[Paleontology • 2017] Moabosaurus utahensis • A New Sauropod From The Early Cretaceous (Aptian) of North America

Moabosaurus utahensis 
Britt, Scheetz, Whiting & Wilhite, 2017

 The Early Cretaceous was a time of dramatic change for sauropod dinosaurs in North America. Between the Late Jurassic-aged Morrison Formation and overlying Early Cretaceous strata, there was a dramatic decline in sauropod diversity. Here, we describe a new sauropod that adds to the diversity of the Early Cretaceous, from strata that can be no older than the early Aptian, (125 Ma) some 25 million years younger than the Morrison Formation. 

Moabosaurus utahensis, n. gen., n. sp., is diagnosed in part by the following suite of characters: axially thin ventral basioccipital with posteriorly sweeping basal tubera; low-spined cervical vertebrae with neural spines that range from shallowly notched on anterior cervical vertebrae to shallow, but widely notched on middle and some posterior cervical vertebrae; posterior cervical and anterior dorsal neural spines with extremely low, axially thin, laterally wide ridges at the level of the zygapophyses; some cervical ribs with bifid posterior shafts; anterior and posterior caudal vertebrae with strongly procoelous centra, middle caudal vertebrae with mildly procoelous centra, and distal caudal vertebrae with moderately-to-strongly procoelous centra.

 To determine the phylogenetic position of Moabosaurus we utilized three different datasets and performed four analyses. All results are in agreement that Moabosaurus is a neosauropod. The two most resolved trees indicate it is a macronarian, specifically a basal titanosauriform. The thick-walled, camerate presacral vertebrae and other characters, however, preclude a more highly nested position of Moabosaurus within either Titanosauriformes, which is characterized by moderately camellate presacral vertebrae, or Somphospondyli, which is characterized by fully camellate presacral vertebrae, including the neural arches. Incorporation of these and other characters, particularly those shared with Turiasaurus and Tendaguria, into phylogenetic analyses will help resolve the interrelationships of Moabosaurus with other neosauropods.

[Ichthyology • 2017] Amblygaster indiana • A New Species of Clupeid Fish (Clupeiformes: Clupeidae), off Eraviputhenthurai, West Coast of India

Amblygaster indiana  
Mary, Balasubramanian, Selvaraju & Shiny, 2017
   DOI:  10.11646/zootaxa.4247.4.7 


A new species, Amblygaster indiana sp. nov., is described from 12 specimens collected from fish landing centers and fish markets at Eraviputhenthurai, west coast of India. The new species can be differentiated from all other species of Amblygaster by its larger size and very deep body, 8 circular-shaped pre-pelvic scutes, different gill rakers counts, large eyes, 40 lateral scales, and peculiar gap between the left and right frontoparietal striae on the top of the head. The new species has been seasonally captured with A. sirm in Eraviputhenthurai and also other coastal waters of the south west coast of India. The proportions of A. indiana sp. nov. and A. sirm in fish catches are approximately 1 to 20. Gillnets and shore seines are used to catch Amblygaster spp. along the Eraviputhenthurai coast and along the coastal zones of south west coasts of India.

[Herpetology • 2017] Distinction of Gracixalus carinensis from Vietnam and Myanmar, with Description of A New Species, Gracixalus sapaensis, from northwestern Vietnam

Gracixalus sapaensis  Matsui, Ohler, Eto & Tao, 2017

Figure 3. Dorsal (A) and dorsolateral (B) views of male holotype (MNHN 1999. 5961) of Gracixalus sapaensis sp. nov. in life.

Gracixalus carinensis was originally described from Myanmar, but samples of the species reported in molecular phylogenetic works were all from Vietnam, far apart from the type locality. Moreover, the voucher specimens used for sequencing seem to have never been critically studied. We newly sequenced specimens from Vietnam and also closely examined morphology of vouchers. As a result, we confirmed that samples treated under this name from Vietnam constitute a single species. Although no molecular data are available for topotypic samples from Myanmar, detailed morphological comparisons revealed that samples from Vietnam are constantly separated from the topotypic samples of G. carinensis by much poorly developed toe webbing. We thus consider the Vietnamese samples as an undescribed species and describe them as Gracixalus sapaensis sp. nov.

Etymology. The specific epithet is derived from Sa Pa, a district in Lao Cai Province, northern Vietnam, where the new species occurs.

Range. Known only from northwestern Vietnam (fig. 5): Lai Chau, Lao Cai and Dak Lak (Nguyen et al., 2009, as Aquixalus). The known localities vary from 1250-2340 m in altitude. 

