Onchocalanus hirtipes Sars, 1905 (F,M) | |
| | | | | | Syn.: | no Onchocalanus hirtipes : A. Scott, 1909 (p.83, figs.F) | | | Ref.: | | | Sars, 1905 b (p.20, Rem.F); Farran, 1908 b (p.49, Rem.); With, 1915 (p.231, figs.F,M); Sars, 1925 (p.148, figs.F); Rose, 1933 a (p.138, figs.F); Vervoort, 1950 a (p.33, Rem.); Park, 1983 a (p.351, figs.F, Rem.); Tanaka & Omori, 1992 (p.265, figs.F); Chihara & Murano, 1997 (p.854, Pl.140: F); Vives & Shmeleva, 2007 (p.693, figs.F,M, Rem.) | issued from : T. Park in Antarct. Res. Ser. Washington, 1983, 39 (5). [p.353, Fig.22]. Female: habitus (lateral left side); b, last thoracic segments and urosome (dorsal); c, idem (lateral left side); d, forehead (dorsal); e, idem (lateral); f, rostrum (anterior); g, Mx1; h, Mxp; i, P1 (posterior); j, P2 (posterior); k, P3 (posterior); l, P5. Nota: The specimens seem to agree well with Sars' (1925) descriptions and illustrations, however the distal end of the metasome in lateral view is round instead of being angular and the rostral rami in anterior view are not tapering into sharp points.

issued from : O. Tanaka & M. Omori in Publ. Sero Mar. Biol. Lab., 1992, 35 (4/5). [p.265, Fig.6]. Female (from Izu region, Japan): a, forehead (dorsal); b, idem (lateral); c, posterior part metasome and urosome (dorsal); d, idem (lateral left side); e, rostrum (anterior); f, Mx1; g, Mx2; h, Mxp; i, P1; j, right P5. Nota: Park (1983) states that rostral rami have an obtuse distal end. However, in the present specimen rostrum has a pair of strong spines with a small filament at each apex.

Distribution map of Onchocalanus hirtipes by geographical zones
|
| | | | | | Loc: | | | Antarct. (S Indian), off Mauritania, Canary Is., Azores, off Bermuda: Station "S" (32°10'N, 64°30'W), off W Ireland, S Iceland, ? [Philippines, off Peru, off Galapagos (in C.B. Wilson, 1950, p.273)], Japan (Izu region) | | | N: | 8 | | | Lg.: | | | (1) F: 4,8; (7) F: 5,3; M: 4,04; (15) F: 5,33-5,16; (24) F: 5,7; (445) F: 4,7; (867) F: 5,05; {F: 4,70-5,70; M: 4,04} | | | Rem.: | Bathypelagic. Sampling depth (Antarct.) : 0-1000 m. Sargasso Sea: 1000-1500 m (Deevey & Brooks, 1977, station "S"); This species is closely related to O. wolfendeni but can be distinguished from it. The locality records in the Pacific need confirmation, even though Tanaka & Omori (1992) have well indicated this species near Japan (Izu). According to Vervoort (1950 a, p.33) this species resembles both O. affinis and O. scotti, from wich it distinguishes (see: the shape of the rostrum and genital segment appearance). | | | Last update : 27/01/2015 | |
