Synonyms and other taxonomic changes

All three species of North American Thiodina have actually been transferred to the genus Colonus(1)(2), however we are not sure which subfamily that genus fits in at the moment, so we have not changed the taxonomy on BugGuide yet. I asked Wayne Maddison for some guidance and he let me know that two papers are coming out soon which will completely explain the relationships and act as a guide for us. -Mandy Howe, Oct. 15, 2015

Thiodina sylvana males look superficially the same as the males of this species but can be separated in the field by the type of white patch in the middle of the carapace. T. puerpera has a longitudinal white stripe that reaches almost to the posterior edge of the carapace. In contrast, T. sylvana's white patch is circular or squared.
