A new species from the subfamily Comesomatinae is described from the back-reef platforms of the central part of the Maldivian archipelago. Paracomesoma susannae sp. nov. is characterized by a large-sized body, very long cephalic sensilla (72–91 mm long), lateral differentiation of punctuations, and, in the males, 19–22 minute precloacal supplements, relatively short spicules (2.3–2.9 anal body diameter) and a hook-like structure in the distal end of the gubernaculum. Paracomesoma susannae sp. nov. is the only species so far described of the genus which appears to have such a low ratio of the outer labial and cephalic sensilla (about 0.02). An emended diagnosis of P. paralongispiculum is proposed, along with an updated and modified key to all the valid species of the genus Paracomesoma.

Abstract
A new species from the subfamily Comesomatinae is described from the back-reef platforms of the central part of the Maldivian archipelago. Paracomesoma susannae sp. nov. is characterized by a large-sized body, very long cephalic sensilla (72–91 mm long), lateral differentiation of punctuations, and, in the males, 19–22 minute precloacal supplements, relatively short spicules (2.3–2.9 anal body diameter) and a hook-like structure in the distal end of the gubernaculum. Paracomesoma susannae sp. nov. is the only species so far described of the genus which appears to have such a low ratio of the outer labial and cephalic sensilla (about 0.02). An emended diagnosis of P. paralongispiculum is proposed, along with an updated and modified key to all the valid species of the genus Paracomesoma.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
