Diagnosis
Males of Tafana arawak sp. nov. resemble others of the silhavyi group by a laminar and coiled apophysis at the base of the embolus, but differ by the retrolateral tibial apophysis bifid ( Fig. 27C–E View Fig ). Females resemble those of T. silhavyi and T. maracay sp. nov. by the epigynal plate with wide atrium, but differ by the atrium extremely wide and the large hood ( Figs 27F–G View Fig , 33E View Fig ).
Etymology
The specific name is derived from the Brazilian Portuguese word ‘Aruaques’ (in Spanish ‘Arahuaco’) for the name of an indigenous group from the Americas, named ‘Arawak’, meaning ‘flour eater’. The name should be treated as a noun in apposition.
