= Parapenaeon consolidata var. richardsonae Shiino, 1933

Distribution: Japan; Zhejiang, China ( Saito et al. 2000; Huang 2001).

Hosts: Metapenaeopsis acclivis (Rathbun, 1902) , M. barbata (De Haan, 1844) , Trachypenaeus anchoralis (Spence Bate, 1881) ( Saito et al. 2000; Huang 2001).

Remarks: Parapenaeon richardsonae (Nierstrasz & Brender à Brandis, 1931) was originally described in Apopenaeon Nierstrasz & Brender à Brandis, 1931 but that genus is a synonym of Parapenaeon (see Bourdon 1979). Shiino (1933) introduced the new taxon name Parapenaeon consolidata var. richardsonae which is deemed to be of subspecific rank as it was published before 1961 and Shiino (1933) expressly used the term “var.” (see ICZN Article 45.6.4). Parapenaeon consolidata richardsonae is therefore a junior secondary homonym of Parapenaeon richardsonae (Nierstrasz & Brender à Brandis, 1931) as they both are species-group names. Shiino’s (1933) taxon is still considered valid and, as such, the name needs to be replaced and we propose Parapenaeon consolidata shiinoi n. nom.

Note that one of the hosts listed by Saito et al. (2000) for this species, Penaeopsis akayebi (Rathbun, 1901) , is a synonym of Metapenaeopsis barbata (De Haan, 1844) (WoRMS 2022b) .
