Vibilia pyripes Bovallius, 1887 (figures 1, 2) Vibilia pyripes Bovallius, 1887a: 10; 1887b: 71, pl. 10, figures 23–30. Vibilia hirondellei Chevreux, 1900: 126–129, pl. 15, figure 4. Vibilia grandicornis Chevreux, 1900: 131–134, pl. 16, figure 2. Materials examined . See table 3. Description of female . Head length three-quarters height, about 0.6 times as long as pereonites 1 and 2 combined, nearly rectangular when viewed laterally. Rostrum about one-sixth as long as remainder of head and slightly bent downward. Eyes oblong (pear-shaped in male), well packed with ocelli, height about 1.6 times length which is slightly less than one-half (about two-thirds in male) as long as the head. Antenna 1 length equal to combined length of head, pereonite 1 and two-thirds of pereonite 2, flagellum twice as long as peduncle, 1.7 times as long as high. Maxilliped outer lobes narrow, more than three times as long as wide, with a few strong teeth on the proximal two-thirds of inner margin, outer margin smooth with a few fine setae. Pereon 1.4 times as long as pleon, height increasing posteriorly, pereonite 7 about 1.5 times as high as pereonite 1. Posterodistal margin of pereonites 3–7 bent posteriorly. Coxae increasing in length and height from pereonite 1 to 4, then decreasing to 7; ventral margin of coxae 5 and 6 with a notch in mid-length. Pereopod 1 simple, anterior margin of basis with a slight bulge at proximal third, propus with posterior margin finely serrated and distal margin as wide as dactyl. Pereopod 2 subchelate, carpal process reaching to one-third of propus. Pereopod 5 about 1.5 times as long as pereopod 3, basis slightly longer than ischium and merus combined, propus three-quarters as long as merus and carpus combined and slightly longer than basis. Pereopod 6 carpus, anterior margin with fine dentition and three large spines, the spines with finely branched margins distally. Pereopod 7 with complete segmentation, basis 0.6 times as long as ischium to dactyl combined, posterodistal corner with a strong protrusion reaching mid-length of merus; carpus and propus not produced at anterodistal corner; dactyl finely scaled on distal half of posterior surface. Pleon about 2.6 times as long as urosome, pleonites 1–3 subequal in length. Posterodistal corner of pleonites 1 and 2 rounded, of pleonite 3 angular. Urosomites 2 and 3 fused, laterodistal corners slightly produced. Uropod 1 protopod 1.6 times as long as exopod. Uropod 3 protopod broad, as long as wide, distally widening, as long as endopod. Telson separate from double urosomite, rounded, slightly broader than long. Size . Female: 4.80–8.72 mm; male: 2.80–7.00 mm. Distribution . Pacific Ocean: Japan; South China Sea; New Zealand. This is the first record of this species for the eastern Pacific Ocean. In the present study, this species occurred in 17 samples, mostly shallower than 250 m, with an exception at 1253– 1207 m and has a relatively wide distributional range from 20°S to 33°N and 119°W eastward to the continents of the Americas. Atlantic Ocean: 51°N– 43°S; Newfoundland; Azores. Indian Ocean: Gulf of Oman; Arabian Sea; near Equator. : Published as part of SHIH, CHANG-TAI & HENDRYCKS, ED A., 2003, A new species and new records of the genus Vibilia Milne Edwards, 1830 (Amphipoda: Hyperiidea: Vibiliidae) occurring in the eastern Pacific Ocean, pp. 253-296 in Journal of Natural History 37 (3) on pages 270-272, DOI: 10.1080/713834685, http://zenodo.org/record/4653315 : {"references": ["BOVALLIUS, C., 1887 a, Systematic list of the Amphipoda Hyperiidea, Bihang till Kongliga Svenska Vetenskaps-Akademiens Handlingar, 11 (16), 1 - 50.", "BOVALLIUS, C., 1887 b, Contribution to a monograph of the Amphipoda Hyperiidea, Part I: 1.
