Figure 4 Pylogeographical convergence between mysid shrimps in the Sierra de El Abra and the mtDNA of Astyanax cavefish (right). Both aquatic species harbor the evolutionary signature of a phylogeographical discordance, where genetic markers of populations in central Sierra de El Abra are extremely distinct from the rest of the populations. Nuclear tree (left) based on the consensus of isoenzymes, RAPDs, microsatellite, and genomic sequences. a) Pachón as representative of northern populations. b-c) Sabinos and Tinaja as representative of central populations. d) Chica and Chiquitita as representative of southern populations.

Figure 8 Most supported phylogenetic tree, according to character matrix in Table 2, of the genera Mesocrista, Platicrista, Itaquascon, Astatumen and Meplitumen (phylogenetic tree values: consistence index = 0.91; retention index = 0.83). 0 = Ancestor with ordinary AISM (i.e. not wide and flat and with caudal processes pointing postero-laterally), stylet supports present, spiral thickening present only after the stylet supports, ordinary stylet furcae and placoids. 1 = AISM became wide and flat, stylet furcae reduced slightly, placoids became elongated; Mesocrista maintained these characters. 2 = Caudal processes of the AISM pointed laterally; apices of the caudal processes of the stylet furcae became non-swollen. 3 = appearance of spiral thickening also on the anterior buccal tube; this line gave rise to Meplitumen. 4 = AISM became wider and their caudal processes reduced; Platicrista maintained these characters. 5 = Stylet furcae small and with reduced caudal processes, placoids reduced to a single, very thin, bar or absent, stylet support slendered; Itaquascon maintained these characters. 6 = Stylet supports disappearance, spiral thickening present also on the anterior buccal tube; this line gave rise to Astatumen.
