Redescription of Two Krithid Species (Crustacea, Ostracoda) from the Sea of Japan, with a Comment on the Taxonomic Characters of Krithidae

The marine podocopid ostracod Krithe antisawanensis is redescribed on the basis of its appendages and the carapaces of adult male and female specimens. The krithid species Parakrithella pseudadonta, which has only been previously described on the basis of the carapace morphology and male appendages excluding the copulatory organ, is redescribed here with its female appendages and male copulatory organ. Both krithid genera (Krithe and Parakrithella) have three articulated podomeres in the fifth and sixth limbs and an axe-head anterior vestibulum. Such characters are useful as diagnostic features for the family.
