Separate Genus

The paper provides a key for identification and a checklist of mycoheterotrophic species of the genus Exacum, representing a well-defined group of achlorophyllous members of Gentianaceae regarded sometimes in the limits of a separate genus Cotylanthera. One novel species, E. zygomorpha, discovered in northern Vietnam, is described and illustrated as new for science. Among other features the discovered species strikingly differs from its congeners in having distinctly zygomorphic flowers.

We describe a new species of the Rhacophorus genus, which differs from all species known in Asia by the combination of characters. It strongly differs also from small and middle-sized species of Rhacophorus sensu lato: Rhacophorus calcaneus Smith, 1924, Leptomantis cyanopunctatus (Manthey et Steiof, 1998), Rhacophorus hoabinhensis Nguyen, Pham, Nguyen, Ninh et Ziegler, 2017, Rhacophorus hoanglienensis Orlov, Lathrop, Murphy et Ho, 2001, Zhangixalus jarujini (Matsui et Panha, 2006), Rhacophorus laoshan Mo, Jiang, Xie et Ohler, 2008, Rhacophorus pardalis Günther, 1858, Rhacophorus rhodopus Liu et Hu, 1960, Rhacophorus robertingeri Orlov, Poyarkov, Vassilieva, Ananjeva, Nguyen, Sang, and Geissler, 2012, Leptomantis robinsonii (Boulenger, 1903), Rhacophorus spelaeus Orlov, Gnophanxay, Phimminith, and Phomphoumy, 2010, Rhacophorus translineatus Wu, 1977, Rhacophorus turpes Smith, 1940, Rhacophorus vampyrus Rowley, Le, Thi, Stuart et Hoang, 2010, Rhacophorus viridimaculatus Ostroshabov, Orlov et Nguyen, 2013 by having brown color with two green dorsolateral stripes starting at the groin level and connecting through the distal part of eyelid with green triangle on the head, slender body and head, lower ratio HW/HL 0.86, lower HW/SVL 0.28 and lower ratio HL/SVL 0.32.

A New Species

Peliosanthes longiracemosa, a new species from limestone areas of northern Vietnam, is described and illustrated. It is most similar to P. macrostegia in having a distally incurved staminal corona and a distinct pyramidal style, but clearly distinguishable chiefly by the broader leaf blades with more longitudinal veins and closer transverse veinlets, relatively longer, more slender raceme, more numerous widely expanded flowers with recurved perianth segments, and more incrassate, depressed globose staminal corona. Information on the habitat and phenology as well as notes on the taxonomic relationships with other congeners is also provided.

A New Species

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.

Sterile Leaf

A new fern species, Pteris langsonensis belonging to the P. cadieri complex (Pteridaceae), is described and illustrated from Lang Son Province, northern Vietnam. P. langsonensis is most similar to P. plumbea, but the former has typical dimorphic leaves and fertile pinnae much contracted and with a width of no more than half of sterile pinnae, while the latter has slightly dimorphic leaves. The new species is also similar to P. cretica, but the former has smaller habit and slightly toothed sterile leaf margins.

The present study is based on oribatid mite material (Acari, Oribatida) collected from Tam Dao National Park (Northern Vietnam) in 1988. A list of identified taxa, including 119 species from 80 genera and 47 families, is presented; of these, 13 species (Epilohmannoides rabori, Camisia spinifer, Sadocepheus undulatus, Eremobelba flexuosa, Hammerella excisa, Suctobelbella inenodabilis, Dolicheremaeus auritus, Eupelops acromios, Protoribates genitalis, Allogalumna machadoi, Carinogalumna philippinensis, Pergalumna magnipora capillaris, Galumnella nipponica) and five genera (Epilohmannoides, Camisia, Sadocepheus, Brassiella, Carinogalumna) are recorded in the Vietnamese fauna for the first time, and two species (Tokunocepheus mizusawai, Flagellozetes (Cosmogalumna) ornatus), one genus (Tokunocepheus) and one family (Tokunocepheidae) are recorded in the Oriental region for the first time. Two new species are described: Ramusella paraarcuata sp. nov. differs from Ramusella arcuata Mahunka & Mahunka-Papp, 2012 by the larger body size, lamellar setae similar in length and thickness to interlamellar setae, the presence of two or three branches on bothridial setae, and the absence of notogastral setae c. Neoribates paragracilis sp. nov. differs from Neoribates gracilis Travé, 1972 by the larger body size, and the presence of long apex (not shorter than head) on bothridial setae.

