Ilyophis singularis
is described on the basis of two specimens (248–270 mm in total length) collected from the northeastern South China Sea at a depth between 1,612 and 1,665 m. The new species is characterized by a low number of vertebrae, with 116–118 total vertebrae, which is the smallest known for a species in
Ilyophis
. In addition, it differs from its congeners by the following combined characteristics: preanal vertebrae 36–37; sensory pores in supraorbital series 3 (pores absent above eye); sensory pores in infraorbital series 7 or 8 (2 or 3 pores behind eye); sensory pores absent on frontal and supratemporal regions; and body naked. The uncertainties for defining the two subgroups in
Ilyophis
are also discussed. |
