Description

provided by Zookeys
“Body broadly ovoid and parallel-sided. Antenna distinctly clubbed with antennomeres symmetrical [S. jurassica: “weakly asymmetrical”; S. amoena: “strongly asymmetrical”]; antennal insertions visible in dorsal view. Eyes convex. Frontoclypeal suture present. Antennal grooves present and parallel. Anterior pronotal angles well developed and subrounded. Mesoventrite not vaulted. Mesocoxae widely separated [see “note” in Remarks]. Metaventrite lacking axillary space and metakatepisternal suture. Metacoxae not excavate and narrowly separated. Elytra with seriate punctation (in one fossil). Abdominal ventrite 1 about as long as 2, intercoxal process narrow. Body length 7.5–7.6 mm, width 4.5–4.8 mm.” (Diagnosis of the genus according to Yu, Leschen, Ślipiński, Ren & Pang 2012.)
