Desenvolvimento juvenil de Hepatus pudibundus (Herbst) (Crustacea, Decapoda, Calappidae), em laboratório

The Hepatus pudibundus (Herbst, 1785) juvenile development was studied in laboratory, under the morphological and systematical stand points. The eight early juvenile stages were obtained from larvae hatched from eggs of two ovigerous females, collected at the northern coast of the State of São Paulo, Brazil. The experiments were carried out in a climatically controlled room at 25 ± 1°C, and steady saltness of 34 . The youngs were maintened individually and food consisted of Artemia sp. nauplii and fragments of fish muscle.The first juvenile stage were particulary drawn and described. For the remaining juvenile stages the most representative frameworks were picked out, which allowed the characterization of the first eight stages. According to juvenile morphology studies, it was noted that secondary sexual characters differentation begins from the third stage.

A new species of Physalaemus (Amphibia; Leptodactylidae) from the Atlantic forest in southeastern Brazil

A new species of leptodactylid frog, Physalaemus atlanticus, is described from Ubatuba, northern coast of São Paulo in southeastern Brazil. The new species belongs to the Physalaemus signifer species group and is characterized by the following set of characters: small size (males 20.1-22.1 mm SVL, females 21.0-23.9 mm SVL); canthus rostralis distinct; dorsal skin texture smooth to slightly rugose; belly orange in life; advertisement call with duration of 0.6-0.84 s and frequency between 0.9-1.8 kHz. Descriptions of the advertisement call and tadpole are provided, as well as information on natural history.

Fecundity of the crab Callinectes ornatus Ordway, 1863 (Decapoda, Brachyura, Portunidae) from the Ubatuba region, São Paulo, Brazil

The objective of the present study was to characterize the fecundity of Callinectes ornatus from the northern coast of São Paulo, Brazil. To study the fecundity and its relationships to size, brood weight, and egg size, the ovigerous females were collected at 2-month intervals for two consecutive years (January, 1991 to November, 1992) in the Ubatuba region using a fishing boat equipped with an otter-trawl type of net. After collecting, the animals were screened, bagged, labeled, and stored frozen. Only data from 38 females carrying early stage eggs were considered. In the laboratory, the specimens were thawed at room temperature, the pleopod structure with the egg mass was removed and the eggs were carefully removed from the pleopods. The samples were then fixed in 10% formalin and stored in 70% ethanol, until the time for processing. Processing followed the method of Hines (1982, 1988). Following the frequency determination of carapace width and fecundity, mean egg number, mean volume and mean dry weight of brooded egg mass were determined for each class obtained. Data were analyzed by regressions of log-log transformations for allometric plots (Y = aX(b)) of reproductive variables versus carapace width. Carapace width was one of the main factors for the determination of fecundity, which ranged 171 570 +/- 94 634 eggs, with females of the same size class presenting a wide amplitude of variation. This supports the hypothesis that portunid females present staggered spawning, possibly presenting more than one period of reproduction within one year. The present species showed lower fecundity than the remaining portunids studied, but they did show a rapid and efficient embryonic development, presumably capable of assuring reproductive success.

Anatomical investigation of the slender catshark Schroederichthys tenuis Springer, 1966, with notes on intrageneric relationships (Chondrichthyes: Carcharhiniformes: Scyliorhinidae)

The slender catshark Schroedericthys tenuis Springer, 1966, originally described from two immature males, is redescribed on the basis of 12 specimens of both sexes, juveniles and adults (as well as the holotype and paratype). The supplementary specimens were collected off the northern coast of Brazil between Amapá and Pará states. Aspects of its external morphology, color pattern, dermal denticles, dentition, vertebral counts, and the cephalic, clasper and pectoral fin skeleton are described in detail and fully illustrated. These features are compared with those of congeneric species. Our observations support preliminary results of work in progress that S. maculatus Springer, 1966, S. tenuis and S. saurisqualus Soto, 2003 form a monophyletic group, mostly on the basis of neurocranial morphology, and that S. bivius (Smith, 1838) and S. chilensis (Guichenot, 1848) should be removed from Schroederichthys.

Ampliação da distribuição geográfica de três caranguejos majóideos (Crustacea, Decapoda, Brachyura) na costa do Estado de São Paulo, Brasil

This study reports range extensions of three species of crabs to the northern coast of the state of São Paulo. The species obtained were Inachoides forceps, Microphrys antillensis and Mithraculus sculptus. Recent new records of marine species in Brazilian waters illustrate the importance of continuous investigations on the biodiversity of subtidal rocky bottoms.
