3-clawed gnaphosid? - dorsal - Cicurina - male

3-clawed gnaphosid? - dorsal - Cicurina - Male
Austin, Travis County, Texas, USA
January 23, 2017
Size: 6mm
Strange beast found in my kitchen sink. This spider screams gnaphosidae to me, but every tarsus has a 3rd claw, supposedly contrary to gnaphosidae. It does not key out to any family using the SONA 2005 family key, and it does not key out to any genus in the gnaphosidae genus key. However, except for the crazy RTA, the palp has similarities to several gnaphosidae genera, such as Gnaphosa, Sosticus, and Synaphosus.

- 3 claws
- endites NOT concave, though color makes them appear to be in photo
- cheliceral retromargin lacks keel/lobes, has 6 denticles instead
- no preening comb on metatarsi III or IV
- shallow trochanter notches
- 1 or 2 dorsal macrosetae on tibia IV
- enormous folded RTA
- ventrally curving cymbium

I'm pretty sure I scanned all the literature SONA 2005 indicates for gnaphosidae, found no match for the palp. I also scanned the WSC for all North American and Holarctic added since 2005 for Gnaphosa, Sosticus, and Synaphosus.

C. robusta or C. varians
I walked the specimen through the various available Cicurina keys. It keys out to a few possibilities in Chamberlin & Ivie 1940. The key appears to walk me to a female-only couplet that can only yield C. bryantae, C. tortuba, C. garrina, and C. robusta.

There's only one prior couplet that I was unsure of. Walking the opposite branch leads me squarely to C. varians.

Of these, Allen Dean lists only C. robusta and C. varians for Texas, so it's likely one of those two. I don't believe we can do better without looking at type specimens. Allen informs me that he often ends up leaving Cicurina undetermined to species.

Paging through SONA 2005, I found a drawing that matches this palp: Cicurina (dictynidae). Investigating...
