Notes

Biology: The hosts and biology of A. macarthorum was previously unknown. This species breeds in small branches ( 2–4 cm in diameter) of C. inermis (newly-recorded host). Eggs were deposited in 2–3 clusters per gallery, each cluster contained 4– 6 eggs. Developmental stages of progeny varied amongst individuals within each gallery. A total of 12–26 progeny were recorded per gallery (n = 5), with a strongly female-biased sex ratio of 16: 1 (n = 2).
