N1 - Funding Information:
The field work in Lambir Hills National Park was approved by the Forest Department Sarawak (FDS, Kuch-ing, Malaysia), and conducted in accordance with the Memorandums of Understanding signed between the FDS and the Japan Research Consortium for Tropical Forests in Sarawak (JRCTS) in November 2012. We cordially thank the director and staff of FDS, especially Dr. Engkamat Lading and Mr. Mohamad Bin Kohdi, for permitting our field surveys in the protected area. We also thank JRCTS for obtaining approval from FDS for our research in Sarawak. We are grateful to the following researchers for their help with fieldwork in Southeast Asia: Phourin Chhang (Forest Administration of Cambodia), Phetlasy Souladeth (National University of Laos), Son Van Dang (Institution of Tropical Biology, Vietnam), Hop Tran (University of Ho Chi Minh, Vietnam), Ngoc Van Nguyen and Binh Hoa Tinh (Dalat University, Vietnam), Somran Suddee and Sukid Rueangruea (Forest Herbarium, Thailand), Mu Mu Aung (Forest Research Institution, Myanmar), Bibian Michael Diway (Sarawak Forestry Corporation, Malaysia), Saw Leng Guan, Lim Chung Lu, Yao Tze Leong, and Sam Yen (Forest Research Institute Malaysia), Dedy Darnaedi, Marlina Ardiyani, and Arief Hidayat (Research Center for Biology-LIPI, Indonesia), Anes Syamsuardi (Andalas University, Indonesia), Ngakan Putu Oka (Hasanuddin University, Indonesia), Hidetoshi Nagamasu (Kyoto University, Japan), Akiyo Naiki (University of the Ryukyus, Japan), Hironori Toya-ma (National Institute of Environmental Science, Japan), and Ai Nagahama (Kyushu University, Japan). This work was supported by the Environment Research and Technology Development Fund (S9 & 4-1601) of the Ministry of the Environment, Japan, and by Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research (Grant Number JP15H02640).

N2 - A new species, Actinodaphne lambirensis Tagane, Yahara & N. Okabe (Lauraceae) from Lambir Hills National Park, Miri District, Sarawak, Malaysia, is described and illustrated. It is characterized by gla-brous twigs and leaves, small lamina (4.3–9.2 × 1.7–2.8 cm), and long fruiting peduncles. Because only fruiting specimens were available, the position of A. lambirensis was determined by the phylogenetic trees based on 22 species of Actinodaphne, including the type species of the genus, A. pruinosa Nees, and 11 species of Neolitsea from Southeast Asia using multiplexed inter-simple sequence repeats genotyping by sequencing (MIG-seq). Additionally, a phylogenetic tree was constructed using internal transcribed spacer (ITS) sequences for 36 species of Actinodaphne and 40 species of Neolitsea that include our MIG-seq samples and additional species for which ITS sequences were determined in previous studies. Both the MIG-seq tree and ITS tree supported A. lambirensis as belonging with Actinodaphne.
