Nosomma monstrosum ( Nuttall and Warburton, 1908)

Nosomma monstrosum is an unusual species which was originally classified, with reservations, as a Hyalomma , although it also shows certain characteristics of the genus Dermacentor ( Nuttall and Warburton 1908; Warburton 1918). It does not possess the elongate mouthparts and beady eyes of Hyalomma but does possess enamelling and male ventral shields ( Schulze 1920). Adult N. monstrosum are most commonly found on buffalo, although they have also been recorded from cattle, horses, pigs and dogs (Hoogstraal 1985b; Petney and Keirans 1996b). Immatures occur mainly on rodents. This species is found in Lao PDR, Myanmar, Thailand, and Vietnam ( Toumanoff 1944; Tanskul et al. 1983; Hoogstraal 1985b; Kolonin 1992, 2009), as well as India, Nepal, Sri Lanka and Bangladesh ( Kolonin 2009). The life cycle has been determined for a Sri Lankan population of this species ( Bandaranayaka et al. 2016).

Descriptions of adults are found in Arthur and Chaudhuri (1965) and immatures in Singh (1968).
