Taxonomy In the opinion of Göcke & Janussen (2013: 80), the differentiation between the species M. benedeni and M. charcoti seems distinct enough to consider them as different species. This raises the question, whether the assignment of G. benedeni to Microxina is legitimate. The great similarity between the species’ characters, as pointed out by Burton (1932), might speak for a close relationship between these species, thus justifying the assignment to Microxina, although on the other hand the species fits quite well with the definition of Gelliodes as given by Desqueyroux-Faúndez and Valentine (2002). A solution to this question can only be found through a close look at the holotype. Still, it must be mentioned that if this species is to be assigned to Microxina, the definition of this genus, as given in Desqueyroux-Faúndez and Valentine (2002), has to be emended in the way that not only microxea, but also sigmas are present in Microxina.