Natural history. Ohler et al. (2000) reported the new species to occur at all the vegetation types they classified (agriculture, scrub, submontane forest, and montane forest) from 1260-2020 m a.s.l. on Fan Si Pan mountains. Specimens were usually found sitting on leaves, rarely branches, up to 2 m from the ground, in the vicinity of mountain streams (median distance observed 3 m). They also reported the new species (as Philautus carinensis) to breed mainly in October-November unlike Ph. odontotarsus (now Kurixalus), and Ph. jinxiuensis and Ph. gracilipes (both now Gracixalus) that breed in July.

[Fungi • 2017] Tricholoma highlandense & T. sinopardinum • New Species in the Tricholoma pardinum Complex from Eastern Himalaya

Tricholoma sinopardinum 
  Zhu L Yang, X.X. Ding, G. Kost & Rexer


Species of Tricholoma sect. Pardinicutis (Singer) Bon are relatively easily recognizable even in the field, and the type species of section, T. pardinum (Pers.) Quél., was reported from the eastern Himalaya and adjacent areas. However, such reports were largely based on superficially similar morphology. In this study, we have generated DNA sequences of samples from southwestern China, and found that there are molecular discrepancies between the Chinese collections and European ones. Further detailed morphological analyses indicated the two independent new species occur in southwestern China, one in subtropical coniferous forests mixed with fagaceous plants between 2400 and 2800 m altitude, the other in subalpine dark coniferous forests between 3300 and 4100 m altitude. Consequently, two new species, namely, Tricholoma highlandense and T. sinopardinum, are described and illustrated.

Two new species of hydroids, Eudendrium bleakneyi and Halecium praeparvum, are described from the Bay of Fundy. Fourteen others, Tubularia acadiae Petersen, 1990, Coryne pusilla Gaertner, 1774, Sarsia lovenii (M. Sars, 1846), Zanclea implexa (Alder, 1856), Corydendrium dispar Kramp, 1935, Rhizogeton fusiformis L. Agassiz, 1862, Bougainvillia muscus (Allman, 1863), Rhizorhagium roseum M. Sars, in G.O. Sars, 1874, Hydractinia symbiolongicarpus Buss & Yund, 1989, Eudendrium vaginatum Allman, 1863, Tiaropsis multicirrata (M. Sars, 1835), Obelia bidentata S.F. Clark, 1875, Halecium marsupiale Bergh, 1887, and Sertularella gigantea Hincks, 1874, are reported, with collection data, for the first time from the bay. All but Coryne pusilla, Rhizorhagium roseum, Eudendrium vaginatum, and Sertularella gigantea are also new to Atlantic Canada, while Zanclea implexa, Corydendrium dispar, and Halecium marsupiale are reported for the first time in the western North Atlantic. Two of those species, Hydractinia symbiolongicarpus and Obelia bidentata, are disjunct in distribution, with core populations occurring in warmer waters to the south of Cape Cod, Massachusetts. Both were discovered in Minas Basin, a hydrographically distinct embayment where surface water temperatures are much warmer during summer than in the perpetually cold lower Bay of Fundy. Rhizorhagium roseum and the subfamily Rhizorhagiinae are transferred from family Bougainvilliidae Lütken, 1850 to Pandeidae Haeckel, 1879. An annotated checklist of hydroids from the Fundy region, based on previously published reports and on new records of species, is added as an appendix. Included in the checklist are 43 species of anthoathecates and 75 species of leptothecates, referable to 30 families and 56 genera. Families with the most species were Sertulariidae (23), Haleciidae (13), Eudendriidae (11), and Obeliidae (10). Biogeographically, the aggregate hydroid fauna of the bay conforms with that occurring in other parts of the Western Atlantic Boreal Region. Halecium permodicum is proposed as a replacement name for Halecium minor Fraser, 1935, an invalid junior homonym of H. minor Pictet, 1893.

[Botany • 2017] Etlingera frederikii • A New Species of Etlingera (Zingiberaceae) from Bougainville Island, Papua New Guinea

Etlingera frederikii A.D.Poulsen

A new species, Etlingera frederikii, is described and illustrated, and is the first record of the genus in the Bougainville Region. Etlingera frederikii and E. cevuga, which occurs in Fiji and Samoa, are the two most easterly species in the distribution range of the genus. The new species differs from Etlingera cevuga in its much larger leaves, with a conspicuously silky-haired band on the ligule; the smaller, narrowly ovoid to cylindrical inflorescence with pale brown bracts (not hemiglobose with reddish brown bracts); and fewer, smaller flowers.

