Geographic distribution. Asia : India, Myanmar, Nepal, Pakistan and Sri Lanka (our data; Sharif 1928; Kaiser & Hoogstraal 1964; Mitchell 1979; Geevarghese & Dhanda 1987; Dilrukshi 2006). Collection lot of the USNTC [RML 98964 (HH 58217), consisting of 2 males and 3 females, Burma, Pegu, Rangoon abattoir, ex domestic goat, December 1975, San-San Lin leg.] previously identified as H. hussaini , but we have reidentified them as H. brevipunctata . This is the first record of this species from Myanmar. : Published as part of Apanaskevich, Dmitry A., Horak, Ivan G. & Geevarghese, Geevarghese, 2009, The genus Hyalomma Koch, 1844. VIII.
