Abstract
A new genus and species of cimicoid true bug,Ecpaglocoris ditomeusYamada & Yamamoto,gen. et sp. nov., is described and illustrated from mid-Cretaceous (Cenomanian–Albian) amber in the Kachin State of northern Myanmar (Burma). This new fossil genus and species is reminiscent of members of Anthocoridae by the strongly flattened and elongated body, four-segmented labium, distinct costal fracture and presence of fossula spongiosa on fore tibiae, but should not be ascribed to this family. The new taxon cannot be placed in any extant cimicoid families, based upon hemelytral, male genital and other morphological structures. Based on the hemelytral membrane venation and presence of dorsal laterotergites on abdominal segments I to VIII, it can be assumed that this new genus belongs to the extinct family Vetanthocoridae.Ecpaglocoris ditomeusgen. et sp. nov.has aberrant male genitalia characterised by sickle-shaped left and right parameres and grooves running throughout the paramere. This characteristic indicates that traumatic insemination occurred in this genus. The peculiar combination of male genital characteristics seen inEcpaglocorisgen. nov.prevents its placement in any of the extant cimicoid families.
