Two new species of the genus Caloxiphus Saussure & Pictet, 1898 (Pseudophyllinae) are described: C. chapulhuacan n. sp., and C. cuicani n. sp., both endemic to the Huasteca Region, State of Hidalgo, Mexico. These two new taxa show morphological affinities to C. championi Saussure & Pictet, 1898. However, they may be separated from the latter species on basis of external and internal (genitalia) morphological characters that are provided and illustrated. Acoustic signals for C. cuicani n. sp., and information on distribution for both new taxa are given.
