 Issued from : K. Cho, W.-S. Kim, R. Böttger-Schnack & W. Lee in J. Nat. Hist., 2013. [p.19, Fig.6]. Female (10°30'N, 131°20'W): A, habitus (dorsal); B, habitus (lateral); C, urosome (dorsal); D, urosome (lateral). Scale bars in µm. Nota : Exoskeleton moderately chitinized, surface covered with numerous small pits. Prosome 1.6 times length of urosome, excluding caudal rami, about 1.5 times urosome length including caudal rami. P2-bearing somite with out dorsoposterior projection in lateral aspect. Integumental pores on prosome as indicated fig.6A, B. Pleural areas of P4-bearing somite with small pointed posterolateral corners. Integumental pores on urosomites (fig.6D) similar to T. pacifica. Genital double-somite about 1.6 times as long as postgenital somites combined, with elongate flask-like form ; largest width measured at anterior third, lateral margins slightly rounded, posterior 2/3 tapering gradually. Dorsal surface paired genital apertures located at about 2/5 of distance from anterior margin and paired secretory pores posterior to genital apertures. Anal somite slightly longer than wide ; 1.5 times longer than caudal rami. Caudal ramus about 1.5 times as long as wide.
