[Paleontology • 2017] Luskhan itilensis • Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs

Luskhan itilensis 
Fischer, Benson, Zverkov, Soul, Arkhangelsky, Lambert, Stenshin, Uspensky & Druckenmiller, 2017

  Reconstruction by Andrey Atuchin.

• A new unusual pliosaur marine reptile is described from the Cretaceous of Russia
• Ecomorphological convergence is assessed in short-necked plesiosaurs
• Pliosaurs repeatedly evolved longirostrine piscivorous forms
• Profound convergence characterizes the evolution of short-necked plesiosaurs

Plesiosaurs were the longest-surviving group of secondarily marine tetrapods, comparable in diversity to today’s cetaceans. During their long evolutionary history, which spanned the Jurassic and the Cretaceous (201 to 66 Ma), plesiosaurs repeatedly evolved long- and short-necked body plans. Despite this postcranial plasticity, short-necked plesiosaur clades have traditionally been regarded as being highly constrained to persistent and clearly distinct ecological niches: advanced members of Pliosauridae (ranging from the Middle Jurassic to the early Late Cretaceous) have been characterized as apex predators, whereas members of the distantly related clade Polycotylidae (middle to Late Cretaceous) were thought to have been fast-swimming piscivores. We report a new, highly unusual pliosaurid from the Early Cretaceous of Russia that shows close convergence with the cranial structure of polycotylids: Luskhan itilensis gen. et sp. nov. Using novel cladistic and ecomorphological data, we show that pliosaurids iteratively evolved polycotylid-like cranial morphologies from the Early Jurassic until the Early Cretaceous. This underscores the ecological diversity of derived pliosaurids and reveals a more complex evolutionary history than their iconic representation as gigantic apex predators of Mesozoic marine ecosystems suggests. Collectively, these data demonstrate an even higher degree of morphological plasticity and convergence in the evolution of plesiosaurs than previously thought and suggest the existence of an optimal ecomorphology for short-necked piscivorous plesiosaurs through time and across phylogeny.

[Ornithology • 2017] The Role of Niche Divergence and Geographic Arrangement in the Speciation of Eared Pheasants (Crossoptilon, Hodgson 1938)

 Wang, Liu, Liu, Chang, Wang & Zhang, 2017  DOI: 10.1016/j.ympev.2017.05.003 

• The phylogenetic relationship of Eared Pheasants was resolved based on 45 loci.
• Asymmetric historical gene flow occurred between both parapatric and allopatric sister species.
• Allopatric sister species exhibit significantly divergent ecological niches whereas parapatric sister species show niche conservatism.
• Ecological divergence may have been the main factor that promoted ecological niche divergence.

One of the most contentious theories in current ecology is the ecological niche conservatism, which is defined as conservatism among closely related species; however, the ecological niche can also be shifted, as documented in several cases. Genetic drift and ecological divergent selection may cause ecological niche divergence. The current study aims to test whether the ecological niche is conserved or divergent and to determine the main factor that drives ecological niche divergence or conservation. We analyzed the phylogenetic relationship, ecological niche model (ENM) and demographic history of Eared Pheasants in the genus Crossoptilon (Galliformes: Phasianidae) to test niche conservatism with respect to different geographically distributed patterns. The phylogenetic relationship was reconstructed using ∗BEAST with mitochondrial cytochrome b (cyt b) and 44 unlinked autosomal exonic loci, and ENMs were reconstructed in MAXENT using an average of 41 occurrence sites in each species and 22 bioclimatic variables. A background similarity test was used to detect whether the ecological niche is conserved. Demographic history was estimated using the isolation with migration (IM) model. We found that there was asymmetric gene flow between the allopatric sister species Crossoptilon mantchuricum and C. auritum and the parapatric sister species C. harmani and Ccrossoptilon. We found that ecological niches were divergent, not conserved, between Cmantchuricum and Cauritum, which began to diverge at approximately 0.3 million years ago. However, the ecological niches were conserved between C. crossoptilon and C. harmani, which gradually diverged approximately half a million years ago. Ecological niches can be either conserved or divergent, and ecological divergent selection for local adaptation is probably an important factor that promotes and maintains niche divergence in the face of gene flow. This study provides a better understanding of the role that divergent selection has in the initial speciation process. The platform combined demographic processes and ecological niches to offer new insights into the mechanism of biogeography patterns.

[Ichthyology • 2017] Compsaraia iara • A New Species of Deep-Channel Electric Knifefish Compsaraia (Apteronotidae, Gymnotiformes) from the Amazon River

Compsaraia iara
Bernt & Albert, 2017
  DOI: 10.1643/CI-16-529 
The deep channels of large rivers throughout the humid Neotropics are occupied by diverse and abundant assemblages of electric knifefishes. Historically this habitat has been poorly sampled, but extensive benthic trawling efforts in the Brazilian Amazon in the 1990s produced large numbers of electric fishes especially in the family Apteronotidae. A large number of these specimens, initially identified as Porotergus, have been found to belong within Compsaraia, a genus with two species described from the Orinoco and western Amazon. From this material we describe a new species, from the Amazon River in Brazil, and provide a new diagnosis for the genus. This species is readily distinguished from congeners by a short, rounded snout and small, subterminal mouth with reduced dentition. This species inhabits large rivers in the Eastern and Central Amazon between Ilha Grande de Gurupá and the mouth of the Rio Içá. This description brings the total number of valid apteronotid species to 95.

