From editor or global species database
Status Based on molecular mitochondrial (COI), nuclear (28S), and morphological evidence, Tetrapygus niger was recovered as the sister species to Arbacia dufresnii, both species forming a clade within the phylogeny of South American species of Arbacia. Consequently, Tetrapygus was synonymized with Arbacia by Courville et al. (2023: p. 259) and the species Tetrapygus niger reattributed to Arbacia, as previously proposed by A. Agassiz in Agassiz & Desor (1846), under the species name Arbacia nigra. [details]
