129. Amblyomma trimaculatum (Lucas, 1878). An Australasian and Oriental species, all of whose parasitic stages, including the undescribed larva and nymph, are usually found on Squamata: Varanidae; adults and nymphs have been collected from Squamata: Colubridae and Scincidae; and adults alone have been recovered from Squamata: Elapidae and Pythonidae (Guglielmone et al. 2014, Liyanaarachchi et al. 2015b). There are no records of Amblyomma trimaculatum causing human parasitism. M: Anastos (1950); see note below F: Lucas (1878), under the name Ixodes trimaculatus and given its current status in Horak et al. (2002) N: undescribed; see note below L: undescribed Redescriptions M: Anastos (1950), Roberts (1953, 1964 a, 1970), Kaufman (1972) and Santos Dias (1993), all under the name Aponomma trimaculatum F: Neumann (1899), Anastos (1950), Roberts (1953, 1964 a, 1970), Kaufman (1972) and Santos Dias (1993), all under the name Aponomma trimaculatum Note: Anastos (1950) claims that the description of the male of Aponomma undatum in Schulze (1933a) corresponds in fact to the male of Amblyomma trimaculatum; he also claims that Aponomma trabeatum described in Schulze (1933d) is Amblyomma trimaculatum (under Aponomma in both cases), but Aponomma trabeatum is a synonym of Amblyomma fimbriatum, as discussed in Guglielmone and Nava (2014). The description of the nymph of Amblyomma trimaculatum in Roberts (1953) probably applies to Amblyomma fimbriatum (Roberts 1970, under the genus Aponomma), and Kolonin (2009, also under the genus Aponomma) cautions that there is a lack of morphological characters useful for separating Amblyomma trimaculatum from Amblyomma fimbriatum. Indeed, none of the existing descriptions and redescriptions defines Amblyomma trimaculatum with certainty.
