Plexippus petersi (Common housefly catcher), Ratmalana, Sri Lanka On a mission to ID all my spider pics. I'm think this may be Plexippus petersi but I definitely can't be sure. I've been using the 2012 Sri Lanka Red List to ID (there's a PDF online). I've photographed this spider many times. It's found often around my home. Do offer any alternate ID's because I am less than amateur at IDing spiders! Sri Lanka,animal,animals,arachnid,arachnids,spider,spiders Click/tap to enlarge

    Thank you for your mission, it may be hard, but can ultimately be very rewarding!

    I lack the expertise to comment on this one. A visual superficial match is there but that may not always be enough. Wikipedia mentions the range does not match:

    Plexippus petersi (Karsch, 1878) – Africa to Japan, Philippines, Hawaii

    ...yet eol.org does show an observation in Sri Lanka.

    My advise: if you're on Facebook, search for expert groups and join them. Another thing: when searching Flickr for Sri Lanka jumping spiders:

    https://www.flickr.com/search/?text=sri%20lanka%20jumping%20spiders

    Several similar observations appear, but nobody bothered to ID them. The eyes' size and arrangement match exactly though, so perhaps therein lies the key.     Posted 7 years ago

      Yes, I just saw the wiki page and Sri Lanka is unfortunately not listed. Which throws me off once more since there's three different Plexippus species in the red list and Petersi is the one this spider bears more resemblance to. But like the Chrysilla case, the Redlist can be wrong! I'll see if I can get through to some local experts on this and see. The brown spiders aren't very distinct either so it makes the task harder :/ Posted 7 years ago
