Article
Full-text available
The diversity of Indochinese prawns in genus Macrobrachium is enormous due to the habitat diversification and broad tributary networks of two river basins: the Chao Phraya and the Mekong. Despite long-standing interest in SE-Asian decapod diversity, the subregional Macrobrachium fauna is still not yet comprehensively clarified in terms of taxonomic...
Article
Full-text available
Specific status and species boundaries of several freshwater prawns in the Macrobrachium pilimanus species group remain ambiguous, despite the taxonomic re-description of type materials and additional specimens collected to expand the boundaries of some species. In this study, the "pilimanus" species group of Macrobrachium sensu Johnson (1958) was...

After the publication of the comprehensive monograph on Burmese earthworms by Gordon E. Gates in 1972, there has only been one recent publication by Csuzdi et al. (2015), which reported seven species records belonging to the families Moniligastridae, Benhamiidae, Octochaetidae and Megascolecidae, but did not include any species in the family Almida...
Article
Full-text available
Biological and behavioral responses of the tropical earthworm Perionyx excavatus towards different concentrations of abamectin were evaluated. Abamectin significantly reduced the biomass and reproduction (cocoon production) of P. excavatus as well as inducing histopathological alterations in the cuticle. Biomass loss was recorded in P. excavatus ex...

The luminous earthworm Pontodrilus litoralis (Grube, 1855) occurs in a very wide range of subtropical and tropical coastal areas. Morphometrics on size variation (number of segments, body length and diameter) and genetic analysis using the mitochondrial cytochrome c oxidase subunit 1 (COI) gene sequence were conducted on 14 populations of P. litora...
Article
Semi-aquatic freshwater earthworms in the genus Glyphidrilus from Southeast Asia are characterized by both an extreme morphological crypsis among divergent phylogenetic lineages and a high morphological variability within the same phylogenetic lineages. The present study provides a new taxonomic framework for this problematic genus in SE Asia by in...
Article
Full-text available
The land area of Laos is composed of a large variety of undisturbed habitats, such as high mountainous areas, huge limestone karsts and the lower Mekong Basin. Therefore, Laos is expected to have a high species diversity, especially for the land snails. However, with respect to research on malacology, Laos is probably the least well-researched area...
Article
A new species of the megascolecid earthworm genus Pontodrilus Perrier, 1874, Pontodrilus longissimus sp. n., is described from seashores of Thailand and Peninsular Malaysia. The new species differs from congeners, especially the cosmopolitan P. litoralis (Grube, 1855) in the size of the body, number of segments and the shape of the spermathecae. P....
Article
Metaphire peguana (Megascolecidae) is a terrestrial earthworm that was found to be widely distributed throughout the whole of Penang state during our field collecting. The differences in the average length and diameter of M. peguana between the island and mainland Penang population were correlated with their behavior and the environmental parameter...
Article

Seven new species of semi-aquatic freshwater earthworms belonging to the genus Glyphidrilus Horst, 1889 are described from Thailand and Laos, Glyphidrilus nanensis Chanabun & Panha sp. n., G. satunensis Chanabun & Panha sp. n., G. chiangraiensis Chanabun & Panha sp. n., G. namphao Chanabun & Panha sp. n., G. sekongensis Chanabun & Panha sp. n., G....
Article
Combining morphological and molecular data is a powerful approach to support the discovery of new species. Here, two new species of the semi-aquatic earthworm genus Glyphidrilus , G. jamiesoni sp. n. and G. kralanhensis sp. n., are described from the Mekong Basin in Cambodia. They are morphologically distinguished by the respective locations of win...
Article
Full-text available
Earthworm specimens collected from various parts of Thailand were found to contain seven new species of the genus Metaphire Sims & Easton, 1972. These are M. songkhlaensis sp. n. in the octothecal pulauensis species group, M. trangensis sp. n. in the octothecal ignobilis species group, M. khaoluangensis sp. n. and M. khaochamao sp. n. in the sexthe...
Article
Full-text available
The semi-aquatic freshwater earthworm genus Glyphidrilus Horst, 1889 from Thailand was investigated based on extensive recent collecting. The species in this genus were characterized by their external and internal morphological characters of the location of wings, genital openings, genital organ structures and their locations, as well as the dimens...
Article
Full-text available
Three new species of semi-aquatic freshwater earthworms of the genus Glyphidrilus Horst, 1889 are described from Malaysia. Glyphidrilus bisegmentus sp. n. was collected from Air Banun Pandig, Perak, Glyphidrilus kotatinggi sp. n. from Kota Tinggi waterfall, Johor, and Glyphidrilus peninsularis sp. n. from Sungei Bantang, Johor. For comparison, type...

Full-text available
We report the discovery of a new semi-aquatic earthworm of the genus Glyphidrilus Horst, 1889 from the Mekong River, Ubon Ratchathani Province, Thailand. The description of the new species includes morphological characters of the adults, cocoons and newly-hatched juveniles. Moreover some ecological observations of the new species including the rela...

Four new species of terrestrial earthworms from the zebrus-group in the genus Amynthas Kinberg, 1867, are described from Nan province, north Thailand: Amynthas phatubensissp. n., from Tham Pha Tub Arboretum, Amynthas tontongsp. n., from Tontong Waterfall, Amynthas borealissp. n., from Chaloemprakiat district, and Amynthas srinansp. n., from Srinan...

A project on an inventory of earthworm fauna in Nan province, north Thailand and nearby areas has been carried out since 2009, with a focus on the two common genera Amynthas Kinberg, 1867 and Metaphire Sims and Easton, 1972. In this paper we report on the occurrence of species of the genus Metaphire. The cosmopolitan species Metaphire peguana (Rosa...
