Jamstecia terazakii Lee & Huys, 2000 (F) | |
| | | | | | | Ref.: | | | Lee & Huys, 2000 (p.43, figs.F) |  issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.44, Fig.26]. Female (from Okinawa Trough): A, B, habitus (dorsal and lateral, respectively; caudal rami largely omitted); C, caudal rami (dorsal; excluding proximal part shown in A); D, seta II of left caudal ramus (dorsal); E, distal portion of caudal rami (dorsal).l. Scales in microns.

 issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.46, Fig.27]. Female: A, urosome (ventral; left P5 exopod and caudal rami omitted); Bidem (lateral); C, anal somite (dorsal); D, genital field (ventral; left P6 omitted); E, Md; F, Mxp; G, tip of Mxp endopod showing vestigial element, arrowed).. Scales in microns.

 issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.47, Fig.28]. Female: A, A1 (ventral; minute anterior process on segment 1 arrowed); B, Mx2 (damaged); C, A1 segment 7 (ventral); D, distal margin of A1 segment 3 (dorsal; spinular ornamentation arrowed); E, idem (ventral).. Scales in microns.

 issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.49, Fig.29]. Female: A, A2; B, labrum (posterior); C, paragnaths (anterior); D, Mx1 (posterior; inset: anterior surface elements on arthrite); E, A2 endopod (distal armature); F, A2 endopod (lateral armature; arrow indicating 3rd element, probably broken); G, A2 exopod. Scales in microns. Nota: The elongate A2 differs significantly from that of other members of the family in that the free endopod is distinctly shorter than the allobasis and the 2-segmented exopod is strongly reduced in size, bearing a characteristic armature of 1 very long seta and 1 accessory seta.

 issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.51, Fig.30]. Female: A, P1 (anterior); B, P1 (aberrant armature on left expod 3); C, P2 (anterior). Scale in microns. Nota: The left P1 exopod 3 has an atypically long outer distal seta.

 issued from : W. Lee & R. Huys in Zool. J. Linnean Soc., 2000, 129. [p.52, Fig.31]. Female: A, P3 (anterior); B, P4 (anterior); C, outer margin of P4 coxa (posterior). Scale in microns.

Distribution map of Jamstecia terazakii by geographical zones
|
| | | | | | | Loc: | | | Japan (Okinawa Trough) | | | | N: | 1 | | | | Lg.: | | | (915) F: 3,38; {F: 3,38} | | | | Rem.: | epi-hyperbenthic (depths: 583-711 m).
For Lee & Huys (2000, p.50) generic assignment of the new species is hampered by the lack of information on the male. This species is obviously closely related to Andromax muricatus by virtue of the spinous process pattern on the trunk somites, the presence of 2 spinous processes on segment 2 of the female A1 and the shape of the rostrum. | | | Last update : 06/01/2015 | |
