Hyalomma isaaci Sharif, 1928

In India, Hy. isaaci is found in a variety of climate zones. The species was recorded in Vietnam as Hy. marginatum indosinense (Kolonin 1995) . Toumanoff (1944) was the first to find this Hyalomma in Southeast Asia, where he reported 4 males on a banteng ( Bos sondaicus) in Vietnam (identified as Hy. dromedarii indosinensis). The next collection was made in 1992 by Kolonin (2 males and 1 female) from the same host and also in Vietnam. A male/ female pair of specimens was reported on clothing in Myanmar (Robbins et al. 2002).

Descriptions of all active life history stages, together with illustrations of the male and female and line drawings of the nymphal and larval capitula, scuta and coxae, are available in Geevarghese & Dhanda (1987).
