 Acranthera collina C. W. Lin & C. H. Lee

in Lin & Lee, 2019

 Acranthera collina (Rubiaceae), a new species from Sarawak, Malaysia, on the island of Borneo, is described and illustrated. Acranthera collina resembles A. bullata Merr. but is easily distinguished by its ca. 10 pairs of lateral veins (vs. 13–15 pairs), 6-merous flowers (vs. 5-merous), golden yellow corolla (vs. red) and anthers ca. 5 mm long (vs. 10 mm long).

Key words: Acranthera, Borneo, new species, Rubiaceae, Sarawak

Acranthera collina C. W. Lin & C. H. Lee, sp. nov.

Acranthera collina resembles A. bullata Merr. (1937: 284) in having bullate obovate leaves, a short stature and an erect habit, but differs in having fewer lateral veins (10 or 11 pairs in A. collina vs. 13–15 pairs in A. bullata), 6-merous flowers (vs. 5-merous), golden yellow corolla (vs. red), and smaller anthers (ca. 5 mm long in A. collina vs. 10 mm long).

Distribution and habitat. Endemic to Sarawak. Currently known only from the Serikin area (Fig. 1); lowlands in mixed dipterocarp forest on riverbank and at base of limestone hills in semi-shaded and consistently humid areas, ca. 100 m elevation. 

Etymology. the epithet collina refers to the lowland mountains where Acranthera collina was collected.

[Invertebrate • 2019] New Species of Lissodendoryx Topsent, 1892 (Demospongiae, Poecilosclerida, Coelosphaeridae) and Myxilla Schmidt, 1862 (Demospongiae, Poecilosclerida, Myxillidae) from the Northeast Pacific

Myxilla (Myxilla) austini 

Ott, Reiswig, et al., 2019. 

Collections of sponges by the late Dr. William C. Austin and the authors (N. McDaniel, R. Harbo and B. Ott) provided material for descriptions of new species from two genera of Poecilosclerida for shallow waters of Southern British Columbia, Canada and Northern Washington, USA: Lissodendoryx and Myxilla. There have been no new species of these two genera described for the Northeast Pacific since Laubenfels’ work in central California (Laubenfels 1930, 1932) and Lambe’s reports in 1893 to 1895 for Geological Survey of Canada sponge collections from British Columbia, Canada to the Bering Sea. We describe three new species of Lissodendoryx (Lissodendoryx) (Demospongiae, Poecilosclerida, Coelosphaeridae) and one new species of Myxilla (Myxilla) (Demospongiae, Poecilosclerida, Myxillidae): L. (L.) barkleyensis n. sp., L. (L.) littoralis n. sp., L. (L.) toxaraphida n. sp. and M. (M.) austini n. sp. Lissodendoryx (L.) barkleyensis n. sp. is cave-dwelling, has acanthostyles 112–260 µm, tornotes 107–177 µm, arcuate isochelas 8–28 µm and two sizes of sigmas 18–29, 26–55 µm. Lissodendoryx (L.) littoralis n. sp. fistulate habitus is adapted to muddy substrates similar to some Polymastia species also found commonly in the Northeast Pacific. It has subtylostyles 185–336 µm, tylotes 112–229 µm, arcuate isochelas 11–23 µm, and sigmas 30–75 µm. Lissodendoryx (L.) toxaraphida n. sp. is the only described Lissodendoryx species with raphides shaped like toxas. It has acanthostyles 140–286 µm, tornotes 143–195µm, arcuate isochelas 18–34 µm and toxiform raphides 65–156 µm. Myxilla (M.) austini n. sp. has a fistulate habitus and both tornote and tylote megascleres. It appears to be tolerant of low oxygen environments. Myxilla (M.) austini n. sp. has smooth to sparsely spined styles 193–353 µm, tylotes 153–221 µm, tornotes 174–260 µm, two sizes of anchorate isochelas 13–27, 42–81 µm, and two sizes of sigmas 13–47, 33–78 µm. All specimens were collected from shallow water (intertidal to 25 m).

[Entomology • 2019] Genus Cheilonycha Lacordaire, 1842 (Coleoptera: Cicindelidae) [Taxonomic and Nomenclatorial Revision within the Neotropical Genera of the Subtribe Odontocheilina W. Horn in A New Sense—22]

Cheilonycha auripennis auripennis (Lucas, 1857)

in Moravec, 2019. 

