DNA barcoding of the Thai species of terrestrial earthworms in the genera Amynthas and Metaphire (Haplotaxida: Megascolecidae)

European Journal of Soil Biology, 2017
Terrestrial earthworms in the genera Amynthas Kinberg, 1867 and Metaphire Sims and Easton, 1972 are the most dominant and abundant earthworm species in Southeast Asia. However, the classification into species level of both genera is often confusing because of morphological similarities between species, a high level of morphological variability within ...

The position of the Haplotaxidae in the evolution of oligochaete annelids

Hydrobiologia, 1984
The Haplotaxidae have all the characteristics to support the hypothesis that they are the living descendents of the stem forms from which all of the Oligochaeta Clitellata (Orders Lumbriculida, Haplotaxida, Lumbricida, Tubificida) can be derived. The Aphanoneura are distinct from the Clitellata and are raised to a separate Class.

The ultrastructure of the spermatozoon of Haplotaxis ornamentus (Annelida, Oligochaeta, Haplotaxidae) and its phylogenetic significance

Zoomorphology, 1982
The spermatozoon of Haplotaxis ornamentus has characteristics common to all oligochaete sperm: filiform; primary acrosome vesicle carried on an acrosome tube and containing an axial rod (perforatorium) in an invagination (subvesicular space or secondary acrosomal invagination); an elongate, highly condensed cylindrical nucleus followed by a cylindrical

Soil macroinvertebrate communities: A world‐wide assessment

open access: yesGlobal Ecology and Biogeography, 2022
Abstract Aim Macroinvertebrates comprise a highly diverse set of taxa with great potential as indicators of soil quality. Communities were sampled at 3,694 sites distributed world‐wide. We aimed to analyse the patterns of abundance, composition and network characteristics and their relationships to latitude, mean annual temperature and rainfall, land ...

A taxonomic revision of the family Haplotaxidae (Oligochaeta)

Journal of Zoology, 1966
The family Haplotaxidae is re‐defined and the genera Pelodrilus, Heterochaetella and Adenodrilus are merged in the single genus Haplotaxis. Haplotaxis dubius and Haplotaxis ascaridoides are recognized as subspecies of Haplotaxis gordioides, and H. forbesi is regarded as synonymous with H. gordioides following a re‐examination of the type material.
