Species in this genus are generally very slender. The
morphometrices often have wide ranges and there are not many other
characteristics for separating species. Differences among species
exist in the surface characteristics of the cuticle which may have
longitudinal ridges and a tiled appearance. Greater detail of the fine
structure of the cuticle is revealed by SEM but the technique has not been
used for most of the described species (Brostrom & Holovachov. 2001) |
