is distinguishable by its very elongate Ur1 armed with a pair of anterolateral setules and the symmetrical P5 in the female the right posterior corner of Pdg5 modified into a long, sickle-like process in the male. Three new species of Pontellopsis from Indonesian waters are herein described. The establishment of a new species-group, the P. Pontella labuanensis does not belong to any of the known three species-groups of Indo-West Pacific Pontella, in having the symmetrical genital somite and the exopods of the fifth legs virtually naked in the female, and the rostrum with double convex lenses and the exopods of the fifth legs with two subequal thumbs, in the male. This may be an endemic species which has a preference for low salinities. Labidocera muranoi, which was collected from Cilacap Bay, a mangrove estuary facing the Indian Ocean, belongs to the Labidocera kroyeri-group and is distinguished from other species of this group by the urosomal somites and the fifth legs in the female and by the fifth metasomal somite and the fifth legs in the male. It seems to be a neritic species inhabiting coastal waters shallower than 15 m in depth, and within 1 km offshore. Labidocera javaensis, which belongs to the Labidocera pectinata-group, is distinguishable from other species of this group by a combination of characters of the genital complex and the fifth legs in the female and of the fifth metasomal somite, the first urosomal somite, and the fifth legs in the male. muranoi and Pontella labuanensis, are described and illustrated from specimens collected in coastal waters of Java, Indonesia, and their relationships to related species are discussed. Three new species of the family Pontellidae, Labidocera javaensis, L. d.-sinilobata, as well as the establishment of a P. The establishment of four new species-sub-groups of L. Ponetlla papuensis does not belong to any of the known five groups of Indo-West Pacific Pontella, in having Ur1 with a beak-like posterodorsal process and almost symmetrical Re's (exopods) of P5 in the female, a rostrum with double convex lenses, the chela of the right P5 with a bilobed thumb, and the inner margin of that chela armed with a large process, in the male. detruncata species-group, is distinguishable from other species of this group by the very elongated Ur1 (urosomite 1) and the asymmetrical P5 in the female and the Pdg5 (pediger 5) and P5 in the male. Labidocera kaimanaensis belongs to the L.
Two new species of the family Pontellidae, Labidocera kaimanaensis and Pontella papuensis are described and illustrated from specimens collected in Arguni Bay, West Papua, Indonesia.
Since the descriptions of these species groups and also species as yet unassigned to groups were often not given in sufficient detail, we provide re-descriptions of their species groups and their zoogeography in Indonesian waters, adjacent waters, and the world oceans The Labidocera pectinata -group includes L. The Labidocera kroyeri -group includes L. The Labidocera detruncata -group includes the following species: L. These species divided into five species-groups, detruncata -, kroyeri -, minuta -, pectinata - and an unassigned group, based on its morphological characters. sinilobata Shen & Lee, 1963, and seven previously recorded species from Indonesian waters. kaimanaensis Mulyadi, 2014, three new records, L. Among these species, there were three recently described species, Labidocera javaensis Mulyadi, 1997, L.
Plankton samples collected from nine sites around coastal areas of Indonesia from 2003 to 2015. Thirteen species of the genus Labidocera Lubbock, 1853 were identified.
