“…Charybdis goaensis which were found in Goa, India [3], morphologically have smaller size compare to our specimens from West Coast of North Sumatera, both in male and female. The average of Carapace Width (CW) for males and females of Charybdis goaensis from Goa were 27,83 mm and 25.52 mm respectively, while our specimens have 28,13 mm in males and 33,55 mm in females.…”

“…The specimens were deposited in Laboratory of Animals Biosystematic, Departement of Biology, IPB University. Identification was referring to Padate et al [3], as the first describer of Charybdis goaensis. Information about the measure was available, Carapace Width (CW) and Carapace Length (CL).…”

“…Charybdis is characterized by its carapace which has anterior border more narrow than the posterior border and has six or seven anterolateral teeth [2]. Charybdis can be found in the shallow coastal environment, shallow nearshore water, and deep sea, while Charybdis goaensis which was reported from Goa, west coast India, was collected using trawling in the estuarine and offshore areas of Goa [3].…”

The first report of Charybdis goaensis Padate, Rivonker, Anil, Sawant & Krishnamurthy, 2010 was from Goa, India in 2010 year. Its occurrence in Indonesia is the second report in the world. The samples were harvested by a fisherman in Sibolga city and Natal district-Mandailing Natal Regency, North Sumatera. We recorded three males and ten females of Charybdis goaensis, which consists of juveniles and ovigerous females. Both sampling locations are in one coastline in west coast Sumatera which faces directly to the Indian Ocean. We assumed that the dispersal of this species through the Indian Ocean is at their larval phase.

“…They are used in the transfer of spermatophores into the female seminal receptacles during mating (Bauer, 1986). They are of particular interest in the brachyuran male reproductive system, because they are morphologically diverse yet taxonomically very conservative, and hence provide valuable taxonomic and phylogenetic information (Beninger et al, 1991;Wee et al, 1995; * Corresponding author; e-mail: micaelavallina@conicet.gov.ar Goldstein and Dupré, 2010;Lai et al, 2010;Padate et al, 2010;Sal Moyano et al, 2011a;Guinot et al, 2013). The particular shapes of the gonopods and the presence of microstructures, suggest the hypothesis that they have different roles during copulation (mechanism of insertion, function of the setae) (Sal Moyano et al, 2011a).…”

A B S T R A C TOvalipes trimaculatus (de Haan, 1833) is a commercial species captured in the Mar del Plata coast, Argentina. However, no studies were conducted in order to study its population features neither its reproductive biology. The morphometric and physiological maturity of both sexes, the histology of the female seminal receptacle and ovary, and the ultrastructure of the male gonopods were studied in the present paper. In females, morphometric maturity (44.6 mm of carapace width, CW) was acquired prior to physiological maturity (54.6 mm CW). By contrast, in males, physiological maturity (46.6 mm CW) was acquired prior to morphometric maturity (52.3 mm CW). The ovary is connected to the dorsal part of the seminal receptacle. Neither Spermatophores, nor sperm packets were found inside the seminal receptacle; instead free spermatozoids were observed indicating that sperm from different males is probably mixed favoring sperm competition. The ultrastructure of the male gonopods was similar to the described for other Brachyura. Different types of setae and the presence of internal rosette glands were described and probable functions were suggested.

“…The near-shore waters (down to 25 m depth) off Goa, west coast of India support a wide array of demersal fauna (Ansari et al 1995;Padate et al 2010aPadate et al , 2010bHegde & Rivonker 2013). Intensive bottom trawling surveys to assess the diversity and community structure of the demersal fauna from November 2010 to January 2013 revealed three specimens of hexapodid crabs that could not be identified to species level.…”

A new species of hexapodid crab, Hexapus bidentatus sp. nov. is described from Goa, west coast of India. The new species differs from its closest congener, H. estuarinus in possessing more slender chelipeds, two large basal teeth on the dactylus and two small basal teeth on the pollex of the larger cheliped, a smaller cheliped with more or less straight fingers with a triangular gap between them, and the tip of the gonopod (G1) with nine spines on the outer border. Additionally, an updated description of H. estuarinus based on an examination of the holotype and another specimen collected from Goa is provided. A comparative analysis of H. sexpes, H. estuarinus and the new species is made. A key to all the five valid species of the genus Hexapus, including the new species, is provided.
