Similar to S. grande in most respects, but differs in the following characters: body form distinctly elongate; pronotum more convex; antennal club (Fig. 21) slenderer; male metasternum with larger setal patch; punctation of pronotum slightly finer and sparser; male profemora (Fig. 22) longer and slenderer, tubercles smaller; male protibiae (Fig. 22) longer and more incurved with a small subapical expansion and an apical angle on inner side; internal sac of aedeagus as in Figs 19, 20.

Diagnoses. This species can be easily distinguished from other related species by the elongate body.

Etymology. The Latin adjective “ longum ” refers to the elongate body and male legs of the new species.

Biological notes. All specimens were collected from a log covered with white fungus (Fig. 43). Territorial behavior of the male was observed by the collector, and it was described as follows: Each male occupies a small area on the fungi. Normally they highly raise bodies upon their long legs and they can shake their bodies up and down rapidly. Once, a small male was too close to a large one, the large male rushed to it immediately and the small male retreated quickly, without having body contact.
