[8.iii.1962] Loc. 123 / Dry meadow / Lund University Ceylon Expedition 1962 Brinck-Andersson-Cederholm / HOLOTYPE Euscelidia prolata sp. nov. det. T. Dikow 2001 (red label)’. The specimen is double mounted (minuten in block of foam), is in poor condition (antennae, abdomen, and most of the legs broken, abdomen attached to foam block; ơ terminalia attached to specimens pin in micro vial), and is deposited in the MZLU.
Two ^^ paratypes have same labels as holotype except ‘ PARATYPE Euscelidia prolata sp. nov. det. T. Dikow 2001 (yellow label)’ are double mounted (minuten in block of foam), are in good to very good condition (one specimen with meso and meta legs broken), and are deposited in the MZLU .
