Etymology: Limatulichthys: Latin, limatus, -a, -um = sandpapered + Greek, ichthys = fish; nasarcus: Derived from the Latin nasus, meaning snout, and arcus, meaning bow-shaped, in reference to the rounded snout of the species when compared to its congener Limatulichthys griseus.

背面の脊椎 (合計) : 1; 背鰭 (合計) : 7; 肛門の骨: 1; 臀鰭: 5. Limatulichthys nasarcus differs from L. griseus by the possession of the following characters: anterior abdominal plates half the size of those at center of abdomen (vs. plates similar in size); spots across the entire dorsum, including snout and head, less than half of diameter of naris (vs. indistinct spots larger or equal than diameter of naris); lateral portion of head and opercle with dark well-defined spots, larger than those on dorsum (vs. spots on lateral portions of head and opercle equal in size to those on remainder of body); profile of snout in dorsal view broadly rounded (vs. acutely triangular); head longer (21.4-24.2 SL vs. 17.7-21.0%); and longer anal fin (15.7-18.0 SL vs. 13.7-15.6%) (Ref. 97714).
