Material examined: 1 Ψ, Laos, Vientiane prov., Ban Van Eue, 30.XI. 1966, native coll., Bishop.
Comments: This specimen has all the characteristics of S. outouana, except that it is much larger (4.17 mm) and its rostrum reaches the hind coxae and almost the abdomen. It is closely allied to S. chinensis Drake but has divergent hemelytra. It is also closely allied to S. bhutanensis Péricart but has also divergent hemelytra and a longer fourth antennal segment. This single specimen cannot justify the description of a new species and is therefore considered provisionally as S. outouana. This species is known by the type series from China (Fukien).
