Diagnosis

Males of T. maracay   sp. nov. resemble those of the silhavyi   group by having the apophysis at the base of the embolus laminar, but differ from the other species by having the retrolateral tibial apophysis short, curved apically and presenting a basal projection rounded ( Figs 25C–E View Fig , 26C View Fig ). Females resemble those of T. silhavyi   and T. arawak   sp. nov. by having the epigynal plate with a wide atrium, but differ by having the copulatory ducts slightly narrowing in the anterior region ( Figs 25F–G View Fig , 33D View Fig ).

Etymology

The specific name is a noun in apposition taken from the type locality Maracay, currently the capital of the State of Aragua in Venezuela.
