Summary: | Vibilia chuni Behning and Woltereck, 1912 (figures 10, 11) Vibilia chuni Behning and Woltereck, 1912: 8–9, figures 7, 8. Vibilia hodgsoni Stewart, 1913: 251–253, pl. 6, figures 1–6. Materials examined . See table 3. Description of female . Head length subequal to height, as long as combined length of pereonites 1–2, plus two-thirds of pereonite 3; nearly square when viewed laterally. Rostrum short, about one-eighth as long as remainder of head, and bent downward. Eyes oblong (triangular in male), well packed with ocelli, height slightly less than 1.5 times length which is about one-third (one-half in male) as long as head. Antenna 1 length equal to combined length of head and pereonite 1, flagellum length 1.8 times peduncle and 1.8 times as high. Maxilliped outer lobes slightly elongated, about three times as long as wide, strongly serrated along entire inner margin, outer margin smooth with a few fine setae. Pereon 1.3 times as long as pleon, height increasing posteriorly, pereonite 7 about 1.3 times as high as pereonite 1. Posterodistal margin of pereonites 2–7 produced posteriorly. Coxae increasing in length from pereonite 1 to 4, then decreasing to 7, ventral margin concave in coxa 5 and deeply notched in coxa 6. Pereopod 1 simple, anterior margin of basis with 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 middle of propus. Pereopod 5 about 1.2 times as long as pereopod 3, basis 1.2 times as long as ischium and merus combined, propus 0.7 times as long as merus and carpus combined and 0.9 times as long as basis. Pereopod 6 carpus, anterior margin with four spines. Pereopod 7 with complete segmentation, basis 1.3 times as long as ischium to dactyl combined, with a strongly produced posterodistal lobe reaching half way along the posterior margin of merus; carpus and propus not produced at anterodistal corner; dactyl pointed without scales. Pleon about 2.8 times as long as urosome, pleonites 1–2 subequal in length, pleonite 3 about one-tenth longer. Posterodistal corner rounded in pleonites 1 and 2 and slightly angular in pleonite 3. Urosomites 2 and 3 fused, laterodistal corners produced. Uropod 1 protopod 1.6 times as long as exopod, distal half of outer margin of protopod with large teeth, outer margin and distal half of inner margin of exopod with large teeth, both margins of endopod with large teeth. Uropod 3 protopod twice as long as wide and 1.7 times as long as exopod, inner margin of exopod and both margins of endopod finely serrated. Telson separate from double urosomite, triangular with rounded distal margin, slightly broader than long. Zeidler (1992) described and illustrated a mature male. Size . Female: 3.00– 4.20 mm; male: 3.76–5.08 mm. Distribution . Pacific Ocean: South China Sea; New Zealand. This is the first record of this species in the eastern Pacific Ocean. In the present study it was found in 31 samples from the surface to 230 m, 17°N– 18°S and 84°– 126°W (with one exception at 35°18∞N, 121°18∞W). Atlantic Ocean: 37°N– 36°S; Portugal; New York to Bermuda. : 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 280-283, DOI: 10.1080/713834685, http://zenodo.org/record/4653315 : {"references": ["BEHNING, A. and WOLTERECK, R., 1912, Achte Mitteilung uber die Hyperiden der Valdivia- Expedition, inbesondere uber die Vibiliden, Zoologischer Anzeiger, 41, 1 - 11.", "STEWART, D.
