Etymology: Ilyophis: Greek, ilyos, -ou = cave + Greek, ophis = serpent (Ref. 45335).
Eponymy: Arx is Latin for castle, alluding to Dr Peter Henry John Castle (1934–1999), who “laid the foundations of modern work on synaphobranchid eels”. (See Castle) (Ref. 128868), visit book page.

背鰭 (合計) : 309 - 322; 臀鰭: 235 - 261; 脊つい: 131 - 135. This species is distinguished by the following characters. body no dcales; trunk relatively long
(about 21-29% of TL); dorsal-fin origin (DFO) above the posterior third of pectoral fin; gape of mouth moderate, extending to near rear margin of eye; teeth not compound; intermaxillary teeth conical with approximately 16-24 teeth in the tooth patch, inner teeth on the patch nearly twice as large as the outer teeth; vomerine teeth contiguous with intermaxillary teeth with approximately 25-30 teeth, irregularly biserial to triserial anteriorly and uniserial posteriorly; both the intermaxillary and vomerine teeth set in beds of papillose tissue; maxillary teeth small, set in irregular rows, 3 rows anteriorly to 6 rows posteriorly; dentary teeth similar to maxillary teeth except they are slightly larger and more uniform in size anteriorly; lateral line short, confined to the anterior half of body (ca. 35-45% of TL); cephalic lateralis pores with supraorbital (SO) 3, infraorbital (IO) 5 (including adnasal, AD), preoperculomandibular (POM) 6-10; total vertebrae 129-136 (Ref. 132084).
Body shape (shape guide): eel-like; Cross section: oval.
Body shape (shape guide): eel-like; Cross section: oval.
This species may be a specialist of seamounts, ridges and island slopes, suggesting that it may only be found associated with rough topographies (Ref. 132084).
