Comments.

Fouts (1948) described Trimorus pulchricornis and T. varius in the same publication, which also included T. annulicornis in his key to species. Even a cursory examination suggests that these three belong to a single species, giving us serious doubts about the quality of Fouts’s taxonomy, at least as far as Trimorus is concerned. We suspect that many more of Fouts species of Trimorus will be treated as junior synonyms but will require more thorough study that is beyond the scope of this publication.
