Distribution and descriptive characteristics of the two giant pill millipedes of the genus Sphaerobelum Verhoeff, 1924 (Diplopoda, Sphaerotheriida, Zephroniidae) in Vietnam

Two giant pill millipedes, Sphaerobelum clavigerum Verhoeff, 1924 and Sphaerobelum hirsutum Verhoeff, 1924, were described from unindicated localities in northern Vietnam. The paper presents the recorded localities, descriptions and colour illustrations of those giant pill millipedes. S. clavigerum Verhoeff, 1924 is recorded from Cuc Phuong National Park (Ninh Binh Province), and distinguished from its congeners by body being shiny, glabrous, anterior telopods 3-segmented, process of 2nd podonomere of posterior telopods slender, not apically strongly swollen. In contrast, S. hirsutum Verhoeff, 1924 is found in Tam Dao National Park and Me Linh Biodiversity Station (both in Vinh Phuc Province), and recognized by body being densely hairy, process of 2nd podonomere of posterior telopods apically strongly swollen, spherical, wider than basis of 3rd podomere. In addition, a key to genera of giant pill millipedes is also provided for the Vietnam fauna.

A new species of Heliogomphus from Vietnam (Odonata: Gomphidae)

Heliogomphus bidentatus sp. nov. (holotype male: Tam Dao National Park, Vinh Phuc Prov., northern Vietnam) is described from north and central Vietnam. This new species is similar to H. scorpio (Ris, 1912), but can be separated by the coloration of the thorax and details of the male caudal appendages. Information on its biology and ecology is provided.

Oribatid mites (Acari, Oribatida) from Tam Dao National Park (Northern Vietnam), with description of two new species

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.

Tamdamaeus staryi gen. nov., sp. nov. (Acari, Oribatida, Damaeidae) from Vietnam, with remarks on certain unusual diagnostic features

A new oribatid mite genus, Tamdamaeus gen. nov., with its type species, Tamdamaeus staryi sp. nov., belonging to the family Damaeidae, is proposed and described from leaf litter and soil from Tam Dao National Park (Northern Vietnam). It is close to the genus Damaeus C.L. Koch, 1835, but differs from the latter by the absence of spinae adnatae on the notogaster and by specific leg setation with 6 setae on femora II and IV. The position of the new taxa within related genera and species is discussed.

New Neoribates (Acari, Oribatida, Parakalummidae) from Vietnam

Three new species of oribatid mites of the genus Neoribates (Oribatida, Parakalummidae) are described based on adult specimens from the Tam Dao National Park of Northern Vietnam. Neoribates pseudojacoti sp. nov. differs from Neoribates jacoti Balogh & Mahunka, 1967 by the presence of clavate bothridial setae, median ridge of rostrum and adanal setae of medium size, and the localization of lamellar setae on prodorsum laterally to lamellar ends. Neoribates striatissimus sp. nov. differs from Neoribates similis Fujikawa, 2007 by the striate body surface, minute rostral setae and five pairs of genital setae. Neoribates protrusus sp. nov. differs from Neoribates rotundus Aoki, 1982 by the presence of barbed bothridial setae, rudimentary parts of translamellar line and very long interlamellar setae with attenuate tips.

New Protoribates (Acari, Oribatida, Haplozetidae) from Vietnam

Three new species of oribatid mites of the genus Protoribates (Oribatida, Haplozetidae) are described based on adult specimens from the Tam Dao National Park of Northern Vietnam. Protoribates chistyakovi sp. nov. differs from P. sangumburiensis (Choi, 1996) by being larger, the localization of lamellar setae, and morphology of rostrum and interlamellar setae. Protoribates shaldybinae sp. nov. differs from P. dentatus (Berlese, 1883) by its distinctly foveolate body surface, morphology of pedotecta II and leg tarsi I and II, and much longer adanal setae ad2. Protoribates shvanderovi sp. nov. differs from P. gracilis (Aoki, 1982) by its larger body size, localization of lamellar setae, and the relative lengths of lamellar, interlamellar and bothridial setae, and longer dorsophragmata. An identification key to the Vietnamese species of the genus Protoribates is given.

Contribution to the knowledge of the oribatid mite genus Eurostocepheus (Acari, Oribatida, Otocepheidae)

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.

New data on oribatid mites of Galumna (Galumna) (Acari, Oribatida, Galumnidae) from Northern Vietnam, with a key to species of this subgenus in the Oriental region

A new species of Galumna (Galumna) (Oribatida, Galumnidae) are described from a sample of grass rhizosphere, from a meadow of the Tam Dao National Park, Northern Vietnam. Galumna (Galumna) dkrivolutskyi sp. nov. differs from G. pseudotriquetra Ermilov, 2015(b) by the larger body size, bothridial heads slightly developed unilaterally and by the absence of sejugal suture medially. A supplementary description of G. discifera Balogh, 1960 is present based on Vietnamese specimens. Morphological additions to description of the Vietnamese species, G. acutirostrum Ermilov & Anichkin, 2010, are given. An identification key to known species of Galumna (Galumna) from the Oriental region is provided.
