Panulirus homarus is a species of spiny lobster that lives along the coasts of the Indian and Pacific Oceans.

[3] There is variation in the colouration, which parallels other morphological differences; most animals are dark green and have only very small squamae in the grooves of the abdominal tergites.

The original description was simply "[Cancer] macrourus, thorace antrorsum aculeato, manibus adactylis", with a type locality of Mari Asiatico.

[9] The lectotype is the animal portrayed in a watercolour published in 1705 in Georg Eberhard Rumphius' Amboinsche Rariteitkamer.

[3] The original specimen, which was in the collection of Henricus d'Acquet, the burgomaster of Delft has been lost, but the illustration survives, and is held in the Tropenmuseum in Amsterdam.

[3] Despite the vague location given by Linnaeus, the legend to the illustration makes it clear that the specimen was from Ambon, Indonesia.
