Etymology

Etymology Tabiskey means ‘ the man with ten feathers ’. It is a Cuica term to describe the leader of the people, who guided them in peace or war and had the principal rule in important decisions. He was selected from among the priest ’ s sons.

Diagnosis

Diagnosis Pseudonemesia tabiskey sp. nov. differs from P. parva and P. kochalkai by the clavate setae on dorsal and lateral sides of the abdomen (Figures 6 (a,b), 7(a,b), 9(b,c)). In addition, males of Pseudonemesia tabiskey sp. nov. differ from the other two species of the genus by the presence of one short and apically rounded spine located retrolaterally on tibia I (Figures 1 (g,h), 3(a – c), 6(f)).

Biology and Ecology

Habitat The specimens were collected using pitfall traps. The containers were partially filled with a saturated saltwater solution, left in place for 5 – 7 days at 2500 m asl. All specimens came from a transitional forest between Andean rainforest (1800 m asl) and the paramo vegetation (> 2700 m asl) (Figure 10 (a,b)). The average temperature was about 15 – 17°C and the annual rainfall, measured nearby, was> 900 mm. Other mygalomorph spiders collected in this area were Linothele sp. (Dipluridae) and Bolostromus sp. (Cyrtaucheniidae).

Distribution

Distribution Known only from the type locality, in Venezuelan Andes: Trujillo state (Figure 12).
