RE-DISCOVERY #3
Scotinella pennimani Platnick and Chamé-Vázquez, 2024 (Phrurolithidae) was described just last year from specimens collected in 1967 (58 years ago). We found this lady in Okefenokee NWR on Trembling Earth Nature Trail just north of Stephen C. Foster State Park in SE Georgia.

RE-DISCOVERY #2
Our trip to Okefenokee NWR has resulted in another re-discovery of a long-lost species. Ceratinopsis sutoris Bishop & Crosby 1930 was last seen in 1927 (98 years ago!) and we collected several males and females. The species has a orange-red carapace with black around the eyes.

RE-DISCOVERY #1!
Our trip to Okefenokee NWR has already resulted in a re-discovery of a long-lost species. Ceratinopsis bona Chamberlin & Ivie, 1944 was last seen in 1943, 82 years ago. In addition to possessing genitalia that match the descriptions, their black tibia IVs are also diagnostic.

Day 4 of our Okefenokee NWF collecting trip took us to Mixons Hammock east of Stephen C Foster State Park. We canoed the two miles and then sampled mossy patches and magnolia litter in cypress swamps. Not the most productive, but we found many linyphiids for study.

Day 3 of our collecting trip was to the east side of Okefenokee NWF (a 1.5hr drive around the southern edge) where we collected in swampy thatch/moss patches along the Chesser Island boardwalk. Found lots of erigonines, a pygmy rattlesnake, and a water moccasin. Didn't collect the snakes, though. 🙂

Day 2 of our Okefenokee spider collecting trip went well. We were joined by Brett Tyler, a spider enthusiast at Georgia DNR. To collect, we vacuumed under Sphagnum moss mats and among Cypress knees in wet swamps and jumped off of boardwalks to get to emergent wetland vegetation. Long, tiring day.

Day 1 of our Okefenokee NWF trip completed. We canoed to Billy's Island (~2mi.), collected spiders all day via litter sift and vacuum, and canoed back to camp. Very productive and hopefully we collected some lost species.

One of the most interesting morphological quirks of this spider is a character I have never seen in any other spider, regardless of taxonomic family, and that is the presence of two stout spines on the male clypeus. The clypeus is on the "face" just below the anterior eyes, above the chelicerae.

A fourth spider we're searching for at Okefenokee NWF later this month is Floricomus setosus. This tiny spider was last collected 82 years ago, in 1943 and was previously found "E. side of Okefenokee Swamp" in 1933. Only one male and two females have ever been collected.

A third spider we'll be searching for in Okefenokee Swamp is Floricomus floricomus. A tiny, 1.5mm spider with a distinct plumose setae-covered horn on the head of males, this spider was first discovered in 1922 when it was CUT OUT OF THE STOMACH OF A TOAD that was hopping around in Okefenokee Swamp.

Another spider we are searching for on our Okefenokee NWF journey is Idionella titivillitium. It was first collected in 1912 on Billy's Island at the edge of the swamp, which is where we are traveling to in late October. It was collected, "by sifting decaying leaves in dense shade at edge of swamp."

One of the spiders we are searching for on our Okefenokee NWF trip later this month is Ceratinopsis bona. Described from southeastern Georgia, this specimen hasn't been seen since it was collected for that description in 1943. It is reddish brown with black around the eyes with a gray abdomen.

This was one super-gravid spider!
I hear people sometimes think spiders look like ticks and usually it seems a bit silly to me, but in this case I can make an exception.

For the last day of #InverteFest, I give you a male of Ceratinops latus (Araneae: Linyphiidae) from Big Oaks National Wildlife Refuge in SE Indiana. This lil guy is about 1.5 mm in length.

An infuriating article from U. Rochester school newspaper in 1957 that reflects the scientific attitude at mid-century towards taxonomy, biodiversity, and the perceived value of specimen collections.

A 12-shot stack of the curious silkhenge spider egg sac (more info here: www.rainforestexpeditions.com/we-solved-an...). This is currently being studied by brilliant arachnologists, including the amazing @henriquesbio.bsky.social. It's still not clear what type of spider builds this structure.

For #Invertefest, I present to you a trapdoor spider from Alabama that plugs the opening of its burrow with its abdomen when it gets scared. This adorable critter is Cyclocosmia truncata (Araneae, Halonoproctidae).
