A single adult of an unidentified hygromiid was discovered at a brownfield site on the margins of a carpark near Tilbury, south Essex, on 3rd May 2017. This was tentatively identified from photographs as a species of Monacha, possibly M. ocellata (Roth, 1839). Later in 2017, with the more widespread appearance of adults at the locality, a more detailed study was undertaken. This established, from the dissection of genitalia in sexually mature adults, that the species was indeed Monacha ocellata, native to the south-east Mediterranean and unknown in northern Europe. Molecular analysis (nucleotide sequencing of mitochondrial COI and 16SrDNA as well as nuclear ITS2 gene fragments) showed a close relationship to GenBank sequences for Monacha ocellata originating from the Citadel of Constantinople, Istanbul.
