Identification
Distinguished from other Sminthuridae by antennal structure and body chaetotaxy. N. clavatus, originally described as Sminthurus clavatus by Banks in 1897, can be recognized by its (club-shaped) . N. bakeri and N. richardsi, both described by Snider in 1978, require examination of specific setal arrangements and antennal proportions for identification. Close examination of the mucro and dens of the furcula may aid in -level identification.
Appearance

Distribution
Central and North America. GBIF records suggest presence in Amazon, Caribbean mainland, and North American regions, though some records (S.E. Asia, E. African Steppe) may represent data quality issues or misidentifications.
