Ornithodoros mimon is an argasid tick common on Chiroptera in the Neotropical region, where it also bites humans aggressively. Here we describe for the first time all nymphal instars (N1, N2 and N3) of O. mimon based on optical and scanning electron microscopy. Although the nymphal instars of O. mimon resemble each other closely, there are characters that differentiate them: the N3 are taller that N1 and N2; the genital primordium occurs in some N2 and all N3; the spiracular plate in N1 and N2 is cone-like, but in N3 it is semicircular; and the submarginal dorsal groove is less distinct in N1 but more evident in N3. Nymphs of O. mimon closely resemble the bat-associated species of the genus Ornithodoros included in the Alectorobius group. We review prior descriptions of nymphs of the Alectorobius group and make comparisons with nymphs of O. mimon, highlighting characters with diagnostic information, such as the idiosomal shape, presence of discs and hood and absence subapical protuberance of tarsus I. The description of nymphal instars of O. mimon herein presented, improves the taxonomy of the family Argasidae, performing a work more detailed about the immature stage of this species. (AU)
