The Meloidae, known as blister beetles, a widespread family of Tenebrionoidea that includes approximately 2500 species, is still scarcely known faunistically in several areas of the world. Because of specific biogeographical feature, Iran harbors a rich diversity of meloids and due to the lack of basic and integrated studies, particularly in eastern parts of Iran, our current knowledge of Iranian meloids should be considered preliminary. In order to improve the knowledge of the meloidae species of north eastern Iran, faunistic investigations on blister beetles of this region were carried out during 2011-2012. Collected specimens as well as deposited specimens in Insect Museum of Ferdowsi University of Mashhad were examined, in detail. As a result, 31 species belonging to 11 genera from 2 subfamilies were identified. Among the identified specimens, 24 species were new for fauna of Khorasan provinces. Ctenopus sinuatipennis Fairmaire (1892) is reported for the first time from Iran.

The family Meloidae Gyllenhaal‎, 1810 (Coleoptera), commonly known as blister beetles, exist in warm, dry, and vast habitats. This family was studied in Kerman province of Iran during 2018–2019. The specimens were collected using sweeping net and via hand-catch. They were identified by the morphological characters, genitalia, and acceptable identification keys. To improve the knowledge of the Meloidae species of southeastern Iran, faunistic investigations on blister beetles of this region were carried out. Totally, 30 species belonging to 10 genera from two subfamilies (Meloinae and Nemognathinae) were identified. Among the identified specimens, 22 species were new for fauna of Kerman province.
