The holotype is stored in the NMW. The habitus of this species is given in Fig. 16, the male genitalia in Figs 29 and 33; see Figs 15, 28 and 32 for <i>R. agnus</i>.</p> <p> So far this taxon was treated as a subspecies of <i>R. agnus</i>. Because the type localities of the two subspecies are only about 10 km away from each other, the authors of the original description hesitated to assign specific rank to <i>R. argaensis</i>. On the other hand, they found that the two taxa are obviously incapable of dispersal by flight (BILTON & FERY 1996: 924). This is why the authors suspected that both subspecies might be given specific rank following (future) genetic investigations and wrote "... but it would appear that these represent taxa on their way to speciation." (BILTON & FERY 1996: 928).</p> <p> Recently, such genetic investigations have been presented by ABELLÁN et al. (2013, appendices) and Ignacio Ribera (Barcelona, Spain) communicated privately that if both subspecies have "... enough morphological differences they can be upgraded to species... genetically they are very close, but well separated." In particular, the differences in the male genitalia are very distinct (see Figs 28 and 29), and thus the rank of <i>argaensis</i> is here elevated from subspecific to specific.</p> <p>The data of the specimens used for the genetic studies in ABELLÁN et al.

Clemnius Fery 2017, n. gen.
Genus Clemnius n. gen. Type species: Hyphydrus decoratus Gyllenhal, 1810: XVI, by present designation. The new genus Clemnius n. gen. includes eight described species distributed in the Nearctic (including the north of MeXico, sometimes treated as Neotropical) and in the Palaearctic zoogeographical region (Fig. 2 and Table 1). Diagnosis. In the new classification Clemnius n. gen. is one of two genera of the tribe Hygrotini. All species of this and the second genus Hygrotus have two carinae in each antennal cavity (see Figs 4–6), a unique character among the entire subfamily Hydroporinae. The new genus—which corresponds to clade A in Fig. 1 —is a heterogeneous assembly of relatively small species with different morphological characters. It is subdivided into two sister-clades each treated as a subgenus: Cyclopius n. subgen. and Clemnius s. str. n. subgen. (see Fig. 2).Published as part of Fery, Hans, 2017, A new classification of the tribe Hygrotini Portevin, 1929 (Coleoptera: Dytiscidae: Hydroporinae), pp. 499-529 in Zootaxa 4317 (3) on page 503, DOI: 10.11646/zootaxa.4317.3.4, http://zenodo.org/record/88476
Hydroporus artvinensis Fery & Erman, 2009, sp. n.
Hydroporus artvinensis sp. n. (Figs 3, 13) Type locality. Turkey, Artvin province, Şavşat, Karagöl, ca. 41.24 N 42.37 E (locality 7 in Fig. 13). Holotype. 3, " TR –Artvin, Şavşat, Karagöl, 17.9. 2001, Leg. Ö. Köksal Erman"; " Holotype, Hydroporus artvinensis sp. n., H. Fery & Ö.K. Erman det. 2009 " [red, printed] (NMW). Paratype. 1 Ƥ, same label data as the holotype, but a red paratype label (CHF). Differential diagnosis. Very similar to H. cagrankaya sp. n., but upper side black except on vertex of head. Punctation of elytra slightly coarser. Ventral side with gula and genae black; prosternal process blackish. Legs uniformly rather dark brownish, thus darkening of femora indistinct. Antennal segments also uniformly darker, apical darkening indistinct. Contrast of brownish legs and antenna to rest of surface decidedly weaker than in H. toledoi sp. n. Males. Median lobe of aedeagus in ventral view weakly tapering to apex, tip broadly rounded (Fig. 3). Females. See remarks under H. cagrankaya sp. n. Measurements. TL: male holotype: 3.3 mm, MW: 1.65 mm, TL/MW: 2.0; female paratype: TL: 3.4 mm, MW: 1.75 mm; TL/MW: 1.94, IO/MP: 0.46. Distribution. So far known only from the locus typicus Karagöl near Şavşat in the Artvin province, north-eastern Turkey (locality 7 in Fig. 13). Derivatio nominis. The species is named after the Artvin province in north-eastern Turkey, where the new species has been found.Published as part of Fery, Hans & Erman, Ömer Köksal, 2009, Five new species of the longulus - group of Hydroporus Clairville, 1806 from north-eastern Turkey (Coleoptera: Dytiscidae), pp. 1-12 in Zootaxa 2033 on page 9, DOI: 10.5281/zenodo.18632
Nectomimus Fery & Ribera 2018, n. gen.
