Hi! Would you be so kind to take a look and identify?

Crab Spider

Hi Alexander,
We do not recognize this beautiful spider and we have not had any luck finding a matching image on the internet.  We can tell you that this is a male based on the developed pedipalps.  We suspect this is an Orbweaver, or perhaps a Crab Spider.  Perhaps one of our readers will be able to assist in the identification.

Hi Daniel and Alexander:
It does look like a Crab Spider (family Thomisidae), probably Ebrechtella tricuspidata. It also goes by the synonym Misumenops tricuspidata. Either way, it is the single species in the genus. It is widely distributed, eastern and southern Europe to China, but is apparently uncommon throughout its range.  Several web sites refer to it as the Triangle Crab Spider, but given its range it may have other common names as well. Regards.  Karl

Welcome back Karl, and thanks for the identification.  We were wondering if cooler weather and shorter daylight hours might be providing you with additional time to research some of our unidentified species.

Thank you very much!
You’re doing great job!

Hi Daniel. We are still pretty busy here but you are right about the cooler weather and (hopefully) more free time being on its way. Actually, the main reason you haven’t been seeing much from me recently is that we have been having huge issues with internet connectivity. We moved back to the country a few years ago and unfortunately our property is in some kind of cyber dead zone. This summer has been particularly bad, with internet connectivity and speed ranging from poor to non-existent. However, I believe we may have finally defeated all the problems and things are running rather smoothly at this time (fingers crossed). Also, you and your growing flock of helpful readers aren’t leaving many unresolved mysteries anymore. I enjoy seeing the increased interaction and participation. In my spare time I have been working steadily to identify and catalogue all the insect pictures (and spiders, etc.) that I have taken over the years but it has been a slow grind. Not being able to access the internet doesn’t help. I if I ever get caught up it will probably be years from now, but I hope to have a substantial number uploaded to my photo site over the next few months. Good luck and keep up the great work.  Karl

Hi Karl,
Your input is always greatly appreciated.  Please send us a link to your photo site when it is ready for more public consumption.
