Seven species are known in the Eastern Palaearctic ( Tang et al . 2016b ). Both generations are known for most species, the majority of which are associated only with evergreen oaks. Adults resemble those of Chilaspis . Three species are known from Israel on Q. calliprinos , one of which has been found only once.
