Type material. Holotype ♀, Cuba, Granma Province, Buey Arriba, San Pedro de Yabo [20°10'N 76°45'W], 18.XII.1994, coll. J. Rudloff ( ZMB 50607 ).

Etymology. The specific epithet refers to the Ministry of Science, Technology and Environment of Cuba (CITMA by its acronym in Spanish), for their constant support and contribution to research and care of the environment on the island.

Diagnosis. Females of T. citma sp. nov. can be distinguished by their spermathecae shape ( Fig. 7F). They resemble those of T. fidelcastroi sp. nov. but differ by the small stalk and equal lobes. Male unknown.
