The genus Elasmostethus is recognized by the combination of the following characters: body ovoid; ground colour of dorsum green (frequently faded to yellow in preserved specimens), usually with red markings, with dense and dark punctation; mandibular plates not exceeding apex of clypeus; antennae 5-segmented, with distipedicellite 1– 1.5 times as long as basipedicellite; labium not exceeding hind coxae; lateral margin of pronotum narrowly explanate; humerus rounded or angulate, slightly surpassing costal margin of fore wing in rest, never produced into a long process; mesosternal carina surpassing fore coxae (sometimes even base of head) anteriorly and mid coxae (sometimes even hind coxae) posteriorly; metasternal scent gland peritreme occupying two-thirds to three-fourths the width of metapleuron; Pendergrast’s organs present on abdominal ventrites VI–VII of females; pygophore of male simple, without notable projections or processes laterally, but frequently with paired hair tufts; paramere simple, usually somewhat broadened distally.
