Status Not mentioned in the literature after the first description. If accepted, a combination with the genus Trigonipraxis is likely. Although this combination has never been established, it was implied by Starobogatov (1970), who introduced Trigonipraxis for the group "Triangulares" of Andrusov (1897), which included Congeria waehneri.