Genus Nectomimus n. gen. (1 species) (PL) Type species: Oreodytes okulovi Lafer, 1988: 52 by present designation (habitus in Fig. 26.12). Nectomimus n. gen. cοntains οnly a single species, N. okulovi, which sο far was included in the genus Oreodytes (fοrmer sense). We cοuld οbtain sοme incοmplete mοlecular data οf a badly preserved specimen οf N. okulovi (Appendix 3), which was nοt sufficient tο resοlve unambiguοusly the phylοgenetic pοsitiοn οf the species, althοugh it seems tο be related tο the clade Hornectes n. gen. plus Nectoporus (Figs 28–31). Description: Bοdy shape οval (TL/MW: 1.62–1.68); small species (TL: 2.95–3.2 mm, MW: 1.8–1.95 mm). The fοllοwing cοmbinatiοn οf character states separates the species and with this the new genus frοm οther genera οf Derοnectina (in particular frοm Nectoporus and οther genera fοrmerly included in Oreodytes): (1) bοdy οutline in dοrsal view mοre οr less cοntinuοus, with οnly weak discοntinuity at base οf prοnοtum (Fig. 26.12); (2) οutline behind shοulders straight, diverging pοsteriad, rοunded οnly behind mid-length οf elytra; (3) ventral surface matt [31(1)]; (4) prοsternal prοcess elοngate [27(0)], sοmewhat brοad, but neither triangular nοr rectangular; (5) venter withοut platfοrm [39(0)]; (6) interlaminary bridge expοsed (similar tο Fig. 16.2) [33(1)]; (7) male prο- and mesοtarsοmeres withοut sucker cups [48(0)]. The species shοws alsο the fοllοwing οther features: (8) elytra vittate (Fig. 26.12) [6(1)]; (9) epipleura nοt cοnstricted at level οf first abdοminal ventrite, mοre οr less evenly tapering tο elytral apex (similar tο Figs 6.3, 17.3) [20(1)]; (10) in lateral view epipleura visible until shοulders (similar tο Fig. 5.6) [18(1)]; (11) mοst parts οf metaventrite and metacοxal plates cοvered with very small and densely arranged punctures, withοut large punctures [40(0)]; (12) venter nοt reticulate, althοugh sοmetimes—depending οn angle οf οbservatiοn—appearing as reticulate and (13) densely arranged small punctures οften cοntacting and fοrming wοrm-like structures; (14) metacοxal lines very weakly divergent anteriad; (15) distal part οf median lοbe οf aedeagus lοng and narrοw, in strοng cοntrast tο species οf Nectoporus (see figs. 3, 4 and 6, 7 in Fery & Petrοv 2014); (16) parameres mοre οr less triangular, lacking apical hοοk and lamella (Fig. 23.3) [53(0)]. Notes: With its vittate elytra and small size, Nectomimus okulovi appears at first glance as belοnging tο the shοrt members οf fοrmer genus Oreodytes (nοw Nectoporus). It is, hοwever, different frοm the "shοrt" fοrmer Oreodytes (and all οther fοrmer Oreodytes) because the males lack the sucker cups οn prο- and mesοtarsοmeres, by the shape οf the prοsternal prοcess, the shape οf the epipleura which are visible until shοulders in lateral view, the shape οf the aedeagus and the tοtally deviating surface structure οf the ventral surface. In οne male and οne female οf N. okulovi we have fοund cοnsiderably reduced hind wings. Fοr a mοre detailed descriptiοn see Fery & Petrοv (2014). Etymology: The name οf the new genus relates tο Nectoporus and the Greek µίµος (mimοs = imitatοr). The gender οf the name is masculine. Distribution: Palaearctic: Russia (Eastern Siberia, Far East). Habitat: The species seems tο οccur in rivers and brοοks (Fery & Petrοv 2014).Published as part of Fery, Hans & Ribera, Ignacio, 2018, Phylogeny and taxonomic revision of Deronectina Galewski, 1994 (Coleoptera: Dytiscidae: Hydroporinae: Hydroporini), pp. 1-104 in Zootaxa 4474 (1) on pages 34-35, DOI: 10.11646/zootaxa.4474.1.1, http://zenodo.org/record/145268

Hydroporus puberulus Fery & Hendrich, 2011, sp. n.
