inflated palpbulbs
« am: 2021-09-22 20:30:03 »
Does anyone know as to why this male Trochosa has partly inflated palpbulbs?
I found this Trochosa (I expect it to be T. terricola) this afternoon in leave-litter.
I collected this specie and it is still unchanged. I have never seen it before.

Inflated palpbulbs are the pest! Some times, I can find relevant details, sometimes I can't.

In this case may be Haralds drawings are helpful:

Trochosa spinipalpis can be excluded by the palp-tibias hair field.

But most time with inflated palps, it is hard to detect the relevant details, 'cause the palp symmetrics are changed.

Thank you! I take it that it sometimes happens (perhaps not to often) ;-) I will try to find sufficiant details like you suggest.

May be the embolus in this case has another shape.

Good luck!
