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]
