Kirirom N.P., about 630 m, small lake near Old Kirirom Pagoda surrounded by pine forest, 11°19’47’’N / 104°02’14’’E, 2.XII.2019, W. Rossi’ [w, p]’ ( NMNHS, cDW, cGI) .

TME: 3 specimens. TGE: 1♂, 1♀.

Diagnosis. The new species is readily distinguished from S. kalimantanensis by its ovate and rounded prosternal process apex, nearly smooth pro- and metepisternum, and smaller PW/PA, EL/EW and EL/PL ( Figs 14D, E , Table 3).

Description. Habitus. Specimens of average size (BL: 10.8–11.0 mm, BW: 4.65–4.80 mm), with subovate, moderately convex body ( Fig. 14A ). Ratios and measurements. See Table 3. Color and luster. Body black dorsally and ventrally; antennae, palpi, tibiae and tarsi piceous to rufopiceous. Integument dorsally and ventrally moderately shiny, without iridescence. Punctuation. Dorsal surface without punctuation except posterolateral parts of pronotum, which have large but very shallow punctures extending laterally to pronotal posterior half; sides of prosternum and base of mesoepisternum with some macropunctures; sides of metasternum and metepisternum with several scattered and coarse punctures; abdominal ventrite 1 at base, 2–6 at sides and 6 at apex with somewhat finer punctures. Head. About half as wide as pronotum or less (PW/HW: 2.02–2.09). Mentum tooth with apex widely rounded and distinct paramedial border ( Fig. 14C ). Thorax. Pronotum ( Fig. 14B ) with sides weakly rounded toward posterior angles (PW/ PB: 1.02); maximum width near posterior angles; laterobasal impressions indistinct. Prosternum without median longitudinal sulcus; prosternal process ovate, with rounded apex, throughout bordered ( Fig. 14D ). Metepisternum longer than wide (MA/MM: 0.84–0.86), nearly smooth, coadunation with epipleuron very short, located anteriorly ( Fig. 14E ). Elytra. Apical sinuation moderate to strong, well-defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola and striae in anterior half of elytron punctate. Intervals 1–7 rather flat to subconvex, interval 8 rather convex. Legs. Protarsomeres 1–3 of male moderately dilated, with second segment as wide as long (W/Lp2: 1.00). Male genitalia. Median lobe ( Figs 14F, G, H ) with angle between basal bulb and shaft acute; shaft moderately swollen; apex straight; apical lamella bent to left and rounded at tip. Female genitalia. Basal gonocoxite with several lateroapical setae, without medioapical setae. Apical gonocoxite elongate, with two small dorsolateral ensiform setae and dorsomedial ensiform seta located near base ( Fig. 14I ). Seminal canal not twisted apically; spermathecal gland without atrium ( Fig. 14J ).

Etymology. The species is named for the Hainan Island, located in the South China Sea, where the holotype was collected.

Distribution. China (Hainan Province), Cambodia (Koh Kong Province).

Bionomics. The holotype was collected under a light trap near a pond in Hainan Province . The specimens from Kirirom National Park, Cambodia, were collected by throwing water on the banks of the lake in daytime .
