Euaugaptilus truncatus (Sars, 1905) (F) | |
| | | | | | | Syn.: | Augaptilus truncatus Sars, 1905 c (p.14, Descr.F); Farran, 1908 b (p.75, Rem.F) | | | | Ref.: | | | Sars, 1925 (p.269, figs.F); Rose, 1933 a (p.225, figs.F); Sewell, 1948 (p.505); Matthews, 1972 (p.43, figs., Rem.); Lozano Soldevilla & al., 1988 (p.60); Vives & Shmeleva, 2007 (p.213, figs.F,M, Rem.) |  Issued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.LXXXIII, figs.1-13]. Female: 1, habitus (dorsal); 2, idem (lateral left side); 3, rostrum; 4, A2; 5, Md; 6, Mx1; 7, Mx2; 8, Mxp; 9, portion of a distal seta of Mxp (facial and lateral, enlarged); 10, P1; 11, P3; 12, P5; 13, anal segment and caudal rami (dorsal).

 issued from : J.B.L. Matthews in Bull. Br. Mus. (Nat. Hist.) Zool., 1972, 24 (1). [p.43, Fig.11]. Female (from 33°53'S, 90°34'W): Unusual specimen. A, Md (biting edge of mandibular gnathobase); B, Md (mandibular palp); C, Mx1. Nota: Grice & Hulsemann (1968) found a female specimen in the South Pacific, in a haul from 2000 to 970 m which they have suggested may represent a new subspecies of E. truncatus. The specimen was slightly smaller (6.6 mm) than recorded by Sars (7.6 mm) and differed from the typical structure in having one seta fewer than normal on the endopodite of P1 and two fewer on the 1st endite of Mx1; in having an extra tooth on the gnathobase and in the greater reduction of the mandibular palp of Md. The difference in body length and in setation of Mx1 and P1 can be attribuated to possible natural variation; the difference in the mandibular structure may be an abnormality. Until more is known about the occurrence of this form, it seems best to record it as a variant.
