The species known in America as the European spruce sawfly has been shown to be one of two species which have been confused under the name Gilpinia polytoma (Hartig) (1). One is arrhenotokous and is known only from Europe, and the other is thelytokous and occurs in Europe and America. This paper seeks to establish the correct nomenclature and provide adequate descriptions of the two species.

We re-examined the taxonomic status of plants treated as Sedum formosanum (Crassulaceae) from Miyako-jima Island of the Ryukyu Islands, Japan, using morphological comparison and molecular phylogenetic analyses with related species. In morphology, plants from Miyako-jima Island bore a close resemblance to the other plants of S. formosanum, but differed in being perennial, polycarpic, and having lateral axillary branches. Molecular analyses based on ITS of nrDNA and six regions of cpDNA sequencing indicated that the Miyako-jima plants formed a distinct subclade. This subclade was part of a polytomy with three other subclades comprising nine taxa endemic to Taiwan and S. formosanum from other areas, including the type locality. Therefore, we propose and describe the Miyako-jima plants as a new subspecies, Sedum formosanum subsp. miyakojimense.

A new species of scincid lizard allied to Plestiodon japonicus (Peters, 1864) was described as P. finitimus sp. nov., fromthe eastern part of Honshu and Hokkaido, Japan. A previous DNA study reported the taxonomic status of the easternJapanese populations of Plestiodon as an undescribed species on the basis of their collective genetic distinctness from aparapatric congener P. japonicus sensu strict from the western part of mainland Japan. We present the diagnostic featuresof P. finitimus compared to P. japonicus and P. latiscutatus Hallowell, 1861, the other parapatric species occurring in theIzu Peninsula and Izu Islands of central Japan, on the basis of morphological characteristics and DNA barcode patterns.Both P. finitimus and P. japonicus have a small postnasal and large anterior loreal that contacts the supralabials. In contrast,the Izu Peninsular populations of P. latiscutatus, which had no known diagnostic features relative to the other two species,usually have a large postnasal and small anterior loreal, with the latter separated from the supralabials by the former, ormay otherwise lack a postnasal. In most populations of P. finitimus, the right and left prefrontals are usually isolated fromeach other, whereas they exhibit medial contact in most populations of P. japonicus. Although all the above characters arevariable both within and between populations, 60–90% of the specimens from each locality on mainland Japan werecorrectly identified using a combination of these characters. Based on these characters, the Russian Far East populationof Plestiodon was also identified as P. finitimus. The interspecific sequence differences in the standard DNA barcoderegion (a 658 base pair fragment of the cytochrome c oxidase subunit I gene of mitochondrial DNA) were distinct, andeach of the three species was exclusively clustered in a neighbor-joining tree. The limited hybridization among the threespecies indicated by previous studies suggests that DNA barcodes could provide a reliable key for their correctidentification. The implications for the biogeography and speciation of the three parapatric lizard species are briefly discussed.

The phylogenetic relationships of Sciurus species present in Mesoamerica are addressed using a morphological analysis under Maximum Parsimony. Our results recovered the existence of two clades: one comprising S. aureogaster, S. colliaei, S. variegatoides and Syntheosciurus brochus and the other clade composed by S. richmondi, S. granatensis, S. deppei, S. yucatanensis and Microsciurus alfari. The taxonomic status of the genera Microsciurus and Syntheosciurus is discussed as well the biogeographic implications of these findings.

The region of Lagoa Santa, Minas Gerais, Brazil, is one of the most important karstic areas of the Brazilian Quaternary due to the faunistic diversity of living and extinct forms. Among them, some taxa remain poorly studied, as is the case of Calomys anoblepas Winge 1887. Despite the recent allocation of the taxon within Juliomys, its description and morphological analysis are condensed, based on comparative few specimens and on few informative characters. In this study, we investigate characters proposed to distinguish species of Juliomys, and reevaluate the taxonomic status of the fossil Juliomys anoblepas. We analyzed 80 cranio-dental morphological characters in 233 specimens represented by the four species currently recognized: J. pictipes (Osgood 1933), J. rimofrons Oliveira & Bonvicino 2002, J. ossitenuis Costa, Pavan, Leite & Fagundes 2007, and J. ximenezi Christoff, Vieira, Oliveira, Gonçalves, Valiati & Tomasi 2016. We also performed principal component analysis on eight craniodental measurements available for the J. anoblepas hypodigm. The review of morphological systems and the evaluation of the characters used in the literature revealed that there are no diagnostic characters in the anterior portion of the skull and in the molar series of Juliomys, being difficult to differentiate the fossil from the other living species. Only six qualitative characters were variable and applicable to the hypodigm of J. anoblepas. Characters are polymorphic, invariable, or the fossil is not sufficiently complete to determinate its states. The taxon could not be morphometrically differentiated from J. pictipes and J. ossitenuis. Based on the results presented herein, we consider J. anoblepas as a nomen dubium and restrict its name to the taxon’s hypodigm.

