diagnosis
Diagnosis. Males of Patrera yukpa n. sp. resemble those of P. florezi n. sp. and P. wiwa n. sp. by having the cymbium similarly shaped, S-shaped, long embolus and bifid retrolateral tibial apophysis (Figs 16 C – E, 21 C – E), but can be distinguished by the very long retrolateral tibial apophysis with both branches similarly-sized, ventral branch rectangular and dorsal branch slender (longer in P. florezi and shorter in P. wiwa), with duckbill shape in retrolateral view (Fig. 20 C – E). Females can be distinguished by their short hood, with ondulations at base (Fig. 20 F – G).
distribution
Distribution. Only know from La Guajira department (Fig. 32).
