N); Suarez-Morales, 2011 (p.8, 11) |  issued from : M.J. Grygier & S. Ohtsuka in J. Crustacean Biol., 1995, 15 (4). [p.710, Fig.5]. Female (from Tanabe Bay, Japan): A, habitus (lateral; most setae omitted from appendages); B, idem (dorsal; setae omitted from A1); C, anterior end (ventral); D, right A1 (lateral view); E, posterior part of urosome (dorsal); setules omitted from all but 2 of longer caudal setae. Abbreviations (for D, see Fig.6): an = A1 or 1st segment thereof; cg = cerebral ganglion; e, cup of nauplius eye; gs = anterior part of genital double-somite; op = oral papilla; os = ovigerous spines; ps = pit setae; s = simple seta; dc = scars.

 issued from : M.J. Grygier & S. Ohtsuka in J. Crustacean Biol., 1995, 15 (4). [p.712, Fig.6]. Female: Semischematic diagram of newly devised nomenclature of basic setal armature of A1 in female monstrilloid copepods. it is drawn in dorsal view and a little from the medial side, assuming the antennule is held in its typical orientation, pointing straight forward from the head. There are 4 main kinds of setae: Short, tapered, often spinelike setae (1-6) are arranged more or less medially in clusters of 1-5-1-5-1-2 from proximal to distal; in each group of 5, two are more dorsal (d1-2) and three more ventral (v1-3); Long, setulose, straplike setae (II-V) are associated with the first type in groups of 0-1-2-2-3-0, respectively, and are directed dorsally (d), ventrally (v), or, in one case, medially (m). There are 2 aesthetascs (aes), 1 of them ventral (4aes), the other apical (6aes). There are 6 setae (b) of variable form subapically on the antennule's outer edge; the three more dorsal ones are often highly branched (b1-3); of the others, the middle one may be slightly branched (b5) and two are simple (b4, b6). In some species, like M. hamatapex, none of the b-setae are branched (see Fig.5D

Female: A, right P1 and coupler (posterior view); B, right P2 and coupler (anterior view); ; probable length of broken seta of basis shown as dashed on left leg 2); C, left P3 with short seta on basis (arrow) (posterior view); D, left P4 and coupler (posterior view); E, basis of right P2 (posterior view; enlarged from C, showing sclerite between basis and exopod (arrow)); F, basis of right P2 (anterior view enlarged from B); G, outer apical seta and spinelike seta of exopod of right P4 (posterior view); H, P5 (anterior view, showing aberrant inner seta on right leg.

 issued from : M.J. Grygier & S. Ohtsuka in Zool. J. Linnean Soc., 2008, 152. [p.499, Fig.29]. Female: Dorsal and lateral pore and pit seta patterns, from rear of cephalothorax through genital compound somite. Symbols: dots (three sizes) = pores; larger circles = pits of pit setae. Pattern based on SEM and light microscopical examination.
