| 1:49a | [Mollusca • 2022] Nitidotellina hachiensis • A New Species (Bivalvia: Tellinidae) from the Seto Inland Sea, between Honshū and Shikoku, western Japan
ABSTRACT A new species of tellinid, Nitidotellina hachiensis, is described from Japan. The shell of this species is characterised by a pair of strong keels that run from the beaks to the posterior end and forms a prominent posterior notch. The recent individuals are found only in the Seto Inland Sea (Okayama, Hiroshima, Yamaguchi and Ehime prefectures), while the one fossil record so far known is from the Chibanian (middle Pleistocene) Toyohashi Formation in Aichi Prefecture, central Honshū. Living individuals are uncommon and mainly found living in sandy mud bottoms from the low tide line down to the subtidal zone in the inner parts of large bays. It can be regarded as endangered due to the recent habitat loss and water pollution of inner bay environments.

| 3:37p | [Botany • 2022] Lepidagathis mahakassapae (Acanthaceae: Barlerieae) • A New Species from the high elevated Lateritic Plateau of Northern Western Ghats of Maharashtra, India
Abstract Lepidagathis mahakassapae sp. nov., a monocarpic and endemic species of Acanthaceae, is described from Western Maharashtra, India. The new species is allied to L. sabui from Konkan, Maharashtra, but differs by having oblanceolate acuminate leaves, pubescent terminal elongated spikes, large floral but small sterile bracts and lanceolate broader segment of the bracteole. The stems of L. mahakassapae grows up to 250 cm in length while a few other prostrate species grows up to this length. Illustrations and colour photographs are provided for ease of identification.

| 3:46p | [Herpetology • 2022] Echinotriton raffaellii & Tylototriton houi • Towards Completing the Crocodile Newts’ Puzzle with All-inclusive Phylogeographic Resources
Abstract Crocodile newts (Echinotriton and Tylototriton) are emblematic of the biodiversity of South-East Asia. In this study, we provide an account of their evolution, diversity and phylogeography based on mitochondrial (16.2 kb) and nuclear sequences (3.2 kb), combining barcoding data from nearly 1200 specimens collected over ~180 localities, representative of all lineages known to date. While phylogenies of nuclear data lacked resolution, the mitochondrial tree showed dynamic allopatric speciation that followed climate cooling during the last 10 million years, a pattern shared with many other tropical and subtropical amphibians. In crocodile newts, this implies weak dispersal and local adaptation as contributing factors of isolation, and was accompanied by macro- and micro-evolutionary changes in reproductive behaviours. Specifically, our resolved phylogeny of Tylototriton allowed the tracing of a major shift from conserved habits of terrestrial clutch-spawning towards more plastic strategies involving both aquatic and land spawning of single eggs. Using this framework, we then revised the taxonomy of crocodile newts by describing a new subgenus and two new species. Our study provides a basis to guide future phylogeographic, speciation and conservation research on these iconic amphibians.
