P a r a t y p e s: 5 ♂, 2 ♀♀, same data as holotype (5exx. SMNS, 2 exx. CRO) .

Description

Body length 3.7–4 mm. Proportions of holotype: length of head: 54; breadth of head: 58; diameter of eye: 24; length of antenna: 105; length of pronotum: 54; breadth of pronotum: 50; length of elytron: 65; breadth of elytra: 60; metatibia: 55; metatarsus: 35.

Differential diagnosis

This is another very small species, distinguished from the two species above and from S. riedeli n. sp. by the less transverse head with more rounded, less pronounced apico-lateral angles and by the dark femora, and from all other species by the aedoeagus.
