Evolution & Systematics

Figure 1 shows a phylogram obtained from an analysis using 32 combined spermatozoal and spermatophore characters of 51 species of the infraorder Anomura (Tudge 1997). Results show that Clibanarius corallinus is closely related to another member in the same Genus Clibanarius erythropus (Tudge 1997). Nevertheless, results also show that the superfamily Paguroidea is not a monophyletic group and is paraphyletic with some species of the superfamily Galatheoidea (Tudge 1997). This contrasts with previous phylogenetic analyses using adult somatic morphological characters, which suggest Paguroidea is monophyletic as shown in Figure 2 (McLaughlin 1983).

A: Characters associated with development of the perforatorial chamber in spermatozoa.
B: Anomura-characterized by the shift of microtubular arms from the nucleus to the cytoplasm.
C: Appearance of the pedunculate spermatophore.
D: Restriction of the number of microtubular arms to three.
E: Clade of Clibanarius species separated from the other traditional diogenids.
