 Titiotus Spiders

 This spider is a species within the genus Titiotus, which is native to California. It is often mistaken for a brown recluse because of the colouring and faint violin shape on the abdomen. Titiotus superfically looks like a brown recluse spider, or desert recluse spider, but isnít. Titiotus has eight eyes, whereas brown recluse-type spiders have only six. Due to its prominent violin marking and large size, Titiotus is one of the most commonly reported species. The venom of these spiders is not reported as harmful to people. They belong to the spider family Tengellidae includes 57 described species; 41 of these occur in the United States, with 33 of these 41 species having been described by Platnick and Ubick in their revisions of Socalchemmis (2001), Anachemmis (2005), and Titiotus (2008). In the U.S., Licranoides occurs in the Appalachian Mountains (Platnick 1999), Lauricius from Arizona to New Mexico and north into Colorado, and the remaining U.S. genera (Socalchemmis, Anachemmis, and Titiotus) are found in California, with some extension to the north and south (Ubick and Richman 2005).

TITIOTUS sp.

Titiotus spiders are endemic to California and are often mistaken as I did until kindly corrected by Dana, as desert recluse. I couldn't find any common name for these spiders. Titiotus species seem to prefer steep, rocky canyon slopes near high montane streams. At lower elevations, including the Coast Ranges, Titiotus species occur mostly in forests, especially oak and mixed evergreen, but also in rocky grasslands. These spiders are also strongly cavernicolous; almost half of the known species are recorded from caves, where they may be quite abundant. Their egg sacs are spherical, about 1.5 cm in diameter, with a papery outer covering, and could be found suspended from the ceiling by a thick cord of silk about 1Ė2 cm long.

At first , I had identified them as brown recluse, never having seen them before and not knowing they actually have a violin shape on their back...I thought the whole body was the shape of a violin. Anyhow, I've found online that the way to be sure is by their eye pattern, which this species do not match the recluse eye pattern. I wonder if this is a huntsman spider? They are fairly large, and I have no idea what stage of maturity they are. In two of the pictures I sent you prior, one of which was on the tarp and had an eyelet nearby. The other I placed my ring next to, both the eyelet and the ring are the size of a quarter. I do agree, they have a striking resemblance to the recluse which thoroughly creeps me out... Bret

Reply: The closest I can come up with is maybe one  of the titiotus sp. http://en.wikipedia.org/wiki/Tengellidae - glen

Hi Glen, Wasn't quite sure where to submit pictures. Found this gal on my wall months back. What threw me off, however, was the sheer SIZE of this monster. It screams recluse, but, I would say a GOOD three inches with legs and I've not seen any much larger than a quarter (this thing was larger than a silver dollar!!!) I was too afraid to scale it in fear it would run off and come across my three year old. Hoping you can help!!! I live in the Central Coast of California, USA.

Dear Glen, I stumbled upon your website as I was searching for the identification of this spider. AWESOME site! Within the last couple days, I found two of the same kind of spiders in my house, one in my shower while I was showering (I just happened to spot it by my feet as I was shampooing my hair!), and the other in my sink in my other bathroom after I ran the water for a short bit. (I was out of town for a couple weeks so didnt run the water until the last few days. I think they were in the drains?) I live alone in a very rural area of Lake Elsinore, CA. Its all dirt and wide open hills and brush all around my house and am the only house off a long dirt road. I have lived in this house for 2 years and have never seen these before. I have found black & brown widows, sun spiders, and small scorpions in my house, but this is new. I am concerned that they may be Desert Recluse spiders? I know that we dont have the brown recluse spiders out here, but I know we have the desert recluse (most common here) and some other recluse spiders that are not so common. Its hard finding good pictures of the desert recluse on-line or any other kind, they are all mostly of the brown recluse. Could you please help with identifying this? (I hope the pictures are good enough for I.D.) I would REALLY REALLY appreciate any assistance! PS - These guys are bigger than a half dollar! Yuck! Sincerely, Caroline

Greetings, We live in the Transverse Range of mountains between L.A. and Bakersfield in Lockwood Valley, elevation 5200'. We are about 60 miles west of the Antelope Valley...It's not technically desert but it is a very dry, Pinyon and Juniper woodland type. This is the third of this type of spider I've found in our house in the 18 years we've lived here so I'm not overly phobic about it, but my wife and daughter are fairly beside themselves as they have twice encountered them on the way to the loo at night! I recently read a piece in a journal that describes this species living in Woodrat nests, of which we have many on our property and the rat's themselves are quite pesky as they like to steal shiny objects from the barn! Anyway, I'm pretty certain of the identification of this spider as I have counted it's 6 eyes! What say you? Thanks for a your fabulous website and resource! Ron
