Gymnetron tetrum
(Fabricius)
var.
subrotundatum
Reitter, 1907
Reitter (1907)
described the variety
subrotundatum
based on small specimens of
R. tetra
from
Germany
,
Hungary
, Dalmatia and
Greece
, in our opinion giving an infrasubspecific rank to this name according to Art. 45.6.1 of the ICZN (1999). However, since
Zumpt (1933)
treated this taxon as a subspecies of
R. tetra
, the name
subrotundatum
must be considered as available according to Art. 45.6.4.1. Subsequently, this name was consistently placed among the synonyms of
R. tetra
(
Hoffmann 1958
;
Smreczyński 1976
). At HNHM we examined three
syntypes
of this taxon and designated as the
lectotype
a female labelled “Dalmatien, Budua [presently in
Montenegro
], Reitter [printed] / subrotun-, datum [sic] var., 1905 [handwritten by Reitter] /
Holotypus
, 1907
Gymnetron (Rhinusa) tetrum Fabr. var. subrotundatum Reitter
[label arbitrarily handwritten by a museum curator] / Coll. Reitter [printed]”. The other two specimens, a male and a female, are labelled “Dalmatien, Budua, Reitter [printed] /
Paratypus
, 1907
Gymnetron (Rhinusa) tetrum Fabr. var. subrotundatum Reitter
[label arbitrarily handwritten by a museum curator] / Coll. Reitter [printed]”. We agree with Reitter's original opinion that these specimens are only small specimens of
R. tetra
.
