Amenia nigromaculata has a largely coastal distribution in southwestern Australia, ranging from Exmouth Gulf in the north and extending eastwards along the Great Australian Bight to Yalata in South Australia [2]. The species is associated with host snails of the genus Bothriembryon (Orthalicidae), specifically B. balteolus, B. bulla, and B. glauerti [2]. Phylogenetic evidence suggests that A. nigromaculata is the sister species of Amenia chrysame [2].
Based on observations from the TreeOfLife-200M dataset, Amenia nigromaculata exhibits the characteristic metallic, often iridescent, coloration typical of the genus Amenia [1]. The abdomen displays distinct dark, often black, markings or spots against a metallic background, which contribute to its specific appearance [1].
