Vacerra molla E. Bell, 1959 is a synonym of Paratrytone barroni Evans, 1955

This species is known only from one female of Paratrytone barroni Evans, 1955 and one male of Vacerra molla E. Bell, 1959, both from Ecuador, which have similar distinct wing patterns. In particular, like in no other Hesperiidae, the hindwing below has a single cream band from mid-costa to the outer margin at cell CuA 2 -1A+2A, continuing as white fringes, and partly seen on the dorsal surface as a straight streak of spots. Therefore, V. molla is designated a junior subjective synonym of Paratrytone barroni Evans, 1955 .
