Haemaphysalis cornigera Neumann, 1897 . Australasian: 1) Indonesia (east of Wallace’s Line); Oriental: 1) China (south), 2) Indonesia (west of Wallace’s Line), 3) Japan (the Ryukyu Islands), 4) Malaysia , 5) Myanmar , 6) Singapore , 7) Taiwan ; Palearctic: 1) Japan (except the Ryukyu Islands) ( Keirans 1985b , Durden et al. 2008 , Chen et al. 2010 , Takano et al. 2014 , Yamauchi & Hoshina 2018 , Petney et al. 2019 ). Guglielmone et al. (2014, 2020) stated that difficulties attend the morphological identification of Haemaphysalis cornigera . Some records of Haemaphysalis cornigera from Japan have been published under the name Haemaphysalis ias , a species considered valid in Guglielmone & Nava (2014) and Guglielmone et al. (2014), but Takada (1990) found that Haemaphysalis ias is in fact a synonym of Haemaphysalis cornigera . Camicas et al. (1998) excluded the Australasian Zoogeographic Region from the range of Haemaphysalis cornigera , but records from this region are treated as valid in Guglielmone et al. (2014, 2020) and here. The presence of this tick in Singapore is based on Neumann (1897) , who described the female of Haemaphysalis cornigera from a specimen collected in Singapore ; however, Kwak (2018c) did not regard this tick as present there. Zhao et al. (2021) did not list Haemaphysalis cornigera as occurring in China , but that country is included within this species´ range here. Authors such as Kolonin (2009) restricted the geographic distribution of this tick to Indonesia and Malaysia , while other authors, e.g. , Durden et al. (2008) and Petney et al. (2019) , have included India within the range of Haemaphysalis cornigera . However, Geevarghese & Mishra (2011) did not list this species as an Indian tick, a view accepted here, and the Indian records of Haemaphysalis cornigera in Tilak et al. (2017) require confirmation. Phan Trong (1977) stated that Haemaphysalis cornigera occurs in Vietnam , but its presence there was not confirmed by Kolonin (1995b) . Tanskul et al. (1983) included Haemaphysalis cornigera as a tick found in Thailand , but Tanskul & Inlao (1989) stated that their specimens were in fact Haemaphysalis shimoga .
