Sinella gei Pan, Zhang & Shi, 2012

Figs 4 , 41–42 , Table 2

Type locality. China, Qinghai, Xining.

Material examined. Male holotype and 2 female paratypes; female on slide and 2 in alcohol, China: Liaoning Province: Shengyang City: Zhaoling Mausoleum of the Qing Dynasty, 41.850°N, 123.428°E, alt. 58 m, in the litter under buddhist pine trees, 15.viii.2014, F Zhang, DY Yu and ZH Li leg. (# 14SY).

Additions to original description. Clypeal chaetae 8 and arranged in three rows, 3 of them ciliate and smaller ( Fig. 41 ). Cephalic groove with 7 chaetae, anterior four smooth and posterior three ciliate; the anterior two ciliate ones much smaller ( Fig. 42 ).

Distribution. Qinghai, Liaoning.

Remarks. All three 5+5 eyed species of Sinella share eye arrangement (D, G, H absent), rod-like chaetae 2 and 3 on Ant. III organ, lateral process of labial palp exceeding the papilla, ciliate post-labial chaetae X, X2, and X4, three inner ungula teeth and a large outer tooth on unguiculus, “smooth” inner differentiated tibiotarsal chaetae, absence of smooth chaetae on manubrium, smooth part of dens slightly longer than mucro, short mucronal spine, 5 sutural cephalic mac, 3 medio-medial and 3 medio-lateral mac on Th. II, 1+1 central and 3+3 lateral mac on Abd. III, and 7+7 central and 6+6 lateral mac on Abd. IV. S. gei can be separated from the others by chaetotaxy of Th. II– Abd. II ( Table 2 ). The distance between antero-lateral S-chaetae ms and sens is longer than in other Sinella species.
