Espèce Maemonstrilla okame - Planche 5 de figures morphologiquesissued 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.


Espèce Maemonstrilla okame - Planche 6 de figures morphologiquesissued 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.
