Grievella shanki Ferrari & Markhaseva, 2000 (F) | |
| | | | | | | Ref.: | | | Ferrari & Markhaseva, 2000 b (p.1080, Descr.F, figs.F) |  issued from : F.D. Ferrari & E.L. Markhaseva in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1081, Fig.1]. Female (from SE Pacif.: off NW Easter Is.): A, habitus (dorsal); B, idem (lateral left side); C, rostrum (ventral); D, idem (right lateral); E, idem (ventral); F, urosome (dorsal); G, idem (left lateral); H, genital complex (ventral), arrow to location of copulatory opening); I, idem (left lateral); J, idem (right lateral, arrow to oviductal opening); K, caudal rami (ventral). Bars: A, B 1.0 mm; C-J 0.100 mm. Nota: Head and 1st thoracic segment fused, 4th and 5th fused. A1 (24-segmented) reaching 3rd thoracic segment; caudal rami with 4 large, terminal setae, 1 small medial-ventral seta and 1 small lateral-dorsal seta. For the authors the true first thoracic somite is corresponding to Mxp in the publication as the genital complex incoporates the last thoracic somite and the first urosomal somite (= genital complex).

Distribution map of Grievella shanki by geographical zones
|
| | | | Loc: | | | SE Pacific Rise: Hydrothermal vent (hyperbenthic: 2788 m) | | | | N: | 1 | | | | Lg.: | | | (813) F: 2,15; {F: 2,15}
Pr: 1,61 mm; Ur: 0,54 mm (Ferrari, comm. pers.). | | | | Rem.: | Hyperbenthic (depths: 2788 m).
According to Ferrari & Markhaseva (2000, p.1084-1087) the decision to place this species within the Scolecitrichidae is tentative. | | | Last update : 06/01/2015 | |
