Spikethumb frogs are a genus (Plectrohyla) of frogs in the family Hylidae found in Central America from southern Mexico through Guatemala and northern El Salvador to central and northern Honduras. A major revision of the Hylidae moved an additional 21 species to this genus from the genus Hyla.[1] They are called spikethumb because of the spike on their thumbs, which is called a prepollex. The genus name comes from the Greek word plēktron ("spur")[2] and hyla (the genus in which it was formerly placed).
