 issued from : M.J. Grygier & S. Ohtsuka in Zool. J. Linnean Soc., 2008, 152. [p.483, Fig.17]. SEM. Female (from two non-ovigerous paratypes): A, anterior half of cephalothorax (lateral); B, anteroventral part of cephalothorax (i.e. 'face') between oral papilla (o) and bases of A1 (top corners), showing two pairs of pores and two pairs of scars; C, reticulations of lateral side of cephalothorax; D, reticulations of forehead, showing pair of hair-like sensilla and pair of pores (dorsal to left); E, P2-P4 (lateral view); F, detail of coxal spinulation of a right swimming leg (proximal to left; G, site of absent inner seta (arrow) of 1st endopodal segment of right P1.

 issued from : M.J. Grygier & S. Ohtsuka in Zool. J. Linnean Soc., 2008, 152. [p.485, Fig.19]. SEM. Female (from two non-ovigerous paratypes): A, dorsal surface of free pedigers1 and 2 (anterior at top; arrows indicating obscured pair of large pores); B, dorsal surface of free pediger 3 (anterior at top); C, dorsal surface of free pediger 4 and genital compound somite (g; letter placed on indistinct dorsal suture) (anterior at top); D, telson (t) and caudal rami (f) (dorsal view); E, part of posterior margin of penultimate segment of urosome (posterior to right); F, genital compound somite (ventral view), anterior at bottom, showing copulatory pore (arrow) and small ventral knob on posterior part (above).

 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.

 issued from : M.J. Grygier & S. Ohtsuka in Zool. J. Linnean Soc., 2008, 152. [p.493]. Key to the Ryukyu species of the Maemonstrilla hyottoko species-Group. M. okame Female: 1 - Cuticle of cephalothorax, A1, lateral sides of trunk, dorsum telson, and caudal rami reticulated; outer faces of P1-P4 and dorsum of free pedigers, genital compound somite, and penultimate somite spinulose. Cephalothoracic reticulations comprising ridges with abundant or sparse spinules; simple or complex cuticular ornamentation within at least some meshes. 2 - Oral papilla small, directed more anteriorly than ventral and flanked by 'puffed cheeks'. Genital compound somite lecking dorsal transverse ridge. Compare with M. simplex, M. hyottoko, M. polka, M. spinicoxa.
