Key to Mexican species of Plega View in CoL View at ENA
(Modified from Ferris 1940; Linsley & MacSwain 1955; Rehn 1939; Parker & Stange 1965; Rice 1987).
Note: This key was produced only to identify male specimens of Mexican species of Plega . Females were obmitted, since none of the North American species of this genus have been described from this sex.
