Pygofer side with several rigid setae of different sizes scattered on distal part and group of medium sized setae gathering at cephalo-ventral angle (Fig. 5a). Pygofer ventral appendage with apex exceeding posterior margin of pygofer lobe (Fig. 5a). Subgenital plate expanded subbasally and contracted medially, with 4 macrosetae medially, row of microsetae along outer margin from subbase to apex, subbasal microsetae larger and forming a group (Fig. 5a). Style apex foot-like with short acute heel and quite short toe (Figs 5e, f).

Measurement. Male 3.13–3.15mm, female 3.18–3.20mm.

Material examined. Holotype: ♁, CHINA, Hunan Prov., Chenzhou, 2020.VII, coll. Deliang Xu; Paratypes: 2♀, same data as holotype .

Remarks. This new species is similar to S. fujiwara, but has the aedeagal dorsal apodeme rudimentary, the aedeagal shaft inverted S-shaped and the connective with central lobe developed.

Etymology. This specific epithet combines the Latin “lamella” and “penis”, referring to the extremely compressed aedeagal shaft.
