Leeches of the genus Helobdella are small brooding annelids that inhabit lakes and streams on every continent, notably in South America. The type species, H. stagnalis L. 1758, occurs in Europe and North America. Here I provide novel observations on the occurrence, morphology, and parental care patterns of the related H. californica, a taxon described in 1988, based on specimens collected in Stow Lake, Golden Gate Park, San Francisco. In 2007, the original H. californica population no longer… Expand

Description of a new leech species from North America, Helobdella austinensis n. sp. (Hirudinea: Glossiphoniidae), with observations on its feeding behaviour
This work describes a variable taxon, that has been studied extensively, and was formerly labelled as Helobdella sp. Expand
A new species of Helobdella (Hirudinida: Glossiphoniidae) from Oregon, USA.
The new species has pale yellow/buff coloration with scattered chromatophore blotches throughout the dorsal surface, lateral extensions or papillae only on the a2 annulus, dorsal medial row of papillAE with small papilla on al and larger papillai on a2 and a3, and a small oval scute (rarely triangular). Expand
Two new Helobdella species (Annelida Hirudinida Glossiphoniidae) from the Intermountain region of the United States, formerly considered as Helobdella stagnalis Linnaeus, 1758
The dorsoventral histological sectioning of these 3 specimens showed the Utah and Nevada forms had compact salivary glands, hitherto noted only in the South American Helobdella and Haementaria species, suggesting the Intermountain area may be a prime region to study the evolution of members of the Helobda species complex. Expand
Helobdella blinni sp. n. (Hirudinida, Glossiphoniidae) a new species inhabiting Montezuma Well, Arizona, USA
These species are morphologically similar, however, comparing the COI mtDNA sequences of Helobdella blinni with sequences from nearby populations of Hel obdella modesta and other Helob della species from GenBank indicate that HelobDella blinki is genetically distinct from these other HelOBdella populations. Expand
Elasmopus yucalpeten sp. n. (Crustacea, Amphipoda, Maeridae) from the northern Yucatan coast, with a key for the genus in the Gulf of Mexico and biogeographic comments
A new amphipod species of the genus Elasmopus Costa, 1853 is described and illustrated based on material collected in a harbor on the northern Yucatan coast, southern Gulf of Mexico. ElasmopusExpand
The European medicinal leech Hirudo medicinalis L.: Morphology and occurrence of an endangered species
It is suggested that the loss of natural freshwater ecosystems, with flat, warm banks, and amphibians as preferred host organisms for the juveniles, are largely responsible for the decline of H. medicinalis in Northern Europe. Expand
Behavioral variation according to feeding organ diversification in glossiphoniid leeches (Phylum: Annelida)
The characteristics of leeches with specific ingestion behaviors, and a comparison of structural differences that serves as the first evidence of the proboscis diversification are provided. Expand
Leeches of the genus Helobdella as model organisms for Evo-Devo studies
The biology/taxonomy of these Evo-Devo systems of Helobdella leeches is depicted, and an updated scheme illustrating the unique germ line/soma-differentiation during early development is provided and speculated on the mechanisms of sympatric speciation in this group of aquatic annelids. Expand
Der altruistische Golden Gate‐Egel und das ITIS‐Projekt
Vor 25 Jahren wurde im Stow Lake des Stadtparks von San Francisco, Kalifornien, eine Egelart entdeckt und beschrieben, der “Golden Gate‐Leech” konnte inzwischen auch auf Grundlage of DNA‐Sequenz‐Analysen als neue Art identifiziert werden. Expand


Description of the Californian leech Helobdella robusta sp.nov., and comparison with Helobdella triserialis on the basis of morphology, embryology, and experimental breeding
Experimental studies indicate that H. robusta and H. triserialis have little or no proclivity for interbreeding, supporting their distinction as separate species. Expand
A new species of Haemopis (Annelida: Hirudinea): evolution of North American terrestrial leeches.
Morphological distinctions and geographic isolation support the designation of a new species of terrestrial leech, Haemopis ottorum, from the southern part of New Jersey, USA. Expand
Phylogeny and revision of the leech genus Helobdella (Glossiphoniidae) based on mitochondrial gene sequences and morphological data and a special consideration of the triserialis complex
The relationships, as well as identification of species, within Helobdella (Glossiphoniidae) were explored through phylogenetic analysis and through an overview of the historical systematics of theExpand
The occurrence of an Australian leech species (genus Helobdella) in German freshwater habitats as revealed by mitochondrial DNA sequences.
It is shown that this leech is genetically identical with the Australian species Helobdella papillornata and represents an introduced annelid that occupies the same ecological niche as the common European leech H. stagnalis. Expand
Phylogenetic evaluation of systematics and biogeography of the leech family Glossiphoniidae
There was strong support for monophyly of most accepted genera in the group, many of which are consistent with eyespot morphology, and the biogeographic implications of the phylogenetic hypothesis are evaluated for vertebrate hosts and Tertiary continental arrangements. Expand
The European land leech: biology and DNA-based taxonomy of a rare species that is threatened by climate warming
It is suggested that human-induced climate change without apparent habitat destruction can lead to the extinction of populations of cold-adapted species that have a low colonization ability. Expand
DNA-barcoding evidence for widespread introductions of a leech from the South AmericanHelobdella triserialis complex
Morphological examination and a molecular phylogenetic analysis of leeches from Australia, New Zealand, South Africa and Hawaii show that these specimens are members of a species in the SouthExpand
The Feeding Strategies of the Leech Erpobdella octoculata (L.): A Laboratory Study
The common leech E. octoculata is not only a predator, but also a fluid sucker and a scavenger, and the ecological implications of this finding are discussed. Expand
Arhynchobdellida (Annelida: Oligochaeta: Hirudinida): phylogenetic relationships and evolution.
The phylogenetic relationships of the order Arhynchobdellida were investigated using nuclear 18S and 28S rDNA, mitochondrial 12S r DNA, and cytochrome c oxidase subunit I sequence data, as well as 24 morphological characters, resulting in a single most-parsimonious tree. Expand
The evolution of parental care in freshwater leeches
It is concluded that the major selective pressure driving the evolution of parental care in leeches may have been predation on eggs and juvenile stages. Expand
