Treatment

Subgenus Hyphoporus Sharp, 1880 n View in CoL . stat.

Type species: Hydroporus solieri Aubé, 1838: 554 , by monotypy.

The subgenus Hyphoporus contains 19 species distributed in the Oriental and Palaearctic regions (see Fig. 2 View FIGURE 2 and Table 1).

Diagnosis. Body shape short oval (TL/MW ca. 1.6–1.7), rather globose; small to medium sized species (TL 3.5–5.6 mm) (see Fig. 18 View FIGURES 13 – 18 for H. (Hyphoporus) solieri ). Head with anterior clypeal margin truncate, straight or slightly emarginated, border not produced forwards; bead continuous, middle part narrowed in most species (see Fig. 42 View FIGURES 41 – 48 for H. (Hyphoporus) solieri ); (eXcept H. (Hyphoporus) bengalensis (Severin, 1890) with continuous bead). Antennomeres simple, not broadened. Elytra with margin in lateral view moderately ascending to shoulder (similar to Fig. 55 View FIGURES 49 – 55 ); epipleuron comparably broad, broader than mesotibia distally; carina meeting inner margin of epipleuron forming a comparably small angle (<ca. 135°; similar to Fig. 50 View FIGURES 49 – 55 ). Elytra with interrupted vittae or dotted (in some species very darkened); venter black or brown. Last abdominal ventrite without deep depression. Aedeagus with median lobe robust, asymmetric (see Fig. 28 View FIGURES 19 – 28 for Hygrotus (Hyphoporus) tonkinensis (Régimbart, 1899) ; in H. bengalensis median lobe more or less symmetric; see Vazirani 1969 for several further figures); parameres with condylar process of diverse length, forming an obtuse angle with distal part (see Fig. 40 View FIGURES 29 – 40 for H. (Hyphoporus) tonkinensis ). Male metatarsal claws of equal length.

Distribution. Palaearctic and Oriental, from Iran to India and south-east Asia; one species– H. (Hyphoporus) solieri –from Iran to the Arabian Peninsula and Egypt.

Main habitat types. There is no information on the habitat of most of the species of the subgenus, although they are likely to be mostly associated with freshwater environments. However, it shall be mentioned that Hájek (2006: 48) illustrated a rest-pool in a wadi (Pir Sohrab, Iran) where he has collected H. (Hyphoporus) aper ( Sharp, 1882) together with Neptosternus circumductus Régimbart, 1899 .
