THE CORAL TRIANGLE: HEARST BIODIVERSITY EXPEDITION 
Remarks: Sternaspis piotrowskiae sp. nov. resembles S. rietschi Caiillery, 1944 from Indone¬ 
sia, found in about 1790 m depth, and recently redescribed by Sendall and Salazar-Vallejo (2013). 
However, they differ in body wall pigmentation and on the relative development of shield’s ante¬ 
rior keels; in S. piotrowskiae the body wall is whitish and anterior keels are very long, its central 
regions are often as long as the shield’s anterior margins, whereas in S. rietschi the body wall is 
brownish, and the anterior keels are veiy short. 
On the other hand, S. piotrowskiae resembles S. thorsoni Sendall and Salazar-Vallejo, 2013 
from the Arabic Sea, and found in 3-110 m depth, because both have posterior comers and a vari¬ 
able developed fan. These two species differ by the relative shape of the shield because the anteri¬ 
or keels are longer in S. piotrowskiae, surpassing the anterior margins, whereas they are shorter in 
S. thorsoni, and the fan margin is barely crenulated in S. piotrowskiae, whereas it is markedly 
crenulated in S. thorsoni. 
DiSTRffiUTiON: Philippine Islands, found in muddy bottoms, 272-636 m depth. 
Acknowledgments 
This contribution was made possible by the kind support of Christina Piotrowski, Collections 
Manager of Invertebrate Zoology, CAS, and by Leslie Harris and David Ocker that due to their 
unconditional and typical hospitality, provided a home during a part of my sabbatical leave. Funds 
for this work were given by ECOSUR, and CONACYT (sabbatical leave scholarship, 176535).
