The genus Platyscelio Kieffer (Hymenoptera: Platygastridae, Scelioninae) is a widespread group in the Old World, found from West Africa to northern Queensland, Australis..

The genus is comprised of 6 species, including 2 known species which are redescribed: P africanus Risbec (Benin, Cameroon, Central African Republic, Ghana, Guinea, Guinea-Bissau, Ivory, Coast, Kenya, Mozambique, Nigeria, Sierra Leone, South Africa, Tanzania, Togo, Uganda, Yemen, Zimbabwe); and P. pulchricornis Kieffer (Australia, Bangladesh, China, India, Indonesia, Japan, Malaysia, Papua New Guinea, Philippines, Solomon Islands, Taiwan, Thailand, Vanuatu, Vietnam). Five species-group names are considered to be junior synonyms of P. pulchricornis: P. abnormis Crawford syn. n., P. dunensis Mukerjee syn. n. P. mirabilis Dodd syn. n., P. punctatus Kieffer syn. n. and P. wilcoxi Full sway. The following species are hypothesized and described as new taxa: P. arcuatus Taekul
