Remarks.
Only a single male specimen of the monotypic genus is known.
Grynocharina
peltiformis
was originally placed in a basal position on the lophocaterine tree (
Kolibac
2006
: 131) and classified within
Lophocaterini
. However, that tree was constructed after character weighting. A tree under equal weights contains
Grynocharina peltiformis
among the ancyronins in both analyses (
Kolibac
2006
,
2008
). I maintain the position of the species in
Lophocaterini
, following the original classification of 2006 and especially the key of 2010 (
l.c.
) Regarding the probable paraphyletic status of
Lophocaterini
, the question of ancyronine/lophocaterine placement of
Grynocharina peltiformis
is rendered highly irrelevant.
