Abstract

A modern diagnosis of Guernea is given, its species listed with their biogeographical distributions based on Barnard and Barnard (1983). Two species, Guernea ipilya and G. yamminye are described from rubble in shallow water on the Great Barrier Reef. Guernea ipilya differs from its sympatriot, G. endota, in lack of mid-dorsal spines on the urosome, with the side spines smaller: spinose telson; much longer and denser setae on article 2 of pereopod 5; larger posterior lobe of coxa 5; shorter anterior lobe of coxa 6; stouter antennae; lack of hump on urosomite I; short pereopod 6; lack of major posterior spines on article 6 of pereopods 3-4; and lack of spines on rami of female uropod 3. Guernea yamminye differs from G. reticulatus in the lack of serrations on article 2 of pereopod 1 and the weaker envelopment of article 6 by article 5 on pereopod 7.
