Generic and specific synonymy of Mitonyssoides stercoralis Yunker, Lukoschus, and Giesen, 1990 with Coprolactistus whitakeri Radovsky and Krantz, 1998 (Acari: Mesostigmata: Macronyssidae).

Mitonyssoides stercoralis Yunker, Lukoschus, and Giesen, 1990 is recognized as a senior subjective synonym of Coprolactistus whitakeri Radovsky and Krantz, 1998, new synonymy, and therefore Mitonyssoides Yunker, Lukoschus, and Giesen, 1990 is a senior synonym of Coprolactistus Radovsky and Krantz, 1998, new synonymy. By the species synonymy reported in this work, the known range of bat guano associations for M. stercoralis is extended to include both Vespertilionidae and Molossidae. Systematic and distributional implications of the synonymies are discussed.

A new genus and species of predaceous mite in the parasitic family Macronyssidae (Acari: Mesostigmata).

Coprolactistus whitakeri Radovsky & Krantz, a new genus and species of Macronyssidae, is described in all stases. Unlike other macronyssids, all of which are vertebrate parasites, C. whitakeri is predaceous, feeding on other mites in bat guano. Its morphology confirms the family assignment, and it has the peculiar macronyssid life cycle in which a regressive, nonfeeding deutonymph follows a normal, feeding protonymph. The chelicerae are typically macronyssid despite the predatory diet. Available information indicates that C. whitakeri evolved from macronyssid parasites. C. whitakeri is a distinctive species that is not obviously close to any other described macronyssid. It occurs in the guano of the big brown bat, Eptesicus fuscus, in Indiana and in the guano of an unidentified bat in Brazil.

Ornithodoros (alectorobius) amblus (Acarina: Ixodoidea: Argasidae): identity, marine bird and human hosts, virus infections, and distribution in Peru.

Ornithodoros (Alectorobius) amblus Chamberlin 1920, adults previously were described inadequately. Practically nothing was known regarding the identity, hosts, distribution, and biology of this species. We redescribe both sexes, describe the nymph and larva, and present criteria for differentiating these stages from those of other members of the O. (A.) capensis group in the Western Hemisphere. Samples were collected from 13 localities on the Pacific coast and on offshore islands of Peru. Hosts recorded are the Peruvian Brown Pelican, Peruvian Booby, Blue-footed Booby, Red-legged Cormorant, Guanay Cormorant, and Inca Tern. These birds are not long-distance migrants and more widely distributed species of the O. (A.) capensis group have not been found parasitizing them. The life cycle is characteristic of the O. (A.) capensis group; the first nymphal instar does or does not feed. Humans are attacked eagerly by O. (A.) amblus and suffer afterward from severe inflammation and "incredible" pruritus, and possibly from more severe illness. Viruses infecting this tick are Punta Salinas (Hughes serogroup, family unclassified) and Huacho (Reoviridae, genus Orbivirus, Kemerovo serogroup). Dense tick populations cause breeding birds to desert numerous nests; thus, O. (A.) amblus is economically important to the Peruvian guano industry. Certain spiders and lizards may prey on this tick.

Macronyssid mites in oral mucosa of long-nosed bats: occurrence and associated pathology.

Macronyssid mites (Radfordiella) have been found in the oral mucosa of the long-nosed bat (Leptonycteris nivalis), which occurs from Texas southward throughout much of Mexico. This is the first report of mites of the suborder Mesostigmata attached in the oral cavity of a mammal. Osteolysis of hard palate and odontolysis of teeth result from infestations of mites adjacent to the upper premolars and molars; destruction of bone, teeth, and Connective tissue often leads to exfoliation of teeth in life. Oral mites have not been found in Leptonycteris sanborni, a species in part sympatric with Leptonycteris nivalis.