Taxonomic and nomenclatorial revision of the genus Cheilonycha Lacordaire, 1842 with type species Cheilonycha chalybea (by original monotypy), based on Cicindela chalybea Dejean, 1825, is presented. It is concluded here that a subsequent type designation by Horn (1910), who without any explanation mentioned Ch. auripennis (Lucas, 1857) as the type species of the genus, was unjustified and must be considered invalid according to ICZN (1999). Examinations of type specimens have revealed that Cheilonycha auripennis sensu auctorum (sensu Horn 1922 and subsequent authors) is a complex of taxa. As a result, one new subspecies of Ch. auripennis (Lucas, 1857) and one new species of the genus are described and the following taxa of Cheilonycha are recognized and presented here: Ch. chalybea (Dejean, 1825), Ch. a. auripennis (Lucas, 1857), Ch. a. chiquitosiana ssp. nov. and Ch. bucephalauripennis sp. nov. Type specimens of Ch. a. angustedilatata (W. Horn, 1922) based on Odontochila (Chilonycha) auripennis angustedilatata W. Horn, 1922, proved to be fully conspecific with the type specimens of Ch. auripennis based on Cicindela auripennis Lucas, 1857. Consequently, Ch. a. angustedilatata syn. nov. is treated here as a junior synonym of Ch. a. auripennis. The history of the taxonomy of these taxa, their distribution and biology, including photographs of the termitophilous habitat, relevant lectotype designations, descriptions (redescriptions respectively) and illustrations in colour photographs of the habitus, diagnostic characters and variability are provided.

DOI: 10.11646/zootaxa.4693.1.1 

Data on the ichneumonid parasitoid wasps of the subfamily Pimplinae from Ukraine are summarized. The fauna of the Ukrainian pimplines numbers 35 genera and 146 species equivalent to almost 63% of European fauna. Twenty-four species are recorded from Ukraine for the first time. Pimpla femorella Kasparyan, 1974 is a first record for Western Palaearctic. The highest species richness (91–94 spp.) occurs in Ivano-Frankivsk and Transcarpathian Regions situated mostly in the Carpathian Mountains basin. The Carpathian Montane Forests were found to be the most species rich (112 species) of the six ecoregions present in Ukraine. The flight period of Pimplinae-wasps in Ukraine lasts nine months with a maximum number of species collected in June and genera in July respectively.

Despite being known from every continent, the geological record of pterosaurs, the first group of vertebrates to develop powered flight, is very uneven, with only a few deposits accounting for the vast majority of specimens and almost half of the taxonomic diversity. Among the regions that stand out for the greatest gaps of knowledge regarding these flying reptiles, is the Afro-Arabian continent, which has yielded only a small number of very fragmentary and incomplete materials. Here we fill part of that gap and report on the most complete pterosaur recovered from this continent, more specifically from the Late Cretaceous (~95 mya) Hjoûla Lagerstätte of Lebanon. This deposit is known since the Middle Ages for the exquisitely preserved fishes and invertebrates, but not for tetrapods, which are exceedingly rare. Mimodactylus libanensis gen. et sp. nov. differs from the other Afro-Arabian pterosaur species named to date and is closely related to the Chinese species Haopterus gracilis, forming a new clade of derived toothed pterosaurs. Mimodactylidae clade nov. groups species that are related to Istiodactylidae, jointly designated as Istiodactyliformes (clade nov.). Istiodactyliforms were previously documented only in Early Cretaceous sites from Europe and Asia, with Mimodactylus libanensis the first record in Gondwana.

Branch-based definition: The most inclusive clade containing Istiodactylus latidens, but not Anhanguera blittersdorffi.

Diagnosis: Slender-built lanceodontian pterodactyloids with the following synapomorphies: mandibular rostral end pointed, teeth confined to the anterior half of the jaws, and labiolingually compressed crowns with a cingulum.

Included taxa: Istiodactylidae, Mimodactylidae, and Hongshanopterus lacustris.

Mimodactylidae clade nov.

Branch-based definition: The most inclusive clade containing Mimodactylus libanensis gen. et sp. nov., but not Istiodactylus latidens, Ikrandraco avatar, and Anhanguera blittersdorffi.

Diagnosis: Istiodactyliforms with cone-shaped teeth, crowns with a slight labiolingual compression, and sternal articular surface of the coracoid slightly concave.

