Tegenaria sp. ♂ from Georgia

<< < (2/3) > >>

Armen Seropian:
Well, my guess that the male and female are the same species is based on the almost exact place of finding within a 1 day interval.
Yes Simeon, the female indeed looks like T. chumachenkoi, but when I've outlined both epigynes (yellow one - chumachenkoi, the difference in proportions of height and width were quit obvious for me (but yes, it may be the case of perspective).

Simeon Indzhov:
The width of an epigyne is a very variable character in my experience so I wouldn't use it unconditionally as an argument against conspecificity. Which of course doesn't directly imply the two are conspecific :D . A very interesting case, anyway. Finding more material at the locality, especially females, may be very useful.

Martin Lemke:

--- Zitat von: Simeon Indzhov am 2021-09-22 21:42:10 ---It may easily be an undescribed species species or the undescribed male of one of the species described only from females from the Caucasus?
--- Ende Zitat ---

Or still a the first record of a known species for Georgia.

The first strategy is to consult the key at https://araneae.nmbe.ch/genkey/7/Agelenidae?lang=en

Another Idea: I ask Stefan Otto (https://stefan-otto-spiders.de/ & https://caucasus-spiders.info/), a German specialist of Georgian spiders.

Simeon Indzhov:
As somebody with multiple first records for my country, I don't use the country filter at Araneae or current checklists :P . My limitations were those of Araneae - I didn't check species from the Levant, Iran or further East in Asia though, I admit.

Martin Lemke:
Stefan Otto schrieb mir gerade, dass es nicht Tegenaria abchasica ist. Er ist mit Armen in Dialog.

Ich hoffe wir bekommen die Lösung, wenn es eine gibt, hier präsentiert wird. Sowas ist schließlich immer sehr spannend.
