.E.Anatolie: / Zigana, alt. 2200 m / 16.VIII.1962, E.Janssens [printed] // Hydroporus / anatolicus Type! [handwritten] / J.Balfour-Browne det. [printed] / IV.1963 [handwritten]”.

Additional material examined. TURKEY: six males, five females, Gümü s ane [prov.], Zigana P. [pass], 17 July 1973, G. Wewalka leg. ( GWCW, HFCB, NHMB, NMPC) ; one female, same data, but 30 May 1989, M.A. Jäch leg. ( NHMW) ; one male, 30 km south of Ordu [ca. 40°42′ N, 37°52′ E, Ordu prov.], 12 July 1973, G. Wewalka leg. ( GWCW) GoogleMaps ; one female, Trabzon [prov.], Maçka-Sumela [ca. 40°39′ N, 39°37′ E], 30 May 1989, M.A. Jäch leg. ( NHMW) GoogleMaps .

Measurements. Body length: 3.30–3.45 mm (mean value 3.38 mm), width: 1.50–1.60 mm (mean value 1.57 mm).

Description. Body flat, elongate and subparallel ( Figure 3A View Figure 3 ), sides a little rounded. Elytra distinctly tapering to apex, with maximum width slightly before 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 with paler gula.

Head relatively broad, clypeus broadly rounded. Head with two shallow depressions near anterior margin, and a groove along inner side of each eye. Punctation composed of 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 with maximum width in basal third; sides more or less evenly curved over entire length. Lateral beading distinct, regular. Pronotum with a line of setigerous coarse punctures along anterior margin, and with coarsely punctured shallow posterolateral depressions. Disc of pronotum with sparse and fine setigerous punctures only, their diameter and density similar to those on head. Microreticulation similar to that of head, but slightly less impressed.

Elytra with sides almost straight in anterior third, widest before midlength, then distinctly 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 slightly larger than their diameter. Epipleura very large basally, regularly attenuating down to anterior third, then evenly thin to apex.

Legs: protibiae and mesotibiae distinctly triangular, narrow basally and regularly broadened to apex.

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 strongly hooked. Median lobe of aedeagus in ventral view ( Figure 2A View Figure 2 ) with long, very thin apex; strongly inflexed in middle, with long and nearly straight apex in lateral view. Paramere as in Figure 2B View Figure 2 .

Female: microreticulation of elytra more distinct than in males, hence surface subopaque. Claws of fore legs thin, only slightly curved.

Distribution. North-eastern Turkey (Ordu, Gümü s ane and Trabzon provinces) ( Figure 6 View Figure 6 ).
