Plesionika polyacanthomerus - Paulmier, 1993: 19, Guadeloupe, Martinique [Trap, 200-580 m]. - Paulmier & Gervain, 1994: 10, tab. 2, Martinique [R/V Polka, deep trap]. - Gervain et al., 2002: 32, Guadeloupe [R/V Polka, trap 530 m]. - All not P. polyacanthomerus Pequegnat, 1970 (cf. re-det. A. Crosnier, in Poupin, 1994, IRD Etudes & Thèses, p. 26).
Plesionika macropoda - Monterrosa, 1988: 637, St Thomas, St Croix. - Poupin, 1994: 25, Guadeloupe [R/V Polka, 310-500 m; and re-det by A. Crosnier of previous records as P. polyacanthomerus from same collections in Paulmier (1993) and Paulmier & Gervain (1994)].
Comment: this species is affiliated to Plesionika williamsi Forest, 1964. It is interesting to notate that Forest (1964) when describing P. williamsi has not considered P. macropoda. Therefore the two species could be co-specific. However, A. Crosnier (in Poupin, 1994: 26) indicates that the two species can be separated by third abdominal tergite more or less spinous in P. williamsi, rounded in P. macropoda.
Plesionika macropoda has been confused with Plesionika polyacanthomerus Pequegnat in Paulmier (1993) and Paulmier & Gervain (1994). The two can be separated by 'a broad curved ridge on the lateral face of the carapace, in P. polyacanthomerus, absent in P. macropoda, and by more spines on P3 merus in P. polyacanthomerus (20-34) than in P. macropoda (9-10 in Monterrosa, 1998, fig. 4).
