Taxonomic position and diagnostic characters: Easily diagnosed from its closest allies from Turkey, Lebanon and Iran ( H. caucasica complex; Table 1) by the wide and laterally rounded pronotum ( Fig. 16a View FIGURES 16 ), and the strongly differently shaped aedeagus, characterized (in lateral view) by a bifurcate and sickle-shaped apical half of main piece ( Fig. 16c View FIGURES 16 ).

Hydraena (Haenydra) septemlacuum Jäch 1992: 84 View in CoL ;

Male habitus: Fig. 16b View FIGURES 16 ; male genitalia: Fig. 16d View FIGURES 16 ; female elytral apex: Fig. 16m View FIGURES 16 ; geographic range: Fig. 17 View FIGURE 17 .

Type locality: Turkey, Bolu province, Yedigöller National Park (“ Stream in Yedigöller National Park , Bolu Province, northwestern Turkey ”: Jäch 1992) .

Primary types: Holotype at NMW.

Measurements: Length: 2.3 – 2.5 mm. EL/EW = 1.71; PW/PL = 1.50; PW/EW = 0.82.

Diagnosis: Body reddish brown to dark brown. Palps and legs pale reddish brown. Labrum with V-shaped notch on anterior margin. Fronto-clypeal suture slightly arcuate, not strongly impressed, frons relatively densely punctate, especially in lateral portion. Pronotum sub-hexagonal, with lateral margin denticulate. Pronotal disc relatively convex, rather densely punctate near anterior and posterior margin. Elytra notably elongate, completely parallel-sided, notably explanate in lateral margin. Elytral apex slightly conjointly rounded in male, distinctly conjointly rounded, and with a small V-shaped sutural notch, in female ( Figs. 16b,m View FIGURES 16 ). Male meso- and metatibiae with a more or less prominent dilatation in the inner edge of distal third. Male metatibiae with fringe of long setae along mesal face of distal half ( Fig. 16b View FIGURES 16 ).

Taxonomic position and diagnostic characters: Easily diagnosed from its Turkish allies H. plastica , H. caucasica , H. khnzoriani , and H. nilguenae by the peculiar parallel-sided and markedly elongate elytra, and the shape of male genitalia ( Figs. 16b,d,m View FIGURES 16 ). Moreover H. septemlacuum can be distinguished from H. plastica and H. khnzoriani by the straighter apical half of the aedeagal main piece. Female of H. septemlacuum can be distinguished from female of H. crepidoptera by the more prominent elytral sutural notch in the latter species ( Fig. 16m View FIGURES 16 ). Finally, H. septemlacuum is barely distinct from its sibling H. sinope by the differently shaped apex of the aedeagal main piece ( Fig. 16d View FIGURES 16 ). [See also taxonomic notes about the following species].

Habitat: This species was collected in two sites (200 and 950 m a.s.l.) under stones in cold fastflowing streams, with carbonatic substrates, in mixed forest.

Chorotype: ANAN (N Anatolian = Pontic Endemic).

Distribution: AS: TR ( Fig. 17 View FIGURE 17 ).

Up to now, H. septemlacuum was considered to be endemic to the Yedigöller National Park (NW of Turkish Pontic chain), but recently ( Ribera et al. 2011) a specimen belonging to this species was collected in Bartin province (CN of Pontic chain), within the geographic range of its sibling, and so far considered allopatric species, H. sinope (see also Taxonomic Remarks of the following species, and Appendix 2 for all the detailed known localities).

DNA data: For this species, mtDNA data (COI, 16S rDNA, tRNA leu and NAD1) are available in GenBank ( Ribera et al. 2011; Trizzino et al. 2011b).

Male genitalia: Fig. 16e View FIGURES 16 ; female elytral apex: Fig. 16n View FIGURES 16 ; geographic range: Fig. 17 View FIGURE 17 .

Type locality: Turkey, Ordu province, Gölköy (“ TR- ORDU 28.5. s. Gölköy ”: Jäch 1992) .

Primary types: Holotype at NMW.

Measurements: Length: 2.3 – 2.5 mm. EL/EW = 1.71; PW/PL = 1.50; PW/EW = 0.82

Diagnosis: Male habitus identical to H. septemlacuum ( Fig. 16b View FIGURES 16 ).

Taxonomic position and diagnostic characters: See differential diagnosis of H. septemlacuum .

Habitat: This species was collected under stones in cold fastflowing streams with carbonatic substrates above 900 m a.s.l.

Chorotype: ANAN (N Anatolian = Pontic Endemic).

Distribution: AS: TR ( Fig. 17 View FIGURE 17 ).

H. sinope is known from a few localities in N Turkey (see Appendix 2 for all the detailed known localities).

Taxonomic remarks: Recent molecular analyses ( Trizzino et al. 2011b; Ribera et al. 2011) evidenced that a specimen of H. septemlacuum from Bartin province (N Turkey) was more related to H. sinope (from the same region) than to a specimen from type locality (Bolu province) of the same species. H. sinope was firstly described by Jäch (1992) as a subspecies of H. septemlacuum (described in the same paper) and afterwards elevated to specific rank by the Jäch & Díaz (2001), mainly based on the slightly differently shaped apex of aedeagal main piece and on the basis of the allopatric distribution. Deeper studies are required, but recent faunistic and molecular data suggested that these two taxa are probably synonyms.

DNA data: For this species, mtDNA data (COI, 16S rDNA, tRNA leu and NAD1) are available in GenBank

( Ribera et al. 2011; Trizzino et al. 2011b).
