Name

• Lestidium rofeni H.-C. Ho, K. Graham & B. Russell, 2020

• Etymology: The species is named after Robert R. Rofen (previously R. R. Harry), former research director of George Vanderbilt Foundation, Stanford University, who contributed a lot of knowledge on paralepidid fishes.

• Diagnosis: A species in the Lestidium prolixum species complex with a complete lateral line and a simple luminescent duct originating below opercle.; L. rofeni can be further distinguished from two other congeners in the species complex in having 30‒33 anal-fin rays; prehaemal vertebrae 36–38 and total vertebrae 87–90; lateral-line ending at caudal fin base, with 123–139 scales; DFO clearly behind tip of adpressed pelvic fin; V–D 6.7–8.7% SL and 30.2–36.7% V–A; 5‒7 lateral-line scales and 5‒8 vertebrae between VFO and DFO; scattered melanophores away from upper margin of lateral line before VFO, entirely translucent on remaining section of lateral line; abdominal ridge with none or scattered melanophores.
