Comments: Monrós (1945: 146) described Agathomerus varians as a new species, but later on, in an addendum in the last page of the same work (p. 155), he informed that A. varians is actually a synonym of A. quadrimaculatus Guérin, 1945 , which had been published a few months earlier. The name Agathomerus varians Monrós is therefore unavailable, according to Article 11.6 of the Code (ICZN, 1999), and thus cannot be considered as a junior synonym A. quadrimaculatus Guérin.
