Larvae of neotropical berosus (Coleoptera, Hydrophilidae): B. Aulus orchymont, 1941 and B. Auriceps boheman, 1859

Abstract

The larval stages of the Neotropical B. aulus Orchymont, 1941 and B. auriceps Boheman, 1859 are described and illustrated for the first time; comparative notes between first and third instar larvae, and information on their biology is included. Morphological characters to differentiate third instar larvae of B. aulus and B. auriceps from other known New World Berosus larvae are discussed.
