Spurilla braziliana ( MacFarland, 1909) View in CoL View at ENA

( Figures 4E, 4F View FIGURE 4 , 5H View FIGURE 5 )

Material examined. Argentina, Río Negro: Caleta Los Hornitos, 15 specimens, intertidal, 18/12/2016 (two specimens deposited, MLP-Ma 14659); four specimens, intertidal, 03/02/2017; San Antonio Este, one specimen, intertidal, 24/08/2016 (ESCM-Ma-79); Fuerte Argentino, two specimens, intertidal, 03/03/2011 (ESCM-Ma-81); El Buque, two specimens, intertidal, 15/06/2016 (ESCM-Ma-31); Bahía San Antonio , two specimens, intertidal, 28/05/2016 (ESCM-Ma-32); Plataforma; one specimen, 12 m, 03/2017 (ESCM-Ma-80); Chubut, Puerto Lobos, one specimen (MLP-Ma 13108) .

Description. Length up to 50 mm, body elongated, orange. Rhinophores lamellate, with a white apex. Cerata arranged in 6 to 9 arches, with the tips clearer and curved towards the dorsal area of the body. Digestive glands are visible in the cerata ( Figure 4E View FIGURE 4 ). Radular formula 23 x 0.1.0. (MLP-Ma 14659). Teeth progressively smaller in the posterior region of the radula. Rachidian teeth bicurved, with between 55 to 70 denticles on each side of the central, small, and triangular cusp. ( Figure 5H View FIGURE 5 ).

Geographic distribution and depth range. Pacific and Atlantic Ocean. Hawaiian Islands, Costa Rica, Peru, Japan, China, and Australia. From Florida to Argentinean Patagonian ( Carmona et al. 2014). San Matías gulf, Argentina (Ģller & Zelaya 2017). Found in soft and intertidal bottoms under rocks up to 10 m depth.

Biology. The egg mass is a spiral white ribbon, about 30 mm in length. The egg masses are deposited on the rocks ( Figure 4F View FIGURE 4 ).

Remarks. This species has often been recorded under the name Spurilla neapolitana (Delle Chiaje 1841) . Externally, the color and morphology are not sufficient to differentiate the two species. Based on genetic data, Carmona et al. (2014) identified the southwestern Atlantic species as S. braziliana .
