brasiliensis group

Description. Antenna weakly clavate (Fig. 36) (unknown in N. brasiliensis); posterior fork of CuP+1A ending at hindwing margin beyond level of radial sector which originates well distad of cubital fork; wings marked (except N. amazonas); midlegs and hindlegs as long or longer than forelegs, setae opposing pretarsal claws on forelegs not hooked (Fig. 29); midleg not swollen; midleg tarsomeres 1-4 not flattened ventrally; foreleg tarsomeres 2 and 3 (Fig. 28) less than one-half length of distal tarsomere; female gonapophysis without gonapophysis-like process extending from lateral margin of lateral gonapophysis; posterior gonapophysis greatly expanded (Fig. 55).

Discussion. The three species comprising this group have the foreleg no longer than the hindleg and the ventral setae on the distal tarsomere are not hooked apically. Also, two species have dark spots on the forewing. The female posterior gonapophysis are greatly expanded. The highly modified male genitalia of N. amazonas are unique in the genus. The discovery of larvae and genome analysis of the species may remove this group from Navasoleon .
