FIGURE 7. Taxon Area Cladograms for A in Phylogeny and an integrated biogeography of Acanthotetilla Burton, 1959 (Demospongiae: Spirophorida: Tetillidae): two-way traffic on the peri-African track
FIGURE 7. Taxon Area Cladograms for A. Mycale immitis (Schmidt, 1870) group; B. Mycale australis (Gray, 1867) group [= M. (Grapelia) spp. sensu Van Soest et al. (2011)]; C. Thrinacophora Ridley, 1885; D. Acarnus Gray, 1867; E. Didiscus Dendy, 1922; F. Placospongia Gray, 1867; G. Rhabderemia Topsent, 1890 and H. Petromica Topsent, 1898. A–E from Van Soest & Hajdu (1997). F. from Nichols and Barnes (2005). G. from Hajdu & Desqueyroux-Faúndez (2008). H. from List-Armitage & Hooper (2002). Areas utilized in the original biogeographic analyses were transformed into Spalding et al.'s (2007) provinces (Table 4). The black circles indicate cladogenetic events separating the areas considered in the TAC-TAC comparisons performed.
FIGURE 6 in Phylogeny and an integrated biogeography of Acanthotetilla Burton, 1959 (Demospongiae: Spirophorida: Tetillidae): two-way traffic on the peri-African track
FIGURE 6. Panbiogeographic map elaborated from both the current distribution of Acanthotetilla spp. and its phylogenetic cladogram (Fig. 5) by the hand method listed in Henderson (1989), subsequently adapted by Hajdu (1995) and in the present study. Arrowheads represent the polarity of each track. Multiple arrowheads in a single track imply several polarities inferred for that track. Letters in square: C = A. celebensis, E = A. enigmatica, G = A. gorgonosclera, H = A. hemisphaerica, R = A. rocasensis, S = A. seychellensis, W = A. walteri.
FIGURE 5 in Phylogeny and an integrated biogeography of Acanthotetilla Burton, 1959 (Demospongiae: Spirophorida: Tetillidae): two-way traffic on the peri-African track
FIGURE 5. Taxon Area Cladogram (TAC) for Acanthotetilla sp. obtained by substituting each terminal taxon by the provinces of Spalding et al. (2007) where they occur. 12, Tropical Northwestern Atlantic. 14, Tropical Southwestern Atlantic. 19, Somali / Arabian. 20, Western Indian Ocean. 29, Tropical Northwestern Pacific. 30, Western Coral Triangle. Spalding et al.'s Realms are identified on the right side. Provinces listed in italics above each node are reconstructions by DIVA 1.1 (Ronquist 1996) of likely ancestral areas.

FIGURE 4 in Phylogeny and an integrated biogeography of Acanthotetilla Burton, 1959 (Demospongiae: Spirophorida: Tetillidae): two-way traffic on the peri-African track
FIGURE 4. Most parsimonious cladogram (Nelson consensus = majority-rule consensus with other compatible groupings) for the phylogenetic relationships of Acanthotetilla spp. and outgroups. Numbers above the nodes represent apomorphic, homoplastic and (underlying-) synapomorphic character states. See text for a list of characters and their states utilized in the present analysis. This tree has 29.86 steps, CI = 0.89, HI = 0.10, RI = 0.93 RC = 0.83. Numbers underneath each node are Bootstrap Support for unweighted analyses/ Bootstrap Support for subsequently weighted analyses/ Bremer support for unweighted analyses/ Bremer support for subsequently weighted analyses/ Bayesian credibility (values between paretheses). * nodes present in the Nelson consensus but not in Bootstrap or Bremer trees.
