Two new species and a new species record of Aglaia (Meliaceae) from Indonesia

Abstract

Two new species of Aglaia from Indonesia are described, Aglaia monocaula restricted to West Papua, and Aglaia nyaruensis occurring on Borneo (Kalimantan, Brunei, Sabah and Sarawak). A phylogenetic analysis using nuclear ITS and ETS, and plastid rps15-ycf1 sequence data indicates that the two new species of Aglaia are also genetically distinct. Aglaia monocaula belongs to sectionAmoora, while A. nyaruensis is included in section Aglaia. A dichotomous key, drawings and three-locus DNA barcodes are provided as aids for the identification of the two new species of Aglaia. In addition, the geographic range of Aglaia mackiana (section Amoora) is expanded from a single previously known site in Papua New Guinea to West Papua, Indonesia.

Confirmed polyphyly, generic recircumscription and typification of Dysoxylum (Meliaceae), with revised disposition of currently accepted species

“…For some samples, ITS was amplified in two parts, ITS1 and ITS2, using primers 17S_m and ITS_R1 for ITS1, and ITS_F1 and 26SE_m for ITS2, with the same annealing temperature as for the entire ITS region (Grudinski & al., 2014a). For ETS, 18S-E (Baldwin & Markos, 1998) and MEL1 (Pannell & al., 2020) were used, with the same annealing temperature as for the ITS amplification. For the trnL-F region, PCR was done in two parts, using the primer pair trnLF_c and trnLF_d for the first part, and trnLF_e and trnLF_f (Taberlet & al., 1991) for the second part of trnL-F, with an annealing temperature of 54°C.…”
