A New Species

A new species of semi-terrestrial sesarmid crab of the genus Geosesarma De Man, 1892, is described from central Taiwan. Geosesarmamirumsp. nov. is distinct in possessing a strong transverse crest on the inner surface of the male chela and a diagnostic male first gonopod which is relatively long and stout, with the distal chitinous part broad and spatuliform. Like most Geosesarma species, G.mirumsp. nov. has large eggs and direct development, contrasting with the only other species known from Taiwan, G.hednon Ng, Liu and Schubart, 2004, which has small eggs and planktotrophic larvae.

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

A new species, Diopatra marocensis, is described from the fine sand Abra alba community, Sidi Boulbra, south Moroccan Atlantic coast. The new species is a member of the D. cuprea complex and is characterized by having crescentic nuchal grooves, short ceratophores, a short branchiate region, four pairs of modified parapodia with bidentate pseudocompound hooks, pectinate setae with 11–20 teeth, limbate setae with conspicuously serrated shelf, and subacicular hooks from setiger 13–15. Eggs of Diopatra marocensis sp. nov. are deposited in the parental tube, where they undergo direct development and remain until the young consist of 32–34 setigers.

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.

It differs fromN. brachylepadoformisNewman, 1989 by the apical end of the inner surface of the movable scutum being in a pocket-form, with a longitudinal groove upwards, and without median ridges; the adductor ridge (or myophore) of the fixed scutum stout and the inner distal part of the scutum without longitudinal ridge.

A New Species

We describe a new species of microhylid frog of the genus Chiasmocleis from the upper Amazon basin of Peru (area of Iquitos, Departamento Loreto). The new species is characterized by small size, distinct reduction of fingers I and IV and the presence of large unpigmented eggs in the oviducts. The latter character is so far unknown in the recognized species of the genus and may indicate the presence of a terrestrial reproductive mode. The generic placement of the new species is discussed.

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 Thrixspermum indicum is described and illustrated from Northeast India. It is allied to T. carnosum, T. muscaeflorum and T. trichoglottis but quite distinct from all these species in having broadly triangular lateral lobes of lip with acute incurved tips and absence of hairs on the inner surface, margins of mid-lobe and side lobes of lip.

A new species of the genus Beebeomyia Curran found in the northern coastal region of the state of Pernambuco, northeastern Brazil is described and illustrated, including characteristics of the male and female terminalia, third instar larva and puparium. This new species is only the second record for the genus in Brazil and broadens its occurrence to the Atlantic Forest ecoregion. Beebeomyia taccarivora sp. nov. is straightforwardly distinguishable from all other known species of Beebeomyia for exhibiting an entirely yellowish orange thorax with a central brown-colored stripe on the scutum, and a brownish orange abdomen with a central brown stripe on tergites 1–4. Similarly to what had been previously described for congenerics, female B. taccarivora flies exclusively use the inflorescences of their host plant, Taccarum ulei, as oviposition and brooding sites. Developing larvae feed on living floral tissue and pollen, and pupariation occurs within the inner surface of the spathe.
