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.
