palpus [′pal·pəs]
(invertebrate zoology) A process on a mouthpart of an arthropod that has a tactile or gustatory function. Any similar process on other invertebrates. Palpus a segmented appendage of the jaws (mandibles and first and second maxillae) in crustaceans, myriapods, and insects, equipped with various sense organs (tactile organs and chemore-ceptors). The palpi are well developed and completely represented in crustaceans; in myriapods and insects there are no palpi on the mandibles. In many insects, especially those with a sucking-type mouth apparatus, the palpi are reduced. Want to thank TFD for its existence?
