Spinturnix is a genus of mites in the family Spinturnicidae. [2] Spinturnix mites are an ectoparasite found on species of bats. They live exclusively on the wing and tail membranes and are large enough to be seen with the naked eye. Spinturnix mites are a host specific species, meaning they have a few major host species that they prefer, as well as a few less frequently used hosts. [3] In short, these mites will not infect arbitrary bat species. Their selection of host tends to align with the host species that lives closest to their local environment. Spinturnix mites are found strictly on Microchiroptera. [4] These mites are hematophagous, meaning they feed on the blood of their host. They cannot survive without a host for more than a few hours. [5] Therefore, transmission of mites to other hosts must occur by close contact, such as a bat in a roost. [6]
Spinturnix mites are crab-like in appearance. Males have a shield-shaped plate on their underside and a pointed abdomen, while females have teardrop shaped shields and a rounded abdomen. [7] The adaptive claws of the mite allows it to grip the wing membrane and efficiently keep hold of their host, even when their host is in flight. [8]
Spinturnix reproduce sexually, but have been shown to align their reproductive cycle on that of its host, specifically by infesting newborns, which are a vulnerable host.
In Spinturnix mites, the egg and larva are embryonated and thus an active protonymph is born. The deuteronymph, which is the second stage of the life cycle, actively parasitizes and is similar to an adult mite in size and appearance. [9] It has been demonstrated that Spinturnix mites end their reproduction and metamorphosis in winter, when their host species go into hibernation cycles. The life cycle of these mites is extremely shortened, which contributes to the instinct to preserve the offspring. Spinturnix mites spend their entire life cycle on the host species. [10]
Spinturnix mites can be found globally. They have been seen on bat species from North America to Asia to Europe to Africa. [11]
Studies have shown that Spinturnix mites are more prevalent on female hosts than male hosts. There is a higher survival rate for the mites when on a female host. However, Spinturnix mites also show preference towards subadult male hosts. Young host bats that are still dependent on their mother also show a high infestation rate. These preferences demonstrate the Spinturnix mite's ability to detect the host that they find to be the most beneficial to their survival. [12]
Spinturnix mites have a strong influence on the health and fitness of their host species of bats. These mites have the strongest impact during the maternity period of bat species. It has been demonstrated that pregnant or lactating bats have experienced increased oxygen consumption and weight loss due to Spinturnix infestations. [13] Due to their hematophagous nature, these mites can cause anemia, lethargy, and loss of appetite in bats as well. [14]
These 51 species belong to the genus Spinturnix: [15] [16]
The Streblidae are a family of flies in the superfamily Hippoboscoidea, and together with their relatives the Nycteribiidae, are known as bat flies. They are winged or wingless ectoparasites of bats, and often have long legs. They appear to be host-specific, with different species of bat flies occurring only on particular species of bat hosts, sometimes with multiple species of flies sharing a host bat.
Nycteribiidae is a family of the true fly superfamily Hippoboscoidea are known as "bat flies", together with their close relatives the Streblidae. As the latter do not seem to be a monophyletic group, it is conceivable that bat flies cannot be united into a single family.
The black myotis is a vesper bat species from South and Central America.
The buffy flower bat is a species of bat in the leaf-nosed bat family, Phyllostomidae. It is found in the Bahamas, the Cayman Islands, Cuba, and Jamaica.
The little brown bat or little brown myotis is an endangered species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus.
The Laelapidae are a family of mites in the order Mesostigmata. The family is also referred to in the literature as Laelaptidae, which may be the correct spelling.
Dermanyssoidea is a superfamily of mites, including most of the mites which parasitise vertebrates.
Laelaps is a genus of common parasitic mites in the family Laelapidae. Species, with their hosts, include:
Spinturnicidae is a family of mites in the order Mesostigmata. The mites are highly specialized parasites of wing or tail membrane or bats. Some species infest eyelids and eye canthi. The species of Spinturnicidae are found in bat habitats throughout the world, living all stages of life on bats.
Ancystropus is a genus of mites in the family Spinturnicidae. There are about seven described species in Ancystropus, found in Asia, the Middle East, Africa, and South Pacific islands.
Eyndhovenia is a genus of mites in the family Spinturnicidae. There are at least two described species in Eyndhovenia.
Meristaspis is a genus of mites in the family Spinturnicidae. There are about six described species in Meristaspis, found in Asia, Africa, the Middle East, Australia, and the Pacific islands.
Mesoperiglischrus is a genus of mites in the family Spinturnicidae. There are at least two described species in Mesoperiglischrus, found in the Neotropics.
Paraperiglischrus is a genus of mites in the family Spinturnicidae. There are at least four described species in Paraperiglischrus, found in Asia, Europe, Africa, Australia, and the Pacific Islands.
Periglischrus is a genus of mites in the family Spinturnicidae. There are more than 30 described species in Periglischrus, found in South, Central, and North America, and in Africa.
Polychromophilus is a genus of obligate intracellular eukaryotic parasites that infect bats from every continent except Antarctica. They are transmitted by bat flies, which act as an insect vector as well as the parasite’s site of sporogeny. Polychromophilus follows a fairly typical Haemospororidian lifecycle, with gametocytes and gametes restricted to the bloodstream of the host and meronts infecting organs – most notably the lungs and the liver. The type species is Polychromophilus melanipherus, and was described by Dionisi in 1898.
The Alcathoe bat is a European bat in the genus Myotis. Known only from Greece and Hungary when it was first described in 2001, its known distribution has since expanded as far as Portugal, England, Sweden, and Russia. It is similar to the whiskered bat and other species and is difficult to distinguish from them. However, its brown fur is distinctive and it is clearly different in characters of its karyotype and DNA sequences. It is most closely related to Myotis hyrcanicus from Iran, but otherwise has no close relatives.
Hematophagy is the practice by certain animals of feeding on blood. Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without great effort, hematophagy is a preferred form of feeding for many small animals, such as worms and arthropods. Some intestinal nematodes, such as Ancylostomatids, feed on blood extracted from the capillaries of the gut, and about 75 percent of all species of leeches are hematophagous. The spider Evarcha culicivora feeds indirectly on vertebrate blood by specializing on blood-filled female mosquitoes as their preferred prey. Some fish, such as lampreys and candirus; mammals, especially vampire bats; and birds, including the vampire finch, Hood mockingbird, Tristan thrush, and oxpeckers, also practise hematophagy.
Spinturnix americana is a species of mite that parasitizes bat wings. It was described as a new species in 1902 by American entomologist Nathan Banks. Banks initially placed it in the now-defunct genus Pteroptus. The holotype had been collected from a bat in a cave in Indiana. Species that it affects include the little brown bat, northern long-eared bat, and riparian myotis. It has been documented affecting bats in Indiana and Pennsylvania in the United States, Nova Scotia in Canada, and Mato Grosso in Brazil.
Leptotrombidium myotis is a species of mites in the family Trombiculidae that parasitizes bats. Species that it affects include the Arizona myotis, little brown bat, and northern long-eared bat.
