[PaleoMammalogy • 2017] Anatoliadelphys maasae • Skeleton of An Unusual, Cat-sized Marsupial Relative (Metatheria: Marsupialiformes) from the middle Eocene (Lutetian) of Turkey

Anatoliadelphys maasae  Maga & Beck, 2017


We describe a near-complete, three-dimensionally preserved skeleton of a metatherian (relative of modern marsupials) from the middle Eocene (Lutetian: 44–43 million years ago) Lülük member of the Uzunçarşıdere Formation, central Turkey. With an estimated body mass of 3–4 kg, about the size of a domestic cat (Felis catus) or spotted quoll (Dasyurus maculatus), it is an order of magnitude larger than the largest fossil metatherians previously known from the Cenozoic of the northern hemisphere. This new taxon is characterised by large, broad third premolars that probably represent adaptations for hard object feeding (durophagy), and its craniodental morphology suggests the capacity to generate high bite forces. Qualitative and quantitative functional analyses of its postcranial skeleton indicate that it was probably scansorial and relatively agile, perhaps broadly similar in locomotor mode to the spotted quoll, but with a greater capacity for climbing and grasping. Bayesian phylogenetic analysis of a total evidence dataset comprising 259 morphological characters and 9kb of DNA sequence data from five nuclear protein-coding genes, using both undated and “tip-and-node dating” approaches, place the new taxon outside the marsupial crown-clade, but within the clade Marsupialiformes. It demonstrates that at least one metatherian lineage evolved to occupy the small-medium, meso- or hypo-carnivore niche in the northern hemisphere during the early Cenozoic, at a time when there were numerous eutherians (placentals and their fossil relatives) filling similar niches. However, the known mammal fauna from Uzunçarşıdere Formation appears highly endemic, and geological evidence suggests that this region of Turkey was an island for at least part of the early Cenozoic, and so the new taxon may have evolved in isolation from potential eutherian competitors. Nevertheless, the new taxon reveals previously unsuspected ecomorphological disparity among northern hemisphere metatherians during the first half of the Cenozoic.

Anatoliadelphys gen. nov.  
Anatoliadelphys maasae sp. nov.  

Etymology: Anatolia (Greek): the geographic name for the Asian part of Turkey; delphys (Greek): uterus, a common suffix for marsupials and their fossil relatives; maasae: in honour of Dr. Mary Maas and her contributions to Paleogene mammalian palaeontology, particularly in Turkey.

Holotype: Ankara Üniversitesi Jeoloji Müzesi (AÜJM) specimen 2002–25, which comprises a fragmented partial cranium, both dentaries, and associated postcranial elements, including most of the vertebral column, partial pectoral and pelvic girdles, all of the long limb bones, both calcanei, two metapodials, and a few phalanges.

Locality and age: AÜJM 2002–25 was collected from the Lülük member of the Uzunçarşıdere Formation (UCF), which is part of the small Orhaniye-Güvenç sedimentary basin located at the northwestern edge of the city of Ankara, approximately 5 km southwest of the town of Kazan, in central Turkey. The Lülük member is the lowest of the three members currently recognised within the UCF (together with the Gökdere [middle], and Sarıbeyler [upper] members), and is the source of all fossil mammals known from the UCF to date. AÜJM 2002–25 is from locality AK33, which is approximately 90m above the base of the UCF, at Memlik village. Until recently, the age of the UCF was poorly constrained, but a combination of U-Pb dating of zircons and magnetostratigraphy now support a date of 44–42 MYA (= Lutetian) for the formation as a whole, and 44–43 MYA for the Lülük member.

