Two new species of Apseudomorpha (Peracarida: Tanaidacea) from the East China Sea, with a key to the species of Phoxokalliapseudes

Abstract

Two new species of Wandogarida Wi & Kang, 2018 and Phoxokalliapseudes Drumm & Heard, 2011 are described from the East China Sea. Wandogarida sentaeminentia n. sp. is the second species to the genus Wandogarida known and can be distinguished from the type species, W. canalicula Wi & Kang, 2018, by a peculiar pleonal hyposphenium having a rugose surface and a maxillule with a biarticulate palp. The key morphological characters and the sexual dimorphism of Wandogarida were redefined after a comparison of its two species. Phoxokalliapseudes gibbus n. sp. can be differentiated from its congeners by an antennular article 1 having a robust spiniform seta and a pleopod exopodite having a process with setules. A key to the seven species of Phoxokalliapseudes is provided, together with a discussion of the diversity and distribution of the tanaidaceans of the East China Sea.
