35. 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 .
