Type species. Grynocharina peltiformis Reitter, 1877 [by monotypy] Leveille , A. 1910: 24. Kolibac , J. 2005: 57 (redescription). Kolibac , J. 2006: 111 (phylogeny). Kolibac , J. 2010: 35 (key) 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.
