TheBalkan crested newtorBuresch's crested newt(Triturus ivanbureschi) is anewtspecies of the crested newtspecies complexin genusTriturus, found in Southeastern Europe andAnatolia.[2]
It was originally described as asubspeciesof thesouthern crested newt, "Triturus karelinii arntzeni", in 1999,[3]and later considered a full species when genetic data showed it to be distinct.[4]After it was suggested thetype specimenof "T. arntzeni" belonged in fact to theMacedonian crested newt(T. macedonicus), the species was redescribed, with a new type specimen, asT. ivanbureschiin 2013. Thespecies epithetwas chosen in honour of Bulgarian herpetologistIvan Buresh.[2]
Its distribution ranges from the Southeastern Balkan peninsula (WesternMacedonia, NorthwesternGreece,Bulgaria,Eastern Thrace) to Western Anatolia. An isolated population, surrounded by other crested newt species, occurs inSerbia.[2]Genetic data showed that Northern Anatolian populations east of theBosphorusandBursaform a separate, but morphologically indistinguishablesibling species, which was described asAnatolian crested newt(T. anatolicus) in 2016.[5]
The Balkan crested newthybridiseswith the Anatolian crested newt at its eastern range end.[5]At the western and northern borders, it hybridises with the Macedonian crested newt, theDanube crested newt(T. dobrogicus), and thenorthern crested newt(T. cristatus).[6]The type specimen of "T. arntzeni" is in fact a hybrid between the Balkan and the Macedonian crested newt, so that this name is a synonym for both species.[7]
Ο Βαλκανικός χτενοτρίτωνας, Triturus ivanbureschi Arntzen & Wielstra, 2013 ή χτενοτρίτωνας του Buresh, είναι ένα είδος τρίτωνα που ανήκει στο σύμπλεγμα ειδών χτενοτριτώνων του γένους Triturus. Εντοπίζεται στη Ν.Α. Ευρώπη και την Ανατολία[1]. Πρόκειται για μεγάλου μεγέθους τρίτωνα που μπορεί να φτάσει μέχρι και τα 18cm ολικό μήκος[2].
Αρχικά, περιγράφηκε ως είδος υποείδος του νότιου χτενοτρίτωνα Triturus karelinii arntzeni το 1999[3]. Αργότερα ανάχθηκε σε επίπεδο είδους, καθώς γενετικές μελέτες έδειξαν ότι αποτελεί ένα διακριτικό εξελικτικό κλάδο[4]. Αργότερα, αποδείχθηκε ότι ο ολότυπος του "T. arntzeni" ουσιαστικά ανήκε στο είδος T. macedonicus, έτσι το είδος περιγράφηκε εκ νέου με νέο ολότυπο ως T. ivanbureschi το 2013. Η ονομασία δόθηκε ως φόρος τιμής στον Βούλγαρο ερπετολόγο Ivan Buresh[1].
Η κατανομή του είδους περιλαμβάνει τη Ν.Α. Βαλκανική χερσόνησο (Δυτική Βόρεια Μακεδονία., Β.Δ. Ελλάδα, Βουλγαρία, Ανατολική Θράκη) και μέρος της Δ. Ανατολία. Ένας απομονωμένος πληθυσμός που περιβάλλεται από άλλα είδη χτενοτριτώνων εντοπίζεται στη Σερβία[1].
Προτιμά κυρίως ορεινά δάση. Κυρίως νυκτόβιο είδος. Ζευγαρώνει στο νερό κατά την περίοδο της άνοιξης σε μικρές λίμνες, στάσιμα ή ελαφρώς ρέοντα νερά. Η μεταμόρφωση των προνυμφών συνήθως διαρκεί 3 με 4 μήνες. Η ενηλικίωση αρχίζει στο 3ο με 5ο έτος της ζωής του, ενώ η διάρκεια ζωής του υπολογίζεται στα 8-15 χρόνια με τα θηλυκά να ζουν περισσότερο από τα αρσενικά. Πέφτει σε χειμερία νάρκη τον Σεπτέμβριο ή Οκτώβριο ανάλογα με την θερμοκρασία[2].

