South African tortoise tick

Member of the A. marmoreum complex; expert morphological or molecular confirmation must distinguish related species.

Field cycle may complete in one or two years depending on nymphal feeding timing; laboratory host and climate conditions alter timings.

Laboratory comparisons used tortoises and guinea pigs at 25°C and 85% RH; results are not universal field measurements.

Larvae active in late summer/autumn; nymphs near tortoise home areas active in early spring; adults active in summer in the Eastern Cape study.

Eastern Cape ecological field evidence; it must not be generalized to the entire species range.
