Jumping Spider - Phlegra hentzi

Moved

Kevin, it looks like the P. fasciata and P. hentzi question hasn't been figured out for sure yet. I'll move it to the existing page for now, and if information comes in supporting fasciata, I'll change the page. Thanks for all your help.

To be quite honest, I didn't

To be quite honest, I didn't even know there was this question until last night. Have you seen this paper:

Logunov, D. V. & S. Koponen. 2002. Redescription and distribution of Phlegra hentzi (Marx, 1890) comb. n. (Araneae, Salticidae). Bull. Br. arachnol. Soc. 12: 264-267.

Platnick lists both and the indication seems to be that one is essentially an Old World species and the other New World, but I've not yet seen the article mentioned above.

I haven't seen the paper

And I'm not sure which one is the Old World species and which is here.

hentzi vs. fasciata

I now have the article; long story short: Phlegra hentzi is the North American salticid (actually Eastern USA and Canada); Phlegra fasciata is the Old World species (Palearctic). Which leads me to the observation that the Nearctic Database has an entry for Phlegra fasciata (and two NA records are listed) and uses one of your images, while Phlegra hentzi has no image.

Perhaps someone with experience can tell them apart visually, but the article suggests that a genital examination is necessary -- although for all practical purposes (certainly BG purposes), distribution should be sufficient, I would think.

Phlegra hentzi

Kevin, thanks for doing the detective work. Now we know this is the appropriate name for the North American spiders.

Looks a lot like Phlegra fasc

Looks a lot like Phlegra fasciata, doesn't it -- three stripes on abdomen and two on prosoma, metatarsi shorter than tarsi, brick red around eye region (Kaston)?
