    Abstract
    Ajorama Otte, 1988 is a genus of Landrevinae subfamily endemic to the Philippines, with only two species described: A. balatukanis Otte, 1988 and A. siargaoensis (Tan, Gorochov, Baroga-Barbecho & Yap, 2019). In a recent fieldwork in Northern Mindanao, Philippines, a new species of Ajorama was discovered and is described here: Ajorama chelatoides sp. nov. It is most readily distinguished from other congeners by the male genitalia having a chelated (crab-like) pseudepiphallic lophi [posterolateral epiphallic lobe]. This represents the third described species of Ajorama. This genus remains endemic to Mindanao. A new locality record (Lanao del Norte, Iligan City) for Duolandrevus (Bejorama) gingoogus Otte, 1988, previously known from Mt. Pomalith, Misamis Oriental, is also reported.

    [Botany • 2019] Rehderodendron truongsonense (Styracaceae) • A New Species from Vietnam


    Rehderodendron truongsonense  P.W. Fritsch, W.B. Liao, & W.Y. Zhao,

    in Zhao, Fritsch, Do, Fan, Yin, Penneys, Swenson et Liao, 2019. 

    Rehderodendron truongsonense, a new species from Vietnam, is described and illustrated. In the treatment of the Styracaceae for the Flore du Cambodge, du Laos, et du Viêtnam, specimens of this species were recognized as R. macrocarpum Hu. These specimens clearly differ from R. macrocarpum, however, as well as from all other species of Rehderodendron (where these characters are known) by, e.g., an evergreen versus deciduous habit, fewer secondary veins of the leaf blade, shorter inflorescences and corolla lobes, large and conspicuous lowermost bracteoles, the presence of eight ovules per carpel, and a fruit with ca. 10 to 20 ribs that are indistinct. Phylogenetic analysis based on five chloroplast DNA regions (clpP-psbB, ndhD-psaC-ndhE-ndhG, rpl22-rps19, rps18-rpl20, and psbI-trnS-GCU) placed the new species as nested within Rehderodendron and sister to R. gongshanense. This new species is endemic to the Truong Son Mountain Range, from which the epithet is derived, and we assign it an IUCN Red List preliminary status as Near Threatened.

    [Funga • 2025] Clavaria divergens, C. orientalis & C. tongdaoensis • Morphological and Multi-locus Phylogenetic Analyses reveal Three New branched Species of Clavaria (Agaricales: Clavariaceae) from China

    P. Zhang & Ju. Yan,

    in Yan, Xiong, Yang, He, Zhang et Liao, 2025.

    Abstract
    Based on morphological and molecular evidence, 12 specimens have been identified as belonging to three previously unrecognized species of Clavaria, which are here described as C. divergens, C. orientalis, and C. tongdaoensis. Clavaria divergens is characterized by its branched, white basidiomata. Clavaria orientalis and C. tongdaoensis are very similar to C. zollingeri in the field. However, C. orientalis is distinguished by its more robust branches, while C. tongdaoensis differs by its varied or paler color of basidiomata. A concatenated sequence dataset (ITS-nrLSU-RPB2) was used for multi-locus phylogenetic analysis. The phylogenetic tree of Clavaria showed that the three branched species each formed a distinct lineage with strong support. A key to the known branched species of Clavaria in China is provided.

    [Herpetology • 2020] Nidirana occidentalis • A New Species of Nidirana from the N. pleuraden Group (Anura: Ranidae) from western Yunnan, China

    Nidirana occidentalis  Lyu, Yang & Wang,

     in Lyu, Chen, Yang, ZENG, J. Wang, Zhao, Wan, Pang et Y.-Y. Wang, 2020.
     
    Abstract
    The Music Frog genus Nidirana was recently resurrected as a distinct genus and contains 14 species distributed in subtropical eastern and southeastern Asia. The species diversity of Nidirana is dramatically underestimated, and half of its species was described in the last five years. In this study, Nidirana occidentalis sp. nov., a new species of Music Frog from western Yunnan, China, is proposed based on morphological and molecular evidences. The new species was previously misidentified as N. pleuraden, but can be distinguished from the true N. pleuraden from eastern Yunnan, and all other congeners, by a combination of morphological characteristics, and significant divergence in the mitochondrial genes (≥ 5.1% in 16S and ≥ 8.9% in CO1). Nidirana occidentalis sp. nov. is assigned to the N. pleuraden group on the basis of morphological characters, but its phylogenetic placement remains unresolved due to weak branch support. Geographically, these two species are isolated by the Red River in Yunnan, supporting the hypothesis that the Red River is an important geographical barrier that drives speciation in flora and fauna. Nidirana occidentalis sp. nov. represents the second species of N. pleuraden group and the 15th species of the genus.
