The platnicki Group
DIAGNOSIS: Males with fusiform to elongated palpal bulbs with a complex conductor; both sexes lack the prolateral ventral macrosetae of the femora I and II, and also have relatively enlarged femora IV, as in the previous group. Two species ( N. silvae and pithecia) have the copulatory bulb partially fused with the cymbium (fig. 86D, F).
This group comprises three species that seems to be restricted to the upper Amazon region of Peru and Ecuador. All the species were found on the foliage of trees in tropical rainforests.
