White Crab Spider

Thomisus sp.


This tiny spider (foto #4) was just under 2 cm long, 1.5 cm wide with an "armspan" of 4.5 cm. It was completely white with a few gray dots or dimples on its abdomen. I found many, many pictures of this spider on the internet, but all only called it a White/Albino Crab Spider. I couldn't find a single site that gave the scientific name. It appears to be in the genus Thomisus. I hope someone can get more "specific." The Wiki link on the right appears to show the spider, but in South Africa, not South America.


This spider was found scurrying along a path (700 masl) in the heat and strong sunshine of the Amazon rainforest of SE Ecuador @ 14:30 in the afternoon. Most of these small crab spiders are normally found on flowers/plants searching for small insects to eat.


The sun was so bright my first pictures were just a bright white "spot" so I picked it up and got into the shade where I got a couple good pictures. I then released it in the shade along the path. I hope it was pleased. It never writes, it never calls . . . . . ungrateful little beast :-)

Thanks Malcolm :-) Actually, I found 2 examples of an undiscovered snake species and the Vivarium in Quito is working on naming it after me. It will be Xenodon rabdocephalus dwainholmesii, the last being my "Latinized" name. I told them they could use "tukupii" if they wanted, but they wanted to use my real name. Your comment reminded me of that. Thanks.

Zlatan & Mauna, there's probably a better chance of it sending word through one of its relatives, which often stop by my desk while I'm working under a light. Thanks both of you.

Thomisus tukupii perhaps... :-)
