Three new species of Poecillastra are described here from bathyal waters off central Chile. P. antonbruunae n. sp. is diagnosed by its two categories of oxeas, the smaller one only up to 621 μm in length, and calthrops as the sole triaene category; P. sinetridens n. sp. by the possession of oxeas larger than 3000 μm long, microxeas which can be over 300 μm long, and absence of triaenes; and P. maremontana n. sp. by its three categories of oxeas, three categories of streptasters (one of spirasters and two of plesiasters), one category of calthrops and centrotylote microxeas. Comments upon other Poecillastra and an identification key for Pacific species of the genus are given. Evolutionary hypotheses are discussed for the genus given the di...
