بررسی گونه‌های جنسDiomus Mulsant, 1850 (Coleoptera: Coccinellidae) در منطقه خاورمیانه

The genus Diomus Mulsant, 1850 belongs to the tribe Diomini Gordon, 1999 was originally described by Mulsant (1850) as a subgenus of Scymnus Kugellan, 1794, after that elevated to generic level by Weise (1895), that comprises around 400 described species in the world. Due to the rarity of these species in the Middle East and the role of these species in the natural control of pests, it is a necessary implementation of these studies in order to preserve of the biodiversity these species and introduce these species as biological control agents. This study was provided based on collected samples and a review of reliable and published sources. The samples were collected in Kermanshah city, Kermanshah province. We updated the species of Diomus Mulsant, 1850 in the Middle East region. The samples and male genitalia were studied by Stereo Microscope (Olympus SZ-ST) and microscope (Olympus CX21) respectively, and images were taken by an iPhone 8 plus camera and edited in Photoshop software (Adobe Photoshop CS5.1). Field Emission Scanning Electron Microscope was used to investigate the detailed morphological characters and to provide illustrations. Drawings have been done by CorelDRAW Graphics Suite 12.0 software. The Adult species has been drawn by Mehid Romasi. we removed the species of D. rubidus (Motschulsky, 1837) and D. anemicus Fürsch, 1960 from the fauna of Turkish and Palestine ladybirds, respectively. We could not confirm the present of D. anemicus in the Middle East. Also, our studies have shown D. rubidus is not common species in the Middle East. We provided more details of morphological features with the help of an electron microscope and the differential characters of this genus in comparison with other close genera are presented.
