    [Botany • 2018] Aspidistra laongamensis (Asparagaceae) • A New Species from Salavan Province, southern Laos

    Aspidistra laongamensis  C. R. Lin & X. Y. Huang 

    in Huang, Sosoulthanee, Ke, Xu, Sydara, et al., 2018.

    Abstract
    Aspidistra laongamensis C. R. Lin & X. Y. Huang, a new species of the Asparagaceae from Saravan Region, Laos, is described and illustrated. The new species is similar to A. lubae Aver. et Tillich in the perianth shape, but differs by the creeping rhizome, externally yellowish white perianths with internall yellow lobes, and the flat, glabrous stigma.The new species is also similar to A. nankunshanensis Yan Liu & C. R. Lin in the ovate-triangular, internally yellow perianth lobes, but differs by its urceolate perianth with an internally purplish red tube, and stamens inserted in the middle of the perianth tube, and mushroom-shaped pistil. Aspidistra laongamensis is currently known only from Laongam city, southern Laos.

    [Crustacea • 2018] Teretamon kempi • A New Species of Freshwater Crab of the Genus Teretamon Yeo & Ng, 2007 (Decapoda: Brachyura: Potamidae) from Arunachal Pradesh, northeastern India

    Teretamon kempi
    Mitra, Payra & Chandra, 2018


    Abstract
    A new species of potamid crab of the genus Teretamon Yeo & Ng, 2007, is described from Namdapha Tiger Reserve in Changlang district of Arunachal Pradesh, India. The new species, Teretamon kempi n. sp., can be distinguished from its congeners by a distinct combination of carapace and gonopod characters: a relatively high carapace with a bilobed frontal margin; subquadrate sixth abdominal somite with nearly parallel lateral margins; and a relatively small G1 terminal segment with a semicircular to bluntly triangular dorsal flap. All known Teretamon species are compared with the new species, and a key for this genus is provided.
