“…Based upon morphology of the adults, GUINOT (1979) andMANNING andHOLTHUIS (1981) considered yet another new subfamily (Camptandriinae) in the Ocypodidae where Paracheistostoma cristatum would be allocated together with various species of other genera. From the larval view point, the validity of this new proposal can only be confirmed with the study of zoeae of the many species inc1uded in this subfamily.…”

Misael Domingues Rodrigues 2Nilton José Hebling 3Six zoeal stages and the megalopa of the comestible crab Ucides cordatus cordatus (Linnaeus, 1763) are described and illustrated. The larvae were reared in the laboratory at temperature 25 ± lOC and water salinity of 24 0 /00; duration of stages and survival rates were measured. Comparisons with the descriptions of the zoeal morphologic characters of Ocypodidae and Gecarcinidae perrnited to include definitively U. c. cordatus in the family Ocypodidae, subfarni1y Ocypodinae. INTRODUCTIONThe comestible crab, Ucides cordatus cordatus, is very commom in the mangrove forests of the Western Atlan tic coast, occurring, according to COELHO & RAMOS (1972), from Florida, Antiles, northern South America, Guiana to Brazil (to the State of Santa Catarina).8ased upon the morphology of the adults, the genus Ucides Rathbun, 1897 has characteristics of both families Gecarcinidae and Ocypodidae. H. MILNE EDWARDS (1837), LEBOUR (1928), RATHBUN (1918RATHBUN ( , 1933, HOLTHUIS (1959), BRIGHT (1966) and PRAHL & MANJARRÉS (1984) considered it in the family Gecarcinidae while CHACE & HOBBS (1969) , TURKA Y (1970, WARNER (1977) and MELO (1985) in the farnily Ocypodidae.ln this paper aredescribed and illustrated alI the larval forms of U. c cordatus.The larval characters are compared with those of the other species of Gecárcinidae and Ocypodidae in order to help solve the controversal systematic position of this genus. MATERIAL AND METHODSOvigerous Jemales of U. c. cordatus were collected on January 18, 1981Research supported by CAPES -PICO. Revta bras. Zoo!.in the mangroves in the canal of Bertioga (23°51 'S, 46°09W), northern litoral of São Paulo, Brazil. After eclosion 60 zoeae were isolated in Petri dishes of 20 mi, with sea water having a salinity of 24 0 /00 and maintained in a climatic room at 25 ± 1 ° C with a photoperiod of 12 hours light and dark. During ali their development, the larvae were fed with freshly hatched nauplii of Artemia salina, after daily changes of water.Dead larvae were fixed and preserved in a mixture of ethol a1cohol 70% and glycerine in a proportion of 1: 1. The exuviae were preserved in glycerine.Measurements and designs were made using a Zeiss microscope with drawing tube. When possible 10 larvae of each stage were analyzed.The following symbols were adopted for the diferent larval stages : I, first zoeal stage; II, second zoeal stage; III, third zoeal stage; IV, fourth zoeal stage; V, fifth zoeal stage that produces zoea VI; V I, fifth zoeal stage that produces directly the megalopa; VI, sixth zoeal stage; MI , megalopa produced by zoea V I ; M2 , megalopa produced by zoea VI.The figures and morphological descriptions of the fifth zoeal stage and of the megalopa were based, respectively, upon stages V and M 2 , because they were most common in the larval development. For stages V I and MI only the alterna te morphologies were mentioned in relation to V and M2 •

“…Many aspects of the ecology of Ocypode species have been investigated (see reviews of Vannini, 1976;1980a, Little, 1983, but comparatively few studies have been carried out on O. cursor. The distribution of Ocypode cursor (Linnaeus, 1758) extends from west Africa into the Mediterranean where its distribution appears to be expanding (Manning and Holthuis, 1981;Ziese, 1985;Glaubrecht, 1992). The only field studies on this species in the Mediterranean are those of Gilad- Shuchman and Warburg (1977), Shuchman and Warburg (1978) and Warburg and Shuchman (1979).…”

SUMMARY: Aspects of the ecology and behaviour of Ocypode cursor were studied on the beaches of Northern Cyprus. The crabs were widely distributed around the north coast of the island, occurring on 68 of the 77 sandy beaches investigated. At the main study beach at Alagadi, crabs occupied a band approximately 12 m wide; starting approximately 3 m horizontally from the edge of the sea (tidal fluctuation was minimal). Most small burrows occurred near to the sea, with the burrows of larger crabs predominating higher up the beach. Burrow numbers varied during the summer which was mainly attributable to variations in the numbers of burrows of juveniles. The sex ratio of emergent crabs also varied during the summer, possibly reflecting burrow oriented behaviour of reproductive females. There were strong correlations between burrow diameters and carapace lengths of the occupant crabs. There was a positive correlation between the presence of crab burrows and the number of people using sections of beach. The crabs were principally nocturnal, benefitting from food discarded by tourists. They also scavenged animal carcasses and were active predators of turtle eggs and hatchlings. Crab burrows usually had a single opening oriented towards the sea and those cast were L-or J-shaped. Burrows did not penetrate to the water table. The water content of the sand at the bottom of burrows was around 14 % by weight. Their burrows in the well-sorted sand provided the crabs with a thermally stable environment.

Milne-Edwards, 1879, P. riisei Stimpson, 1860 para Coryrhynchus Kingsley, 1879 e P. botti Türkay, 1968, P. gracilipes Stimpson, 1871 e P. minuscula Coelho, 1972 para Ericerodes Rathbun, 1897; Coryrhynchus algicola Stebbing, 1914, (classificada como Podochela por vários autores), permanece como Coryrhynchus. Podochela meloi Sankarankutty, Ferreira & Cunha, 2001, é transferida para Inachoides H. Milne-Edwards & Lucas, 1843 (Inachoididae). São apresentados caracteres diagnósticos e chaves de identificação para os gêneros e espécies estudados.