[Invertebrate • 2017] Overview of the Ferdina-like Goniasteridae (Echinodermata: Asteroidea) Including A New Subfamily, Ferdininae, Three New Genera and Fourteen New Species

Ferdina mena  Mah, 2017


Recent assignment of some goniasterid-like Ophidiasteridae into the Goniasteridae has led to further re-evaluation of other ophidiasterids as possible goniasterids. This led to the discovery of new genera and species supported by a distinctive set of characteristics which support a new subfamily, the Ferdininae, a group originally outlined by Marsh and Price (1991) within the Goniasteridae. The historical Ophidiasteridae is paraphyletic and includes several nominal ophidiasterid genera (e.g., Fromia, Neoferdina, etc.). Newly described material has led to the inclusion of six genera,within this group, of which three, Bathyferdina n. gen.Eosaster n. gen., and Kanakaster n. gen.are newly describedFourteen new species in five genera are described. This includes Bathyferdina aireyae n. gen., n. sp.Eosaster nadiae n. gen., n. sp.Ferdina mena n. sp.Kanakaster balutensis n. gen., n. sp.Kanakaster convexus n. gen., n. sp.Kanakaster discus n. gen., n. sp.Kanakaster larae n. gen., n. sp.Kanakaster plinthinos n. gen., n. sp.Kanakaster solidus n. gen., n. sp.Neoferdina annae n. sp.Neoferdina antigorum, n. sp.Neoferdina momo, n. sp.Neoferdina oni, n. sp., and Paraferdina plakos, n. sp. Identification keys, synopses, and description of these taxa are included.

[Ichthyology • 2017] Pempheris familia • A New Species of Pempheris (Perciformes: Pempheridae) endemic to the Ogasawara Islands, Japan

Pempheris familia  Koeda & Motomura, 2017

    DOI:  10.1007/s10228-017-0586-3 

Pempheris familia sp. nov. is described on the basis of two specimens collected from the Ogasawara Islands, Japan. The new species is most similar to Pempheris japonica Döderlein in Steindachner and Döderlein 1883, endemic to Japanese and Korean waters, in having adherent scales with strong ctenii on the lateral and ventral surfaces of the body, each scale expanded basally and distally due to central narrowing, the abdomen with a U-shaped cross-sectional outline, a large ventral fenestra between the coracoid and cleithrum, 10 dorsal-fin soft rays and 35 or 36 anal-fin soft rays. However, Pempheris familia can be distinguished from P. japonica by the following combination of characters: 84–88 pored lateral-line scales; 14 or 15 scale rows above the lateral line; 50–55 predorsal scales; 26 circumpeduncular scales; and a distinct blackish blotch on the pectoral-fin base. Pempheris familia appears to be endemic to the Ogasawara Islands.

Pempheris familia sp. nov.
(Standard Japanese name: Bonin-hatampo) 

Diagnosis. A species of Pempheris with the following combination of characters: lateral and ventral body scales strongly ctenoid, adherent, with distinct basal and distal portions; abdomen cross-sectional outline U-shaped; large ventral fenestra between coracoid and cleithrum; 10 dorsal-fin soft rays; 35–36 anal-fin soft rays; 84–88 pored lateral-line scales; 14–15 scale rows above lateral line; 50–55 predorsal scales; 26 circumpeduncular scales; body orange-copper; blackish blotch on fins limited to tip of dorsal, anal and caudal fins; distinct blackish blotch on pectoral-fin base.

Etymology. The specific name of the new species, familia, means “family” in Greek. The Ogasawara Islands include ca. 30 islands, many of them having been given family-like names; for example, Chichi-jima = father island, Haha-jima = mother island, Ane-jima = older sister island. Ototo-jima, where the type specimens were collected, and Ani-jima, where the underwater photographs were taken, refer to younger and older brothers, respectively.

[Cnidaria • 2017] Sinularia mesophotica • Search for Mesophotic Octocorals (Cnidaria, Anthozoa) and Their Phylogeny. II. A New Zooxanthellate Species from Eilat, northern Red Sea

Sinularia mesophotica 
Benayahu, McFadden, Shoham & van Ofwegen, 2017   

An octocoral survey conducted in the mesophotic coral ecosystem (MCE) of Eilat (Gulf of Aqaba, northern Red Sea) yielded a new species of the speciose reef-dwelling genus Sinularia. It features encrusting colony morphology with a thin, funnel-shaped polypary. Sinularia mesophotica sp. n. (family Alcyoniidae) is described and compared to the other congeners with similar morphology. Both the morphological and molecular examination justified the establishment of the new species, also assigning it to a new genetic clade within Sinularia. The results highlight its unique phylogenetic position within the genus, and this is the first described species of a mesophotic zooxanthellate octocoral.

