Niptus
spider beetles
Niptus is a genus of spider beetles (Coleoptera: Ptinidae) distributed across the Australian region, Palearctic (including Europe), Near East, Nearctic, and North Africa. The genus as currently circumscribed is polyphyletic; North American species have been transferred to the new genus Coleotestudus based on morphological and molecular evidence. The type species Niptus hololeucus (golden spider beetle) represents a distinct clade not closely related to the former North American members.
