FIGURE 2. Relationships among 16 in New species of Ilanga (Gastropoda: Trochoidea: Solariellidae) from the Indo-West Pacific
FIGURE 2. Relationships among 16 Ilanga species. Bayesian tree based on COI sequences, with outgroups (Elaphriella leia, MNHN IM-2007-18539; Elaphriella sp. 7, YK1384; and E. khantaros, MNHN IM-2009-15192) removed for clarity. Taxon labels are GenBank accession numbers and support values are posterior probabilities (PP). New GenBank sequences are in red type. Branches with PP <50% were collapsed, PP not shown for intraspecific relationships. Note that Ilanga herberti n. sp., I. helicoides n. sp. and Ilanga 18 are missing from the tree as although molecular data exist, there are no COI sequences for these species. Ilanga 19 was erroneously published as Microgaza fulgens in Williams et al. (2008) but is not discussed in this study as there is no voucher material. Other species are missing because there are no live-collected specimens.

FIGURE 5 in The Cainozoic to present-day record of Circum-Mediterranean, NE Atlantic and North Sea Cantharidinae and Trochinae (Trochoidea, Gastropoda)-a synopsis
FIGURE 5. Cainozoic species diversity of Cantharidinae and Trochinae (red bars) compared with the stable isotope record (δ18O) of Zachos et al. (2001), which can roughly be read as climate record. Important geodynamic and climatic events are given in yellow (MMCO = Middle Miocene Climate Optimum, MSC = Messinian Salinity Crisis). No clear relation between global climate, geodynamic events and trochid evolution can be deduced form the data. Note that the endemic Sarmatian radiation is not shown in the figure.
