The article highlights a study which examined a new species of the genus Cardiophorus Eschscholtz from Kalar Khar, Punjab Province, Pakistan. An ocular grid microscope was used to investigate the species' head, thorax, male genitalia and female genitalia. The species is called Cardiophorus kaharensis, derived from its locality. The species was found to be the smallest in all the Indian species. The species showed to be closely related to and appeared to form a close sister group to C. varius Cate.
