Abbreviations: ab = abdomen; ac = auxiliary claw; ch = chelifore; ct = chelifore tubercle on the anterior tip of the first scape; dt = dorsal tubercle; mc = main claw; ot = ocular tubercle; ov = oviger; pa = palp; pb = bulbous tubercle bearing the palp; pp = propodus; pr = proboscis; s = strigilis; t = tarsus.

Fig. 3 in Biodiversity and phylogeny of Ammotheidae (Arthropoda: Pycnogonida)
Fig. 3. Bayesian tree of Pycnogonida based on 179 sequences of the mitochondrial CO1 gene (partitioned analysis). Coloured rectangles show non-ammotheid families, and coloured branches discriminate ammotheid genera. The numbers at the nodes indicate posterior probabilities greater than 0.5. Symbols associated with each taxon name indicate the bias in base composition, as expressed by AT (circles) and CG (squares) skews (see main text for details): blue symbols represent a significant positive bias; red symbols indicate a significant negative bias; uncoloured symbols show insignificant values of skews. Asterisks after taxon names indicate holotype specimens. The arrow at the top of the tree shows the connection with Part 2 of the tree (see next page).
Appendix 2A in Biodiversity and phylogeny of Ammotheidae (Arthropoda: Pycnogonida)
Appendix 2A. Bayesian tree of Pycnogonida based on 135 CO1 sequences (un-partitioned analysis). Coloured rectangles show non-ammotheid families, and coloured branches discriminate ammotheid genera. The numbers at the nodes indicate the posterior probabilities superior to 0.5. Asterisks associated to taxon names indicate holotype specimens. Outgroups were removed for better readability.
Fig. 5 in Biodiversity and phylogeny of Ammotheidae (Arthropoda: Pycnogonida)
Fig. 5. Bayesian tree of Pycnogonida obtained from the concatenation of CO1 and 18S genes (135 taxa). Coloured rectangles show non- ammotheid families and coloured branches discriminate ammotheid genera. The numbers at the nodes indicate posterior probabilities greater than 0.5. Bold branches indicate CO1 (yellow), 18S (blue), or both (red) support in the independent analyses of CO1 and 18S genes provided in Appendix 1. Asterisks after taxon names indicate holotype specimens. Outgroups were removed for better readability.
Fig. 4 in Biodiversity and phylogeny of Ammotheidae (Arthropoda: Pycnogonida)
Fig. 4. Bayesian tree of Pycnogonida based on 159 sequences of the nuclear 18S rRNA gene. Coloured rectangles show non-ammotheid families and coloured branches discriminate ammotheid genera. The numbers at the nodes indicate posterior probabilities greater than 0.5. Asterisks after taxon names indicate holotype specimens. Outgroups were removed for better readability. The arrow at the top of the tree shows the connection with Part 2 of the tree (see next page).
