Pronotum with 6 pairs of very long setae; without paired postero-median discal setae. Metanotum with weak reticulate sculpture, campaniform sensilla absent, median setae arising at anterior margin.

Related and similar species

In this essentially Old World genus 14 species are currently recognised (Mound, 2011), but S. longicornis cannot at present be distiguished satisfactorily from dilongicornis from China, and takahashii from Taiwan. Females identified as this species from California cannot be distinguished from females of longicornis from Europe, but the males from California are macropterous, whereas the available males from Europe are all hemimacropterous.
