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.
