Acanthemblemaria aceroi new species is described from the upwelling region of the Caribbean coasts of Venezuela and Colombia. It differs from its closest relative, Acanthemblemaria rivasi Stephens, 1970, known from Panama and Costa Rica, in the posterior extent of the infraorbitals, details of head spination, and unique COI sequences. The description of Acanthemblemaria johnsonsi Almany Baldwin, 1996, heretofore known only from Tobago, is expanded based on specimens from islands offshore of eastern Venezuela.
阿塞罗氏棘雀鲷新物种是在委内瑞拉和哥伦比亚加勒比海岸的上升流区域发现并被描述的。它与其亲缘关系最近的物种——1970年在巴拿马和哥斯达黎加发现的里瓦西氏棘雀鲷在眶下骨的后部范围、头部棘刺细节以及独特的细胞色素氧化酶亚基I（COI）序列方面存在差异。此前仅在多巴哥发现过的1996年的约翰逊氏棘雀鲷，根据委内瑞拉东部近海岛屿的标本，对其描述进行了扩充。
