Diagnosis.

Very small to very large (1.0-22.8 mm); integument reddish brown (black in Acrostomus  ); vestiture consisting mostly of dense scales and setae (rarely only scales or setae), setae on rostrum and pronotum directed anteriad or mesad, on elytra posteriad; rostrum stout and very short to slender, as long as or longer than pronotum; scrobes usually lateral; epistome poorly demarcated, rarely raised ( Acrostomus  ); eyes usually large, flat, transverse or subcircular; mandibles with two apical cusps and paucisetose (1-4 setae); antennae with funicle 7-segmented, segments 1 and usually 2 elongate, clubs fusiform or inflated; prothorax with or without postocular lobes; prosternum long, non-excavate; elytra oblong-oval, elongate-oval or subrectangular; tibiae mucronate, generally with spurs (when present pro- and mesotibiae with 1 spur and metatibiae with 1-2 spurs); claws divaricate, simple or with slight basal swelling; aedeagus with tegmen lacking parameres (reduced in Methypora  ); distal gonocoxites membranous, generally simple, with large, apical or subapical stylus carrying a tuft of setae, but occasionally without stylus and apex of gonocoxite flattened and bent outwards.

Comparative notes.

Listroderini were formerly considered as related to Rhythirrinini  ( Kuschel 1971; Anderson and Morrone 1996; Morrone 1997a, b, 2002a; Anderson 2002). Oberprieler (2010, in press) considered Notiomimetini  to be close relatives of Listroderini  , although he suggested that more detailed studies would be required to decide whether they should be merged into a single tribe or not. Based on the results of this analysis, Listroderini  and Notiomimetini  (Aphela) are hypothesized to be sister tribes.

Biology.

Larvae of Listroderini  are generally oligophagous ectophytic root-feeders ( Oberprieler in press). Adults feed on the leaves of a variety of angiosperms ( Morrone 2011).
