On the other hand, De Ley and Blaxter (2002), using molecular data to revise Nematoda phylogeny, did not recognise lower taxonomic levels under Tylenchidae ( sensu De Ley & Blaxter, 2002). This omission underscores the need for further molecular studies to resolve relationships

Towards a phylogeny of the Metazoa: evaluating alternative phylogenetic
positions of Platyhelminthes, Nemertea, and Gnathostomulida, with a critical
reappraisal of cladistic characters
The “Baeturia and related genera complex”, as defined earlier (De Boer, 1990) by shared aedeagal characters, is identified as the tribe Chlorocystini (sensu stricto). The Prasiini (sensu stricto) are identified as the sister group of the Chlorocystini (sensu stricto), while the genus Muda is recognized as the nearest outgroup. The phylogeny and biogeography of the sister group and outgroup is briefly discussed. Baeturia kuroiwae Matsumura is transferred to the genus Muda. A phylogenetic reconstruction of all 147 species of the Chlorocystini (sensu stricto) is presented, based on 154 characters and 409 character states. The computer program PAUP 3.1.1 (Swofford, 1993) was used for analysing the data; the genera Prasia and Muda were used as outgroups in this analysis. The results obtained from the computer analysis were slightly modified a posteriori, favouring some presumably phylogenetically important characters over strongly fluctuating ones. These final modifications were carried out with the aid of the computer program MacClade 3.0 (Maddison & Maddison, 1992). A complete data matrix and a list of characters and character states are given in an appendix; for descriptions and illustrations of these characters one is referred to previous publications.

Molecular data. The phylogenies of
The allozyme data base of Arntzen & García-París (1995) on midwife toads (Alytes, Discoglossidae) is reanalysed considering each locus as a discrete character. The phylogeny thus inferred differs from the one obtained with genetic distances in the position of A. dickhilleni from the Betic region – it appears that its sister species is the widespread A. obstetricans, not the Mallorcan endemic A. muletensis. This phylogenetic hypothesis agrees with the taxonomic treatment of the genus based on morphology. A testable biogeographic hypothesis is proposed to account for the diversification of midwife toads in Iberia and the Balearics. The postulated underlying geological changes were the spread of inland saline lakes that divided Iberia (16 mY B.P.), the emergence and break-up of the Betic orogen (14 mY), and the formation of the Betic Strait (8 mY). Dispersal over sea channels or during the Messinian Crisis (6 mY) are deemed unlikely on the basis of ecological and biogeographical data.
