Propsti Group

The Propsti Group contains a single species, the Santa Catalina Island endemic (Fig. 8) N. propsti . The Group is defined by having a single spine on the fore tibia located on the posterior margin, a pair of prosternal spines, darkened male tegminal apices, and a female subgenital plate that is over half again as long as wide. Only N. lucubrata from mainland California shares this suite of characters, but this species has a smaller body size, a male subgenital plate that narrows from base to apex along the lateral carinae, and a song that consists of a bout (chirp) structure (Plate 5C) whereas the song of N. propsti is continuous (Plate 4J). The karyotype is unique.
