We describe two novel diminutive species of Calamus, C. carsicola and C. warayanus, from the islands of Samar and Siargao, Philippines. Despite their respective similarities with the more variable and widely-distributed C. discolor and C. microsphaerion, both new taxa are distinctive by a suite of unique morphological character combinations. These new rattans are both characterized by their very slender clustering habit and are apparently restricted to forests over limestone. Relevant taxonomic notes and preliminary IUCN conservation status are herein provided.

Recent botanical explorations in the province of Palawan, Philippines, have resulted in the discovery of two new ginger species, namely Boesenbergia eburnea Docot and Boesenbergia leonardocoi Funak. & Docot, which are described and illustrated here, including information on their distribution, habitat, phenology, ecology and conservation status. Additionally, a key to Boesenbergia species in the Philippines is provided.

While developing taxonomic studies about Connaraceae in Brazil, two new species of Rourea were discovered. Rourea barbata and R. prostrata are here described and illustrated. The new taxa belong to Rourea subgen. Rourea sect. Multifoliolatae and comparisons to morphologically similar species are provided, along with notes on their distribution, habitat, taxonomy and conservation status.

Abstract Three new taxa of subtribe Hyptidinae (Lamiaceae) from Amazonian Brazil are here described: two from Pará state Eriope macrostachya var. amazonica, and Hyptis cachimboensis, and Hyptis spathulata from Rondônia state. The diagnostic characters, which distinguish them from their closest relatives are described and discussed, their conservation status is given and a plate is provided for each of the new taxa. The Hyptidinae conspectus an earlier checklist of Lamiaceae from Amazonian Brazil is updated with various name changes since its publication, and with the addition of another two species of Hyptis not previously included. Also included, is a note on Hyptis sect. Eriosphaeria, to which the two new species described here, belong.

Sisyranthus species are cryptic in both their habit and small size of their flowers making them difficult to find in the wild. The genus was last revised in Flora Capensis (1908) and since then, two new species have been described. Currently it comprises 13 recognised species endemic to southern Africa. Many of these are range-restricted and poorly known. In this contribution the genus is further expanded by describing two novel species. Full descriptions, assessment of conservation status, distribution maps and line drawings of the new taxa are presented.

Recent findings based on molecular data support the occurrence in the Azores of several independently evolving lineages of the beetle genus Tarphius Erichson, 1845 (Coleoptera: Zopheridae Solier, 1834) and higher species richness masked by cryptic diversity, needing formal taxonomic description. All Tarphius from the Azores are revised using an integrative taxonomic approach, using evidence from morphology, morphometrics and molecular data to delimit species. Our results reveal that Azorean Tarphius comprise at least five phyletic lineages, two of which share a similar morphology, despite being divergent at the molecular level. A total of four new species are described grouped into two complexes: i) two new species in the “complex tornvalli” with the new taxa Tarphius relictus sp. nov. (Terceira) and Tarphius furtadoi sp. nov. (São Jorge, Faial and Pico) and; ii) two new species in the “complex azoricus-wollastoni-depressus” with the new taxa Tarphius gabrielae sp. nov. (Pico) and Tarphius floresensis sp. nov. (Flores). Descriptions, photographs of holotypes and morphological details, and remarks on diagnostic features comparing similar species are presented. Additional information on the distribution and conservation status of the 12 described species in the archipelago is also provided.

Two new species of Ixora are described from the provinces of Palawan and Samar, Philippines: I. alejandroi and I. reynaldoi. The two new species are compared mostly with other species of the genus from the Philippines and neighbouring Asian countries. Ixora alejandroi is characterized by its elongated cyme with congested secondary axes, reddish-brown corolla, stigmatic lobes shortly cleft in the middle, round at tip; while I. reynaldoi is easily recognised by its pseudanthium-type, 9–15 flowered inflorescences, long bracteoles (3.5–8 mm long), and keeled, foliaceous calyx lobes (8–10 mm long). The conservation status of each species is proposed, using IUCN Criteria.

Impatiens saulierea and I. josephia, two new species, are described from the Western Ghats, India. The former is collected from Kakkayam, Kozhikode and the latter from Idukki, Kerala. A detailed description of both taxa along with diagnostic characters between allied species, conservation status, pollen morphology and colour photographs are provided.

Eight new taxa of Eriophyidae mites associated with native trees in the Cupania genus—C. oblongifolia Mart. and C. impressinervia Acev (Sapindaceae)—from the Atlantic Forest in Brazil, are described and illustrated. They include two new genera and two new species of Nothopodinae, Colopodacini (Setibia domatiagena   gen. nov., sp. nov. and Aricolopodos alagoensis gen. nov., sp. nov.), one new genus and two new species of Cecidophyinae, Colomerini (Euryslobos keronidos gen. nov., sp. nov. and Gammaphytoptus cupanius sp. nov.), and one new species of Phyllocoptinae, Tegonotini (Shevtchenkella caboata sp. nov.).

Abstract We describe two new species of the freshwater-crab genus Demanietta  Bott, 1966 from Tanintharyi (Tenasserim) division, southern Myanmar (Burma), Demanietta liui  sp. nov. and Demanietta lenya  sp. nov.  Demanietta liui  sp. nov. is morphologically most similar to D. thagatensis  Rathbun, 1904 and D. khirikhan  Yeo, Naiyanetr & Ng, 1999; D. lenya  sp. nov. appears close to D. manii  Rathbun, 1904, D. merguensis  Bott, 1966, and D. nakhonsi  Yeo, Naiyanetr & Ng, 1999. The two new species are easily distinguished from their most similar congeners in the shape of the external orbital tooth, epibranchial tooth, and male first gonopod. Molecular analysis based on partial mitochondrial 16S rDNA also supports the systematic position of the new taxa.
