Elachista bidentata Varenne & Nel, 2019

Elachista bidentata Varenne & Nel 2019: 89 , figs. 17–19.

Examined material. Holotype Ƌ: France, Isère , Auris-en-Oisans, 1700 m, 7.VI.2018, Th. Varenne leg., genitalia slide TV n°6724 ( RCTV).

BOLD Specimen ID TLMF 27072; BOLD Sequence ID LEASV320-19.

BIN: not barcode compliant, but clusters with BOLD:AAP5716

Identity: Elachista orstadii Palm, 1943 , syn. nov. ( Fig. 9 )

Remarks. Elachista bidentata was described from a male holotype and separated from E. orstadii on subtle differences in genitalia (Varenne & Nel 2019). However, the DNA barcode sequence of the holotype fully corresponds with the latter species and the alleged genitalia differences are within the intraspecific variation of large samples from Europe and Siberia (Kaila in litt.). We therefore synonymize E. bidentata with E. orstadii .
