Dina sketi n. sp., a new erpobdellid leech (Hirudinida: Erpobdellidae) from Bosnia and Herzegovina.

open access: yesZootaxa, 2014
The concept of the genera within the family Erpobdellidae seems to be extremely artificial. Recent phylogenetic studies (Trontelj & Sket 2000, Siddall 2002) based on morphology and DNA sequence data showed that a revision of the family was necessary because the morphological characters used to distinguish known erpobdellid genera are not ...

A new leech species (Hirudinida: Erpobdellidae: Erpobdella) from a cave in the West Azerbaijan province of Iran.

open access: yesZootaxa, 2015
Erpobdella borisi n. sp. is a predatory leech inhabiting cave waters in Iran. Probably, it is either a troglobiont or troglophile. The leech has no eyes, and the complete mid-body somite is divided unequally into five annuli. Results of phylogenetic analysis based on morphological characters and COI gene sequence indicate the species to be closely ...

Chemosensory detection of prey by Nephelopsis obscura (Hirudinoidea: Erpobdellidae)

Hydrobiologia, 1982
The chemosensory detection of prey by the freshwater leech Nephelopsis obscura (Erpobdellidae) was investigated in the laboratory. Without direct tactile contact N. obscura of all three size classes tested were unable to detect and react to any of the prey types (Gammarus lacustris, Chironomus sp., Tubifex sp) or prey conditions (live, asphyxiated ...

Contribution to the knowledge of the genus Dina Blanchard, 1892 (Hirudinea: Erpobdellidae)

Hydrobiologia, 1995
This paper deals with the genus Dina of the Erpobdellidae. A comprehensive comparison of all known species of this genus is given. A lectotype for Dina absoloni Johansson, 1913, is selected. A new species, Dina latestriata n. sp. from Prespa Lake in Greece is described. Data concerning the evolution of Dina are given.

Reproductive success and growth of two species of Erpobdellidae: the effect of water temperature

Canadian Journal of Zoology, 1987
Cocoon production and hatchling growth of two species of Erpobdellidae (Nephelopsis obscura and Erpobdella punctata) were compared at different water temperatures (5–20 °C). Based on the mean number of cocoons produced per individual, mean numbers of eggs per cocoon, cocoon hatching success, and hatchling growth rates, E.

Intralacustrine speciation in the genus Dina (Hirudinea, Erpobdellidae) in Lake Ohrid (Yugoslavia)

Hydrobiologia, 1989
An extensive speciation within Erpobdellidae (resp. Dina) has been noted in the Ohridsko Ezero (Lake) (Yugoslav-Albanian border). All species are anatomically similar to D. lineata, but differ strikingly in their body shapes. To the already described D. ohridana Sket and D. lepinjaSket & Sapkarev, descriptions of D. krilata sp. n., D. svilesta sp.

The diet of Erpobdella octoculata (Hirudinea: Erpobdellidae) in two Danish lowland streams

Fundamental and Applied Limnology, 1997
The diet of leeches and the effect of prey size on feeding success were examined using gut analyses of Erpobdella octoculata from two Danish lowland streams. Five weight (size) classes of leeches were examined. For each insect prey found in the guts the width of the head capsule was measured.
