Taxonomy is essential to biological sciences and the priority field in face of biodiversity crisis. The industry scientific publications has made extensive promotion display bibliometric indexes, resulting side effects such as Journal Impact Factor™ (JIF) mania. Inadequacies widely used indexes assess taxonomic are among impediments for progress this field. Based on an unusually high proportion self-citations, mega-journal Zootaxa, focused zoological taxonomy, was suppressed from Citation...

Neponymphes godoii Zamboni, 2001 is redescribed and illustrated based on specimens from the Lower Cretaceous of Northeastern Brazil (Araripe Basin, Crato Formation; upper Aptian, ~114 Ma). The redescription, both adult nymphal stages, shows that external morphological characters N. were fairly similar to those recent members Belostomatini. Hence, morphology in this tribe has apparently not changed much since Cretaceous.