Diagnosis: Anatoliadelphys maasae differs from all other metatherians in the following combination of features: comparatively large size (estimated body mass 3–4 kg); premolars increase markedly in size posteriorly (occlusal area of p1 less than one sixth that of p3); P3 and p3 very large (similar in occlusal area to M2 and m2 respectively) and also broad (labiolingual width:mesiodistal length ratio is 0.89 for P3 and 0.7 for p3); modified tribosphenic molar dentition, in which M1-3 and m1-4 increase markedly in size posteriorly (occlusal area of M1 approximately one third that of M3; occlusal area of m1 approximately one seventh that of m4); upper molars with cingula extending along the anterior and posterior margins; protocone large but conules indistinct or absent; metacone taller than the paracone on M3 but smaller than the paracone on M4; centrocrista v-shaped on M3, with the premetacrista extending labially to stylar cusp D; centrocrista straight on M4; parastylar lobe very large on M4; anterior cingulid weakly developed on m3-4; m4 trigonid dominated by enormous protoconid, with paraconid and metaconid both greatly reduced; preentocristid and cristid obliqua of m3-4 both with carnassial notch; posterior cingulid present but very faint on m3-4; strongly curved radius and tibia; femur with prominent third trochanter, well-marked trochlea and distal condyles of approximately equal width; calcaneus with medially-inflected tuber, large peroneal process with prominent groove for peroneus longus tendon, concave calcaneocuboid facet, and prominent pit (probably for plantar calcaneocuboid ligament) on ventral surface.

[Botany • 2017] Argostemma cordatum • A New Species (Rubiaceae) from southern Vietnam

Argostemma cordatum Nuraliev


Argostemma cordatum, a new species of Rubiaceae, is described and illustrated. The species was discovered in 2014 during a botanical survey of the Chu Yang Sin National Park (Dak Lak province, Southern Vietnam). Argostemma cordatum possesses a solitary large leaf per plant (along with one very small leaf). The new species differs from morphologically similar species mainly by the small size of the enlarged leaf and cordate base of the enlarged leaf. It is also characterized by the following features: plant completely glabrous, stipules minute and reduced to papillate warts, inflorescence with all axes elongated, anthers coherent into anther cone and dehiscent by longitudinal slits, style slightly exserted. An extended description of the vegetation in the area inhabited by A. cordatum is provided.

[Ichthyology • 2017] Taxonomic Revision of the Seasonal Killifish Genus Nothobranchius (Cyprinodontoidei: Aplocheilidae) from Zanzibar, East Africa

Nothobranchius guentheri and Nothobranchius melanospilus, the two seasonal killifishes of the genus Nothobranchius occurring in Zanzibar Island, Tanzania, were involved in past taxonomical mistakes and are still misidentified in museum collections. A historical review is herein presented and both species are redescribed on the basis of type material and recent collections. Nothobranchius guentheri, a popular aquarium fish, is endemic to Zanzibar, and N. melanospilus, geographically widespread in East Africa, occurring both in Zanzibar and in continental river basins. These species are distinguished by a series of morphological features not previously reported in the literature, including pre-dorsal length and relative position of the anterior portion of the dorsal-fin skeletal support and vertebrae; number of gill-rakers of the first branchial arch, caudal-fin rays, scales of the longitudinal series, series of scales around caudal peduncle, and vertebrae; frontal squamation; and arrangement and number of neuromasts of the supraorbital series. The present taxonomic revision comprising N. guentheri and N. melanospilus, the oldest species names of the genus in the East African biodiversity hotspot, is important to improve the knowledge of the genus in a region where its taxonomy is still problematic

Giant sengis (Macroscelidea; Macroscelididae; Rhynchocyon), also known as giant elephant-shrews, are small-bodied mammals that range from central through eastern Africa. Previous research on giant sengi systematics has relied primarily on pelage color and geographic distribution. Because some species have complex phenotypic variation and large geographic ranges, we used molecular markers to evaluate the phylogeny and taxonomy of the genus, which currently includes four species: R. chrysopygus, R. cirnei (six subspecies), R. petersi (two subspecies), and R. udzungwensis. We extracted DNA from fresh and historical museum samples from all taxa except one R. cirnei subspecies, and we generated and analyzed approximately 4700 aligned nucleotides (2685 bases of mitochondrial DNA and 2019 bases of nuclear DNA) to reconstruct a molecular phylogeny. We genetically evaluate Rhynchocyon spp. sequences previously published on GenBank, propose that the captive R. petersi population in North American zoos is likely R. p. adersi, and suggest that hybridization among taxa is not widespread in Rhynchocyon. The DNA sample we have from the distinctive but undescribed giant sengi from the Boni forest of northern coastal Kenya is unexpectedly nearly identical to R. chrysopygus, which will require further study. Our analyses support the current morphology-based taxonomy, with each recognized species forming a monophyletic clade, but we propose elevating Rhynchocyon cirnei stuhlmanni to a full species [Rhynchocyon stuhlmanni].

