On the presence of a stridulatory apparatus in leaf beetles of the subfamily Eumolpinae (Coleoptera, Chrysomelidae)
TLDR
Stridulation has been observed for the first time in a representative of the subfamily Eumolpinae, Bromius obscurus Linnaeus, and is located on the upper side of each wing in the form of a dark convex spot with complicated microsculpture between RS and Cu veins.
A Review of the Genus Cryptolaemus Mulsant (Coleoptera: Coccinellidae: Coccinellinae: Coccidulini) from New Guinea
TLDR
Thirty-two new species of Cryptolaemus Mulsant endemic to New Guinea / Australasia are reviewed and four more species groups are tentatively recognized based on male genitalia and other characters: iodes-group, magnificus- group, riedeli-group), and bicolor-group; some of the species are unassociated with any of these groups.
Form, function and evolutionary significance of stridulatory organs in ant nest beetles (coleoptera: carabidae: Paussini)
TLDR
The independent evolution of three types of stridula ­ tory organs in three lineages of Paussini suggests that acoustical communication has played an important role in the evolution of ant nest beetles.

Stridulation and defensive behaviour in the ground beetle, Cychrus caraboides (L.)
TLDR
Adults of both sexes of C.caraboides stridulate by means of an elytroabdominal mechanism that covers a wide band of frequencies from audible to about 80 kHz and it is suggested that stridulation may act as an acoustic warning to certain vertebrate predators.
