The male and the tritonymph of Ioanella mimon are described for the first time parasitizing to Mimon cozumelae from Yucatan, Mexico. Male of I. mimon is characterized by the presence of legs I with the tibia and tarsus fused forming a small complex devoided of apical claws, legs II–IV with two claws, setae vi at level of anterior end of genital plate, genital plate rounded with an anterior projection, all intercoxal setae short; while the tritonymph is characterized by the presence of legs I unequal; legs II–IV with 2-1-1 claws, and posterior region of dorsal idiosoma with 3 pairs of cylindrical and toothed setae. Additionally, we include new locality and host records for Eudusbabekia mimon which was also found on M. cozumelae. Both species were described originally in association with Mimon bennettii at Bartica, Guyana.
Myobiidae , Ioanella , Eudusbabekia , Phyllostomidae
The genera Eudusbabekia Jameson, 1971 and Ioanella Dúsbabek & Lukoschus, 1973, include species associated with Phyllostomidae bats. The former is conformed by 32 species (
Particularly Eudusbabekia mimon Fain, 1973 and Ioanella mimon (Fain, 1973) were recorded parasitizing to Mimon bennettii Gray, 1938 from Bartica, Guyana (
A total of five bats were captured inside two hollowness located at carretera Santa Elena-Loltún Km 56, Yucatán, México (20°17'25.0"N, 89°38'43.3"W, 98 m) (Fig.

Male (Based on 2 males). Body length 225 (223–228); wide 139 (125–152). Body 1.6 larger than wide. Dorsal idiosoma (Fig.
Gnathosoma. Normally developed, with a pair of ventral flat and retrorse processes as in the female (Fain, 1978) but slightly less pronounced.
Legs. Tibia and tarsus I fused forming a small complex devoid of apical claws (Fig.
Trytonymph (Based on 4 tritonymphs). Dorsal idiosoma. Posterior region of dorsum with 3 pairs of cylindrical and toothed setae: e1 14 (11–18), e2 15 (14–18), f1 14 (12–15) (Fig.
The male described in this study was determined as part of the genus Ioanella by the presence of legs I with the tibia and tarsus fused forming a small complex devoided of apical claws, legs II–IV with two claws, vi and sci thin and short, all intercoxal setae very short and the lacking of f2 (
The identification of males and tritonymphs as I. mimon was done correlating the presence of females on the same analyzed bats considering that myobiids exhibit high specificity to their hosts (
Comparing our male specimens with the female described by
This work represents the first description of a male of the genus Ioanella, and the second that describes a tritonymph for the genus; previously
Eudusbabekia mimon and I. mimon are two species of myobiids recorded originally parasitizing to M. bennettii, in this work both species are referred for the first time in association with M. cozumelae, species formerly included as subspecies of M. bennettii (
Recent studies suggest that there is no sufficient morphological evidence to maintain M. cozumelae in a specific level (
On the other hand,
