Etymology: Xenolumpenus: Name from Greek, Xeno (= strange), and Latinized Danish, lumpenus (type genus of the subfamily Lumpeninae), for the elongated pectoral, pelvic and anal fin rays.; longipterus: Name from Latin, longus for long and Latinized Greek pteron for wing; referring to the elongate pectoral fins.

Morphology | Morphometrics
(total): 46 - 48;
soft rays: 30;
Vertebrae: 52 - 54. This species is distinguished by having the following characters: DXLVI-XLVIII; A II,28-30; membrane extremely incised, rays elongate; 11 pectoral-fin rays, including 3 ventralmost rays free from others and the longest ray 36.5-40.2% SL; pelvic fin rays elongate, membrane well-incised, and rays unbranched; 2 mandibular pores; 1 or 2 large black blotches on pectoral fin; black ocellus on caudal fin (Ref. 84251).
The specimens have well-developed ovaries containing ca. 1.5 mm diameter eggs, suggesting the spawning of the species occurs in autumn (Ref. 84251).
