Comparison with the type material of R. spinicincta has revealed that the new species is easily distinguished from R. spinicincta by the following characters: (1) lateral teeth on the rostrum are present in R. ohtsukai, whereas they are entirely absent in R. spinicincta; (2) the length ratio of cornea and eyestalk is 1: 0.7 in R. ohtsukai, whereas it is 1: 2.7 in R. spinicincta; (3) the eyestalk has relatively reduced armament in R. ohtsukai, but it is armed with many large spines in R. spinicincta; (4) the propodi and carpi of the fourth and fifth pereopods are subdivided into 8–15 and 10–12 articles, respectively, in R. ohtsukai, rather than into the 4 and 5 articles in R. spinicincta (cf. Kemp 1910; Forest &amp; Holthuis 1997).</p></div>	https://treatment.plazi.org/id/03EB87A17E173A490FE8FB99FC1E13BA	Public Domain	No known copyright restrictions apply.

The specific name is derived from the Latin, parvus (=small) and oculus (=eyed), in reference to the relatively small eye of this new species.</p><p>Distribution. So far known only from off Tosa Bay, western Japan.</p><p>Ecological notes. The present specimens were collected from the gastric cavity of hexactinellid sponges.</p><p>Remarks. Although the female specimen lacks the third pereopods, the assignment of the new species to Richardina is justified by the presence of uniunguiculate dactyli on the fourth and fifth pereopods and the lack of any spines on pleonal somites. The new species is described only from a single damaged female and a single male specimen. Assessment of diagnostic characteristics of this species will be made more precisely when more specimens become available. Richardina parvioculata n. sp. appears unique within the genus in lacking the median row of spines on the posterior margin of the cervical groove, having the large eyestalk and contrasting small-sized cornea, as well as the blunt spines on the dorsolateral carinae of the telson. The new species is most similar to the Mediterranean species R. fredericii, in the general armature of the carapace and pleonal somites, the number of cinctures of spines on the posterior margin of the cervical groove, and the number of articles of the propodi and carpi of the fourth and fifth pereopods. But the new species is easily distinguished from R. fredericii by the following characteristics: (1) the lateral teeth on the rostrum are absent in R. parvioculata, whereas there are 1–3 in R. fredericii; (2) the length ratio of cornea and eyestalk is 1: 2.8 in R. parvioculata, against 1: 1.9 in R. fredericii; (3) the length ratio of dactyli, propodi, carpi, meri, ischia of fourth and fifth pereopods is 1: 2: 3: 2.3: 1.5 in R. parvioculata, against the relatively longer 1: 4: 6.6: 5.2: 2.5 in R. fredericii (cf. Lo Bianco 1903; MacPherson 1978).</p></div>	https://treatment.plazi.org/id/03EB87A17E1F3A4D0FE8FDF5FCC41588	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
