Polyphylla concurrens Casey Materials examined. GUATEMALA, El Quiché: Chichicastenango, central market, 10.X.1998, H. E. Mayne (1 male, DALC). Remarks. This species was originally described from Honduras (Casey 1889, 1914). Morón (2010, 2015 in litt.) records it from the states of Chiapas, Morelos, Oaxaca, Puebla, and Vera Cruz, Mexico. Accounting for phenotypic variation and sexual dimorphism (the holotype is a female, #35640, United States National Museum), the specimen cited above agrees in all essential morphological respects to Casey (1889, 1914) and Morón (2010, 2015 in litt.).
