【 摘 要 】

Pellonyssus nidicolus Baker, Delfinado, and Abbatiello, 1976 es un nuevo sinónimo de Pellonyssus reedi (Zumpt y Patterson, 1952). La sinonimia de Pellonyssus passeri Clark y Yunker, 1956 con P. reedi se mantiene. Los ejemplares de Pellonyssus reportados por Estébanes-González (1997) son identificados aquí como pertenecientes en parte a P. reedi y en parte a P. marui Yunker y Radovsky, 1966, es el primer reporte de estas especies en México. La tercera especie identificada de Pellonyssus conocida en el Nuevo Mundo es un parásito de colibrís Pellonyssus gorgasi Yunker y Radovsky, 1966, previamente reportado de México. Las claves para identificación de hembras, machos y protoninfas de estas 3 especies se incluyen. Un carácter común se da para comparar rasgos distintivos de las hembras de 9 especies validas de Pellonysssus en el mundo. La subespecie Ornithonyssus sylviarum utrechtensis Micherdzinski, 1980 es sinonimizada con la subespecie nominal O. s. sylviarum (Canestrini y Fanzago, 1877). Palabras clave: Pellonysus, Ornithonyssus, Macronyssidae, pájaros silvestres, México, Nuevo Mundo, ácaros, parásitos.   ABTRACT Pellonyssus nidicolus Baker, Delfinado, and Abbatiello, 1976 is relegated to the status of a junior synonym of Pellonyssus reedi (Zumpt and Patterson, 1952). The synonymy of Pellonyssus passeri Clark and Yunker, 1956 with P. reedi is sustained. The Pellonyssus specimens reported by Estébanes-González (1997) are identified here as belonging in part to P. reedi and in part to P. marui Yunker and Radovsky, 1966, the first records of these species in Mexico. The third identified species of Pellonyssus known in the New World is a parasite of hummingbirds, Pellonyssus gorgasi Yunker and Radovsky, 1966, previously reported from Mexico. Keys to identify the females, males, and protonymphs of these 3 species are given. A character grid is given to compare features of females of the 9 valid species of Pellonyssus in the world. The subspecies Ornithonyssus sylviarum utrechtensis Micherdzinski, 1980 is synonymized with the nominal subspecies O. s. sylviarum (Canestrini and Fanzago, 1877). Key Words: Pellonyssus, Ornithonyssus, Macronyssidae, wild birds, Mexico, New World, mites, parasites.   INTRODUCTION Estébanes-González (1997), in reporting on mites that she found in the nests of wild birds in Mexico, identified the Pellonyssus specimens that were collected as P. nidicolus Baker, Delfinado, and Abbatiello, 1976. Radovsky (1998), in reviewing the known species of Pellonyssus, overlooked P. nidicolus. Further study of the material identified by Estébanes-González (1997) shows that it comprises 2 Pellonyssus species. Because of our uncertainty about the validity of P. nidicolus, we examined the relevant type material. In this paper, we establish the new synonymy of P. nidicolus under P. reedi (Zumpt and Patterson, 1952), comment on other reported synonymies relating to P. reedi, provide further information for the separation of Pellonyssus species, and reassign collections of Pellonyssus reported by Estébanes-González (1997) to P. reedi and Pellonyssus marui Yunker and Radovsky, 1966, both species reported from Mexico for the first time. We also synonymize Ornithonyssus sylviarum utrechtensis Micherdzinski, 1980 under the nominal subspecies and include the specimens identified by Estébanes-González (1997) as O. s. utrechtensis in O. s. sylviarum.   MATERIALS AND ME
