First coxal plates separated medially. Suture line of second and third coxal plates and suture line of third and fourth coxal incomplete. Medial posterior apodemes of fourth coxal plates long, lateral apodemes short. Between these two apodemes a pair of glandularium­like structures, separated from accompanying setae. Genital field located between medial posterior apodemes. Genital field 56 long and 42 wide, pregenital sclerite and postgenital sclerite strongly bowed and almost touching each other.

Genital field located between medial posterior apodemes. Genital field 28 long and 25 wide, sclerotized ring around gonopore with four pairs of setae. Around genital field relatively few (approximately 20) short setae. Posteriorly of genital field two pairs of wheel­like acetabula. Lengths of PI­PV: 15, 76, 26, 86, 30; palp as in female. Lengths of I­leg­4­6: 50, 70, 66. Lengths of IV­leg­4­6: 95, 114, 102. IV­leg­ 5 with two swimming setae.</p><p>Remarks</p><p>The new species is remarkably similar to the Mediterranean L. duboscqi in the shape of the palp and coxal plates. Differences can be found in the glandularium­like structure posteriorly of the fourth coxal plates, which is fused with the accompanying setae in duboscqi, and separated in the new species. Moreover, the anterior pair of wheel­like acetabula is much more separated in the new species. The palps of the two species are similar. In the holotype the setal tubercle appears smaller compared to L. duboscqi, but paratypes (fig. 8) have PIV similar to that of duboscqi .</p></div>	https://treatment.plazi.org/id/03A687FFFF8A5B65FEAFFBC7B527FE09	Public Domain	No known copyright restrictions apply.

In his description he pointed on the similarity of this species with P. anellata Sokolov, known from the Sea of Ochotsk (Russian Pacific coast). According to Imamura (1958) differences between the two species can be found in the shape of the posterior apodemes of the fourth coxal plates and in the relatively longer PIV of P. hinumaensis . When comparing the illustrations of both species, they show a striking similarity in the shape and configurations of the wheel­like acetabula: the wheel­like acetabula are very large, a characteristic not found in other Pontarachna species. The length of PIV of the two species is almost the same. Pontarachna anellata is only known from the female sex, and P. hinumaensis only known from the male sex. Within the genus Pontarachna sexual dimorphism can be found in the shape of the posterior apodemes of the fourth coxal plates, as can be seen in the illustrations of P. pacifica by Uchida (1935). The female of P. pacifica has longer apodemes compared to the male, and this is also found in anellata and hinumaensis . The only difference between the two species is the complete suture line of the second and third coxal plates in hinumaensis, but as this is only found on one side, it must be considered more as an anomaly than as a character of this species. Therefore, I consider P. h i n u m a e n s i s a junior synonym of P. anellata .</p></div>	https://treatment.plazi.org/id/03A687FFFF8C5B66FEAFFA02B471FD91	Public Domain	No known copyright restrictions apply.
