Haemaphysalis cinnabarina Koch, 1844a . Neotropical: 1) Brazil (Hoogstraal 1973b, Barros-Battesti et al. 2008 ). This tick is known from two specimens collected in Brazil about 175 years ago and described by Koch (1844a) ; one specimen was named Haemaphysalis sanguinolenta , a synonym of Haemaphysalis cinnabarina , as discussed in Hoogstraal (1973b). The name Haemaphysalis cinnabarina has been considered invalid by most tick workers, although some records of Haemaphysalis chordeilis have been published as Haemaphysalis cinnabarina . Hoogstraal (1973b) reinstated this tick as a Neotropical species, an opinion supported by Barros-Battesti et al. (2008) , but Keirans & Restifo (1993) and Kolonin (2009) continued to treat Haemaphysalis cinnabarina as a synonym of Haemaphysalis punctata . The position of Hoogstraal (1973b) is provisionally supported in Guglielmone et al. (2021) and here. Reyne (1932) listed Haemaphysalis cinnabarina as present in Suriname , but this diagnosis is treated as a misidentification in Guglielmone et al. (2021) and here.
