Introduction

Monophyly of Callipallenidae was not recovered in morphological and total evidence analyses by Arango (2002) or Arango & Wheeler (2007).

The callipallenids are closely related to nymphonids, forming a strongly supported clade based on the presence of an oviger apophysis in males, and the development and type of larvae. However, the internal affinities of the Callipallenidae-Nymphonidae group remain to be tested, especially after inclusion of more callipallenid genera. Also, relationships of the Callipallenidae-Nymphonidae group with other pycnogonid lineages are not clear, as the support for the grouping with ammotheids is very low (Arango & Wheeler 2007).

Diagnosis

Chelifores present, scapes 1 or 2 segmented, chelae usually small, functional; palps either lacking, of 1-4 segments in males only, or only rudimentary knobs in both sexes; ovigers 6, 9 or 10-segmented, in both males and females, generally with compound spines. Legs long or short, with or without auxiliaries. Cement glands ventral.
