摘要:
Turinyphia cavernicola Wunderlich, 2008 is one of the two endemic cavernicolous spiders known from the Azorean archipelago (Portugal). In spite of relatively intensive searches, this species is known from only three caves, but with a single sustainable subpopulation restricted to the Algar do Carvao show cave. With an observed extent of occurrence (EOO) of 2 km(2) and an area of occupancy (AOO) around 0,75 km(2), it presents a restricted range, severe fragmentation, and continuing decline in EOO, AOO, habitat quality, number of locations and subpopulations caused by the ongoing threat from pasture intensification and tourist activities in the cave systems.
