It seems that the genus Lobeza is not yet undoubtedly assigned to a subfamily. The genus is thought to be part of Heterocampinae, however, with the lack of morphological or biological evidence, this hypothesis remains controversial. 
Franziska Bauer, an expert on butterflies from the Senckenberg Research Institute, Museum for Zoology in Dresden, Germany, helped me identifying the genus.
