Reductodrilus can be distinguished from all other genera of Ototretinae sensu Janisova and Bocakova (2013) by the following combination of characters: antennae strongly serrate to weakly pectinate; maxillary and labial palpi digitiform, simple, with terminal palpomeres not distinctly enlarged; posterior pronotal angles without a circular pit; elytra lack sutural coadaptation, each elytron dehiscent distally, abdomen partially exposed; median lobe and parameres distinctly elongate; and phallobase relatively short and transverse. For comparative information on the morphology of other ototretine genera, see Janisova and Bocakova (2013). Composition and distribution. Four described species (one comprising two subspecies) are known from Borneo and the Philippines (see List of species below). Literature.
