Ecology and parasitism
Nosomma monstrosum is an obligate ectoparasite of mammals, particularly Asian water buffaloes. Adults are also known from cattle, pigs, dogs, bears and horses. Instars - larvae and nymphs - are mostly known to parasitise rodents and shrews.[2] The species is distributed across south and south-eastern Asia, being found in Thailand, India, Nepal, Sri Lanka, Laos, Bangladesh, Vietnam, Pakistan, Myanmar and Tibet.[3]
Nosomma monstrosum is a likely three-host tick, although adverse environmental conditions may alter this behaviour.[4] While the species is found in the Kyasanur Forest disease endemic area, it is not known to be a vector.[5] Nosomma ticks are very rare parasites of humans, and no pathogenesis has been described.[6]

Taxonomy
Nosomma was first described by Schulze as a monotypic genus for the species Hyalomma monstrosum.[7] The genus is closely related to Dermacentor and Hyalomma.[3] Prakasan & Ramami described a new species, Nosomma keralensis, in 2007,[8] but the species has been subsequently rejected due to its poor description and unsuitable differentiating characters.[2][3]
