Alpheid Shrimp

A new species of the alpheid shrimp genus Salmoneus Holthuis, 1955, probably an obligate associate of ghost shrimp burrows, is described based on material from Oman (type locality: Darsait near Muscat), Iran and the Philippines. Salmoneus durisi sp. nov. is characterised principally by both chelipeds enlarged, robust, with ventral and dorsal margins of chelae carrying long fine setae, and with minor chela fingers armed with a few large teeth on cutting edges. All specimens of Salmoneus durisi sp. nov. were collected either directly from burrows of larger decapod crustaceans with the aid of a suction pump, or by exposing burrows dug under large subtidal rocks. The Iranian specimen was found together with its presumed host, Neocallichirus calmani (Nobili, 1904). Two additional specimens from Indonesia and the Solomon Islands are tentatively assigned to S. cf. durisi sp. nov., awaiting further studies.

Alpheid Shrimp

The Indo-West Pacific alpheid shrimp genus Athanopsis Coutière, 1897 is briefly reviewed. Athanopsis platyrhynchusCoutière, 1897, the type species, is reassessed using Coutière’s illustrations and morphological notes scattered throughouthis monograph of the family Alpheidae (Coutière 1899). Athanopsis brevirostris Banner & Banner, 1981, originally de-scribed on the basis of a single immature specimen missing both chelipeds, is reported and illustrated based on fresh ma-terial from Madagascar and southern Japan. Athanopsis gotoi sp. nov. is described based on two fresh specimens fromsouthern Japan, both found associated with thalassematid echiurans, and an additional, older museum specimen from In-donesia. The colour patterns of A. brevirostris, A. gotoi sp. nov., A. saurus Anker, 2011, A. rubricinctuta Berggren, 1991,and A. australis Banner & Banner, 1982, are contrasted to facilitate their identification in the field. A morphology and colour based key to all presently known species of Athanopsis is also provided.

Important Habitat

Natural deposits of sunken wood provide an important habitat for deep-sea invertebrates. Deep-sea chitons in the primitiveorder Lepidopleurida are typically collected rarely and as single specimens. However, these animals have been recoveredin large densities associated with sunken wood in the tropical West Pacific, in groups of up to 50 individuals. Four deep-sea expeditions in the West Pacific, to the Philippines, Solomon Islands, and Vanuatu, recovered a large number of poly-placophorans. We have examined the morphology as well as the range and distribution of these species, based on the larg-est collection ever examined (more than 1300 individuals). These species show potentially adapted characters associatedwith exploitation of sunken wood as habitat, such as protruding caps on sensory shell pores (aesthetes) and large interseg-mental bristles with potential sensory function. In this study we investigated the twenty-two species recovered, includingseven newly described here (Leptochiton consimilis n. sp., L. angustidens n. sp., L. dykei n. sp., L. samadiae n. sp., L.longisetosus n. sp., L. clarki n. sp., L. schwabei n. sp.), and provide the first identification key to the 34 lepidopleuran chitons known from sunken wood worldwide.

Argostemma separatum, a new species with free stamens in star-shaped corolla from Mt. Halcon Oriental Mindoro, Philippines is here described and compared with Argostemma diversifolium, the only species of the genus with this type of flower. This species is distinct from A. diversifolium by its indumentum on stem, leaf blades and calyx, smaller leaf blades, fewer flowered inflorescences, shape of stipule and calyx, red tips on corolla lobes, and color of anthers. Based on the recent IUCN categories, the conservation status of A. separatum is Data Deficient (DD) since it was only collected at the type locality.

A New Species

Five species of decapod crustaceans, including Calliax nishiki sp. nov. (Axiidea, Eucalliacidae) and Carcinoplax longimana (de Haan), are described from the upper part of the Moeshima Silt Bed (latest Pleistocene to Holocene: ca 13,000 to 8,000 cal BP). Ten decapods, including Laticallichirus grandis (Karasawa & Goda) and Ebalia tuberculosa (A. Milne-Edwards) are described from the Moeshima Shell Bed (Holocene: ca 8,000 to 2,000 cal BP). Calliax nishiki is abundant and Carcinoplax longimana is common in the decapod assemblage of Moeshima Silt Bed. The new species of Calliax seems to have dispersed around the deep marine setting with a reducing environment. The decapod assemblage of the Moeshima Shell Bed is characterized by a predominance of L. grandis. The present record suggests that L. grandis is abundant under sandy and gravelly bottoms mixed with shells of the lower sublittoral to subtidal zones during the Quaternary.

A new species of stomatopod crustacean, Oratosquillina nordica sp. nov. is described from the Indo-West Pacific region (type locality: Taiwan). It is most similar to O. quinquedentata (Brooks, 1886), with which it has been confused. Oratosquillina quinquedendata is presently known only from the southern hemisphere, and most of its northern hemisphere records are referable to O. nordica. Records of O. quinquedentata from India and Sri Lanka require confirmation, possibly representing a third species. A key to the species of Oratosquillina is provided.

A new porcellanid crab, Polyonyx spina, is described from the Philippines and Loyalty Islands. Among the Indo-West Pacific species of the genus, the spines on the flexor margins of the meri of the ambulatory legs are found only in the new species and P. pedalis Nobili, 1905. Polyonyx spina is distinguished from P. pedalis by the shape of the carapace and third thoracic sternite, and the strength of spines on the meri of the ambulatory legs.

Abstract Comparison on the abundant material of Galearctus timidus (Holthuis, 1960) recently collected from the Philippines and Madagascar showed that there are differences in the development of carapace teeth, abdominal sculpture, pereiopods ornamentation and coloration between the specimens from these two localities. Molecular analysis also reveals high genetic divergence between the two forms. Since the type locality of G. timidus is from the Philippines, the Madagascan form is described as a new species.

Alpheid Shrimp

Three species of the alpheid shrimp genus Salmoneus Holthuis, 1955 associated with burrows of other decapod crustaceans are reported from various Indo-West Pacific localities. Salmoneus venustus sp. nov. is described based on material collected at two distant localities, Nha Trang Bay, southern Vietnam, the type locality of the new species, and the Yiti-Sifah region east of Muscat, northern Oman. Both specimens were collected with the aid of a suction pump applied to burrow entrances or mounds in muddy sand; the holotype was possibly associated with burrows of the callianassid ghost shrimp, Glypturus sp. Salmoneus venustus sp. nov. shares many characteristics with S. latirostris (Coutière, 1897), including the red banding of the pleon, but can be distinguished from S. latirostris and all other species of the genus by a unique combination of morphological characters. The large-sized Salmoneus brucei Komai, 2009 is reported from Sumba, central Indonesia, representing a significant southward extension of the species’ previously known distribution range and the first record since its original description. The callianassid ghost shrimp Lepidophthalmus cf. rosae (Nobili, 1904) is recorded as a new host of S. brucei. Finally, Salmoneus colinorum De Grave, 2004, associated with burrows of larger snapping shrimps from the Alpheus malabaricus Fabricius, 1798 species complex, is reported for the first time from Madang, Papua New Guinea, representing an eastward extension of the species’ previously known distribution range.
