Figure 1: Examples of mis-identified
Fossil Coleoptera
Comparison of fossil specimens identified
by S.H. Scudder, with other fossil material. All of the specimens are
approximately 3 mm in length.
(A) Partially fused elytra of Dyschirius
cf. globulosus Say from Two Creeks, Wisconsin, about 11,800 years
B.P. (Before Present).
(B) Single (left) elytron of Dyschirius, also from Two Creeks,
Wisconsin (Morgan and Morgan, 1979).
(C) Single elytron identified by Scudder as "Helophorus rigescens!!"
The specimen is hand-labelled (by Scudder?). "Clay beds near
Cleveland, Ohio" and numbered 14,505. Unfortunately the specimen
is not an Helophorus species; indeed, it does not even belong to
the family Hydrophilidae. The specimen is a member of the Carabidae (genus
Dyschirius); specific determination is impossible.
(D) A left elytron, once again identifed and labelled (by Scudder?) as
"Loricera? lutosa! (det. Sc.) Scarboro "; and on a second
label "Clay beds Scarboro Ca." and numbered 14,559. (In
this case the Ca refers to Canada and not California!). Although this was
identified as a member of the family Carabidae, it is definitely a member
of the Scarabaeidae, almost certainly of the genus Aegialia, and
is, most probably, Aegialia lacustris LeC.
(E) Single (right) elytron of Aegialia lacustris from Two Creeks,
Wisconsin. |
