Differential diagnosis

This species resembles D. longa sp. nov. ( Figs 2–3 View Fig View Fig ) in having a longer tibia (longer than half the length of the cymbium), the fingernail edge-shaped basidorsal fold (BF) of the cymbium and similar spermathecae, but it differs by having the palpal tibia shorter than the length of the cymbium ( Figs 8A– C View Fig , 9C–E View Fig , 10C–E View Fig ) (vs as long as the cymbium, Figs 2A–C View Fig , 3C–E View Fig ), the anterior side of the mesal process of the conductor posterior arm with smooth tip ( Figs 8B View Fig , 9D View Fig , 10D View Fig ) (vs has a notch, Figs 2B View Fig , 3D View Fig ), and the septum 3 times as long as wide ( Figs 8D View Fig , 9F View Fig , 10F View Fig ) (vs 2 times as long as wide Figs 2D View Fig , 3F View Fig ).

Remarks

We presented the photographs of specimens of Devade qiemuensis collected from Qiemo County (type locality) and Inner Mongolia. While variations were observed in the septum of the epigyne among the female specimens, no differences were noted in the male specimens collected alongside the females in Inner Mongolia.
