Male—Integument smooth (possibly due to the molecular analysis treatment) but occasionally fine striation is visible. Posteromedial margin of Cx-I triangular (Figure 1A), Cx-IV medial margin nose-like protruding. Anterior margin of genital plate with a small, knob-shaped medial projection, posterior margin indented (Figure 1B); acetabula arranged in an obtuse triangle: excretory pore unsclerotized.</p><p>Palp as illustrated in Figure 1C; P-2 ventral margin straight, distally forming a right angle, denticles covering two-thirds of the ventral margin of both P-2 and P-3; P-4 ventral setae on the same level.</p><p>Measurements— Idiosoma L 1260, W 1175. Coxal shield L 569; Cx-III W 700; Cx-I+II L 469, Cx-I+II lL 450. Genital field L/W 281/331, ratio 0.85, L Ac-1-3: 94, 122-125, 105.

Chelicera L 433, basal segment L 291, claw L 150. dL of I-L-2–6: 138, 198, 275, 284, 259; dL of IV-L: 184, 203, 291, 425, 426, 353.</p><p>Female—Unknown.</p><p>Etymology —The species is named for Prof. Dr. Davut Turan (Recep Tayyip Erdogan University, Rize, Türkiye) for his great contribution to the knowledge of the ichthyofauna of Türkiye.</p><p>Species delimitation using DNA-barcodes — The final alignment for species delimitation using COI sequence data comprised 658 nucleotide positions (nps) from 30 Hygrobates specimens listed in Table 2 and one outgroup, Atractides nodipalpis from the Netherlands. The NJ tree is presented in Figure 2. The COI tree sequence retrieved from a specimen of H. turani sp. nov. from Türkiye appeared as a sister taxon of H. anatolicus Esen &amp; Pešić, 2013 . The mean genetic distance between COI sequences of these two species was estimated at 16.1% K 2P. Only one specimen of the new species could be acquired for use in molecular analyses, so intraspecific differences in COI sequence could not be examined.</p><p>Discussion — Based on COI data, the new species from northeastern Türkiye appears to be most closely related to Hygrobates anatolicus, a species known from eastern Türkiye (Esen et al. 2013). Males of H. anatolicus can be distinguished from the new species by having a lineated integument (occasionally forming irregular ridges), a less projecting posteromedial margin of Cx-I, and larger genital acetabula (Esen et al. 2013).</p><p>Distribution — Türkiye; known only from the type locality (Figure 6A).</p></div>	https://treatment.plazi.org/id/670187899F2BD838FF2BFAE4FC00F92B	Public Domain	No known copyright restrictions apply.

The COI tree sequence retrieved from specimens here described as Atractides karadenizensis sp. nov. from Türkiye appeared as a sister taxon of A. gibberipalpis Piersig, 1898 .

This rhithrobiontic species, considered widely distributed across the Palaearctic region (e.g., Gerecke et al. 2016; Pesic &amp; Erman 2006), can be distinguished from the new species by the shape of the male genital plate, in which Ac-3 is strongly elongated and drop-shaped (Gerecke 2003; Pešić &amp; Smit 2021). The high genetic distance between the new species and A. gibberipalpis (COI 17.3% K2P) suggests a long independent evolutionary history for the new species. Atractides yazdensis Pešić, Smit &amp; Saboori, 2021, a species originally described from south Iran differs from the new species in I-L with enlarged penultimate segment bearing a truncated sword seta S-1 and P-4 sword seta slightly proximal to posteroventral hair (see Pešić et al. 2021b).</p><p>Distribution — Türkiye; known from Rize province (Figure 6B).</p></div>	https://treatment.plazi.org/id/670187899F2DD831FF2BF901FC75FE58	Public Domain	No known copyright restrictions apply.

The examined specimen from Trabzon used in this study for molecular analysis matches the description of Sperchon milisai, a species previously known only from the Western Balkans (Pešić et al. 2025c).

The p - distance between these two BINs was estimated at 4.65%.As emphasized by Pešić (2022), it is likely that, due to the unsclerotized excretory pore, females of S. milisai were previously confused with S. clupeifer, a species frequently reported from streams in Europe and Türkiye (Erman et al. 2010; Pešić et al. 2025c). Males of S. clupeifer, however, can be readily distinguished by their dorsal shield, more slender palps (P-4 L/H ratio&gt;5.5), and differently shaped ejaculatory complex (see Pešić 2022).</p><p>Distribution: Western Balkan (Montenegro, Croatia, Albania, Bosnia and Herzegovina; Pešić et al. 2025c).
