Mesene monostigma monostigma  (Erichson, [1849])

( Figs 3–4View FIGURES 1 – 32, 34View FIGURES 33 – 40)

Two males of this taxon were collected on the same hilltop, one in 2011 and another in 2014. In both years the males were observed following typical hilltopping behavior consisting of erratic flight, about four meters above the ground around 13:00h.

Specimens collected at the PNSD were tentatively identified as M. monostigma monostigma  , even though the PNSD is closer to the type locality of M. monostigma discolor Stichel, 1929  . This taxon was recognized by Hall & Harvey (2002) as a subspecies of M. monostigma  due to intermediate specimens between these two phenotypes in eastern Andes   . Nevertheless, Mesene discolor Stichel, 1929  was described based on a female specimen from Bolivia, and no males were yet associated with certainty to this female. The male illustrated by D’Abrera (1994, p. 1027) and identified as M. monostigma discolor  supposedly from “ Bolivia?”, is similar to the specimens collected at the PNSD, except by the presence of an additional white spot in CuA2–2A submarginal area of the forewing upper side. However, it is inadvisable to recognize this specimen as the male of M. monostigma discolor  , due to the vagueness of the collecting locality and the lack of knowledge on the intraspecific variation and extent of the distribution of M. monostigma monostigma  . 

A large series of M. monostigma  studied by us reveals the existence of at least two species with similar phenotype in this complex, based on the morphology of the male genitalia (Dolibaina & Dias, pers. obs.). Nevertheless, specimens collected at the PNSD are similar in the morphology of male genitalia to specimens of M. monostigma  from southern Brazil, Paraguay and Argentina, which are usually identified as M. monostigma monostigma  (e.g. Salik et al. 2014). Given the distinctive morphology of the male genitalia, the phylogenetic affinities of M. monostigma  are still uncertain.
