Word origin: Lysmata appears to be from the Greek roots Lys meaning loose and mat, -aeo, -eo, meaning foolish or idle. The species amboinensis is from the Latin roots ambo meaning both; in meaning without ; and -ensi, =s meaning a sword. The literal translation seems a bit confusing and the genus Lysmata may refer to the cleaner shrimps leaving the substrate (loose) to clean fish capable of eating them (foolish). The meaning of the species name amboinensis can be literally translated as "both without a sword", but the significance of this is not clear.

The order Decapoda means "ten legs" (Deca indicating ten and pod meaning foot. The suborder Nantia refers to shrimp. The family Hippolytidae are the "cleaner" shrimp. There appears no Latin or Greek root for Nantia and Hippolytidae appears to be a combination of hippo meaning "horse" and ly another word for loose, and idae being a standard suffix for an animal, although generally used on family designations.