Included species: Haopterus gracilis and Mimodactylus libanensis gen. et sp. nov.

Mimodactylus libanensis gen. et sp. nov.

Etymology: Mimodactylus, from the acronym MIM (Mineral Museum) for the museum housing the specimen, in recognition of both the museum and the wishes of the anonymous philanthropist who facilitated the acquisition of the specimen thus keeping it in Lebanon, and the Greek ‘dactylos’ (δάκτυλος), meaning digit; libanensis from Lebanon, where the specimen was found.

Holotype: Almost complete skeleton, including the skull and lower jaw, housed at the Mineral Museum (MIM) of Beirut, Lebanon, MIM F1. Cast at the University of Alberta, Edmonton and Museu Nacional/UFRJ (MN 7216-V).

Locality and horizon: Hjoûla Lagerstätte of the Sannine Limestone (late Cenomanian), near the town of Hjoûla located 35 km NNE of Beirut and 10 km inland from Jbail, Lebanon.

Diagnosis: Mimodactylid with the following autapomorphies: humerus with a rectangular deltopectoral crest; humerus smaller than half the length of the second phalanx of the wing finger (hu/ph2d4 < 0.5). This species can be further distinguished from other ornithocheiroid pterodactyloids by the following combination of characters: discrete palatal ridge; 11 and 10 cone-shaped teeth on each side of the upper and lower jaws, respectively; scapula slightly longer than coracoid; humerus much longer than femur (hu/fe ~1.3); deltopectoral crest extends for around 40% of the humerus shaft length (see Supplementary Information for further details and measurements).

[Botany • 2019] Chrysosplenium macrospermum (Saxifragaceae) • A New Species of Chrysosplenium from Northeastern China

Chrysosplenium macrospermum Y.I.Kim & Y.D.Kim

in Kim, Shin, Lee, et al., 2019. 
천지괭이눈 | 天池金腰 ||  DOI: 10.3897/phytokeys.135.39036

This study describes and illustrates Chrysosplenium macrospermum Y.I.Kim & Y.D.Kim, a new plant species from Changbaishan Mt. (Baekdusan Mt.) in northeastern China. The species is most similar to Chrysosplenium valdepilosum in the series Pilosa but is readily distinguishable by short arching sterile branches, multiple (up to 3) flowering stems, and smooth surfaced seeds (without tubercles), which are ca. 30–50% larger than those of other members in the series.

Keywords: Saxifragales, seed morphology, sterile branch, taxonomy

Chrysosplenium macrospermum Y.I.Kim & Y.D.Kim, sp. nov.

Diagnosis: Chrysosplenium macrospermum is most similar to Chrysosplenium valdepilosum (Ohwi) S.H. Kang & J.W. Han, 2011 (see Han et al. 2011), but the former is readily distinguishable by short arching sterile branches, multiple (up to 3) flowering stems, and smooth surfaced seeds (without tubercles), which are ca. 30–50% larger than those of other members in the series Pilosa (Figure 3).

Etymology: The specific epithet of the new species refers to the distinctly larger size of the seeds compared with those of other members in the series Pilosa.

Vernacular name: Cheon Ji Gwaeng I Nun (Korean pronunciation); 천지괭이눈 (Korean name), Tiān Chí Jīn Yāo (Chinese pronunciation); 天池金腰 (Chinese name)


Distribution: Chrysosplenium macrospermum is only known from Changbaishan Mt. in Jilin Province of China, at an elevation of ca. 2,600 m. To date, only a few subpopulations with approximately 5,000 individuals have been discovered near Tianchi Crater Lake. In the absence of additional data, we presently score it as Data Deficient (DD) according to the IUCN Red List criteria (IUCN 2001).

Ecology: Chrysosplenium macrospermum occurs in alpine tundra, where it grows in humid and semi-shaded areas near the Tianchi volcanic crater along with Papaver radicatum var. pseudoradicatum (Kitag.) Kitag., Bistorta ochotensis Kom., Micranthes laciniata (Nakai & Takeda) S. Akiyama & H. Ohba, Sedum rosea (L.) Scop., and Pedicularis verticillata L. The flowering period of this species is from late May to early July, and the fruiting period is from July to August.

