Rhicnosthetus rondoni Hoffman, 2006: 52 , figs. 21–25 (Male holotype and three males paratypes from Nova Esperança (-8.727772°; -63.867630°), Porto Velho, Rondônia, Brazil, 6-8/XII/1983, P.E. Vanzolini coll., deposited in MZSP, not found; male paratype from Nova Brasília, Ji-Paraná (-10.886901°; -61.913764°), Rondônia, Brazil, 6-11/XI/1984, P.E.

Material examined: BRAZIL. Mato Grosso: Aripuanã (-10.654524°; -59.915741°), Mata margem e s q u e r d a d o r i o A r i p u a n ã, j u s a n t e d o S a l t o d e Dardanelos, 2M, VII/2003, C. Strussmann coll. ( CZUFMT-MYR 864).

Diagnosis: Males of R. rondoni differ from all other species of the genus based on the combination of gonopodal characteristics: prefemoral process reaching half the size of the acropodite ( Fig. 3c ) and falciform acropodital process exceeding the size of the solenomere ( Fig. 3b ).

Distribution: Known from the states of Mato Grosso and Rondônia, Brazil ( Fig. 11 ).
