Overview

Harpactea hombergi is genus of spiders in the family Dysderidae. It is native to Europe.

Harpactea hombergi faces severe population declines primarily due to habitat destruction and fragmentation of its specialized cave and rocky crevice environments. Urban development, quarrying activities, and changes in groundwater levels have significantly reduced the availability of suitable microhabitats this endemic spider requires for survival.

Threat summary

Habitat
