Diagnosis.The copulatory organs of this species are very similar to those of T. leighi( Peckham & Peckham, 1903)but the latter species is easily recognized by the characteristic coloration (Wesołowska 2012: fig. 53). T. alotamais also related to T. aurantiaca(Simon, 1902)and T. fidelis Wesołowska & Haddad, 2009, but can be recognized by the shape of the retromarginal tooth of the chelicerae and the striped pattern of the abdomen. The female has longer seminal ducts than T. aurantiacaand larger spermathecae than T. fidelis(compare Fig. 175herein with Fig. 183herein and in Wesołowska & Haddad 2009: fig. 199). The male palp is very similar to those in both of these species and is difficult to distinguish, but the tibial apophysis has a serrated rim.
Etymology.The specific name is anagram of Amatola, the mountain range where the species occurs.