A New Species

The genus Aspidistra Ker Gawler (1822: 628) is represented in tropical and subtropical SE Asia by more than 160 species. It has the highest diversity in southern China and northern Vietnam (Tillich 2005, 2014, Tillich & Averyanov 2012, Vislobokov et al. 2013). In Vietnam, more than 50 species are known: many species have been discovered from the limestone regions in North Vietnam, while about 21 species are found from sandstone forests in Central and South Vietnam (Gagnepain 1934, Bogner & Arnautov 2004, Bräuchler & Ngoc 2005, Averyanov & Tillich 2012, 2013, 2016a, 2016b, Averyanov et al. 2016, Tillich 2005, 2014, Tillich & Averyanov 2008, Tillich et al. 2007, Leong-Škorničková et al. 2014, Vislobokov 2015, Vislobokov et al. 2013, 2014b, 2014c, 2016a, 2016b, Lý & Tillich 2016). During extensive floristic surveys in Central Vietnam in 2016, several interesting specimens of Aspidistra were collected by the first author. The critical examination of these specimens and study of literature for Aspidistra in Vietnam and neighbouring countries allowed to evidence several new taxa, two of which have been recently described: A. averyanovii Lý & Tillich (2016: 54) and A. parviflora Lý & Tillich (2016: 56). In the present paper, we describe a further new species from Cà Đam mountains, Quảng Ngãi Province, namely Aspidistra cadamensis.

A New Species

In this paper, we report a new asexual-morph taxon belonging to the family Cordycipitaceae (Hypocreales), which is associated with a sexual morph of an ophioceras-like taxon on submerged wood collected from Baoshan, Yunnan, China. Morphologically, this new taxon is similar to known asexual morphs of Lecanicillium and characterized by conidiophores arising from hyaline hyphae, with gregarious, ellipsoid to ovoid, aseptate conidia. Phylogenetic analyses of a combined LSU, SSU, tef1-α and ITS sequence dataset positions our taxon in Cordycipitaceae and close to Lecanicillium sp. (CBS 639.85) and L. primulinum. Lecanicillium subprimulinum is introduced as a new species with support from molecular data.

The present study is based on oribatid mite material (Acari, Oribatida) collected from the city of Hanoi in Northern Vietnam. A list of identified taxa, including 68 species from 49 genera and 32 families, is presented; of these, ten species (Trhypochthonius japonicus, Nothrus oblongus, Hermanniella aliverdievae, Arthrodamaeus decemsetiger, Arcoppia fenestralis orientalis, Ramusella puertomonttensis, Allosuctobelba grandis, Scheloribates elegans, Neoribates gracilis, Pergalumna corniculata) and one genus (Trhypochthonius) are recorded in the Vietnamese fauna for the first time; seven species (Xenillus selgae, Arcoppia curtipila, Cycloppia granulata, Hammerella gracilis, Allosuctobelba tricuspidata, Ceratozetoides maximus, Protoribates hakonensis) and one genus (Ceratozetoides) are recorded in the Oriental region for the first time. Two new species belonging to the genera Allosuctobelba and Oribatella are described: Allosuctobelba alexanderkhaustovi sp. nov. differs from Allosuctobelba tricuspidata tricuspidata Aoki, 1984 in the rostrum having three to four lateral teeth and very long notogastral setae positioned in two parallel rows; Oribatella pavelklimovi sp. nov. differs from Oribatella kunsti Bernini, 1972 by the granulate body surface, setiform  aggenital setae and the dorsolateral position of notogastral setae lm and lp.
