Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); boklundi: The species name is dedicated to the collector, aquarist Jørn Boklund, of Denmark (Ref. 84038).
Eponymy: Jørn Boklund is a Danish aquarist who collected the holotype (2009) from seasonal pools in North Luangwa National Park, Zambia. He is a friend of the author. (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 17; Anal spines: 0; Anal soft rays: 17 - 18. Nothobranchius boklundi is distinguished from all other species of the genus by a unique combination of characters in females that consist of pale red elongate spots over the dorsal and anal fin rays only; males similar to the other members of the N. brieni species-group and differing from all other species of the genus by the caudal and anal fin proximal portions being spotted with a broad light submarginal band and dark margin, the absence of a dark margin on the dorsal fin, the absence of spots on the head and no black margin to the scales (Ref. 84038). This species differs from the other members of the N. brieni species-group by the regular reticulated pattern on the body; its light blue iris; the caudal fin having a dark margin, its proximal portion with red dots or spots; dorsal fin without light margin, without distinct black spots anteriorly; anal fin completely covered with irregular rows of red spots, distal portion yellow and border not distinctively pigmented (Ref. 84038).
The type locality was at the time of collection of the type material a pond about 100 m in diameter with a depth of about 1.5 m in its centre (Ref. 84038). The water was light clay grey in color, slightly turbid and aquatic vegetation which includes a species of Nymphea (Ref. 84038).
