Chayamaritia vietnamensis, a new species from Son La Province, northern Vietnam, is described and illustrated. The phylogenetic study revealed that the new species is most closely related to C. banksiae and C. smitinandii. The morphological comparison suggests it as the third new species of Chayamaritia and distinguished from C. banksiae and C. smitinandii by a combination of morphological characters of leaf blades, bracts, calyx and corolla, especially its peltate leaf blades. This species is provisionally assessed as endangered (EN B1ab(iii), B2ab(iii)) using IUCN Categories and Criteria. Information on ecology, phenology and an identification key for the known Chayamaritia species are also provided.

A new species of betel nut palm, Areca jokowi, is described and illustrated here. This is the third species of Areca to have been described recently from New Guinea that is closely related to the widespread, economically important species A. catechu, the cultivated betel nut palm. A discussion of its morphological characters, distribution, ecology, habitat, uses and conservation status is provided, as well as a new identification key for western New Guinean Areca.

Abstract A new species of freshwater crab of the genus Teretamon Yeo & Ng, 2007, Teretamon husicum sp. nov., is described here from Husa Town, Longchuan County, Dehong Prefecture, Yunnan Province, China. Teretamon husicum sp. nov. can be distinguished from other species by a suite of morphological characters, including a bilobed frontal margin, smooth posterolateral regions, and a broadly rounded dorsal flap on the G1 terminal segment. An updated identification key for the species of the genus Teretamon is provided.

A new species of Sacada from northern Thailand is described: S. chaehomensissp. nov. Pellinen & Zahiri (Lepidoptera: Pyralidae, Pyralinae). Morphological characters and DNA barcode data are provided for the new species, with a morphological comparison to S. dzonguensis and S. umtasorensis, and a DNA-barcode comparison to S. ragonotalis and S. albioculalis, respectively. After this addition, the current number of valid species in the genus Sacada is 43.

Stenogiffardia bifurca sp. nov. is described from a series of specimens collected in the former Antananarivo, Fianarantsoa, and Toliara Provinces of Madagascar. This is the first record of the genus,Evans, 1977 (Hemiptera: Cicadellidae: Deltocephalinae) from Madagascar, which is now the third genus of the tribe Chiasmini known from the island. The distribution of,is analyzed and an identification key to species is given.,Evans, 1977 is removed from synonymy with,(Kirkaldy, 1906).

A peltate-leaved species of Begonia was recently collected from a limestone hill in central Guangxi, China. Based on a careful study of literature, herbarium material, and plants both in the wild and in cultivation reveals that it is a new species of Begonia sect. Coelocentrum, which we hereby describe as B. ufoides. In addition to a full taxonomic account, color plates and line drawings are provided to aid in identification. Begonia ufoides may be confused with B. umbraculifolia Y. Wan & B.N. Chang in southwestern Guangxi and B. phuthoensis H.Q. Nguyen in northern Vietnam, both of which are peltate-leaved calciphilous species in sect. Coelocentrum, but the new species  is clearly distinguishable in many morphological characters. A table comparing salient features of the three species is presented.

All previous records of Pachycheles rugimanus A. Milne-Edwards, 1880, from the Brazilian coast are reviewed and prove to represent a new species, P. coelhoi sp. nov. (from Amapá, northern Brazilian coast), and P. ackleianus A. Milne-Edwards, 1880, a species already known from Brazil (from Pará to Rio de Janeiro). The new species is described and illustrated, and compared to its most similar congeners: P. rugimanus and P. ackleianus from the western Atlantic, and P. velerae Haig, 1960, from the eastern Pacific (Galapagos Island and Cocos Island). Pachycheles coelhoi sp. nov. is distinguishable from the other three species by a suite of morphological characters, which include the ornamentation of the carapace and chelipeds, and the shape of the third thoracic sternite. All previous records of P. rugimanus from Brazil are considered invalid.

Plutomurus jordanai sp. nov. from Zeda Kvilishori Cave (Tskaltubo Municipality, Imereti region, Western Georgia) is described, illustrated and differentiated from other morphologically similar species‒‒P. kelasuricus Martynova, 1969 and P. eristoi Barjadze, Baquero, Soto-Adames, Giordano & Jordana, 2016. In addition, morphological characters omitted or erroneously provided in the original description of Plutomurus birsteini Djanashvili & Barjadze, 2011 are described and illustrated from the specimen sampled in the type locality‒‒Sakishore Cave (Racha region, Western Georgia). An identification key to the species of the genus Plutomurus reported from the Caucasus is presented. A list of the invertebrate communities for Zeda Kvilishori and Sakishore caves is provided.

A new species of the genus Eurostocepheus (Oribatida, Otocepheidae) is described from soil and litter of Tam Dao National Park in Northern Vietnam. Eurostocepheus (Eurostocepheus) wojciechniedbalai sp. nov. is morphologically most similar to E. (E.) mahunkai Mondal & Kundu, 1999 from India in the presence of four pairs of genital setae and medial prodorsal condyles, but differs by the quadrangular, anteromedially excavated lateral notogastral condyles, short interlamellar setae, short notogastral setae c, minute epimeral setae 1a, 2a, 3a, two pairs of epimeral setae on epimere IV, and by the transverse position of the anal setae. Revised generic and subgeneric diagnoses, an identification key to the known taxa, and data on the distribution and ecology of Eurostocepheus are presented.

The species of Centris of the hyptidis group are revised. The group, composed by C. hyptidis Ducke, C. hyptidoides Roig-Alsina, and C. thelyopsis n. sp., exhibits unique morphological characters within the genus, like foreand midtrochanters with a laminar expansion at the base, and elaiospathes strongly modified. An updated catalog, and floral and distributional records are provided for each species, as well as an identification key and a distribution map. The male of C. hyptidoides is described for the first time and a modern diagnosis for C. hyptidis is presented. A new species, C. thelyopsis n. sp., is described from Goiás State, in central Brazil. It can be easily distinguished from the two previously known species by its predominant orange pilosity, including that of the hind legs and metasoma.
