Laelaps is a genus of common parasitic mites in the family Laelapidae. Species, with their hosts, include:
Unnamed or unidentified species have been reported on Gerbilliscus robustus and Acomys wilsoni in Tanzania [8] and on the marsh rice rat (Oryzomys palustris) in Florida and Georgia. [12]
In 1866, an incomplete theropod dinosaur skeleton (ANSP 9995) was found in New Jersey by workers in a quarry belonging to the upper part of the New Egypt Formation. [13] Paleontologist E.D. Cope described the remains, naming the creature "Laelaps" ("storm wind", after the dog in Greek mythology that never failed to catch what it was hunting). [14] "Laelaps" became one of the first dinosaurs described from North America (following Hadrosaurus , Aublysodon and Trachodon ). Subsequently, it was discovered that the name "Laelaps" had already been given to a genus of mite, and Cope's lifelong rival O.C. Marsh changed the name in 1877 to Dryptosaurus .
Gigantolaelaps mattogrossensis is a mite from the Americas. It has been found on the marsh rice rat, hispid cotton rat, black rat, brown rat, and white-footed mouse in the United States. In Venezuela, it has been recorded from Holochilus brasiliensis, Sigmodon hirsutus, and Marmosa robinsoni. In Argentina, it has been found on Scapteromys aquaticus, Oligoryzomys flavescens, and Holochilus brasiliensis. The North American form was first described as a separate species, Gigantolaelaps cricetidarum, and is still occasionally considered as such.
Androlaelaps fahrenholzi is a species of mite in the genus Androlaelaps of the family Laelapidae. It occurs throughout the contiguous United States, where it has been recorded on the following mammals:
Eutrombicula batatas is a species of chigger.
Laelaps manguinhosi is a species of parasitic mite in the family Laelapidae. In the United States, it has been found on the marsh rice rat in Florida, Texas, and South Carolina. Other recorded hosts include the sigmodontine rodents Scapteromys aquaticus, Akodon azarae, Oligoryzomys flavescens, and Holochilus brasiliensis in Argentina and Oryzomys couesi and Handleyomys melanotis in Mexico. In Venezuela, it mainly infects the oryzomyines Holochilus sciureus and Nectomys, but it has also been recorded on a variety of other mammals and even on a bird. A separate subspecies, Laelaps manguinhosi calvescens, has been described from the ichthyomyine rodent Neusticomys venezuelae.
Listrophorus is a genus of parasitic mites in the family Listrophoridae. North American species with their hosts include:
Prolistrophorus bakeri is a parasitic mite in the genus Prolistrophorus. Together with the Argentine P. hirstianus, it forms the subgenus Beprolistrophorus. P. bakeri has been found on the hispid cotton rat, marsh rice rat, and cotton mouse in Georgia, South Carolina, Texas, and Florida and on Oryzomys couesi in Colima. It was formerly placed in the genus Listrophorus.
