As Sceliphron bilineatum Maxwell-Lefroy, 1909: 207 (described from Western India, but occurring also in other parts of India; nest).

Sceliphron pulchellum Gussakovskij, 1933: 275, ♂. Holotype: ♀, Iran: Bushire, now Bushehr (ZIN). As Sceliphron rectum pulchellum: Hensen, 1987: 226 (new status).

Diagnosis. Female. Clypeus apico-medially incised, without lateral incisions (see Fig. 12 of Hensen (1987: 223); metanotum with broad yellow band; propodeum with yellow basal spots and very large terminal yellow mark confluent with pair of spots in dorsal enclosure; legs yellow except basal third of femora and hind tibia black; first tergum with large yellow markings; petiole in lateral view nearly straight.

Male. Similar to female except additional yellow spot on all coxae; first tergum nearly entirely yellow, third to seventh terga with yellow apical bands. Hensen (1987) notes that the third and fourth terga are black in specimens from India and Pakistan.

Note: No specimens were seen during the present study, so the above diagnosis has been based on the description by Hensen (1987).

Distribution. India: Bihar, Gujarat. Elsewhere: Iran; Iraq; Oman; Pakistan; Russia; United Arab Emirates (Hensen, 1987; Gadallah, 2020; Pulawski, 2021).
