Similar Species

Plectranthias lasti differs from the similar P. megalophthalmus in having 15 vs. 14 soft dorsal-fin rays, a deeper body (depth 3.05 in SL, vs. 3.4 for P. megalophthalmus), and a smaller eye (4.0 in head vs. 2.9 for P. megalophthalmus). 


This species is named lasti in honour of Peter R. Last who collected the paratype, recognised it as undescribed, and made the CSIRO specimen available to the authors.
