The genus Siragra differs from the genus Bracodoryctes (both lacking the occipital and hypostomal carina even if they belong to different tribes) by the apical lobe and additional carina on scape, the propodeal bridge distinct, the hind coxa without basoventral tooth and the basal ring of the male genitalia without dorsal bridge.
