Although species in this genus have a very conservative external mor- phology, the new species can be differentiated from its closest congeners by the characteristic form of the male first pleopod. RÉSUMÉ Une nouvelle espèce de crabe d’eau douce Potamidae, Thaipotamon holthuisi sp. nov., est décrite de Thailande. Bien que les espèces de ce genre aient une morphologie externe très constante, la nouvelle espèce peut se différencier de ses plus proches congénères par la forme caractéristique du premier pléopode male. INTRODUCTION Potamid freshwater crabs of the genus Thaipotamon Ng & Naiyanetr, 1993, are characterised morphologically by a smooth, swollen carapace; third maxillipeds with a distinctly curved exopod bearing a short but well-developed flagellum; broadly triangular male abdomen; long, slender ambulatory dactyli: and the male first pleopods with a “hook-like” terminal segment bearing a very 3) e-mail: [email protected] 4) Corresponding author; e-mail: [email protected] © Koninklijke Brill NV, Leiden, 2010 Studies on Malacostraca: 529-534 530 CRM 014 – Fransen et al. (eds.), LIPKE BIJDELEY HOLTHUIS MEMORIAL VOLUME high and broad dorsal flap (Ng & Naiyanetr, 1993). Thaipotamon species are terrestrial crabs, being often found on the forest floor away from surface water (Yeo et al., 2008). The genus includes six species to date: T. chulabhorn Naiyanetr, 1993, T. dansai Ng & Naiyanetr, 1993, T. lomkao Ng & Naiyanetr, 1993 [type species], T. smitinandi (Naiyanetr & Türkay, 1984), T. siamense (A. Milne-Edwards, 1869), and T. varoonphornae Ng & Naiyanetr, 1993 (see Ng et al., 2008). One taxon, Megacephalomon kittikooni (Yeo & Naiyanetr, 1999), originally described under Thaipotamon, was recently reassigned to its own genus by Yeo & Ng (2007). The present study describes a new species from Thailand, here named Thaipotamon holthuisi sp. nov., bringing the number of species in the genus to seven. The following abbreviations are used: G1 and G2 for the male first and second pleopods (gonopods), respectively. Measurements, in millimetres, are of carapace width and length, respectively. Terminology used in the descriptive accounts essentially follows Ng (1988). Material examined is deposited in the Chulalongkorn University Natural History Museum (CUMZ), Bangkok, Thailand, the Zoological Reference Collection (ZRC) of the Raffles Museum of Biodiversity Research, National University of Singapore; and Muséum national d’Histoire naturelle (MNHN), Paris, France.

It can be distinguished from congeners by the following characters: male first gonopods bent inward at about 45 at base of terminal segment, carapace regions distinct and rugged and the female vulva opening inwards and downwards.

ABSTRACT This article reviews the current knowledge of primary freshwater crabs (Decapoda, Brachyura) in Iranian inland waters, with the purpose of classifying the exact number of species, the threat sta- tus, and their distribution and diversity. Previous studies have reported that Iranian inland waters have eight freshwater crab species and there was no accurate information on the distribution of freshwater crab species in Iran. This review article describes that an additional six freshwater crab species, Potamon gedrosianum, P. magnum, P. mesopotamicum, P. ilam, Sodhiana blanfordi, and S. iranica, are also present in Iran. Therefore, there are 14 freshwater crab species currently known in Iran, which belong to two families (Gecarcinucidae and Potamidae). The genus Potamon is rep- resented by 11 species, and the genus Sodhiana is represented by 3 species (found in south and south east of Iran). In addition, this review presents a distribution map and the possible threats for each species.

L. NG Department of Zoology, National University of Singapore, Kent Ridge, Singapore 0511, Republic of Singapore and Masatsune TAKEDA Department of Zoology, National Science Museum, Shinjuku, Tokyo 169, Japan Abstract Freshwater crabs of the family Potamidae (sensu NG, 1988) from the Philippines are studied on the basis of collections in the National Science Museum, Tokyo, and the National Museum of the Philippines. Three new genera, Ovitamon, Insulamon and Mindoron, are established, and five new species (O. arcanum, O. toma- culum, Insulamon unicorn, Mindoron pala, Isolapotamon spathd) are described. A key to the Philippine potamid genera is given. The freshwater crab fauna of the PhiHppines is poorly known. Although the archipelago has more than 7,000 islands, only 20 wholly freshwater species in three families, Potamidae ORTMANN, 1896, Parathelphusidae ALCOCK, 1910 (both sensu NG, 1988), and Grapsidae MCLEAY, 1838 {partim) have been described. Most are from the largest island, Luzon. In 1985, the second author made extensive collections of freshwater crabs in the Philippines under the financial support of the Monbusho International Scientific Research Program of the Japanese Government. The freshwater crabs were collected from many parts of Luzon, Mindoro, Cebu, Panay, Mindanao and Palawan during a period of two months. In the serial reports of the present study, the specimens at hand will be recorded together with the additional specimens received from Drs. S. UENO and H.

Morphological comparisons between Italian, Maltese and North African populations are discussed. Earlier literature is evaluated and sections on biogeography, distribution and biology of the new subspecies are also given.

Le popolazioni maltesi vengono confrontate con quelle italiane e nordafricane. Viene discussa la letteratura e forniti elementi biogeografici e biologici. Introduction In the Maltese language the freshwater crab or river crab {Potamon sp.) has a common name and is referred to as Qabru (plural: Qwabar). Thanks to this common name it is possible to know the first probable reference, in the literature, to the freshwater crab in Malta. In 1647 the Maltese historian Fra Giovanni Francesco ABELA, while describing Malta, indicated the locality "Marsa piccola" with the words "Marsa picciola detta Sciat el Kuabar, cioè lido di grand" (ABELA 1647).
