| 5:51a | [Botany • 2017] Brownlowia latifiana • A New Species (Malvaceae: Brownlowioideae) from Terengganu, Peninsular Malaysia
Abstract A new species, Brownlowia latifiana (Malvaceae-Brownlowioideae), endemic to Terengganu, Peninsular Malaysia, is described and illustrated. This new species has most of its morphological characters that are related to those of the genus Jarandersonia. Therefore, a standard morphological taxonomic revision and morphometric analysis were carried out to assess the status of Brownlowia latifiana. Results of the morphometric analysis based on morphological characters showed that Brownlowia latifiana is embedded within the clades of Brownlowia but distanced from the clades Jarandersonia. Brownlowia formed a distinct clade in the clustering tree well separated from the Jarandersonia. A distribution map and a conservation assessment using the IUCN Red List categories and criteria are provided. Keywords: Conservation, endemic, flora, Malaysia, taxonomy, Malvaceae, Eudicots
Brownlowia latifiana R.C.K.Chung, sp. nov. Type:— PENINSULAR MALAYSIA. Terengganu: Dungun, Jerangau Forest Reserve, buffer zone by the stream of Compartment 95, 65 m altitude, 21 July 2009 (flowers and fruits), Y.C. Chan & C.L. Lim FRI 65055 (holotype KEP [barcode 246218]; isotypes A, K). Brownlowia latifiana is closely related to B. argentata and B. tersa in leaf texture, type of indumentum and other flower and fruit characters. However, the former differs from the latter, B. argentata and B. tersa, by its narrowly elliptic leaves (vs. ovate to broadly ovate or lanceolate), glabrous beneath (vs. densely covered with scales), 10−20 pairs lateral veins (vs. 4−10), large transversely ellipsoid fruits (vs. small depressed obovoid), absence of androgynophore (vs. presence and elongated to 6 mm long, 3 mm thick), persistent calyx lobes (vs. absent), and thick fruit stalk (vs. thin stalk). The main morphological differences between these three species are shown in Table 3. ..... Etymology:— This species is named after the current Director-General of Forest Research Institute Malaysia (FRIM), Dato’ Dr Abd. Latif bin Mohmod, for his contributions in securing fund of RM7.6 million for the Project of Safeguarding the Forest Plant Diversity of Peninsular Malaysia under the Ninth Malaysian Plan; successfully in acquiring the ownership of FRIM land area of 544.3 ha from the Selangor State Government in 2007; and in obtaining the recognition for FRIM as the Natural Heritage Site in 2009 and the National Heritage in 2012. Distribution and habitat:— This species is endemic to Peninsular Malaysia, known from Jerangau Forest Reserve and Sg. Jerangau in Dungun, Terengganu. It occurs in undulating and riverine areas of lowland dipterocarp forest on clay sandy and alluvial soils at about 65 m elevation.

| 4:39p | [Herpetology • 2017] Cyrtodactylus tambora • A New Small Bent-toed Gecko of the Genus Cyrtodactylus (Squamata: Gekkonidae) from the Lower Slopes of Mount Tambora, Sumbawa Island, Indonesia
Abstract We describe the sixth species of bent-toed gecko from the Lesser Sunda Islands, Indonesia. This species was first collected on the banks of the Oi Marai River on the low northern slopes of Gunung (Mount) Tambora on Sumbawa Island. The new species is differentiated from Greater Sunda Islands (including Sulawesi) and Lesser Sunda Islands congeners by having the following unique combination of characters: (1) two scales between the second pair of postmentals in contact with the first pair; (2) dorsal surface of antebrachium tuberculate; (3) no tubercles on dorsal surface of brachium; (4) dorsal surfaces of thigh and crus tuberculate; (5) 18 irregularly aligned, longitudinal rows of keeled tubercles at midbody; (6) 26–27 paravertebral tubercles; (7) 40 ventral scales between indistinct ventrolateral folds; (8) 16–17 fourth-toe subdigital scales; (9) a continuous enlarged precloacal and femoral scales present, with the enlarged femoral scales arranged in three rows; (10) males with five to six precloacal pores, with four larger pores situated in a short groove; (11) femoral pores absent in both sexes; (12) lack of transversely enlarged subcaudal scales; and (13) 7–9 irregular, paired black blotches on the body.

Cyrtodactylus tambora sp.nov. English common name: Tambora Bent-toed Gecko Indonesian common name: Cicak Jari-Lengkung Tambora Etymology. The species name tambora is a noun used in apposition. It is used not only to identify the collection locality, but also to commemorate the large eruption of Gunung Tambora in 1815, which no doubt significantly realigned the local natural world on its slopes.
