Identification
Members of Poeciloneta can be distinguished from other linyphiid by the combination of male , particularly the structure of the paracymbium and embolic division, and female epigynal configuration. Specific diagnostic characters vary by and require examination of genitalia; no single external morphological trait reliably separates all Poeciloneta species from related genera.
Distribution
