Other material examined. COLOMBIA, Nariño: Vereda Ricaurte, Reserva Natural La Planada (4°16′45″N; 74°46′22″W) , 269m, ♀ 1, 12.III.1992, C. Valderrama leg. ( IBSP 213430 ) ; ♀ 1, 20.III.1992, C. Valderrama leg. ( IBSP 213428 ) ; ♀ 1, 20.III.1992, C. Valderrama leg. ( IBSP 213427 ) ; ♀ 1, 21.III.1992, C. Valderrama leg. ( IBSP 213426 ) .

Etymology. The specific epithet is a patronym in honor to Adriano B. Kury, who has greatly contributed to taxonomic and systematic studies of harvestments of the world.

Diagnosis. Males of Patrera kuryi n. sp. resemble those of P. shida Dupérré & Tapia, 2016 by the elongated cymbium, and narrow, tubular ventral tegular process and basal lobe on the base of tegulum (see Dupérré & Tapia, 2016: figs 46̅47), but differ by having the retrolateral tibial apophysis with the ventral branch wide-based (base thinner in P. shida ) and by the entire, very thin tegular process (bifid in P. shida ) ( Fig. 28C ̅E). Females can be diagnosed from other species by the long, finger-shaped hood, and small, oval spermathecae ( Fig. 28F ̅G).

Abdomen: length 2.0, epigastric furrow 0.7 from tracheal spiracle, spiracle 0.8 from base of spinnerets. Palp: retrolateral tibial apophysis bifid, large, with the ventral branch wider than dorsal one, which is extremely thin; cymbium approximately as long as tibia; subtegulum longer than wide; tegulum longer than wide, with a long, thin ventral tegular process closely related to the embolus; median apophysis short, curved and medially situated; embolus short, laminar, curved, apically filiform, with narrow base and proximally inserted on the tegulum ( Fig. 28 C–E).

Female (Paratype, IBSP 213429). Coloration as in the male, except the abdomen dorsally uniformly gray ( Fig. 28B ). Total length 4.2, carapace length 1.83, width 1.49. Clypeus height 0.06.
