More similar to detrita in my view than to obydovi. "A. detrita differs from A. obydovi by bigger average body size (lenght from 13 to 21 mm) presence of numerous long erect black setae along elytral surface; black setae tibiae brushes; much denser yellow pubescence on ventral body side, totally hiding punctuation; parameres distinctly longer with longer setae; apex of aedeagus slightly bent dorsally and a little less pointed". - from original description.
