Anyphaenidae?

Any thoughts on any of these?

We're willing to put in the work moving them if anyone is interested in supporting (or disagreeing with!)our suggestions.

I still don't have a grasp on these

I tried reading that PDF, but it doesn't help that the only habitus image is Arachosia cubana. I don't think I can separate them out by range because I'm not even sure I've got the genus right. I need a decent set of drawings or images with the field markings described.

I can't argue with any of those first group being moved to the ghost spider family page.

Ok, we moved that first set.

Yes the link is not too helpful other than some of the descriptions and the maps. We are separating images based upon those images already ID'd to genus on BugGuide. Anyphaena does look different from Hibana in those. Maybe we just have to wait till we get better resources. :(

Anyphaenidae

Anyphaenidae vs. Clubionidae

1. Clubiona have hair on the front of the abdomen that points out over the carapace. But I'm pretty sure I've seen some ghost spiders with the same thing. The weird thing is, my guide drawings don't show those hairs on the ghost spiders.

2. Clubionidae do not appear to have patterns on the carapace. This could be a big clue to separating them.

3. Clubionidae have a anterior and posterior middle eyes closer together than Anyphaenidae, and sometimes in Clubionidae the posterior median eyes are further apart instead of equidistant like most Anyphaenidae.

Anyphaenidae

Hibana
- Anterior eyes are subequal
Wulfila
- Tibia I about one and a half times as long as carapace
- anterior median eyes smaller than posterior median eyes
Anyphaena
- Tibia I not or hardly longer than carapace.
- Carapace usually with two darkly pigmented longitudinal bands.
- male chelicerae not elongated

It looks to us that Anyphaenids

have darker shading on the carapace, contrasting spots or blotches on the abdomen, and more spiny legs.
While Clubionids have more unicolor carapace and abdomen and less spiny legs.
But....

More work...

Okay, I culled out one Hibana specimen (I hope -- the image with the green leaf BG), and will try to look at more. With all the anyphaenids, a ventral view of the abdomen is most useful. E.g., in the genus Hibana, the tracheal spiracle (which I usually mistype as "spiral") is closer to the epigastric furrow than it is to the spinnerets. In the other genera in the Anyphaenidae, the spiracle is at about the midpoint.

Just noticed that Ken has provided a useful illustration:
