Satonius schoenmanni sp. nov.

( Fig. 7 )

Type locality. China, Hunan province, ca. 25 km N Pingjiang, ca. 28°50′10″N, 113°38′05″E, ca. 200 m a s.l.

Type material. HOLOTYPE: J ( CASS), ‘ CHINA: Hunan, 20.3.2003 / ca. 25 km N Pingjiang City , 113°38′05″E 28°50′10″N / ca. 200 m, leg. Schönmann, / Komarek & Wang (CWBS 499) ’. PARATYPES: 3 ♀♀, same label data as holotype ( CASS, NHMW, NMPC).

Diagnosis. Small and broad species; body length 1.6 mm, width 1.0 mm. Sides of pronotum broadly bordered. Lateral margin of elytra visible only in humeral part. Brachypterous species; hind wing membranous, 0.35 mm long (elytron 1.00 mm long), venation reduced.

Male genitalia. Median lobe of aedeagus with dorsal side slightly rounded in basal two thirds, straight in apical third; ventral side slightly concave, apex with minute hook. Parameres rather wide, with four long setae apically, base with short field of pores along ventral surface ( Fig. 7 ).

Bionomics. At the type locality, water beetles were collected in a 3-5 m wide stream with boulders on cliffs, between sparse riparian vegetation and in flood debris (H. Schönmann, pers. comm. 2008). No detailed data on the precise microhabitat of this species are known.

Etymology. The new species is dedicated to one of its collectors, Heinrich Schönmann (NHMW), a specialist on the Hydrophilidae .

Distribution. So far known only from the type locality in Hunan province, China ( Fig. 32 ).
