Diagnosis
ReferenceDiagnosis
M. G. Vucetich et al. 2015P. dichroplax differs from the other species of Phugatherium by the deep h.s.e. of pr.IIb of m3 that reaches 50% of the prism width. In p4 h.2i. and h.3i. reach 75% the prism width defining a long drop-shaped C3; pr.I has thin walls more lingually divergent than in the other species. M3 with external fissures in almost every prism, deeper (up to 35% the width of the prism) in prisms 4 and 5, intermediate in depth between P. novum and P. cataclisticum.
