    Abstract
    The pitviper species Trimeresurus caudornatus was recently described based on only two specimens from Nabang Town, Yingjiang County, Yunnan Province, China. Here, we provide additional data on this species based on a re-examination of 19 preserved specimens, 16 specimens reported in earlier literature sources, and additional photo-documented records from northern Myanmar (Burma) and adjacent China. All new specimens were previously identified as Trimeresurus albolabris sensu lato or Trimeresurus septentrionalis sensu lato. Molecular analyses based on mitochondrial DNA supported the morphological findings in establishing conspecificity with T. caudornatus. The newly identified specimens have a pairwise distance of only 0.4–2.6% from those of the type series of T. caudornatus (based on the cytochrome b gene). Based on these findings, we confirm the presence of T. caudornatus from Myanmar and update its diagnostic characters and distribution. We suggest the species should be considered as Least Concern (LC) following the IUCN’s Red List categories. Further studies reassessing the populations of the Trimeresurus albolabris complex are required.

    [PaleoBotany • 2023] First Recognition of the Extinct Eudicot Genus Palibinia in North America: Leaves and Fruits of Palibinia comptonifolia (R.W.Br.) comb. nov. from the Eocene of Utah and Colorado, USA


    Palibinia comptonifolia (R.W.Br.) comb. nov. 

    in Manchester, Judd et Kodrul, 2023. 
     
    Abstract
    Newly investigated leafy twigs bearing axillary fruits from the Eocene Parachute Creek Member of the Green River Formation in eastern Utah, USA, have provided more information on the species previously attributed to the Proteaceae as Banksia comptonifolia R.W.Br. The leaves are simple, estipulate with short petioles, and elongate laminae with prominent angular nonglandular teeth. The laminae have a thick midvein and pinnate craspedodromous secondaries, and are distinctive in the presence of a thick, often coalified, marginal rim. Vegetative and reproductive buds occur in the axils of the leaves. These features indicate that the species belongs to Palibinia Korovin—an extinct Eudicot genus previously known only from the Paleogene of Asia and Europe. Small pedicellate ovoid fruits 1.5–2.2 mm wide are borne in fascicles of three and are seen to be capsules with four apical valves. Despite the specific epithet referring to similarity of the foliage to that of Comptonia (Myricaceae), the fasciculate inflorescence organization with axillary flowers is quite distinct from the catkins characteristic of that family. Assignment to Banksia or other Proteaceae with complex inflorescences and follicular fruits is also problematic. Additionally, MacGinitie′s transfer of the species to Vauquelinia of the Rosaceae is contradicted by the lack of stipule scars on the twig and by differences in leaf venation and floral morphology. We transfer the species to Palibinia comptonifolia (R.W.Br.) comb. nov., but its familial affinity within the Pentapetalae remains uncertain. This new occurrence augments records from the Paleogene of Turkmenistan, Kazakhstan, China, England, and Germany.

    [Entomology • 2023] Lathrobium neostygium • A New troglobiontic Rove Beetle (Coleoptera: Staphylinidae: Paederinae) from central Honshu, Japan


    Lathrobium neostygium Senda, 2023 


    Abstract 
    A new troglobiontic species, Lathrobium neostygium sp.n. (Coleoptera: Staphylinidae: Paederinae), is described from Gifu Prefecture, central Honshu, Japan. Photographs of the male and female habitus, of the aedeagus and of the type locality are provided. This finding represents the easternmost record of a Japanese troglobiontic species of Lathrobium GRAVENHORST, 1802. The L. nomurai species group is redefined, and a checklist of the species of this group is provided

    Key words: Coleoptera, Staphylinidae, Paederinae, Lathrobium, subterranean biodiversity, East Asia, Japan, endemic species, new species, taxonomy


     Lathrobium neostygium:
     A–B) habitus of A) male, holotype and B) female, paratype, C) abdominal ventrites of male, showing secondary sexual characters, D) type locality.

    Photographs by Y. Senda (A–C) and K. Kawamura (D).

    Lathrobium neostygium sp. n.

      DIAGNOSIS: The new species is similar to Lathrobium tanakai described from Kii Peninsula (WATANABE 1998) in external and aedeagal features, but differs from it in the following characteristics: 1) lateral sides of the posterior excision asymmetrically produced in the caudal margin of male abdominal ventrite VIII (feebly and symmetrically produced in L. tanakai); 2) apical projection of aedeagal dorsal sclerite comparatively robust, with rounded apex (slender, with pointed apex in L. tanakai); 3) apical projection of paramere distinctly curved dorsad at about 1/5 (slightly curved dorsad at about 1/6 in L. tanakai).

    ETYMOLOGY: The epithet is a combination of the traditional Japanese geographical name “Neo” (an area in the western part of Gifu Prefecture, where the new species was collected) and the Latin adjective “stygius” (stygian, being part of the underworld). The name is used as an adjective.

    [Botany • 2024] Meriania judithiae (Melastomataceae: Merianieae) • A New Species from southeastern Ecuador


    Meriania judithiae  

    in Jiménez, Iturralde, Mendoza, Ocupa-Horna et Garzon-Suarez, 2024.
     
    Abstract
    Meriania judithiae, a new species from the southeast of Morona Santiago in Ecuador, is described and illustrated. With this new addition, the number of species of the genus increases to 33 in this country. Meriania judithiae has leaves with a attenuate base extending down the petiole as wings, multiflorous inflorescences with sub-umbellate paraclades, pink-orange campanulate flowers, the calyx with conical projections, and isomorphic stamens with connectives prolonged below the thecae. It is compared with M. cuneifolia, its most similar species which shares the distant supra-basal venation and gradually narrowing base of the leaves. In addition, the taxonomic similarities of the new entity are discussed and information about its distribution, habitat, and conservation status is provided.

    Diagnosis. This species is most similar to Meriania cuneifolia subsp. cuneifolia but differs by the sparse furfuraceous indumentum (vs. hirsute), the much shorter petioles 0.3–1.0 cm long (vs. 2.0–3.0 cm long), the leaf blades with attenuate bases extending into the petiole as wings (vs. long-cuneate), the shorter calyx lobes 0.5–1.3 mm long (vs. 8.5 mm long) each with a conical projection that does not surpass the apex of the lobe (vs. distinct claw-shaped projections extending further the lobes), and the isomorphic stamens (vs. dimorphic).  

    Etymology:—The new species is named after Judith A. Steck, mother of David R. Goucher who has been actively supporting botanical research, environmental education and conservation in the south of Morona Santiago province, Ecuador.
