Etymology. The Buddha was religious leader who lived in ancient India and founder of the world religion of Buddhism, which is widely practiced on the Indian subcontinent. The specific epithet buddha is a noun in apposition.

Remarks. This species was wrongly identified by Børge Petersen as Trogaspidia acidalia ( Cameron, 1897) in the USNM collection. ASL found, among his series, some females that correspond to the original description ( Cameron 1897). Thanks to Gavin Broad (BMNH), ASL studied photos of the lectotype of Mutilla acidalia Cameron, 1897 ( Fig. 14 ) and found it to be identical to the female specimens examined herein. Therefore both sexes of Trogaspidia acidalia sensu Petersen are described here as Eotrogaspidia buddha sp. nov.
