Gigantactinidae (Whipnose anglers)
Etymology: Rhynchactis: Greek, 'rhynch' = beak or snout + Greek, 'aktis' = ray (in reference to the illicium that arises near the tip of the snout) (Ref. 86949); macrothrix: Specific name refers to the relatively long secondary filaments of the illicium.

Raios dorsais moles (total) : 4; Raios anais moles: 3. Length of illicium 109-144% SL, distal tip bearing 3-4 small unpigmented filaments, some with tiny distal swelling; distal 28-57% illicial length bearing series of 11-20 secondary filaments, five longest filaments measuring 6-15%SL; each secondary filament with 1-2 unpigmented terminal filaments, some with tiny distal swelling; large specimens (110-113 mm) with secondary filaments darkly pigmented to base of terminal filaments, divided on each side by a narrow, well-defined longitudinal transparent band (Ref. 86949).
