Morphology | Morphometrics
A lycodine zoarcid as defined by Anderson (1994), with the following combination of characters: 7 branchiostegal rays, interdigitating ceratohyal–epihyal articulation, palatal arch reduced, posterior hyomandibular ramus longer than anterior, cranium narrowed, supratemporal commisure and occipital pores absent; scales, pseudobranch, pyloric caeca, pelvic fins, lateral line, vomerine and palatine teeth present.
Body moderately robust; tail laterally compressed and moderately elongated; head slightly depressed; snout slightly pointed; eyes elliptical, not reaching dorsal profile of head; mouth inferior, with upper jaw greatly protruding, end of maxilla extending to posterior margin of pupil; lower lip with a small posterior lobe; nasal tube short, unpigmented, not reaching upper lip. Gill slit extending ventrally to just below ventral edge of pectoral fin base. Opercular lobe small.
Cephalic lateralis pores moderately large with the exception of the eighth preoperculomandibular. Nasal pores 2, first nasal pore located anteromesial to nasal tube. First and fourth postorbital pores present in the holotype; only the fourth in the paratypes; suborbital pores seven in the holotype, six in the paratypes; preoperculomandibular pores eight; interorbital pore absent; supratemporal commisure and occipital pores absent.
Lateral line configuration with two rows of neuromasts: lower lateral line beginning just behind the fourth postorbital pore, and extending ventrolaterally to the end of the tail; middle lateral line, originating above anal fin origin, with scattered neuromasts, extending to end of tail. Some neuromasts as a short row at predorsal area.
Flesh and skin firm; body covered with small cycloid scales extending anteriorly to mid-pectoral area. Nape and dorsal area anterior to dorsal fin origin naked. Vertical fins naked anteriorly, half bases scaled posteriorly; anterior part of caudal fin scaled. Belly and pectoral fin bases naked.
Vertebrae asymmetrical, 24 + 78 in all. Last precaudal vertebra associated with dorsal fin rays 18–19.
Dorsal fin origin associated with vertebra seven with 0-1 free predorsal pterygiophores. Terminal dorsal fin ray associated with second or third preural vertebrae. Anal fin origin associated with first caudal vertebra with two to three preanal pterygiophores. Terminal anal fin ray associated with second preural vertebra, one epural. First preural centrum, ural centrum, parhypural and hypurals fused into one element. Caudal fin rays ten with two epural, four upper hypural and four lower hypural rays (Ref. 79065).
