"The missing type specimen was collected at the same time and same place by the same
collector as the type of Tylobolus monachus, strong circumstantial evidence that both names
are based on the same species. Morever, the liklihood also exists that the "missing" type of
viduus is actually the type of monachus. An identical parallel occurs in the case of Euzonium
crucis and Hypozonium arnaudi (q.v. sub Octoglena bivirgata)."
