            <p>Distribution and environment.</p>
            <p> This species has been found in interstitial waters in Tokyo: the sand-filter bed of the Komae Purification Plant near the Tama River (  Uéno 1955); two springs - Mamashita Spring, Kunitachi and  Hinochūōtoshokan Spring, Hino (this study). </p>
            <p>Remarks.</p>
            <p> The present specimens conform with the original description of  E. kojimai by  Uéno (1955). However, our specimens differed from the original description in the left mandible with 4-dentate lacinia mobilis and maxilla 1 with 11 serrate robust setae on the outer plate, which was 6-dentate incisor and 5-dentate lacinia mobilis of the left mandible, and 10 serrate robust setae in  Uéno’s (1955) description. The exact number of these setae is difficult to ascertain because they are minute and overlap. This suggests that he may have misstated the number of setae. Unfortunately, the type specimen of this species is believed to be lost (Tomikawa et al. 2007), so the character could not be verified. Examination of the present material from Kunitachi and Hino, Tokyo revealed some features that were not mentioned in the original description: maxilla 2 with inner plate bearing nine plumose setae in oblique row, uropod 1 peduncle with facial robust setae, and maxilliped inner plate with three subapical robust setae and medial robust seta. </p>

            <p>Remarks.</p>
            <p> Eoniphargus toriii sp. nov. is similar to  E. kojimai and  E. iwataorum sp. nov., with a head bearing deep antennal sinus, antenna 1 peduncular article 1 with a robust seta on the posterodistal corner, antenna 2 peduncular article 2 with a gland cone not exceeding peduncular article 3, uropod 1 peduncle with basofacial robust setae, and uropod 3 with 2-articulate outer ramus. However,  E. toriii sp. nov. differs from  E. kojimai and  E. iwataorum sp. nov. in the following features: right mandible with lacinia mobilis bearing three or four teeth (more than four teeth in  E. kojimai and  E. iwataorum sp. nov.) and maxilla 1 having six medial setae on the inner plate (eight medial setae in  E. kojimai and  E. iwataorum sp. nov.). </p>

Eoniphargus 
Ueno
, 1955
</p>
            <p> Neoniphargus (Eoniphargus) Uéno , 1955: 148. </p>
            <p> Eoniphargus :  Straškraba , 1964, 136, 138;  Straškraba 1967, 127; Bousfield 1977, 301; Barnard and Barnard 1983, 581-582; Holsinger 1994, 157; Tomikawa et al. 2007, 646. </p>
            <p>Diagnosis.</p>
            <p>Head without eyes, rostrum short, inferior antennal sinus distinct. Pleonites 1-3 with dorsal setae, lacking processes. Urosomite 2 with dorsal robust setae. Antenna 1 longer than antenna 2; accessory flagellum three- or four-articulate. Male antenna 2 with calceoli. Mandible with triturative molar with seta; left incisors five- or six-dentate; left lacinia mobilis four- or five-dentate; palp article 3 with A-, D- and E-setae. Maxilla 1 with inner plate bearing plumose setae; outer plate with 11 serrate robust setae. Inner plate of maxilla 2 with oblique row of facial setae. Gnathopods subchelate. Coxa of pereopod 4 with posterior concavity. Coxal gills with stalks, on gnathopod 2 and pereopods 3-6. Uropod 1 with basofacial robust setae on peduncle. Uropod 3 with small, scale-like inner ramus; outer ramus one- or two-articulate. Telson cleft with apical robust setae.</p>
            <p>Type species.</p>
            <p> Neoniphargus (Eoniphargus) kojimai Uéno , 1955, original designation. </p>
            <p>Remarks.</p>
            <p> Eoniphargus is morphologically similar to  Octopupilla in the presence of pleonites without dorsal processes, five-dentate incisor of the left mandible, mandibular palp article 3 with A-setae, inner plate of maxilla 2 with oblique row of facial setae, stalked coxal gills, peduncle of uropod 1 with basofacial robust setae, and telson lobes tapering distally. However,  Eoniphargus differs from  Octopupilla in the following features (features of  Octopupilla in parentheses): eyes absent (rudimentary eyes), incisor of right mandible five- to six-dentate (four-dentate), inner lobes of the lower lip absent (vestigial), and inner ramus of uropod 3 shorter than 0.3  × the outer ramus (0.7  × ).  Eoniphargus also resembles  Indoniphargus Straškraba , 1967, but the familial affiliation of the latter has been controversial. Tomikawa et al. (2007) and  Fišer et al. (2013) included  Indoniphargus in  Mesogammaridae . Sidorov et al. (2018) regarded  Indoniphargus as a member of  Austroniphargidae Iannilli, Krapp, &amp; Ruffo, 2011. However, since the taxonomic position of  Indoniphargus is beyond the scope of this paper, it will not be discussed here further.  Eoniphargus is distinguished from  Indoniphargus by the presence of facial setae in an oblique row of the inner plate of maxilla 2 (absent in  Indoniphargus ) and the elongate propodi of gnathopods 1 and 2 (mitten-form in  Indoniphargus ). </p>
