Proarna capistrata Distant, 1885 , rev. stat.

Proarna capistrata Distant 1885: 60 (type material examined).

Type locality. Buenos Aires, Argentina.

Remarks. Torres (1961) considered the species a junior synonym of P. montevidensis Berg. Torres’ specimens came from an area where the two species are sympatric and he considered the two species to be one ( Torres 1961b). When compared to P. montevidensis , P. capistrata is smaller, has less infuscation in the forewing, has less dorsal coloration, proportionately smaller forewings, the anterior point of the timbal cover is angled dorsally rather than pointing anteriorly, male opercula are angulate medially rather than rounded, the posterior cruciform elevation is smoothly rounded rather than angulate, and the primary femoral spine is more upright, the secondary spine is narrower at the base and the distal spine is almost missing in P. capistrata . More importantly, the male genitalia differ in the size and shape of the lateral uncal lobes ( Figure 16 ) and the medial unus lobes recurve dorsally at the posterior terminus in P. capistrata rather than forming a right angle. The species is known only from Buenos Aires Province, Argentina ( Distant 1885).