Etlingera frederikii A.D.Poulsen, sp. nov. 

Etymology. Named in honour of H.R.H. Frederik, Crown Prince of Denmark, who was the patron of the Danish Expedition Fund that planned and executed the Galathea 3 circumnavigation during which this new species was discovered. The Crown Prince has himself participated in expeditions to Central China and Northeast Greenland and has also supported an expedition to Borneo in 2002 led by the first author. 

Distribution. Bougainville Island. So far, documented only from the type locality in ridge forest at 850 m. It is likely to occur naturally on the neighbouring island to the south-east, Choiseul, in the Solomon Islands. A cultivated plant with a dried-up inflorescence in a garden in Buka Town, Buka Island (just north of Bougainville Island) is very likely of the same species.

Vernacular name. Rurutate (Rotokas language). Uses not known.

[Mammalogy • 2017] Sturnira adrianae • A New Polytypic Species of Yellow-shouldered Bats, Genus Sturnira (Chiroptera: Phyllostomidae), from the Andean and Coastal Mountain Systems of Venezuela and Colombia

Sturnira adrianae adrianae

Sturnira is the most speciose genus of New World leaf-nosed bats (Phyllostomidae). We name Sturnira adrianae, new species. This taxon is born polytypic, divided into a larger subspecies (S. a. adrianae) widespread in the mountains of northern and western Venezuela, and northern Colombia, and a smaller subspecies (S. a. caripana) endemic to the mountains of northeastern Venezuela. The new species inhabits evergreen, deciduous, and cloud forests at mainly medium (1000–2000 m) elevations. It has long been confused with S. ludovici, but it is more closely related to S. oporaphilum. It can be distinguished from other species of Sturnira by genetic data, and based on discrete and continuously varying characters. Within the genus, the new species belongs to a clade that also includes S. oporaphilum, S. ludovici, S. hondurensis, and S. burtonlimi. The larger new subspecies is the largest member of this clade. The two new subspecies are the most sexually dimorphic members of this clade. The smaller new subspecies is restricted to small mountain systems undergoing severe deforestation processes, therefore can be assigned to the Vulnerable (VU) conservation category of the International Union for Conservation of Nature (IUCN).

• Sturnira adrianae new species 
• Sturnira adrianae adrianae new subspecies 
Adriana’s Yellow-shouldered Bat 
Murciélago de Charreteras de Adriana

Diagnosis. Epaulettes (yellow shoulders) present. Lower molars with continuous lingual cusps. All four lower incisors well developed, bilobed. Upper middle incisor long, bilobed, pointed, strikingly protrudent, tip laterally diverging. Lower canine long, narrow. Upper premolars broad and long in labial view. Molars with no gaps between them. Zygomatic arch complete, not bowed outwards. Occiput low. Preorbital frontal ridges well developed. Foramen ovale touching the caudal pterygoid process.

 Distribution. Known from all the Andean and coastal mountain systems of Venezuela, except those east of the Unare Depression. Presumably, also distributed throughout the Cordillera Oriental in Colombia ..... 

Etymology. The epithet adrianae, a feminine noun in the genitive case, is dedicated to the memory of the Colombian-Venezuelan bat biologist, Adriana Ruiz, 1971–2012. Adriana was a charismatic, imaginative, and dedicated colleague. She published 14 papers and book chapters. Owing to her untimely departure, much of her most valuable research was left unpublished. Adriana had a particularly keen interest in species of Sturnira. We are privileged to name after her a member of the genus wandering in the environments in which she so joyfully conducted much of her field work.

• Sturnira adrianae caripana new subspecies 
Caripe Yellow-shouldered Bat 
Murciélago de Charreteras de Caripe
Diagnosis. Identical to that of S. a. adrianae, except for: 1) upper premolars narrower and shorter in labial view; 2) preorbital frontal ridges little developed; 3) foramen ovale not touching the caudal pterygoid process.

Distribution (Fig. 1). Known from four localities in the Turimiquire Massiff, and from two localities in the neighboring Paria Peninsula (Appendix). Presumably, endemic to the mountain ranges of northeastern Venezuela, east of the Unare Depression. 

Etymology. The epithet caripana [Carip(e) + -ana], a feminine adjectival toponym, is derived from Caripe, a town near the type locality made known to science in the book “Travels to the Equinoctial Regions of America, During the Years 1799–1804”, of the famous German explorer and naturalist Alexander von Humboldt.

[Botany • 2017] Sabal antillensis • A New Palmetto Species (Arecaceae) from the Leeward Antilles

Sabal antillensis M.P.Griff.


