( Figs. 1 , 5 , 10 ) Type locality. China , Yunnan province ,Shanzhi env., Jizu Shan Mt., Jade Dragon waterfall, ca. 27°57.6′N , 100°23.2′E , 2250 m a.s.l. Type material. HOLOTYPE : J ( NMPC ), ‘ CHINA : Yunnan province , / SHANZHI env., 23.-24.VI.2007 , / JIZU SHAN Mt., / Jade Dragon waterfall / 27°57.6′N 100°23.2′E , 2250 m , / J. Hájek & J. Růžička leg. ’ PARATYPES : 10 JJ 5 ♀♀ and 26 unsexed spec., same label data as holotype ( BMNH , CASS , CZUG , KSEM , NHMW , NMPC , TMSA ). Diagnosis. Large and elongate species ( Fig. 1 ); body length 2.0- 2.4 mm , width 1.2-1.4 mm . Sides of pronotum narrowly bordered. Lateral margin of elytra visible in dorsal view only in basal fifth. Macropterous species (for description of hind wing venation see generic description, Fig. 5 ). Figs. 6-10. Aedeagus and details of parameres of Satonius Endrödy-Younga, 1997 in lateral view. 6 – S. kurosawai ( Satô, 1982 ) ; 7 – S. schoenmanni sp. nov. ; 8 – S. wangi sp. nov. ; 9 – S. sp. 1; 10 – S. stysi sp. nov. Scales: a – aedeagus; b – detail of paramere. Male genitalia. Median lobe of aedeagus evenly curved to apex. Parameres long and narrow, with four long and two shorter setae apically, base with short field of pores along ventral surface ( Fig. 10 ). Bionomics. Satonius stysi sp. nov. was collected in hygropetric habitats in the spray zone along the Jade Dragon waterfall and on a seepage near the waterfall but not connected to the stream ( Figs. 3-4 ). Both microhabitats had only a thin film of water (up to 2 mm ) and were covered with a macroscopic algal mat. The new species was collected together with unidentified species of Anacaena Thomson, 1859 (Hydrophilidae) and Cephalobyrrhus Pic, 1923 (Limnichidae) . Etymology. The new species is dedicated to Prof. Pavel Štys (Charles University, Prague , Czech Republic ), our teacher and a specialist on the Heteroptera. Distribution. So far known only from the type locality in Yunnan province , China ( Fig. 32 ).
