Urophorus
Urophorus is a genus of sap-feeding beetles in the family Nitidulidae, containing at least two described species. The genus is characterized by association with fermenting plant material and fruit. Urophorus humeralis, commonly known as the pineapple beetle, has been documented as a pest of pear fruits in Chinese orchards. The genus is distinguished from related nitidulids by morphological features, though specific diagnostic traits require detailed examination.
