ABSTRACT
Insect troglobite diversity is greatest in the beetles. Several staphylinids occur in caves, with the troglophile genus Quedius being the most frequently encountered. Spider beetles (Ptinidae) include some troglobitic species (e.g. Niptus), and the mold beetle family Pselaphidae is rich in troglobites, especially in the widespread genus Batrisodes, but also several other genera. Mold beetles occur in many caves of the Appalachians, Interior Low