Genetic Diversity And Structure

Abstract The binturong or bearcat is a forest mesocarnivore ranging from Nepal to Indonesia and the Philippines. Several subspecies of binturongs are recognized but a revision is needed. The binturong from Palawan was described as a species and is now considered a subspecies, but its status has never been checked using molecular approaches. Owing to its restricted range and the pressure on its habitat, the Palawan binturong may be endangered. It is, therefore, of crucial importance to clarify its taxonomic status, particularly for the management of captive populations. We sequenced one nuclear and two mitochondrial markers for binturongs from locations across the species range and from zoos. Our results provide an assessment of the genetic polymorphism and structure within the binturong, resulting in two groups, corresponding to the Indochinese and the Sundaic regions. Within the latter were found the Palawan binturongs on one side, and an individual from Sulu archipelago (a locality not reported before) on the other side. The Palawan binturongs form a monophyletic group, genetically close to Bornean binturongs, which suggests that they may have dispersed from Borneo, and represents a lineage worth preserving, but which is not a separate species nor a separate subspecies.

Alocasia fallax Schott and A. odora (Roxb.) Koch (Araceae) were investigated cytogenetically to confirm their taxonomic status. There is no report of 2n chromosome number for A. fallax in the available literature and internet information. Therefore the 2n chromosome number (2n = 28) found in this study is probably the first report for A. fallax. Alocasia odora showed exactly double 2n chromosome number (2n = 56) from A. fallax. In addition to chromosome number, the other karyotypic features of A. odora were exactly double for that of A. fallax. The centromeric formulae of A. fallax was 24 m + 4 sm whereas it is just double in A. odora. Total length of 2n chromosome complement of A. odora (62.58 μm) was almost double to A. fallax. The range of chromosomal length of the two species was almost same. Moreover, A. odora plant is much taller than A. fallax. All of these data suggests that A. odora might be an autotetraploid of A. fallax which in course of evolution had undergone some changes in GC-rich repeats.

A new species of raninid crustacean, Vegaranina rivasi sp. nov, is described based on three specimens collected from a Late Cretaceous deposit in central Cuba. Previous studies assigned one of the specimens to Vegaranina precocia (Feldmann, Vega, Tucker, Garcia-Barrera & Avendano, 1996), a species described from the Late Cretaceous of Mexico. However, after collecting the new specimens and recent major revisions of the group, we identified a unique combination of characters in the Cuban specimens that separate them from the other species in the genus.

Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

We report a new species of Spermophilus ( Rodentia: Sciuridae), here designated as S. torosensis sp. nov., distributed in the Taurus Mountains in southern Anatolia, Turkey. A total of 161 specimens of the genus Spermophilus from Turkey and Iran were analyzed for their morphological, morphometric, and karyological characteristics. Uni- and multi-variate statistical analyses of morphologic data for 95 adult specimens yielded 4 distinct groups. Taxonomic evaluations classified the specimens into 4 species Spermophilus citellus, S. xanthopymnus, S. fulvus and S. torosensis sp. nov. Morphometrics, coat coloration, a brush-shaped tail, and a NFa value of 72 are diagnostic characters that distinguish S. torosensis sp. nov. from the other species. In Turkey, S. torosensis sp. nov. was found in 6 locations. The karyotype of S. fulvus also is described for the first time as 2n= 36, NFa= 70 and NFa= 66; new karyotypic data is reported for S. xanthoprymnus from Iran and Turkey.

A New Species

The first record of the straptail fish, genus Macruronus, from South Africa was based on a single specimen captured off the Atlantic Cape coast and described as a new species, M. capensis Davies 1950. Davies did not examine specimens of the other extant nominal species in the genus, but based his conclusions solely on references to the original descriptions of M. novaezelandiae (Hector 1870) and M. magellanicus Lönnberg 1907. We show that all of the characters used by Davies (1950) to distinguish M. capensis from its congeners are in fact shared by the other nominal species of this genus. We also present molecular evidence from a Macruronus specimen recently caught off South Africa to support the conclusion that M. capensis is a junior synonym of M. novaezelandiae.
