Male holotype from Parque Nacional da Serra do Divisor , Cruzeiro do Sul , Acre , Brazil [ 07°40’S , 72°39’W ], 20.III.1997 , L. Resende & S. Vieira leg . ( IBSP 12253 ). Paratype : one female , same locality and data as holotype ( MCTP 33352 ) . Etymology. The specific name is a noun and refers to the type locality. Diagnosis. The males of T. acreana sp. nov. ( Fig. 130 ) resemble those of T. onca sp. nov. in the divided apex of the median apophysis ( Fig. 112 ), but can be distinguished by a prolateral expansion on the median apophysis ( Fig. 131 ), by the short and thick tip of the ental branch of RTA ( Fig. 132 ) and by the blunt projection at the base of EnB ( Fig. 133 , white arrow). The females resemble those of T. caracarai sp. nov. ( Fig. 119 ) in the excavated middle field of the epigynum, but can be distinguished by the wider copulatory ducts and slender head of spermathecae ( Fig. 135 ). Description.
