Nope, you have been misinformed. The zoological code also covers the
type as specimen (but not necessarily individual).

The glossary of the past and current zoological code says that the
holotype (and the lectotype, too) is The Single Specimen (ICZN-2 & 4)
or A Single Specimen (ICZN-3). We have covered this issue at the
ICZN-LIST (iczn-list at afriherp.org) recently (11-13.x.2005).

Anyway, as a part of an animal can be the type by the ICZN, can we
holotypify whole genomic DNA extracts of an animal stored in a
microcentrifuge tube preserved in a *pretty* cool environment? All
the very best, Cheol-Min
