Etymology: Myxine: Ancient Greek word for a slimy fish: myxa, slime; -inus, one who, referring to copious amounts of slime produced by M. glutinosa (See ETYFish); pequenoi: In honor of German Pequeño Reyes (b. 1941), Universidad Austral de Chile, for his work on Chilean fishes and for providing holotype (See ETYFish).
Eponymy: Dr German Enrique Pequeño Reyes (d: 1941) was Professor of Zoology at and Director of the Instituto de Zoología, Ernst F Kilian, Universidad Austral de Chile (1973–2007). [...] (Ref. 128868), visit book page.

Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ).東南太平洋: 只有模式標本外海的巴爾第畢亞，智利。
