Comments. This species is still known only from the types. It is most similar to E. pilulifera and E. clypeata , sharing the small size; a similar arrangement and number of erect setae, these almost circular, nearly as broad as wide; and abundant ground pilosity that is strongly flattened and conspicuous. Eurhopalothrix clypeata has a transverse carina on the clypeus. Eurhopalothrix pilulifera has the propodeal spine in the form of a rectangular lamella extending down the posterior face of the propodeum (propodeal spine acute in E. alopeciosa , with narrow infradental lamella). Eurhopalothrix xibalba is larger and has thinner ground pilosity. Measurements for this species, from Brown and Kempf ( 1960), are HW 0.50–0.53, HL 0.52, SL 0.32, CI 96.
