Nallachius ovalis Adams

Adams (1970) described this species from Nova Teutônia, state of Santa Catarina, Brazil. It was previously only known from the type series, which includes the holotype, and male and female paratypes. We examined a large series of Nallachius ovalis collected from the type locality. To our knowledge, this represents only the second collection of this species, the first being the type series. It is not clear why these additional specimens were not included in Adams (1970), although they were clearly collected about the same time as the type series. Machado and Rafael (2010) reported on a collection of Nallachius dicolor Adams , which also is known from Nova Teutônia, state of Santa Catarina, Brazil. These two species are closely related, and their genitalia are largely indistinguishable. They can be easily separated on the basis of their unique wing venation. The costal area of N. ovalis is wider than that of N. dicolor , and while N. ovalis has most of the distal costal veinlets forked, the veinlets are simple in N. dicolor . The three specimens from São Paulo, Brazil were in alcohol and slightly faded, and the genitalia would not completely clear. Nonetheless, the observable characters indicate this species is N. ovalis , and this locality represents a new state record for the species in Brazil.
