Discriminating Anillinus and Serranillus

Anillinus is broadly sympatric with Serranillus . Previous keys have relied on male characters for distinguishing these two genera (e.g., Ball and Bousquet 2001). We offer the following set of characters to facilitate discrimination of the two genera.

Elytral discal primary setae not reduced in Elytral discal primary setae greatly reduced length, same size as basal in length, at most one-half length of (scutellar) setae basal (scutellar) setae

Vestiture of elytra less than one-third length Vestiture of elytra more than one-third

of discal primary setae length of discal primary setae. Microsculpture of head and pronotum Microsculpture absent from head and various. pronotum (except small triangle at middle of vertex).

Sternum VII in males with Sternum VII in males with apical margin entire apical margin. bearing three denticles.
