Hydroporus hajeki sp. nov.

Type locality. Iran, Ardabil province, Jebal-e Sabalan mountain [= Kühha-ye Sabalan], Qutur Su [= Guter-Su = Ghotur Suei], ca. 40 km due WNW Ardabil, ca. 38.325N 47.842E ; ca. 2725 m a.s.l. {7}.

Type material. HOLOTYPE: J, ‘ Iran, Ardabil prov., 5.VI.2006, Qutur Su (sulphureous springs), ‚ Jebal-e Sabalan‘ Mt. , 38°19,6‘N 57°50,5‘E; 2725 m, Jiří Hájek & Pavel Chvojka leg.’ [printed] {7 }, ‘ Holotype, Hydroporus hajeki sp. n., H. Fery det. 2009’ [red, printed] ( NMPC) . PARATYPES: IRAN: 6 JJ, 4 ♀♀, same collecting data as the holotype ; each paratype provided with a red printed paratype label ( NMPC, CHF) .

Differential diagnosis (given chiefly as differences from H. jelineki sp. nov.). Externally very similar to H. jelineki sp. nov. Punctation on elytra on average slightly coarser and less dense, puncture lines more distinct. Upper surface black except vertex of head and posterior part of pronotal rim. Darkening of middle of femora rather inconspicuous in most specimens.

JJ. Median lobe ( Fig. 6 ) in ventral view more or less evenly tapering to apex, tip rather broadly rounded. Paramere as in Fig. 13 . Sucker cups on first tarsomere of pro- and mesotarsomeres present.

♀♀. See remarks under H. jelineki sp. nov. Gonocoxosternum and gonocoxae as in Figs. 19 and 24 .

Measurements. TL: 3.3–3.7 mm, MW: 1.65–1.85 mm, TL/MW: 1.97–2.03, IO/MP: 0.46–0.50.

Variability. Only variability in size noticed in the type series.

Distribution. So far known only from the type locality in the Ardabil province, north-western Iran ( Fig. 26 ).

Biology. Sabalan is ‘an isolated volcano with lots of springs, some of them sulphurous’. The specimens were collected in a bog with small pools (5–20 cm in diameter) near a non-sulphurous spring on the slopes of the mountain (J. Hájek, personal communication; see Figs. 29–30 ).

Etymology. This species is named after my friend Jiří Hájek (Prague, Czech Republic) (noun in apposition in the genitive case).
