          Abstract

          Resumen:Los ácaros se relacionan con pasálidos, estableciendo una asociación temporal para transportarse (foresia). Se conocen más de 200 especies de ácaros forontes de pasálidos. El objetivo del estudio fue conocer la diversidad de ácaros asociados a dos especies de Odontotaenius,así como determinar sus sitios de fijación. Se recolectaron pasálidos de troncos en descomposición en seis estados de México. Se encontraron 80 pasálidos con ácaros (64 de O. zodiacusy 16 de O. striatopunctatus),en total 1 945 ácaros de 13 familias, distribuidos en 42 especies. En O. striatopunctatusse encontraron 562 ácaros (95 \[, 34 c?c?, 197 H, 234 D, 2 T) de 22 especies; mientras que para O. zodiacus,1 383 organismos (300 ??, 204 608 H 139 D, 133 T) de 30 especies. La mayoría se encontraron en las coxas, bajo los élitros y las alas membranosas desarrollando foresia pasiva. La efectividad del muestreo fue mayor en O. zodiacus,lo que se refleja en los índices de diversidad y similitud. El índice de Shannon-Wiener, muestra una mayor diversidad en O. zodiacus(H'= 2.2) que en O. striatopunctatus(H'= 1.94). Odontotaeniuses el género que tiene más especies de ácaros asociados y se registran por vez primera 12 especies: Abrotarsala cuneiformis, A. obesa, A. pyriformis, Brachytremellasp., Diarthrophallus cartwrighti, D. crinatus, Lombardiniellasp., Trichodiplogynium carlosi, T. sahlbergi, T. hirsutumy Trichodiplogyniumsp.

          Abstract:Mites can establish association with different arthropods as coleopterans families Scarabaeidae and Passalidae. Passalids are distributed in tropical and templates zones, and until now, more than 200 species of mites have been associated to them. One of the relationships between passalids and mites is the phoresy where one small animal (the phoretic) seeks out and attaches to another animal (the host) for transportation. Herein, we studied the mites associated to O. zodiacusand O. striatopunctatus;for this, 80 Odontotaeniuswith mites were reviewed; passalids were collected in and under decaying logs from six states of Mexico, and were individually kept in vials with 80% ethanol. The specimens were carried to the laboratory and mites removed with fine-pointed forceps under stereo microscope. The mites were stored with 80 % alcohol until some were cleared with lacto-phenol and mounted in Hoyer's solution. We found 1 945 mites belonging to 13 families (Acaridae, Ascidae, Diarthrophallidae, Digamasellidae, Diplogyniidae, Euzerconidae, Heterocheylidae, Histiostomatidae, Klinckowstroemiidae, Laelapidae, Megisthanidae, Trematuridae, and Uropodidae) and 42 species, being the most abundant species Anoetussp. For O. striatopunctatus(16 specimens) we found 562 mites (95 \], 34 c?c?, 197 hypopus, 234 deutonymph, 2 tritonymph) of 11 families and 22 species; the most abundant were Uropodidae (42 %) and Histiostomatidae (26 %). While for O. zodiacus(64 specimens) were found 1 383 mites (300 $$, 204 c?c?, 608 hypopus, 139 deutonymphs, 133 tritonymphs) of 10 families and 30 species; the most abundant were: Diartrophallidae, Acaridae, and Histiostomatidae (23 % for the two first and 21 % for third). The high abundance and richness was in O. zodiacus,likewise Margalef (S') and Shanon-Winner (H') indexes were higher in this species (O. zodiacusS' = 4.05, H' = 2.2; O striatopunctatusS' = 3.34, H' = 1.94), while Equity (EH) was similar to both hosts (O. zodiacusEH = 0.64; O. striatopunctatusEH = 0.63). The mites were found principally in the protected zone of the passalid's body, as under elytron, membranous wings, and in the clefts of the ventral region of the passalid, and, in minor proportion, on the head and coxal regions. From our findings, 12 species were new records for the Mexican passalids: Abrotarsala cuneiformis, A. obesa, A. pyriformis, Brachytremellasp., Diarthrophallus cartwrighti, D. crinatus, Lombardiniellasp., Trichodiplogynium carlosi, T. sahlbergi, T. hirsutumand Trichodiplogyniumsp., and additional studies may help describe and understand these mites-passalids associations.
