Figs 6 , 43–47

Type locality. China, Shangdong, Qufu.

Material examined. Holotype and paratypes; 2 females on slides and 1 in alcohol, China: Jilin Province: Changchun City: Northeast Changchun City Urban Wetland Park, 43.986°N, 125.36°E, alt. 217 m, 31.viii.2013, in litter, F Zhang and X Sun leg. (# 2013 DBCC).

Additions to original description. Ant. III organ with 2 rods; chaeta 6–9 as ordinary smooth chaetae ( Fig. 43 ). Clypeal chaetae 9, all smooth, 5 of them much smaller ( Fig. 44 ). Post-labial chaetae H1, X, and X2-4 ciliate; X3 sometimes absent. Cephalic groove with 8 chaetae, the first (G1) and the third ciliate. Trochanteral organ with 13– 15 spiny chaetae, 10–13 in arms and 2–3 between arms ( Fig. 45 ). Ventral tube anteriorly with 7+7 ciliate chaetae ( Fig. 46 ); posteriorly with 12 smooth chaetae; each lateral flap with 8 smooth chaetae ( Fig. 47 ). S-chaetotaxic formula 2, 2/1, 2, 2, –, 3 sens, 1, 0/1, 0, 0 ms.

Distribution. Shandong, Jilin.

Remarks. S. qufuensis is the only 4+4 eyed species from China. It differs from another 4+4 eyed species, S. humicola Brown, 1926 from Iraq, in having an outer tooth on unguiculus and the absence of “smooth” inner differentiated tibiotarsal chaetae.
