The diatom  Phaeodactylum tricornutum  has been used as a model for cell biologists and ecologists for over a century. We have incorporated several new raphid pennates into a three gene phylogenetic dataset (SSU,  rbcL ,  psbC ), and recover  Gomphonemopsis  sp. as sister to  P .  tricornutum  with 100% BS support. This is the first time a close relative has been identified for  P .  tricornutum  with robust statistical support. We test and reject a succession of hypotheses for other relatives. Our molecular data are statistically significantly incongruent with placement of either or both species among the Cymbellales, an order of diatoms with which both have been associated. We believe that further resolution of the phylogenetic position of  P .  tricornutum  will rely more on increased taxon sampling than increased genetic sampling.  Gomphonemopsis  is a benthic diatom, and its phylogenetic relationship with  P .  tricornutum  is congruent with the hypothesis that  P .  tricornutum  is a benthic diatom with specific adaptations that lead to active recruitment into the plankton. We hypothesize that other benthic diatoms are likely to have similar adaptations and are not merely passively recruited into the plankton.
