“…One species (Pontobdella muricata, Linnaeus 1785) from a total of three species of ma-rine leech was found on the dorsal surface of Thornback Ray, Raja clavata which was caught in 2013 in Antalaya, Turkey (Bulguroglu et al, 2015). Moreover, a total of 37 species belonging to six families and 19 genera are found in the North African countries (Ahmed et al, 2015a), including 13 leech species belong to two orders, two suborders, four families, and 11 genera found in Tunisia (Ahmed et al, 2015b). Recently, a new oioxenous marine leech species was isolated from external surfaces (mouth and cloaca) of the banded guitarfish Zapteryx exasperate caught in the Gulf of California and Eastern Pacific Ocean off the coast of San Diego, California.…”

The aims of this study were to identify and to determine life cycle of marine leech isolated from cultured hybrid grouper “cantik” (Epinephelus fuscoguttatus fx E. polyphekadion m) in the northern Bali waters of Indonesia under laboratory conditions. Observation of the life cycle of the marine leech was done using petri-dishes (9 cm in diameter) arranged into two groups. In group-1, a petri-dish was filled with sterile seawater (with water exchange of 50%-60% every two days) and in group-2, a petri-dish was filled with continuous running water. DNA sequence was aligned with the sequences from GenBank by BLAST program. Results of similarity index with GenBank sequence exhibited that the nucleic acid of the marine leech isolated from the hybrid grouper “cantik” showed high similarity (99%) with Zeylanicobdella arugamensis. One adult leech could produce 1-63 eggs. The eggs were developed into morula, blastula, and gastrula within five days. The early phase of the embryo with daily water exchange treatment started on day-6 and hatched into larvae on day-10. The eggs incubated with continuous running water had hatched faster (eight days). However, not all eggs hatched at the same time. Some of the eggs hatched 1-3 days after the first one. Hatching rate of eggs varied from 2.70% to 100%. The newly hatched Z. arugamensis larva has transparent color and length of 1.0-1.5 mm. On day-6, Z. arugamensis larvae were already seen attaching to the body of the fish. The size of the Z. arugamensis larvae ranged between 3-11 mm on day-9. In that stage, they were able to produce eggs. Therefore, we argue that Z. arugamensis only requires 17 to 22 days to develop into the adult stage.

“…In Tunisia (Fig. 5D), this species was recorded in the North East of the country in the governorate of Nabeul in two stations: Lebna drainage basin (36.44326N, 010.5525,5E) by Ben Ahmed et al (2008a) Diagnosis: The maximum length is 3 cm. The body has obvious paired pulsatile vesicles.…”

“…5C), this species was collected by Henri Gadeau de Kerville in Jendouba governorate: the valleys of el Omor (Tabarka) and El Lebga (Aïn Drahim), being identified by Blanchard (1908) as Placobdella catenigera. Ben Ahmed et al (2008a) have recorded it in Nabeul governorate (Lebna drainage basin). In this paper, we add its presence in a new locality of this later governorate: Port Prince drainage basin (36.51162 N, 10.39404E); in a marsh in Jendouba governorate (36.30N, 8.47E) and in a source in El Kef governorate (36.1056N, 8.4253E).…”

“…Available information on the distribution, taxonomy, and ecology of Tunisian leeches has been scattered throughout various historical (Blanchard 1891, 1908, Megnin 1891, Seurat 1922 as well as recent papers (Ben Ahmed et al 2008a, 2008b, 2008c, Ben Ahmed & Tekaya 2009, Ben Ahmed et al, 2013, Nesemann & Neubert 1994. None of these papers have focused on the country's fauna as a whole.…”

In this study 13 leech species from Tunisia are listed. They belong to 2 orders, 2 suborders, 4 families and 11 genera. The paper includes also data about hosts and habitats, distribution in the world and in Tunisia. Faunistic informations on leeches were found in literature and in the results of recent surveys conducted by the authors in the North East and the South of the country. The objectives of this study were to summarize historical and recent taxonomic data, and to propose an identification key for species signalized. This checklist is to be completed, taking into account the hydrobiological network of the country especially the North West region, which may reveal more species in the future

Placobdella nabeulensis sp. nov. (Hirudinea: Glossiphoniidae), a new glossiphoniiform leech from Palearctic North Africa

Herein, we describe a new species of turtle blood-feeding leech, Placobdella nabeulensis sp. nov. from Palearctic North Africa (Tunisia and Algeria). The new species is described based on detailed morphological analyses using light and scanning electron microscopes. Apart from the detailed morphology of the atrium, morphological features alone do not su ciently separate the species from congeners due to the absence of distinct diagnostic characters. Therefore, we turned to molecular data to better distinguish this new species from other members of the genus and establish a basis for its genetic separation. Four DNA fragments were successfully ampli ed, including mitochondrial COI and 12s rDNA, as well as nuclear 28S rDNA and histone H3. We then provided the molecular descriptor of the taxon, based on redundant diagnostic nucleotide combinations in DNA sequence alignment within the Folmer region. Results of the phylogenetic analysis and species delimitation methods (ABGD, ASAP, and bPTP) based on the COI locus support the species rank of the Tunisian-Algerian Placobdella. The new species is most closely related to the European species Placobdella costata (Fr. Müller, 1846) and the present study indicates that Placobdella nabeulensis sp. nov. has likely been confused with the European counterpart in several previous studies.
