description

We add the following new observations for P. inermis: scales with peripheral cteni; vertebrae 10 + 16; supraneurals 3; predorsal formula 0 / 0 + 0 / 2 / 1 + 1; dorsal pterygiophores in interneural spaces 9 – 13 1 / 1 / 1 + 1 / 1 / 1 + 1, 1 / 1 / 1 + 1 / 1 + 1 / 1 + 1 or 1 / 1 / 1 + 1 / 1 + 1 / 1 + 1 + 1; no trisegmental pterygiophores associated with dorsal fin; terminal dorsal pterygiophore in interneural space 18; no trisegmental pterygiophores associated with anal fin; terminal anal pterygiophore in interhaemal space 4 – 5; ribs present on vertebrae 3 through 10; epineurals present on vertebrae 1 through 11; parhypural and hypurals autogenous (Figure 5 A); well-developed hypurapophysis on parhypural; epurals 3; single uroneural (posterior uroneural absent); ventral tip of cleithrum with well-developed posteroventral process; proximal tip of first anal-fin pterygiophore near distal tips of parapophyses on vertebra 10. Morphometric data are summarised in Table 24.

diagnosis

Diagnosis. The following combination of characters distinguishes P. inermis from congeners: segmented dorsal rays 16 – 18; third dorsal spine longest, 15.6 – 18.8 % SL; lateral line complete, interrupted or incomplete, consisting of 12 – 28 tubed scales; predorsal scales extend anteriorly to middle or posterior interorbital (at point ranging from vertical through posterior edge of orbit to vertical through middle of pupil); preopercle with 3 – 11 weak serrations on posterior (vertical) edge and 0 – 2 weak serrations on ventral edge (none antrorse).
