Abstract.4Descriptions and illustrations of some Lethaeini associated with Ficus spp.
in Mexico are presented. Notes on the biology of Cistalia pallidifemur Cervantes and
Gamez, Cryphula apicata (Distant), C. trimaculata (Distant), Neopetissius slaterorum
O'Donnell, Paragonatas costaricensis Distant, P. divergens Distant, and Petissius spinipes
(Stal), and their distribution, mainly within the Mexican Gulf Coast region, are included.
Cistalia pallidifemur, n. sp., is described and illustrated. All species included in this study
are considered facultative seed predators of figs.
