Hydroporus toledoi sp. n.

( Figs 4 , 13 )

Type locality. Turkey, Rize province, SE Çamlihemsin, ca. 40.94N 41.24E, altitude 1600–1650 m (locality 6 in Fig. 13 ).

Holotype. 3, " Turkey –Rize, Çamlihemsin, 12.VIII.1992, l. Toledo. M.", "Small streams on road Ayder–Libler Gölü, m 1600–1650", " Holotype, Hydroporus toledoi sp. n., H. Fery & Ö.K. Erman det. 2009" [red, printed] ( NMW). Paratypes. 1 Ƥ, same label data as the holotype, but a red paratype label (CMT).

Notes. The Libler Gölü [= Lake Libler] is situated in the Kaçkar mountain range at an altitude of 2753 m, SE Çamlıhemşin, ca. 40.94N 41.24E, E Ayder (or Ayder Kablıca), ca. 40.95N 41.11E.

Differential diagnosis. Upper side only brownish on vertex of head, anterior margin of pronotum, and posterior part of pronotal beading, rest black. Surface with reticulation more impressed, and thus with a duller appearance, than in H. cargrankaya sp. n. Ventral side, gula and genae black; prosternal process dark brownish. Femora only slightly darkened. Antennomeres not darkened distally, except weakly darkened eleventh. Legs and antennae lighter brownish, as in H. cagrankaya sp. n.; contrast to black surface more distinct.

Males. Median lobe of aedeagus in ventral view strongly converging apically, apex very shortly rounded ( Fig. 4 ); apex with tip rather pointed in lateral view.

Females. See remarks under H. cagrankaya sp. n.

Measurements. TL: 3.3–3.4 mm, MW: 1.55–1.6 mm; TL/MW: 2.13: IO/MP: 0.46–0.48.

Distribution. So far known only from the locus typicus near Çamlihemsin in the Rize province, northeastern Turkey (locality 6 in Fig. 13 ).

Derivatio nominis. The species is named after our colleague and friend M. Toledo (Parma, Italy) who kindly has submitted his material (noun in the genitive case).
