Two new (Oligochaeta, Moniligastridae) earthworms from Vietnam.

Two new earthworm species are described, namely and The former can be recognized by having male pores on spiniform penises in intersegment 10/11, an erect and sac-shaped spermathecal atrium, glandular prostate, the capsule coiled one round, the vas deferens strongly coiled but small, two large, round, genital markings on segments ix-x, and three gizzards in xiii-xv. The latter species is distinguished in having the male pores placed on highly elevated, backwardly directed, conical penises in 10/11, a slender spermathecal atrium, a glandular prostate, a somewhat folded capsule, the vas deferens strongly coiled as a bunch and equal size to the testis sacs, a pair of genital markings located closely anterior to the penises with 1-3 additional ones in xi-xii, and three or four gizzards in xiii-xvi. The DNA barcode fragment of the COI gene was extracted for each species, and the COI genetic distances and phylogenetic analysis also supported two new species.

A review and notes on the phylogenetic relationship of the centipede genus Otostigmus Porat, 1876 (Chilopoda: Scolopendromorpha: Scolopendridae) from Vietnam.

The genus Otostigmus Porat, 1876 is reviewed based on recent material collected from parts of Vietnam. A total of nine species are documented and imaged. The phylogeny of the genus Otostigmus is analyzed based on a 603-bp dataset of the cytochrome c oxidase subunit I (COI) gene.

Four new species of Amynthas earthworms in southeastern Vietnam (Annelida, Oligochaeta, Megascolecidae).

Four new earthworm species of the genus Amynthas Kinberg, 1867 are described from southeastern Vietnam, named A. longiprostaticus sp. nov.

Arbuscular mycorrhizal fungal inoculation and soil zinc fertilisation affect the productivity and the bioavailability of zinc and iron in durum wheat.

There is a growing recognition of the role of arbuscular mycorrhizal fungi (AMF) in food security, specifically the potential for AMF to enhance the yield and mineral nutrition-including phosphorus, zinc (Zn), and iron (Fe)-of food crops. However, the bioavailability of Zn and Fe for humans in the grain of cereal crops can be overestimated by failing to consider the abundance of phytic acid (PA). This is because PA can chelate the micronutrients, making them difficult to absorb.

Impact of an arbuscular mycorrhizal fungus on the growth and nutrition of fifteen crop and pasture plant species.

The formation of arbuscular mycorrhizas (AM) can result in positive, neutral or negative responses in the growth and mineral nutrition of host plants, particularly that of P, Zn and other micronutrients. This study examined the growth and nutritional responses of 15 agriculturally important plant species, including cereals, legumes and vegetables, with and without inoculation with the AM fungus (AMF) Rhizophagus irregularis. Furthermore, we explored whether the responses differed between different functional groups of plants such as monocots and dicots, C3 and C4 plants, and N-fixing and non-N-fixing plants.

First record of the millipede genus Nesorthomorpha Jeekel, 1980 in Vietnam with description of a new species (Diplopoda, Polydesmida, Paradoxosomatidae).

The genus Nesorthomorpha Jeekel, 1980 is recorded in Vietnam for the first time based on the discovery of the new species Nesorthomorpha montana n. sp. from the Highlands of Vietnam.

A comprehensive checklist of earthworm species and subspecies from Vietnam (Annelida: Clitellata: Oligochaeta: Almidae, Eudrilidae, Glossoscolecidae, Lumbricidae, Megascolecidae, Moniligastridae, Ocnerodrilidae, Octochaetidae).

The comprehensive checklist of earthworms in Vietnam is presented here listing 24 genera and 212 species arranged in eight families. For each species, bibliographic citations are given, including the original descriptions as well as notable citations affecting taxonomic status or distributional reports of a species. Distributions of each species are also provided.

Three new earthworm species of the genus Polypheretima Michaelsen, 1934 (Oligochaeta: Megascolecidae) from Vietnam.

The paper provides descriptions of three new species of the earthworm genus Polypheretima Michaelsen, 1934 from Dong Nai Province, South Vietnam. They are named Po. cattienensis sp.

Earthworms of the 'acaecate' Pheretima group in Vietnam (Oligochaeta: Megascolecidae), with description of a new species from the Mekong delta.

The 'acaecate' Pheretima group from Vietnam is revised, with description of a new species, Polypheretima mekongmontis sp. nov. A total of 18 species of three genera, Metapheretima Michaelsen, 1928, Planapheretima Michaelsen, 1934, and Polypheretima Michaelsen, 1934 has been recorded from Vietnam.

An annotated checklist of centipedes (Chilopoda) of Vietnam.

The centipede fauna of Vietnam is reviewed from the literature. A total of 71 species in 26 genera, 13 families in four orders, Scolopendromorpha, Geophilomorpha, Lithobiomorpha and Scutigeromorpha, has been recorded from Vietnam. Four genera, Tonkinodentus, Alluropus, Anopsobiella and Megalacrus, are monotypic; and twenty-two species and subspecies are known only from Vietnam.
