Floral association: Ligularia sp. ( Asteraceae ).

General distribution: China (Yunnan, Sichuan) .

Remarks: This species appears close to B. atriceps . Bathanthidium rubopunctatum differs from B. atriceps in larger size, coarser tergal punctation, T7 medial projection triangular point with lateral shoulders, propodeal triangle with rather wide, sparsely punctate area (as opposed to punctures restricted to small area medially), and ocelloccipital distance>2.5 times lateral ocellar diameter (compared to 2 or less). The female differs from females of B. atriceps in: terga more densely punctate throughout including maculations (as opposed to very sparse in maculae), mandible with 3 rd tooth more than 2x as far from dorsal tooth as from 2 nd tooth, ocelloccipital distance> 3x ocellar diameter (compared to slightly more than 1x).
