Material studied. Type material. Holotype ♂ labelled: Type [rounded with red margin]; Genital praeparat nr. C. 5.9.86 /ETO sex: ♂ E. Traugott-Olsen; Wing praeparat nr. B. 25.3.87 /ETO; Austria inf. Pfaffenberg, Porta hungarica, 18.V.1969 leg. F. Kasy; Elachista grandella sp. n. det. Traugott-Olsen ( NHMW). Other material. Hungary: Nyir p. Kecskemet, 17–27. V.1937, 1 ♂, J. Klimesch leg., L. Kaila prep. 5839 ( ZSM).

Diagnosis. E. grandella is characterized by its large size with broad wings, as well as the broad valvae. Its phallus is shorter than that of E. dispunctella , and similar to that of E. dalmatiensis . E. grandella and E. dalmatiensis , if separate, are distinguished by their size difference (wingspan 11–12 mm and 7–8 mm, respectively) and the width of the valva. Due to the paucity of specimens known, however, the level of variation is not known. The female is unknown.

Biology. Specimens have been collected in xerothermic habitats.

Distribution. Austria, Hungary.

Remarks. The record of E. grandella from Germany ( Biesenbaum 1995) is here interpreted to represent E. dispunctella , as the phallus/valva length ratio in the genital illustration of the German specimen matches E. dispunctella , not E. grandella .
