Description
Summary: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.205110 : {"references": ["Nilsson, A.