Figure 1. Sinularia mesophotica sp. n.; A Holotype ZMTAU Co 37425 B paratypes ZMTAU Co 37492.
Scale bar: 1 cm (A also applies to B). 

Diagnosis: The holotype is part of an encrusting colony with a thin, funnel-shaped polypary, also featuring a curly margin (Fig. 1A). In a side-view its maximum dimensions are 5 × 2.5 cm. Polyps with tentacle rods and collaret sclerites (Fig. 2A–C). Tentacle rods up to 0.10 mm long (Fig. 2A). Collaret consists of almost straight spindles, up to 0.20 mm long (Fig. 2B), and shorter bent ones, up to 0.14 mm long (Fig. 2C). Surface layer of the polypary with clubs (Fig. 2D), some featuring a central wart, while in others it is less discernible, or even absent. Clubs vary from 0.10 mm long to 0.25 mm long, and a few with poorly developed heads attain 0.27 mm (Fig. 2E). Surface layer of the colony base contains clubs up to 0.22 mm; some similar to those of polypary, and others have wide heads (Fig. 3A). Polypary and base interior bear spindles, some branched, up to 3.2 mm long (Fig. 3B), with well-spaced simple tubercles (Fig. 3C).

Etymology: The new species name reflects its mesophotic habitat.

[Botany • 2017] Hibiscus contortus | ชบาหุบ • A New Species of Hibiscus (Malvaceae-Malvoideae) from Thailand

ชบาหุบ |  Hibiscus contortus  Phuph. & S.Gardner


A new speciesHibiscus contortus Phuph. & S.Gardner, is described and contrasted to its nearest ally, H. floccosus Mast.

KEYWORDS: Malvaceae-Malvoideae; Hibiscus; new species; conservation; Thailand

Hibiscus L. comprises approximately 200 species distributed almost worldwide, mostly in the tropics and subtropics, with a few species in temperate regions (Bayer & Kubitzki, 2003). The Thai species of Hibiscus were enumerated by Phuphathanaphong et al. (1989), totalling 17 species (7 exotic species), and recently 19 species (9 exotic species) were recognized by Pooma & Suddee (2014). Further study of Malvaceae-Malvoideae for the Flora of Thailand by the first author found interesting fertile material of Hibiscus from Surat Thani and Songkhla provinces, southern Thailand, which we describe here as Hibiscus contortus Phuph. & S.Gardner. Borssum Waalkes (1966) recognized 9 sections of tribe Hibisceae and this new species belongs to section Azanza. Most species in this section are trees with broad stipules and palminerved leaves. Hibiscus contortus is most similar to Hibiscus floccosus Mast. which occurs in Peninsular Malaysia

Hibiscus contortus Phuph. & S.Gardner, sp. nov. 

Allied to Hibiscus floccosus Mast. but differs in leaves not lobed, not scabrous (vs angular or lobed, scabrous); pedicel 2–2.5 cm long, jointed (vs 0.5–1 cm long, without joint); petals pale pink to pale orange with darker pink base (vs yellow to orange with red veins from base); stamen filaments 5–7 mm long (vs 2–2.5 mm long).

[Botany • 2017] Kalanchoe hypseloleuce • A New Species (Crassulaceae) from eastern Ethiopia

Kalanchoe hypseloleuce  Friis & M. G. Gilbert

A new species of Kalanchoe, Kalanchoe hypseloleuce Friis & M. G. Gilbert, was found during field work in Ethiopia in 2015, and is established here. It is characterised by its tall stature (2 – 3 m), entire, sessile, lanceolate leaves and pure white flowers with abaxially minutely papillose corolla lobes (otherwise, the plant is glabrous). It is not obviously related to any previously known species, but an earlier, incomplete specimen has been cited as K. prittwitzii Engl. in the literature. K. hypseloleuce was collected on limestone in Acacia-Commiphora woodland and bushland at c. 1400 m a.s.l. It occurs in the southern part of the eastern Ethiopian escarpment in the Arsi and Eastern Harerghe zones of the Oromo Regional State. K. hypseloleuce is documented with images and maps, its climate envelope has been modelled, and a conservation assessment made. With the current level of threat, this could be Vulnerable to Near Threatened (VU-NT). Given the threat from habitat degradation is not imminent, we recommend the species to be listed as Near Threatened (NT).

ETYMOLOGY. Our new epithet, hypseloleuce, is a compound of two Greek adjectives. The first, ψηλός, ή, όν, ‘high, lofty, (metaphorically) stately’, refers to the impressive height of the plant, it being one of the tallest known species of Kalanchoe in Africa. The second, λευκός, -ή, -όν, ‘light, bright, (of colour) white’, refers to the pure white flowers. The connecting vowel –o– is in agreement with Rec. 60G(a2) of the Code (McNeill et al. 2012). The generic name, Kalanchoe Adans. (Adanson 1763: 248), is said to be an adaptation of a Chinese name for a species in the genus (Harvey 1862) or derived from a Hindi word ‘kalanka’, meaning ‘rust’ or ‘spot’ (Quattrocchi 2000). In botanical literature, Kalanchoe is treated as feminine and, in agreement with Art, 23.5 of the Code, the feminine form of the terminal adjective is used.
