Nosomma

thumb|Nosomma monstrosum is known best from the Water buffalo|Asian water buffalo. Nosomma monstrosum is a species of hard-bodied tick found in Asia. The species is found primarily on water buffalo. It is the only member of the monotypic genus Nosomma. ==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. 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.

Nosomma monstrosum is a likely three-host tick, although adverse environmental conditions may alter this behaviour. While the species is found in the Kyasanur Forest disease endemic area, it is not known to be a vector. Nosomma ticks are very rare parasites of humans, and no pathogenesis has been described.
