Ai Ai Ai you should have stayed longer, the island is worth it!
Nevertheless a very nice report and beautiful pictures!
Very interesting, but not clear for me, is your Dolichophis caspius. From Kos (only jugularis is known?) or Kalymnos?
already in 2006, Matt Wilson and also some Dutch people described both species of Dolichophis for Kos for the first time. This year Matt and Carl confirmed it again. In Kalymnos only caspius has been found so far... I saw one caspius on Kalymnos this year.
What is more ambitious, is trying to find vipers on Kos. Schneider reports one specimen from Kalymnos in 1983 (PDF-144 in the database)
But I couldn't find any reliable records for Montivipera on Kos:
Chondropoulos lists in his checklist (PDF-1742) the following reference: (NILSON & ANDREN 1986; AD obs., outskirts of Kos town/4.8.87)
Please help me out: what does that "AD" mean? Additional data? Autor data? so obs. from Chondropoulos himself?
If you check the NILSON paper (PDF-7536): on figure 31, Kos is pointed out for a locality data but in the text it actually gives the reference: Grillitsch &Tiedemann (PDF-3128).
They state in the same year 1986: "Auf Grund mangelhafter faunistischer Kenntnis über dieses Gebiet sind trotz der bisher erfolglos verlaufenen Versuche, die Bergotter auf Kos und Rhodos aufzufinden, noch weitere Neumeldungen dieser Viper für dem asiatischen Festland unmittelbar vorgelagerte Inseln
zu erwarten."
So actually nobody ever really found them there?
Still Andre, I love it, you made it your main goal to find them on Kos!!!
There are probably a lot of things we can still discover on that island. Hemorrhois nummifer is by my knowledge only known from a specimen that was first wrongly determined as a young Elaphe quatorlineata long time ago. Trachylepis aurata is so called known from one museum specimen, collected maybe 100 years ago. Pelobates needs a bit more confirmation. Eirenis might be present, etc....
