A New Species

Two distinct morphotypes of sand bubbler crab (Dotillidae) from eastern India were assigned to Dotilla intermedia De Man, 1888, by British carcinologist, Stanley Kemp in 1919, due to similarities in the areolation of the carapace and the occurrence of these two forms in the same locality. Kemp, however, also illustrated the differences in the morphology of the male thoracic sternums, chelae, and first gonopods and, accordingly, divided D. intermedia into two subcategories which he called the “high form” and the “low form”. The recent designation of a lectotype for D. intermedia, which corresponds with Kemp’s “high form”, makes it possible to recognize the “low form” as a distinct and new species, D. fraternalis n. sp., which is described here. Furthermore, Kemp’s synonymization of Dotilla clepsydrodactylus Alcock, 1900, under Dotilla intermedia is affirmed here after examination of the surviving syntypes. A lectotype is selected to stabilize the taxonomy of this species.

A New Species

The identity of the majid species of Paramaya De Haan, 1837, in the Indian Ocean is clarified with the collection of fresh specimens from the Bay of Bengal. Previously identified as P.spinigera (De Haan, 1837) which is known only from Japan, Taiwan, and Korea, the material from eastern India is here referred to a new species, P.mulli sp. n. The new species can easily be distinguished from all congeners by its relatively shorter pseudorostral and carapace spines, more swollen branchial regions, distinctly granulated male thoracic sternum, and the G1 is not prominently curved with the dorsal projection on the sub distal part short and the tip rounded.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

A new species of megophryid frog of the genus Leptolalax is described from the Tamdil wetlands of Mizoram State, north-eastern India. L. tamdil new species, is compared with congeners from India and other parts of south-east Asia. The new species is diagnosable in showing the following combination of characters: SVL 32.3 mm in the only male and 31.8 mm in the only female known; dorsum tuberculate; eyelids with tubercles; tympanum and supratympanic fold distinct; supratympanic fold extending to posterior edge of tympanum; macroglands, including preaxillary, pectoral, femoral and ventrolateral glands present; Finger II > I; toe tips not dilated, bearing dermal fringes; relatively long hind limbs, with heels in contact when limbs are held perpendicular to body; dorsum with dark blotches; flanks with small dark blotches; dark tympanic mask present; venter pale; labial bars present and limbs with dark cross-bars.

A New Species

A new species of the genus Thalassironus de Man, 1889 was discovered during several surveys of the offshore marine ecosystem in Korea. This new species belonging to the family Ironidae, Thalassironus koreanus sp. nov., shares general morphological traits of the genus such as an optically smooth cuticle, buccal cavity consisting of two parts with three movable teeth and thick cuticularized walls, six rounded lips with ten cephalic setae, slit-like amphid and short conical tail with caudal glands present. The new species is most closely related to T. bohaiensis, first discovered in the Bohai Sea, in terms of body ratio (a, b, c, c’) and general morphology, but differs by its generally longer and larger body structures, cervical setae at the level of the buccal cavity, paired somatic setae distributed along the body, and longer/larger spicule. A description of Thalassironus koreanus sp. nov., diagnosis of the genus, emended pictorial key for the genus and discussion of important characteristics for the genus is provided.

A New Species

Freshwater prawns do not only have economic importance in hydroponics and fisheries for food purposes, but also recently receive increasing attention in aquarium trade (Karge & Klotz 2007). An examination of some prawns imported as ‘ornamental shrimps’ from Cooch Behar, East Bengal, India to Europe revealed that they belong to a hitherto undescribed species of the genus Macrobrachium and are described here in detail. The new species belong to the group of specimen with large eggs, indicating abbreviated or direct larval development in freshwater, occurring in inland river systems (Tiwari 1955b). Morphological M. agwi nov.sp. is most similar to M. kempi (Tiwari, 1947) first described from Chittagong, Bangladesh, M. altifrons altifrons (Henderson, 1893) from Northern India and Nepal and M. hendersoni (De Man, 1906) known from hill streams in East India and Myanmar. Though the proposed new species can be distinguished from M. kempi by lacking a dense fur of setae on the lower margin of the propodus of male large cheliped, from M. altifrons by the shape and armature of second chelae and from M. hendersoni by lacking longitudinal groves covered with fine hairs on fingers of second chelipeds.

A new species of the snapping shrimp genus Alpheus Fabricius, 1798, A. longipalma, is described and illustrated on the basis of material from Kagoshima Bay, Kyushu, Japan. It is referred to the A. brevirostris (Olivier, 1811) species group, and appears closest to A. macroskeles Alcock & Anderson, 1894, known with certainty from the Bay of Bengal and Andaman Sea, and A. talismani Coutière, 1898 from the eastern Atlantic. The greatly elongate minor cheliped in males, being subequal to or longer than the major cheliped with proportionally shorter dactylus distinguish the new species from A. macroskeles. The less elongate antennular peduncle and better-developed, rounded distal lamella of the antennal scaphocerite differentiate the new species from A. talismani. All specimens of the new species were trawled from depths greater than 200 m.

On the taxonomy of Palaemon javanicus Heller, 1862, and Palaemon sundaicus Heller, 1862, with description of a new species of Macrobrachium Bate, 1868 (Crustacea: Decapoda: Caridea: Palaemonidae) from Southeast Asia

Subjective Synonym

Re-examination of the type material of Palaemon javanicus Heller, 1862, shows that the current concept of the species is wrong. This species is in fact a senior subjective synonym of a widespread Southeast Asian species now known as Macrobrachium trompii (De Man, 1898). The species now commonly referred to as “Macrobrachium javanicum” following De Man (1879) from Southeast Asia is in fact, undescribed, and is here named Macrobrachium duri spec. nov. Macrobrachium duri spec. nov. can easily be distinguished from M. javanicum sensu stricto by the presence of a small triangular median process on the fourth thoracic sternite, possessing spinulate third to fifth pereiopods, having both second periopods covered with spines and few scattered short stiff setae, and the eggs been small and numerous. To add to the confusion, Palaemon javanicus Heller, 1862, is also synonymous with P. sundaicus Heller, 1862, and both were described by Heller (1862) in the same paper, making both names simultaneously available. As first revisors, we hereby choose P. sundaicus Heller, 1862, to have priority over P. javanicus Heller, 1862, when the two names are considered to be synonyms. Palaemon sundaicus Heller, 1862, is therefore also the senior synonym of Macrobrachium trompii (De Man, 1898).