A new species of palmetto, Sabal antillensis, native to Curaçao and Bonaire, is described and illustrated. The new species is characterized by a pachycaulous habit, a compact crown of leaves, large seeds, and frequent fiber bundles in leaflet transection. Details on history, morphology, distribution, habitat, and conservation status are provided.

Sabal antillensis M.P.Griff., sp. nov.

Diagnosis:— This new species is most similar to Sabal causiarum in leaf morphology and inflorescence structure, but differs in the pachycaul habit, the petioles less than half the total leaf length giving a distinctive densely foliated crown, the smaller and less persistent ligules, the more divided leaf segments and leaf segment apices, the frequent adaxial fiber bundles between most secondary minor leaf segment veins, the inflorescences not pendant below the leaves, the abaxially lepidote sheathing inflorescence bracts, the lower density of flowers on the rachilla, the tubular to cupulate calyx, the larger fruits and the larger seeds. 

 Distribution:— This species occurs on the islands of Bonaire and Curaçao. On Bonaire, the plants are found in the southern part of the island, west of Lac Bay and north of the solar salt factory. On Curaçao, the plants are within and to the west of Christoffelpark, on the western side of Christoffelberg.

 Habitat:— On Bonaire, the plants are found in the Coccoloba–Melocactus Middle Terrace landscape type (de Freitas et al. 2005), on limestone pavements, at elevations near 5 m. On Curaçao, the plants are found in the Bromelia– Schomburgkia Hills landscape type (Beers et al. 1997), on cherty mudstones, at elevations between 140–260 m.

Local Names:— The plant is called Cabana or Sabalpalm in the Dutch Caribbean. 
Etymology:— The name honors the Dutch Antilles, where the species is endemic.

[Herpetology • 2017] Species Delimitation of the Blue-spotted Spiny Lizard within A Multilocus, Multispecies Coalescent Framework, Results in the Recognition of A New Sceloporus Species; Sceloporus gadsdeni

 DOI: 10.1016/j.ympev.2017.04.004 

• Reciprocal monophyly supported clades were found for Sceloporus cyanostictus.
• Parametric coalescent-based method confirms two different lineages.
• A new species of Sceloporus is recognized and described.

Species delimitation is a major topic in systematics. Species delimitation methods based on molecular data have become more common since this approach provides insights about species identification via levels of gene flow, the degree of hybridization and phylogenetic relationships. Also, combining multilocus mitochondrial and nuclear DNA leads to more reliable conclusions about species limits. Coalescent-based species delimitation methods explicitly reveal separately evolving lineages using probabilistic approaches and testing the delimitation hypotheses for several species. Within a multispecies, multilocus, coalescent framework, we were able to clarify taxonomic uncertainties within S. cyanostictus, an endangered lizard that inhabits a narrow strip of the Chihuahuan Desert in Mexico. We included, for the first time in a phylogenetic analysis, lizards from the three populations of S. cyanostictus recognized so far (East Coahuila, West Coahuila and Nuevo León). Phylogenetic analysis corroborates the hypothesis of two separately evolving lineages, i.e. the East and West Coahuila populations, as proposed in a previous study. We also found a distant phylogenetic relationship between the lizards from Nuevo León and those of East and West Coahuila. Finally, based on the species delimitation results, we propose and describe a new species of SceloporusSceloporus gadsdeni sp. nov.

The ventral pattern has a blue patch that joins in the middle of the belly and the chest with black borders in males; in contrast, in Scyanostictus the chest and undersurfaces of arms are pale grayish blue with melanin specks, each flank has a poorly defined bluish black belly patch sometimes without contact in the middle of the belly. According to currently available published information, S. cyanostictus from eastern Coahuila has 6 superciliars and 6 infralabials (Axtell and Axtell, 1971), while S. gadsdeni has 4 superciliar scales on each side of the head and 5 infralabials with uncertainty on this character due to sample size (Table 2).

The distribution of S. gadsdeni is restricted to the Sierras Texas, Solis and San Lorenzo mountain ranges in southwestern Coahuila, and this species inhabits rock walls, boulders and canyons. These mountains are separated from the location of S. cyanostictus by ca. 190 km as the crow flies and immersed within the low Mayran Basin.

Etymology: This species is named in honor of Hector Gadsden, a researcher who has made praiseworthy contributions to the ecology and conservation of the herpetofauna of La Comarca Lagunera and the Chihuahuan Desert. The suggested common name alludes to its restricted distribution within the La Comarca Lagunera region.
