Haemaphysalis colasbelcouri (Santos Dias, 1958)

This primitive Haemaphysalis possesses a number of characters similar to those of the former genus Aponomma and was originally named Aponomma colasbelcouri by Santos-Dias (1958). Hoogstraal and Wilson (1966) described Ha. vietnamensis, which proved to be a junior synonym of Ap. colasbelcouri (Camicas et al. 1998; Guglielmone et al. 2009), now correctly classified as Ha. colasbelcouri .

This is a rare species known from Vietnam and southern and southwestern China (Hoogstraal and Wilson 1966; Phan Trong 1977; Kolonin 1992, 1995; Teng and Jiang 1971). Kolonin (2009) points out that its presence in northern Vietnam is uncertain and that a closely related species might occur there. In addition, he reports that females of this species from Bamun Island (Dao Ba Mun) are intermediate between Ha. colasbelcouri (as Ha. vietnamensis) and Ha. kitaokai, a primitive Haemaphysalis species from East Asia (Hoogstraal 1969; Chen et al. 2010).

The female is described in Hoogstraal and Wilson (1966) and the male in Kolonin (1992), both as Ha. vietnamensis .