Anisogomphus yingsaki sp. nov. (holotype male: Ban Na Kha, Ban Muang, Sakon Nakhon province, Thailand, altitude 170–175 m, 22-vi-2016) is described and illustrated. The new species is most similar to A. bivittatus from India and Nepal, and also A. flavifacies, and A. resortus from China in the shape of anal appendages. However, it can be separated from all of these by a combination of the following characters: shape of antehumeral stripes, abdominal pattern, shape of vesica spermalis and female valvula vulvae. The behavior of the new species, including crepuscular activity, is briefly discussed.

[Gastropoda • 2017] Attenborougharion gen. nov. (Mollusca: Pulmonata: Helicarionidae): A Likely Case of Convergent Evolution in southeastern Tasmania

Attenborougharion rubicundus (Dartnall & Kershaw, 1978)

Hyman & Köhler, 2017  

Helicarion Férussac, 1821 from southeastern Australia currently comprises five species of endemic semislugs. Analyses of comparative morphological data and partial sequences of the mitochondrial genes cytochrome c oxidase subunit I (COI) and 16S rRNA (16S) reveal that one of these species, Helicarion rubicundus Dartnall & Kershaw, 1978, which is restricted to southeastern Tasmania, is not closely related to the other known species of this genus. This species is distinguished from Helicarion in several key morphological characters, such as the bright two-toned red and green colouration of its larger body with a flattened tail that is keeled only at the tip, the triangular shape of the pneumostome, the degree and type of folding present in the spermoviduct and free oviduct, the presence of a longer, more slender bursa copulatrix, the presence of a small epiphallic caecum and a hooked flagellum, and the presence of irregular longitudinal pilasters in the penial interior in contrast to the v-shaped rows of papillose lamellae seen in Helicarion. Moreover, the mitochondrial phylogeny provides evidence that this species is phylogenetically distinct from Helicarion as well as any other currently described genus from southeastern Australia. Based on these findings, we here describe a new genusAttenborougharion, for this species.

Helicarion rubicundus Dartnall & Kershaw, 1978: 2; Kershaw, 1980: 213.

Distribution and conservation status: Attenborougharion rubicundus is found only on the Tasman and Forestier Peninsulas in Tasmania (Taylor, 1991; Otley et al., 1999). The total known extent of occurrence of this species is 85, leading to its listing as Vulnerable on the IUCN Red List of Threatened Species. In addition to its restricted range, within this area Attenborougharion rubicundus inhabits only closed wet forests and is not found in dry forests or damp sclerophyll forests (Otley eal., 1999), making it vulnerable to habitat loss through the effects of climate change as well as habitat destruction through changed land use.

[PaleoEntomology • 2017] Mesosticta davidattenboroughi • Mesostictinae subfam. nov., An Archaic Group of Platystictid Damselflies (Odonata: Zygoptera) from mid-Cretaceous Burmese Amber

Mesosticta davidattenboroughi
 Zheng, Wang, Nel, Jarzembowski, Zhang & Chang, 2017


