Semimesoleius Ozols, 1963
According to Townes (1970), Semimesoleius is quite similar to Mesoleius, Campodorus, and Alexeter. In his key to mesoleiine genera, Townes (1970: 105-109) characterizes Mesoleius and Campodorus by the absence of a fore wing areolet relative to Semimesoleius. Alexeter and Semimesoleius are differentiated by the size of the ocelli, though it should be noted that some species of Alexeter have fairly large ocelli. Semimesoleius could also easily key to Lamachus in Townes’ couplet 19.
The above information is based almost exclusively on descriptions, keys, and figures in Townes (1970) and Kasparyan and Khalaim (2007) since I have not seen any material of this genus.
There are no specimens currently determined for this OTU, or those specimens determined for this OTU are not yet mappable.
This work would not have been possible without the groundwork provided by Ian Gauld’s study of the Australian and Costa Rican faunas, and we are particularly grateful for his assistance in many aspects of this study. We also thank David Wahl for useful feedback throughout our study. Matt Yoder provided considerable assistance with databasing issues, and our use of PURLs (http://purl.oclc.org) in this regard follows the example of their use in publications by Norm Johnson. Heather Cummins and Caitlin Nessner graciously assisted with formatting, and literature retrieval. This study was supported by the National Science Foundation’s PEET program under Grant No. DEB 0328922 and associated REU supplement nos DEB 0723663 and 0923134.
