A New Species

A new species of the freshwater crab genusSundathelphusaBott, 1969 (Gecarcinucidae) is described from the island of Mindanao in the southern Philippines. The Philippine Islands host the greatest species diversity of this genus, although only four species were previously known from Mindanao. The new species is most similar toS. mistio(Rathbun, 1904) andS. montanoanus(Rathbun, 1904) in the general carapace outline and leg proportions, but it can be distinguished by features of the carapace, thoracic sternum and gonopods. With this discovery, there are now 29 species ofSundathelphusaknown from the Philippines.

A New Species

The systematics of the wide-ranging southeast Asian colubrid snake Dendrelaphis caudolineatus (Gray, 1834) wasinvestigated on the basis of multivariate analyses of morphological and coloration data for 131 museum specimensrepresenting 28 geographically isolated populations. The results demonstrate that the current taxonomy of D.caudolineatus underestimates species diversity in the Philippines. The following revisions are implemented. 1)Populations from the Philippine island Palawan and adjacent islands currently referred to D. c. caudolineatus (Gray, 1834)are described as a new species, D. levitoni sp. nov. 2) Populations from the Philippine islands Negros, Panay, Mindoroand Masbate, currently assigned to D. c. terrificus (Peters, 1872) and D. c. luzonensis Leviton, 1961 are referred to D.fuliginosus Griffin 1909, which is revalidated. 3) Populations from the southern Philippine islands Basilan, Mindanao,Cebu, Bohol, Leyte, Samar, Polillo, Kalotkot, Catanduanes as well as Southeast Luzon currently referred to D. c. terrificus(Peters, 1872) are referred to D. philippinensis Günther, 1879 which is revalidated. 4) The population from Sulawesi isreferred to D. terrificus (Peters, 1872). Currently regarded as a polytypic species composed of five subspecies, D.caudolineatus is here considered to be a monophyletic group comprising eight species. The distributions of these eightspecies correspond largely with aggregate island complexes formed during periods of reduced sea level during the Pleistocene. However, some deviations indicate post-Pleistocene dispersals across sea barriers.

A New Species

Although Gastrochilus Don (1825:32) is a small genus, its generic and interspecific relationships are still not well understood (Seidenfaden1988, Tsi 1996, Pridgeon et al. 2014, Zou et al. 2015). It comprises 64 species collectively distributed from China, India and Sri Lanka through eastern Asia and southern Japan to Indonesia and the Philippines (Kumar et al. 2014, Govaerts et al. 2015, Raskoti 2016). China is the centre of species diversity for the genus, which contains 39 species, 19 of which are believed to be endemic (Tsi 1999, Chen et al. 2009, Yi et al. 2012, Kumar et al. 2014). During our field investigation in southeastern Yunnan, two unusual species of this genus were discovered. After undertaking a comprehensive literature and herbarium review, these two species were identified as G. sect. Gastrochilus Don (1825: 32), which is characterized by stout stem with large cauline leaves. One is a new record for China, and the other is the new species.

Abstract Among Antarctic amphipods of the genus Eusirus, a highly distinctive clade of giant species is characterized by a dorsal, blade-shaped tooth on pereionites 5–7 and pleonites 1–3. This lineage, herein named ‘crested Eusirus’, includes two potential species complexes, the Eusirus perdentatus and Eusirus giganteus complexes, in addition to the more distinctive Eusirus propeperdentatus. Molecular phylogenies and statistical parsimony networks (COI, CytB and ITS2) of crested Eusirus are herein reconstructed. This study aims to formally revise species diversity within crested Eusirus by applying several species delimitation methods (Bayesian implementation of the Poisson tree processes model, general mixed Yule coalescent, multi-rate Poisson tree processes and automatic barcode gap discovery) on the resulting phylogenies. In addition, results from the DNA-based methods are benchmarked against a detailed morphological analysis of all available specimens of the E. perdentatus complex. Our results indicate that species diversity of crested Eusirus is underestimated. Overall, DNA-based methods suggest that the E. perdentatus complex is composed of three putative species and that the E. giganteus complex includes four or five putative species. The morphological analysis of available specimens from the E. perdentatus complex corroborates molecular results by identifying two differentiable species, the genuine E. perdentatus and a new species, herein described as Eusirus pontomedon sp. nov.

A New Species

The Atlantic Forest of Brazil includes one of the highest species diversity and endemism in the planet, representing a priority for biodiversity conservation. A new species of Anemopaegma from the Atlantic Forest of Brazil is here described, illustrated and compared to its closest relatives. Anemopaegma nebulosum Firetti-Leggieri & L.G. Lohmann has been traditionally treated as a morph of Anemopaegma prostratum; however, additional morphological and anatomical studies indicated that A. nebulosum differs significantly from A. prostratum and is best treated as a separate species. More specifically, A. nebulosum is characterized by elliptic and coriaceous leaflets (vs. ovate to orbicular and membranaceous in A. prostratum), smaller leaflet blades (3.6–5.5 x 2.0–3.0 cm vs. 6.7–13.0 x 4.2–8.4 cm in A. prostratum), orbicular prophylls of the axillary buds (vs. no prophylls in A. prostratum), solitary flowers (vs. multi-flowered axillary racemes in A. prostratum) and a gibbous corolla (vs. infundibuliform corollas in A. prostratum). In addition, A. nebulosum differs from A. prostratum anatomically in having thicker leaflet blades composed of two to four layers of palisade parenchyma (vs. one to three layers in A. prostratum), and seven to eight layers in the spongy parenchyma (vs. six to eight layers in A. prostratum). A key for the identification of all species of Anemopaegma from the Atlantic Forest of Brazil is presented.

A New Species

Mangroves create unique ecological environments, furnishing a habitat opportunity for many species. The majority of published information on mangrove sponges comes from the Caribbean while few data are available from Indo-Pacific mangrove sponges. In general, species diversity of sponges in mangroves is lower than adjacent subtidal habitats in both the Caribbean and Indo-Pacific. The aim of this study is to report the first data about sponge species diversity of two mangrove forests from Bangka Island (North Sulawesi, Indonesia) and to describe a new sponge species associated with the mangroves. The survey found 19 species, belonging to 11 families and 15 genera; the samples were collected on mangrove trunks, on the roots or on the surrounding bottom. The majority of the species are typical of coral reef but two of them have been previously found only in lagoons or in mangrove habitats. These new data enlarge our knowledge about Indonesian sponges diversity and suggest the urgency to consider Indonesian mangroves as an important but underestimated element in coral reef ecological dynamics.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.
