Hydroporus discretus tatricus KINEL 1949 (status restored)

Hydroporus discretus tatricus KINEL 1949: 396 (orig. descr.), HOCH 1967: 253, IENIŞTEA 1978: 297.

Hydroporus discretus FAIRMAIRE & BRISOUT : GALEWSKI 1971: 14 (new synonymy), NILSSON 2001: 156.

T y p e l o c a l i t y: Poland,Tatramountains.

L e c t o t y p e (by present designation):, " Halicia [= Galizien ; historical landscape in SE Poland and W Ukraine] occ., Tatra 25/7, S. Stobiecki. " [hw?], "tatricus n. sp. " [hw?], " Co-Typus " [red, unauthorised curatorial designation], " Lectotypus, Hydroporus discretus tatricus Kinel 1949 , des. H. Fery 2005" [red, printed] ( NMW) .

P a r a l e c t o t y p e s: 3, 3, same label data as the lectotype, but provided with the respective red paralectotype label (NMW). 1, "Halicia occ., Tatra 25/7, S. Stobiecki." [hw?], "tatricus n. sp. " [hw?], " Hydroporus tatricus Stob. , n. sp. " [hw?, same as on the first label], "Typus" [red, unauthorised curatorial designation], " tatricus, Galiz. [= Galizien] Stob." [hw?], and a red paralectotype label (NMW).

N o t e s: The lecto- and paralectotypes designated above are those specimens of which KINEL (1949: 396) reports that he has found them with the labels cited above in the "Naturhistorisches Staatsmuseum à Vienne " (= NMW). He has also studied other specimens collected by Stobiecki ("... repandu dans mainte collection privée ...") and in particular 15 specimens collected by M. Rybínski in the Tatra mountains at "Zielony Staw Gasienicowy" which were stored in the "Musée d’histoire naturelle de l’Académie des Sciences Polonaise à Cracovie [Kraków]". We were not able to study these specimens, however, they have to be considered as paralectotypes nevertheless.

Descriptive notes: The specimens studied are somewhat broader and slightly more depressed than H. discretus from e. g France and Germany, and thus resemble on a first glance H. macedonicus . The habitus, however, is distinctly more evenly rounded and less stout than in the new species. The elytral base bears up to three light brown to almost yellowish, but confused and indistinctly delimited spots, extending in some specimens internally as far as the suture; the sides of the elytra are – in particular in the posterior third – somewhat lightened; the rest of the elytra is of a blackish brown, while the pronotum is black, except – in a few specimens – the brownish lateral bead. The aedeagus is similar to that of H. discretus from other regions.

Measurements: TL: 3.2–3.3 mm, MW: 1.7–1.8 mm; TL/MW: 1.83–1.94.

Notes: GALEWSKI (1971: 14) treated Kinel’s taxon as a synonym of H. discretus without giving any reason for this. With respect to the considerable external differences to typical H. discretus discretus from France (locus typicus: "Marly", ca. 200 km NNE Paris; see BALKE & FERY 1993) we propose to revoke Galewski’s synonymisation and to keep the original status of H. discretus tatricus until the Polish and further European population have been investigated by means of molecular methods.
