Four pads in the fourth and fifth oncopods (oncopods="legs").
Soles on foot (also known as creeping pads): Four complete creeping pads, without presence of the vestigal fifth one in all oncopods.
Seven plicae pass to the ventral side between oncopods.
Oncopods pale or light yellow, contrasting with the darker body.
Both males and females of the new species have more oncopods than other Neotropical Peripatus (sensu stricto) and other Costa Rican onychophorans (Epiperipatus and Macroperipatus).
Based on a morphometric analysis, Monge-Najera & Morera (1994) suggested that the number of oncopods is simply a function of the animal's length, but the correlation has important exceptions.
The Onychophora's ancestors were a few millimeters long, lived under water and had few but long oncopods (Monge-Najera 1994, 1995), so we suspect that at the extreme size of 22cm, P.
Length, oncopods and speed: The evolution of larger body sizes may increase the probability of surviving predator attacks but obviously this line of defense was not developed in the mud flat or the terrestrial community.
