Genus Platycesta Viswajyothi & Clark, 2021

Platycesta Viswajyothi & Clark, 2021b: 474

(type species Monocesta depressa Clark, 1865 , by original designation).

Remarks

This genus includes just one described species, P. depressa ( Clark, 1865) , which is distributed in Central America and northwestern South America. Although it has been reported from the United States ( Kim et al. 2003), this was surely in error. See Figs 2 and 152 for a habitus illustration and details of morphology.
