Ixodes spinicoxalis Neumann, 1899

Ixodes spinicoxalis is an Oriental Region species that been recorded from Lao PDR and Thailand in continental Southeast Asia, as well as outlying islands (Schulze 1934; Wilson 1970; Tanskul et al. 1983), where it occurs in evergreen forests (Guglielmone et al. 2014). A single record from Caucasia (Yakimov and Kohl-Yakimova 1910) probably represents an error in identification (Anastos 1950). This species appears to be relatively rare, with few records from mainland Southeast Asia (Tanskul et al. 1983; Wilson 1970). Recent collections of over 15,000 ticks from Lao PDR did not contain this species, perhaps because wild animals were not sampled (Vongphayloth et al. 2016). Hosts include tree shrews, rodents, birds and various small carnivores (Tanskul et al. 1983; Guglielmone et al. 2014).

Nuttall and Warburton (1911) described the female, illustrating the scutum, coxae and hypostome, while Schulze (1934) described the male, illustrating the dorsum, venter, ventral capitulum, and tarsi I and IV.
