Planche 3 Issued from : D. Jeon, W. Lee & H.Y. Soh in J. Crustacean Biol., 2018, , 38 (1). [p.49, Fig. 3]
Mele: A, right A1; B, 3rd exopodal segment of P1 showing 2 serrate outermost setae (anterior view); C, right P2 (anterior view); D, left P3 (anterior view); E, right P4 (anterior view).
Asterisks indicate anterior pores.
Scale bars in µm.
Nota: - A1 clearly 5-segmented, genetally directed straight forward, but bent slightly upward at joint between 3rd, 4th segment. Geniculation prsent between 4th and 5th segments. 5th segment bent almost 180° to inner side.
- Armature of A1 :
- 1st segment armed with pinnare spine 1 on inner distal part, arising slightly dorsally;
- 2nd segment armed with 6 setal elements: 4 robust, densely pinnate spines (2v 1-3, 2d 1); biserially plumose IId seta developed in typical, strap-like form; elongated spine 2d 2, biserially plumose with fine setules, reaching proximal margin of 4th segment.
- 3rd A1 segment armed with 3 setal elements pinnate spine 3 on inner distal side and 2 biserially plumose strap-like setae IIId, IIIv located more proximal; IIId short, only as long as its segment, IIIv slightly longer than IIId proximal half. Outer proximal region of segment with groove.
- 4th segment: proximal half robust, distal part thinner; segment armed with 8 setal elements (4V 1-3, 4d 1-2, 4d a, IV v, 4 aes). 5 short spines 4 v 1-3, 4d 1, 2 robust, pinnate on inner side, all subequal in lengthnbut 4v 3 slightly longer than others; minute spine 4d a naked, notably thinner than others.
- 5th segment armed with 12 setal elements. Typical branced setae absent. Short apical aesthetasc (6aes arising from tips. 3 robust spines (6 1, 6 2, 6 3) on distal part of segment most distal spine 6, laterally on outer side; 6 2 near 6 1 but more dorsally, slightly proximal to it; most proximal spine 6 3 situated dorsally; 6 1 pinnate with short spinules, 6 2 and 6 3 with relatively long thin setules. Medium long, biserially plumose seta Vv situated ventrally. 6 unmodified setae (A-D, a, b) arising from outer distal, part, setal elements A-D relatively longer, thicker than elements a, b. Inner dorsal margin wuth 3 transverse serrate ridges consisting of numerous minute spinules.
