35.117 Scrobipalpa atriplicella (Mottled Orache Miner)
ws:13-15mm; May-Sep; orache (Atriplex spp), goosefoot (Chenopodium spp); common on waste ground in England
Scrobipalpa atriplicella §1 male
ID: As with other Scrobipalpa species, requires genital examination for confident identification
Male genitalia: coremata absent; posterior margin of uncus truncate or concave; valvae exceeding uncus
Female genitalia: the only Scrobipalpa species with the signum on the left (both anatomically and in the standard view with ventral surface up and posterior at top). The key in MBGBI4.2 makes harder work of it and keys it thus: CB clearly defined; signum in transition zone between DB and CB; CB spherical; posterior apohphyses at least as long as DB; ventral zone free from honeycomb pattern; signum on left, concave side mostly smooth.