Odonatans are quite rare in the fossil record compared with the other insects, especially in Cretaceous amber inclusions. The extant family Platystictidae is one of the most diverse Zygoptera, but short of fossil records. In this paper, a new species, Mesosticta davidattenboroughi sp. nov., is described from mid-Cretaceous Burmese amber, representing the third-known fossil species of Platystictidae. Mesosticta davidattenboroughi sp. nov. has a long IR1 beginning one cell distal of the base of RP2, confirming the previous attribution of Mesosticta Huang, Azar, Cai & Nel, 2015 to Platystictidae. It differs from other species of Mesosticta in having a long IR1 and a basally crossed subdiscoidal cell. The fossil genus Mesosticta shares the diagnostic characters of the modern platystictid genera, viz. a basally recessed ‘CuP’ (shared by all species), a very long IR1 (only in Mesosticta davidattenboroughi sp. nov.), and a specialized subdiscoidal area mostly rhomboidal in shape (only in Mesosticta electronica Zheng, Zhang, Chang & Wang, 2016). Based on the platystictid damselflies from Burmese amber, a new subfamily Mesostictinae subfam. nov. is established. Mesostictinae subfam. nov. represents the first fossil group of modern platystictid damselflies, documenting the appearance of Platystictidae as early as mid-Cretaceous. It differs from modern Platystictidae by the presence of fewer postnodal and postsubnodal crossveins, a short MP, the base of RP2 being nearer to the subnodus and the nodus lying more distally.

[Herpetology • 2017] On The Taxonomic Status of Eurylepis poonaensis (Squamata: Scincidae): Resolving A Long-standing Conundrum

Eurylepis poonaensis (Sharma, 1970) 



 The scincid genus Eurylepis was split off from the cosmopolitan genus Eumeces sensu lato, with Eurylepis taeniolatus being the type species, which is taxonomically poorly understood. The other nominate species in this genus is Eurylepis poonaensis, which was known only from its type locality and original description, and is the only known member of the subfamily Scincinae from near the Western Ghats. However, earlier studies raised doubts about its specific validity, often without examining type or other specimens. We collected fresh samples of this species from the type locality and nearby areas. Based on the examination of the holotype and the new material, we provide a detailed redescription of E. poonaensis, additional data on its skeletal structure, habitat, and natural history. We also provide a detailed redescription of E. taeniolatus based on the holotype to avoid further taxonomic ambiguity.

[Ichthyology • 2017] Parapercis binotata • A New Species of Parapercis (Teleostei: Pinguipedidae) from the Solomon Islands

Parapercis binotata Allen & Erdmann, 2017


A new species of pinguipedid fish, Parapercis binotata, is described from the Solomon Islands on the basis of six adult specimens, 46.5–56.5.5 mm SL. The new taxon belongs to the Parapercis cylindrica complex, which contains five other western Pacific Ocean species: P. australis, P. cylindrica, P. haackei, P. lineopunctata, and P. snyderi. It is most similar to P. lineopunctata from the East Indian Archipelago, but adult males are clearly distinguished by the presence of two short black bands, one on the cheek and another on the lower pectoral fin. Although lacking these markings, females differ from those of P. lineopunctata by the presence of a curved black band below the eye. The only known habitat of the new species consists of a nearly enclosed lagoon in 4-8 m depth. Analyses of the mtDNA “barcode” marker COI sequences for the P. cylindrica species complex show exceptionally deep divergences between most species, about 15–20% divergence between all but one pair of species, with P. binotata 14.52% different from its nearest relative, P. lineopunctata.

Diagnosis. Dorsal-fin rays V,21; anal-fin rays I,16–17; pectoral-fin rays 14–16; lateral-line scales 46–48; four, progressively larger, recurved canine teeth on each side at front of lower jaw; scales on body ctenoid except cycloid on prepelvic area; opercle and cheek covered with ctenoid scales; body depth 4.7–5.5 in SL; caudal fin truncate to slightly rounded; pelvic fins reaching beyond anal-fin origin; color of head and body generally white, 7–8 short brown bars on back, above lateral line and lower side with corresponding narrow yellow-orange to brown bars; adult with conspicuous black band on rear edge of cheek and short black band on lower pectoral-fin rays; females with curved black band under eye along lower edge of suborbital; found on sand substrates in depths of less than 10 m.

Etymology. The species is named binotata (Latin: two markings), with reference to the diagnostic dark bands on the cheek and pectoral fins of males. It is treated as a feminine singular compound adjective.

Distribution and habitat. The new species is known only from the Solomon Islands type locality. The relatively unusual habitat consisted of a nearly enclosed, narrow, dead-end lagoon (Fig. 3) with a gradually sloping, white sand bottom with scattered, mainly low-profile, coral formations. The fish was common at depths between about 4–8 m, generally occurring as solitary individuals
