Short Description
Diagnose after GABBANELLI, DE ASTARLOA, GONZALEZ-CASTRO, VAZQUEZ & MABRAGANA, 2018 [26826]: Zearaja brevicaudata is a relatively large species of skate with a rhombic-shaped disc characterized by the combi-nation of the following characters: relatively large snout (1.7–2.9 times tail length), short tail (2.1–2.7 times in total length), and short distance between the first gill openings (3.42–4.19 times indirect disc length). Even though these relationships overlap with those of Z. chilensis, these features differ diagnostically among specimens of similar size (Fig. 7). The dermal denticles are mainly restricted to the rostral area, both in dorsal and ventral surfaces. Denticles are more conspicuous in adults, and can be absent or in less number in neonates and juveniles. Three to five rows of thorns are present on the tail (rarely only one). The clasper is relatively long and stout, 74–78% of the tail’s length in adult specimens. The terminal bridge (Tb) is straight towards the tip of dorsal terminal 2, and the spike is thin and does not reach the Tb. The ventral terminal cartilage has a short apophysis, and its outer edge is narrow. The distal tip of the axial is relatively narrow.
