Total myomeres 106-112 (34-51 + 59-76); compared to other trachipterids, preanal length greater in postflexion-transformation stage, eye smaller (ED 26% HL vs. 31-34%), and jaw depth shallower (JD 36% HL vs. 51052%); dorsal epaxial and ventral hypaxial pigment; pigment on dorsal fin pterygiophores; in later stages, deep body, more rounded anteroventral profile, and narrower, elongate tail.
Pigmentation:
Preflexion: on forebrain and onto ascending process of premaxilla; on jaw; anterior and posterior to cleithrum; dorsolaterally on gut; series dorsally on epaxial myomeres; postanal series on hypaxial myomeres; a few in caudal region.
Flexion-postflexion-transformation: increasing over brain, anterior and posterior to eye, and laterally on body; on dorsal pterygiophores.
Juvenile: finely scattered with concentrated small patches over entire body; 2 large concentrated patches on epaxial myomeres; dorsally on pterygiophores; on ascending process of premaxilla.
Sequence of fin development: dorsal and pelvics, caudal, pectorals. |
