The genus Hydroporus in Turkey

Darılmaz & Kıyak (2009) recorded 25 Hydroporus from Turkey. In their work the authors included chiefly records found in the literature and only little material collected by themselves. They did not include H. angustatus Sturm, 1835 , and H. dobrogeanus Ieniştea, 1962 (cf. Nilsson 2011). Other species not included are those seven species of the longulus -group which have been described after the publication of that work ( Fery & Erman 2009 and Fery 2009), and H. kurdistanicus Hájek & Fikáček, 2010 . Hydroporus memnonius was also not mentioned in their work. On the other hand, the authors recorded H. jacobsoni Zaitzev, 1927 , H. limbatus Aubé, 1838 (in both following Guéorguiev 1981) and H. tristis (Paykull, 1789) (following Zimmermann 1931). We are sure that the latter three species do not occur in Turkey because:

- All H. jacobsoni recorded from Turkish territory by Guéorguiev (1981: 407) have been examined by us and proved to belong to H. dobrogeanus .

- Hydroporus limbatus is a Western Mediterranean species which does not occur in the Eastern Mediterranean, where it is replaced by H. brucki Wehncke, 1875 .

- Zimmermann (1931: 105) indeed recorded H. tristis from "Kleinasien" [= Asia Minor] (and no doubt Guignot 1947: 93 as well as Franciscolo 1979: 359 repeated his record without having seen themselves any material from Turkey). We have found two specimens in the ZSM which certainly are those which Zimmermann induced to record that species from Asia Minor. The label data, however, lead us to assume that Zimmermann had been deceived when acquiring these specimens. Both have printed labels with " Asia minor, Karakeuy" and "v. Bodemeyer". Karakeuy is the type locality of H. bodemeyeri Ganglbauer, 1900 (Karakeuy = Karaköy in Bilecik prov., ca. 22 km S Bilecik, ca. 39.57?N, 29.59?E; cf. Hájek & Fikáček 2010: 1642). In addition each specimen has a small round light blue-green label with "Cotype" in Zimmermann's handwriting, a printed label "Samml. A. Zimmermann" and a red printed label with "Cotypus" [most probably mounted by a curator of the ZSM in the late 20th century]. One of the specimens has an additional handwritten label "scheinbar ausgetauschte Tiere" [= seemingly exchanged animals/specimens] [handwriting unknown]. We assume that, originally, on both cards have been glued syntypes of H. bodemeyeri (cf. Miller & Fery 1995: 409) and that these have been afterwards replaced by two H. tristis . The latter species has a similar distribution in Europe and Asia to H. umbrosus and prefers the same habitats. There is no doubt that it does not occur in Turkey.

As already mentioned in the introduction the genus Hydroporus is now known to have 180 species world-wide. Nilsson (2011) lists only 31 species for the Turkish fauna, because H. esseri sp. n. and H. memnonius were not yet included, and H. jelineki Fery, 2009 was overlooked. Thus, we can finally conclude that to our present knowledge 34 species of the genus Hydroporus (two of them occurring in two subspecies) occur in Turkey.
