Etymology: Oxyurichthys: Greek, oxys = sharpen + Greek, oura = tail + Greek, ichthys = fish (Ref. 45335); zeta: Name from the Greek ζήτα (zeta) which gave rise to the last letter of the Roman alphabet u; this elusive species is known from only two specimens and several photographs and is the last species in this revision, although it is unlikely to be the last species described for this genus.

Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 7; Các vây lưng mềm (tổng cộng) : 12; Tia cứng vây hậu môn: 1; Tia mềm vây hậu môn: 13. This species is distinguished by the following characters: dorsoposterior of eye without tentacle, cornification or spot; no constriction at premaxillary symphysis of upper lip; first dorsal-fin spines are short, posteriormost spines reaching just beyond second element of second dorsal fin when appressed; anterior nares in small tube and not darkly pigmented; nape has a low membranous crest; absence of gular spots; not spots on scales on dorsum; when alive, with a large blackish blotch on posterior part of first dorsal fin and 4 large diffuse spots along the mid-side of body and one spot on caudal-fin base, also indistinct; no saddle on caudal peduncle; cycloid (reduced ctenoid) scales; naked prepelvic region; lateral scales 100-112; pectoral-fin rays 22; pelvic fins are dusky, not barred or mottled (Ref. 103856).
Specimens are photographed hovering over a dark soft substrate. One individual at Lovina Beach, Bali, appears to be at the entrance of a large burrow (made by another organism).
