Subject: Another Possible Problem with Naming Conventions for Panstem=

This one occurred to me during a discussion with Jaime Headden and Mi=
ckey=20
Mortimer.

Hypothetical situation:

CLADOGRAM (requires monospaced font)
--+--Alpha (extant)
  `--+--Beta (extinct)
     `--+--Gamma (extant)
        `--Delta (extant)

Suppose someone names:
    _Betoidea_ =3D Clade(_Beta_ <- _Alpha_)

Later, someone names a panstem/crown pair:
    _Gammadelta_ =3D Clade(_Gamma_ + _Delta_)
    _Pangammadelta_ =3D Clade(_Gammadelta_ <- extant non-gammadeltans=
)

As can be seen, _Pangammadelta_ would be a junor heterodefinitional s=
ynonym of
_Betoidea_. The convention of having the total group starting with "P=
an-" would
be ruined, because the proper name for the clade (assuming the cladog=
ram is
ccorrect) is _Betoidea_.
