Some like it cold: the glossiphoniid parasites of the Sicilian endemic pond turtle Emys trinacris (Testudines, Emydidae), an example of ‘parasite ine…
2016
The freshwater turtles of the genus Emys and some leech species of the family Glossiphoniidae are the only Palaearctic representatives of primarily Nearctic taxa, which jointly colonized Eurasia and the Maghreb during the Miocene. The strict trophic relationships occurring between the glossiphoniid parasite leech Placobdella costata and its host, the emydid Emys orbicularis, make them a prime example of host–parasite cophylogenetic evolution. In the light of the discovery of the Sicilian cryptic endemic species Emys trinacris, which is the sister species to the widespread Palaearctic E. orbicularis, the possible cophylogenetic divergence of the turtle hosts and their leech parasites was inv…
Extensive sampling sheds light on species-level diversity in Palearctic Placobdella (Annelida: Clitellata: Glossiphoniiformes)
2022
The bloodfeeding leech genus Placobdella is dominated by North American diversity, with only a single nominal species known from Central America and one from the Palearctic region. This is likely due to considerable underestimation of Palearctic biodiversity, but investigations into potential hidden diversity are lacking. To shed light on this, the present study introduces new data for specimens initially identified as Placobdella costata from Ukraine (close to the type locality), Italy, Germany, Latvia, Montenegro, Bulgaria, Slovenia, Turkey, Azerbaijan, Tunisia, and Algeria, and uses both nuclear (Internal Transcribed Spacer [ITS] region) and mitochondrial (cytochrome c oxidase subunit I …
Registros de sanguijuelas de Costa Rica y clave para la identificación de las especies con redescripción de Cylicobdella costaricae Records of leeche…
2012
En contraste con los enormes esfuerzos realizados por caracterizar la fauna y flora de Costa Rica, con excepción de algunos registros aislados, muy poco se sabe sobre las sanguijuelas (Annelida: Clitellata) en este país. En este trabajo, presentamos la redescripción de una especie terrestre muy poco conocida: Cylicobdella costaricae, caracterizando su morfología externa e interna; esta última se mantenía completamente desconocida hasta la fecha. Adicionalmente, presentamos la primera lista de especies de sanguijuelas para Costa Rica con un total de 12 taxones registrados en las 7 provincias del país. Se incluye una breve descripción de su morfología, fotografías y localidades para cada taxó…