[Paleontology • 2020] The Oldest Lambeosaurine Dinosaur from Europe: Insights Into the Arrival of Tsintaosaurini

 Lambeosaurine Dinosaur from the Upper Cretaceous northeastern Spain.

Hollow-crested lambeosaurine hadrosaurids represent one of the latest and most rapid radiations of ornithischian dinosaurs, attaining a nearly global distribution during the Late Cretaceous. Although their presence in Europe is well documented, there are questions about the origin and timing of their arrival in this continent. The analysis of old and newfound lambeosaurine specimens from the Els Nerets locality (eastern Tremp Syncline, northeastern Spain) have shown that the ornithopod dinosaurs from this classic site belong to Lambeosaurinae. Recent chronostratigraphic data places the locality in the lower Maastrichtian, implying that the Els Nerets lambeosaurine is the first occurrence of the clade in Europe. The Els Nerets lambeosaurine exhibits some noticeable pelvic features only shared with the Asian taxon Tsintaosaurus spinorhinus and thus we hypothesize a close taxonomic affinity between the lambeosaurine from Els Nerets and the Eurasian Tsintaosaurini. Members of this tribe would have dispersed into the Ibero-Armorican Domain not later than the early Maastrichtian, coexisting with endemic dinosaurian groups for some time.

[Herpetology • 2019] Cyrtodactylus muangfuangensis • A New Species of Cyrtodactylus (Squamata: Gekkonidae) from Vientiane Province, northern Laos

Cyrtodactylus muangfuangensis  
Sitthivong, Luu, Ha, Nguyen, Le & Ziegler, 2019

A new species of the genus Cyrtodactylus from Vientiane Province, northern Laos is described based on morphological and molecular data. Cyrtodactylus muangfuangensis sp. nov. can be distinguished from remaining congeners by the following combination of characters: maximum SVL 83.9 mm; dorsal pattern consisting of dark nuchal loop, nape band and five dark transversal bands between limb insertions; intersupranasals two; dorsal tubercles present on occiput, body, hind limbs and tail base; 15 or 16 irregular dorsal tubercle rows at midbody; lateral folds clearly defined, without interspersed tubercles; 31–37 ventral scales between ventrolateral folds; six precloacal pores and 15 femoral pores in males, which are interrupted by six to eight poreless scales; six precloacal pitted scales plus in total 10–15 pitted femoral scales in females, which are separated by six to eight poreless scales; enlarged precloacal and femoral scales present; two or three postcloacal tubercles; median subcaudal scales transversely enlarged. In molecular analyses, the new species is strongly supported as a member of the Cyrtodactylus phongnhakebangensis species group, and weakly corroborated as a sister taxon to C. pageli. Pairwise genetic comparison shows that it is at least 18% divergent from other congeners in the species group based on a fragment of the mitochondrial cytochrome C oxidase subunit I gene.

Ornithocheirus wiedenrothi, from the Hauterivian (Early Cretaceous of Germany), is a taxon represented by three-dimensional remains of the lower jaw and wing elements. Its phylogenetic affinities have for long been elusive, though several works had already pointed out that it probably did not belong within the wastebasket genus Ornithocheirus. In the present contribution, we redescribe this species, assigning it to the new genus Targaryendraco and offering updated morphological comparisons. Subsequently, we present a phylogenetic analysis in which we recover a clade formed by TargaryendracoAussiedracoBarbosaniaAetodactylusCamposipterus and Cimoliopterus. This newly recognised clade is interesting in being quite cosmopolitan and spanning from the Hauterivian to the Cenomanian, like its sister-group, the Anhangueria. The recognition of this clade helps fill the temporal gap between the Anhangueria and Cimoliopterus, and also demonstrates that the diversity of Cretaceous toothed pterosaurs was higher than previously thought.

Targaryendraconidae new clade 

Type genus: Targaryendraco gen. nov. 
Content: Targaryendraco, Aussiedraco and Barbosania.

Targaryendraco gen. nov. 

Etymology A combination of Targaryen and draco (from the Latin word for dragon), in reference to the fictional dragons of the saga A Song of Ice and Fire that exhibit dark-coloured bones. This refers to the dark colour of the type specimen of Targaryendraco wiedenrothi comb. nov., as well as to the classic association between pterosaurs and dragons (e.g. Seeley 1870). This reference also honours the fact that pterosaurs have inspired some biological aspects of the dragons featured in the novels.
