Comments & ID Thoughts
I went to visit Turkey and in this cave 'Dim Magarasi Cavern' (near the exit), I came across this spider?. This picture was lit by flash as otherwise there would be a red color due to the lighting in the cave system. It was a big spider (my guess would be up to 20-25 cm), sitting motionless on the rocks and had lost two of its legs. I read about cave spiders but would love some feedback.

Hi. This is a male huntsman spider, Sparassidae family. Looks Heteropoda genus.
Not unusual to find them just inside caves. The Heteropoda maxima was discovered in a cave in Laos, largest spider by legspan.
That light pyramid just above the eyes on top over dark is consistent with Heteropoda venatoria, but not a confirmation of species.
Thank you very much for your reply!
Could I ask you, because I’m not that used to arachnid identification, you could tell that it is a male due to the enlarged pedipalps or are there more clues that gave this away to you?
Also, not sure if you have, but would you have/could you advise an id guide for arachnid identification (books or online sources)?
Thank you again!
Hi. First, IDing spiders from photos can be difficult to impossible, but where there is enough detail to see features, this can be narrowed to conclusion. For this, I can only make a suggestion. Firt thin I see to tell gender of the species is the enlarged embolus on the pedipalps,Means this is penultimate or adult male. supporting that is the pattern on the carapace. A dark background with a light pyramid based just behind the eyes. I often see a dark ‘pac-man’ on a light carapace. Females lack this. The abdomen proportions are often smaller compared to females.Another thin… Read more »
One of the resources we use online is the World Spider Encyclopedia. Someone also summarized the species and general ranges from it to Wikipedia. If you search a genus on Wikipedia, either in the text or under “species,” you’ll find the summarized info. We also recommend Bugguide.org. All of my reference books are for North America and Europe, I don’t know what to recommend for your area. We have other site members from Turkey that might have suggestions. A lot of this is just memorizing a set of information about key physical features of each family, genus, and species. Some… Read more »
Tentatively Heteropoda variegata based on general appearance and location. New species for this site. Thanks for sharing. 🙂
Thank you all still for the help, interesting information and recommendations, much appreciated 🙂
Will definitely be back here if I have some more struggles with spider-ID!