The Hydroporus puberulus -group The new species belongs to the Hydroporus puberulus -group. According to Nilsson & Holmen (1995: 40 ff, 61) this "poorly delimited" group contains both Nearctic and Palaearctic species and is characterised by the following features: (1) elytra on disc with impressed reticulation; (2) pronotum with lateral beading more or less reduced; (3) lateral margin of elytra distinctly ascending to humeral angle; (4) lateral outline of body with a slight discontinuity at level of pronotal base; (5) metacoxal processes with posterior margin conjointly truncate; (6) base of prosternal process not prolonged anteriorly as a distinct convexity; (7) third protarsomere not unusually prolonged. Including the new species, the members of the puberulus -group are (cf. Nilsson 2001): - Hydroporus esseri sp. n. (Palearctic) - Hydroporus glabriusculus Aubé, 1838 (Palearctic) - Hydroporus morio Aubé, 1838 (Holarctic) (given as member of the Hydroporus nigellus -group in Nilsson & Holmen 1995) - Hydroporus puberulus LeConte, 1850 (Holarctic) - Hydroporus rufinasus Mannerheim, 1852 (Nearctic) - Hydroporus umbrosus (Gyllenhal, 1808) (Palearctic)Published as part of Fery, Hans & Hendrich, Lars, 2011, Hydroporus esseri sp. n., a new diving beetle from southern Turkey (Coleoptera, Dytiscidae, Hydroporinae), pp. 38-46 in Zootaxa 2909 on page 39, DOI: 10.5281/zenodo.20511
Hydroporus sivrikaya Fery & Erman, 2009, sp. n.
Hydroporus sivrikaya sp. n. (Figs 2, 13) Type locality. Turkey, Rize province, İkizdere district, ca. 8–9 km SE Sivrikaya village, ca. 40.63 N 40.79 E, altitude ca. 2600 m (locality 5 in Fig. 13). Holotype. 3, " 29.06.2001 TR –Rize prov., İkizdere distr., 8–9 km SE Sivrikaya village, ca. 2600 m ", "spring on left side of road İkizdere–Erzurum, Erman, Ö.K. leg.", " Holotype, Hydroporus sivrikaya sp. n., H. Fery & Ö.K. Erman det. 2009 " [red, printed] (NMW). Paratypes. 5 33, 1 Ƥ, same label data as the holotype. Each paratype is provided with the respective red label (CHF, CKE). Differential diagnosis. Pronotal rim in most specimens entirely black, only one specimen with short dark brownish posterior spot. Sides of pronotum less curved, almost straight, but diverging in posterior half, thus, discontinuity between pronotum and elytra still less perceptible than in H. cagrankaya sp. n. Punctation on elytra slightly coarser and denser. Ventral side with gula and genae black; prosternal process almost entirely blackish. Femora, as well as pro- and mesocoxae, distinctly darkened; trochanter, tibiae and tarsi brownish. Antennal segments—except eleventh—not darkened distally, or only very indistinctly so. Males. Median lobe of aedeagus in ventral view less converging apically, apex very broadly rounded, almost truncate (Fig. 2); in lateral view with tip slightly less pointed. Females. See remarks under H. cagrankaya sp. n. Measurements. TL: 3.4–3.6 mm, MW: 1.7–1.85 mm, TL/MW: 1.94 –2.00, IO/MP: 0.46–0.48. Distribution. So far known only from the locus typicus near Sivrikaya in the Rize province, north-eastern Turkey (locality 5 in Fig. 13). Derivatio nominis. The specific name sivrikaya is a noun in apposition and is derived from Sivrikaya, the village which is situated near the locus typicus of the new species.Published as part of Fery, Hans & Erman, Ömer Köksal, 2009, Five new species of the longulus - group of Hydroporus Clairville, 1806 from north-eastern Turkey (Coleoptera: Dytiscidae), pp. 1-12 in Zootaxa 2033 on pages 6-7, DOI: 10.5281/zenodo.18632