The Balkan crested newt or Buresch's crested newt (Triturus ivanbureschi) is a newt species of the crested newt species complex in genus Triturus, found in Southeastern Europe and Anatolia.[2]
It was originally described as a subspecies of the southern crested newt, "Triturus karelinii arntzeni", in 1999,[3] and later considered a full species when genetic data showed it to be distinct.[4] After it was suggested the type specimen of "T. arntzeni" belonged in fact to the Macedonian crested newt (T. macedonicus), the species was redescribed, with a new type specimen, as T. ivanbureschi in 2013. The species epithet was chosen in honour of Bulgarian herpetologist Ivan Buresh.[2]
Its distribution ranges from the Southeastern Balkan peninsula (Western North Macedonia, Northwestern Greece, Bulgaria, Eastern Thrace) to Western Anatolia. An isolated population, surrounded by other crested newt species, occurs in Serbia.[2] Genetic data showed that Northern Anatolian populations east of the Bosphorus and Bursa form a separate, but morphologically indistinguishable sibling species, which was described as Anatolian crested newt (T. anatolicus) in 2016.[5]
The Balkan crested newt hybridises with the Anatolian crested newt at its eastern range end.[5] At the western and northern borders, it hybridises with the Macedonian crested newt, the Danube crested newt (T. dobrogicus), and the northern crested newt (T. cristatus).[6] The type specimen of "T. arntzeni" is in fact a hybrid between the Balkan and the Macedonian crested newt, so that this name is a synonym for both species.[7]

Triturus ivanbureschi est une espèce d'urodèles de la famille des Salamandridae[1].
Cette espèce se trouve en Serbie, en Macédoine, en Bulgarie, dans le nord de la Grèce et dans l'ouest de la Turquie[1].
Cette espèce est nommée en l'honneur de Ivan Buresch (1885-1980)[2].

Triturus ivanbureschi Arntzen & Wielstra in Wielstra, Litvinchuk, Naumov, Tzankov, & Arntzen, 2013 è un anfibio caudato appartenente alla famiglia dei Salamandridi[1].
Tritone crestato di grandi dimensioni e struttura robusta, con dorso scuro, di colori variabili dal marrone al grigio, e macchie tondeggianti nere, spesso leggermente verdognole. Fianchi quasi privi di puntini bianchi. Ventre e gola sono di colore arancione brillante, con macchie nere ben definite. Nel periodo riproduttivo i maschi presentano una cresta dorsale alta, nettamente seghettata, e cresta caudale liscia. A ciascun lato della coda si trova una banda longitudinale bianco-argentea. Ha una lunghezza totale di 14-18 cm[2].
Il tritone crestato Triturus ivanbureschi è un ottimo esempio dell'intricata tassonomia di questo gruppo: in un primo momento, infatti, fu considerato una variante e poi una sottospecie del tritone crestato di Karelin (Triturus karelinii), diffuso nel nord-est della Turchia e nel Caucaso. Successivamente fu classificato come specie a sé stante con il nome di Triturus arntzeni e infine nuovamente descritto nel 2013 con un altro nome, dal momento che il nome «arntzeni» si riallacciava a una forma ibrida tra T. macedonicus e T. ivanbureschi, risultando quindi un sinonimo un valido[2].
Triturus ivanbureschi occupa la parte sud-orientale della regione balcanica, mentre il tritone crestato della Macedonia, suo parente stretto, popola la parte occidentale dei Balcani. In Europa si trova nel nord-est della Grecia e in Bulgaria, oltre ad alcune popolazioni isolate in Serbia, ad altitudini fino a 1700 m; inoltre questa specie compare anche nel nord-ovest della Turchia. Triturus ivanbureschi colonizza molti tipi di habitat acquatici come stagni, acquitrini, laghi, laghetti, fossi, abbeveratoi per il bestiame o pianure alluvionali. Sulla terraferma predilige boschi ombrosi di latifoglie[2].
