We describe a new species of small rhacophorid frog from north central Vietnam. Gracixalus quangi sp. nov. is morphologically and genetically most similar to G. gracilipes and G. supercornutus, but is distinguished from these species and all other rhacophorids in Vietnam and adjoining countries by a combination of their small size (males <25 mm); greenish, translucent skin; opaque yellow anterior surface of thighs, groin, and behind the insertion of the arm; black spots on the flanks and ventral surface of the thighs; triangularly pointed snout; and the presence of a tibiotarsal projection. Gracixalus quangi sp. nov. has a non-stereotypical, hyperextended vocal repertoire, with calls highly variable in structure, duration, amplitude and frequency (dominant frequency 4.1-4.7 kHz). Like G. gracilipes and G. supercornutus, G. quangi sp. nov. deposits egg clutches in clumps on leaves overhanging shallow forest pools or puddles. The new species is known from montane evergreen forest in Pu Hoat Proposed Nature Reserve in western Nghe An Province, between ∼600-1,300 m elevation. Preliminary molecular (mtDNA) data recovered two strongly supported clades within frogs currently considered to belong to genus Gracixalus, with the new species nested within a monophyletic clade consisting of G. gracilipes, G. supercornutus, and G. quyeti© 2011 Magnolia Press.

Of the subfamilies and genera known from Vietnam, the following taxa are treated in this second part of the series entitled "Generic Synopsis of the Formicidae of Vietnam": CERAPACHYINAE: Cerapachys, Simopone; AENICTINAE: Aenictus; DORYLINAE: Dorylus; LEPTANILLINAE: Leptanilla, Protanilla; AMBLYOPONINAE: Myopopone, Mystrium, Opamyrma, Prionopelta, Stigmatomma; PONERINAE: Anochetus, Brachyponera, Buniapone, Centromyrmex, Cryptopone, Diacamma, Ectomomyrmex, Euponera, Harpegnathos, Hypoponera, Leptogenys, Mesoponera, Odontomachus, Odontoponera, Parvaponera, Platythyrea, Ponera, Pseudoneoponera; ECTATOMMINAE: Gnamptogenys; PROCERATIINAE: Discothyrea, Probolomyrmex, Proceratium. For each of these subfamilies we provide keys to genera (when there is more than one genus) known from Vietnam. For each genus we provide a synopsis and a list of Vietnamese species. © 2014 Magnolia Press.

The Indo-Chinese species of the genus Myrmoteras are revised. We recognise one species in the subgenus Myagroteras and six species in the subgenus Myrmoteras from Vietnam, Myanmar and Thailand. Five new species are described based on the worker caste: M. concolor, M. jaitrongi, M. namphuong, M. opalinum, and M. tomimasai, all belonging to the sub-genus Myrmoteras.

Diversity of butterfly communities of a limestone tropical rain forest was carried out in four different habitat types (the natural forest, the secondary forest, the shrub and grass, and the inhabitant) in Xuan Son National Park, North Vietnam from 2010 to 2012. A total 139 species with 1,041 individuals of butterflies were recorded. The secondary forest has the greatest individual and species numbers; the shrub and grass habitat has more individual and species numbers than the natural forest; the inhabitant has the least individual and species numbers. The species composition and abundance of butterfly communities is similar between similar habitats (the natural forest and the secondary forest; and the shrub and grass and the inhabitant). There was a positive correlation between the size of species geographical distribution and the increasing forest habitat clearance levels. Although the natural forest has lower butterfly diversity, it is home of restrict geographical distribution range where plays an important role for conservation of rare butterfly species; the secondary forest plays an important role in conserving higher butterfly diversity; while the inhabitant shows the poorest butterfly diversity. © RUSSIAN ENTOMOLOGICAL JOURNAL, 2015.

Alpha taxonomy of Vietnamese ants was initiated by European and American authors in the early 20th century, and approximately 160 species and infraspecific taxa were described or recorded in this early period. From 1965 to 1966 an inventory project of insects in northern Vietnam was conducted by the Agriculture Ministry of Vietnam, and 36 ant species were recorded. The identity of those taxa, however, needs to be revised based on the modern taxonomy of ants. Since the end of the 1980's dozens of ant species have been newly recorded or described from Vietnam. Regional revisions dealing with Vietnamese species have also been published for several genera including Myrmica, Probolomyrmex, Pheidole, Acanthomyrmex and Anillomyrma. Furthermore, two new genera, Parvimyrma (Myrmicinae) and Opamyrma (Amblyo- poninae), were recently described from the country. However, there has been no comprehensive systematic treatment of the Vietnamese ants to date. In order to develop the taxonomy of ants in Vietnam, we have begun a program to: (1) explore local ant faunas; (2) give species codes to all species; (3) overview ant genera known from Vietnam; (4) describe unnamed taxa and review higher taxa known from Vietnam and adjacent areas. Ninety-two genera in twelve subfamilies have so far been recognized by us: DOLICHODERINAE: Chronoxenus, Dolichoderus, Iridomyrmex, Liometopum, Ochetellus, Philidris, Tapinoma, Technomyrmex; FORMICINAE: Acropyga, Anoplolepis, Camponotus, Cladomyrma, Echinopla, Gesomyrmex, Lasius, Lepisiota, Myrmoteras, Nylanderia, Oecophylla, Paratrechina, Paraparatrechina, Plagiolepis, Polyrhachis, Prenolepis, Pseudolasius, Undescribed genus "eg-2"; PSEUDOMYRMECINAE: Tetraponera; CERAPACHYINAE: Cerapachys, Simopone; AENICTINAE: Aenictus; DORYLINAE: Dorylus; LEPTANILLINAE: Leptanilla, Protanilla; AMBLYOPONINAE: Amblyopone, Myopopone, Mystrium, Opamyrma, Prionopelta; PONERINAE: Anochetus, Centromyrmex, Cryptopone, Diacamma, Harpegnathos, Hypoponera, Leptogenys, Odontomachus, Odontoponera, Pachycondyla, Platythyrea, Ponera; ECTATOMMINAE: Gnamptogenys; PROCERATIINAE: Discothyrea, Probolomyrmex, Proceratium; MYRMICINAE: Acanthomyrmex, Anillomyrma, Aphaenogaster, Calyptomyrmex, Cardiocondyla, Cataulacus, Crematogaster, Dacatria, Dilobocondyla, Gauromyrmex, Kartidris, Lasiomyrma, Liomyrmex, Lophomyrmex, Lordomyrma, Mayeriella, Meranoplus, Monomorium, Myrmecina, Myrmica, Myrmicaria, Oligomyrmex, Paratopula, Parvimyrma, Pheidole, Pheidologeton, Pristomyrmex, Proatta, Pyramica, Recurvidris, Rhopalomastix, Rhoptromyrmex, Solenopsis, Strumigenys, Temnothorax, Tetramorium, Vollenhovia, Vombisidris. As the first major contribution to the third goal of the program, here we provide: (1) a key to subfamilies, (2) a key to myrmicine genera, and (3) a synopsis of myrmicine and pseudomyrmecine genera known from Vietnam. A second paper will deal with the Aenictinae, Cerapachyinae, Dorylinae, Leptanillinae Amblyoponinae, Ponerinae, Ectatomminae and Proceratiinae, and a third with the Dolichoderinae and Formicinae.
