That is Synalpheus pinkfloydi. This newspaper article says the reason it was named for the band is because of a legend that the band once played so loud that it killed fish in a nearby lake. Plus, one of the authors is a rock and roll fans, previously naming a shrimp after Mick Jagger.
The article missed a damn good bit of the paper, though:
Distribution: Presently only known from the type locality on the Pacific side of Panama; likely more widespread in the tropical eastern Pacific, but unlikely to occur on the Dark Side of the Moon due to lack of suitable habitat.
Hat tips to GrrlScientist, Miss Mola Mola, and Mark Carnall.
