An approximately 400-by-long portion of the 16s rRNA gene sequence has been determined for the venerid clamsChamelea gallina (Chioninae),Dosinia lupinus (Dosiniinae),Pitar rudis,Callista chione (Pitarinae),Tapes decussatus,T. philippinarum,Venerupis (=Paphia)aurea (Tapetinae), andVenus verrucosa (Venerinae). Neighbor-joining and maximum parsimony trees support the results of traditional classification methods at the subfamily level but do not support the concept of a genusTapes. The transversion divergence rate estimated on the basis of the palaeontological record for theC. gallina/V. verrucosa separation and for the Pitarinae is very close (0.14–0.16% per Myr, respectively) to that of ungulates and cetaceans, while the Tapetinae exhibit a much higher (0.36% per Myr) rate.
