Lethrinus harak, the thumbprint emperor, Jimothey, blackblotch emperor or blackspot emperor, is a species of marine ray-finned fish belonging to the Family Lethrinidae. the emperors and emperor breams. This species is found in the Indo-Pacific region.

Taxonomy Lethrinus harak was first formally described as Sciaena harak in 1775 by the Danish zoologist Johan Christian Fabricius and published in Descriptiones animalium edited by Carsten Niebuhr. Fabricius based his description on the notes of Peter Forsskål who had died while on an expedition, which Neibuhr was also a member of, to Arabia. No Type locality was given but it is assumed to be the Red Sea. Some authors place the genus Lethrinus in the monotypic subfamily Lethrininae, with all the other genera of Lethrinidae placed in the Monotaxinae, however, the 5th edition of Fishes of the World does not recognise the subfamilies traditionally accepted within the family Lethrinidae as valid. The family Lethrinidae is classified by the 5th edition of Fishes of the World as belonging to the order Spariformes.

Etymology Lethrinus harak has the specific name harak which Forsskål used in his notes, deriving it from the Arabic name for this fish in the Red Sea, Abu m'hárrak.

Description Lethrinus harak has its dorsal fin supported by 10 spines and 9 soft rays while there are 3 spines and 8 soft rays supporting the anal fin.
