A REVIEW OF RICHARDSITAS BETSCH AND TEMERITAS RICHARDS (COLLEMBOLA, SMINTHURIDAE)
Chaetotaxy, Sminthuridae, Sminthuroidea, taxonomy, Temeritas-group.
The Sminthurinae holds 18 genera, including extinct and extant genera. Among them, Richardsitas Betsch, Temeritas Richards, Galeriella Curcic & Lucic and Keratosminthurus Zeppelini are remarkably similar to each other especially due to their long antennae (antenna IV with 18 or more subsegments), metatrochanteral spine present and a similar ventro-dental chaetotaxy. But between these genera, Temeritas and Richardsitas possibly are the most similar and close related to each other. Due to this similarity, we performed a bibliographic review of Richardsitas and Temeritas in order to better circumscribe their genera and species diagnoses. We also present a description of a new species of Richardsitas (R. subferoleum sp nov. from Australia), a table and a comparative key for the Sminthurinae genera, tables and comparative keys for the species of Temeritas and Richardsitas as well as an updated diagnoses for both genera.
