Distribution. Philippines.

Remarks. Ban & Ishikawa (2013) redescribed this species, S. valdezi , without resorting to the examination of the types. During the present study two type specimens (lectotype male and paralectotype female, designation here) of S. valdezi borrowed from MZH were examined. These specimens did not match the redescription provided by Ban & Ishikawa thereby alluding that this was a case of misidentification. The species that was considered S. valdezi by Ban & Ishikawa is indeed an entirely different and undescribed species, that is described herein as S. planus sp. nov. below.

S. valdezi is similar to S. validus , but differs from the latter in the following combination of characters: female anterior pronotal lobe: posterior lobe 1:2 (vs. 1: 1.5 in S. validus ) ( Figs. 1a ; 6a ); tibiae without any annulations (vs. with two dark annulations); posterior margin of sternite VI straight (vs. weakly convex at middle) ( Figs. 4f ; 6c ); middle margin of two halves of sternite VII distinctly curved laterally and overlapped (slightly overlapped) ( Fig. 6c ); the shapes of paramere and median projection of pygophore are also different ( Figs. 1e ; 5c).
