35.088 Neofriseria singula (Mottled Groundling)
ws: 13-15mm (MBGBI4.2) ; Jun-Jul; sheep's sorrel (Rumex acetosella); RDB heath and breck in SE England
Neofriseria singula §1 female (image provided by Daniel Blyton)
ID: Similar to N.pelliella and to Bryotropha species. Bryotropha species have a pecten on the antennal scape composed of a single seta, Neofriseria species do not have a pecten. N.singula has a paler fuscous ground colour than N.pelliella. Both Neofriseria species have several indistinct black forewing spots including an antemedian pair (discal and plical); in N.pelliella the discal spot is distal to the plical spot, in N.singula this pair are ~level. N.peliella is found mainly on coastal shingle in Kent, but the Gelechiid recording scheme lists several inland records; N.singula is found on (mainly inland) heath and breck.
Male genitalia: S8 divided into dorsal and ventral plates; gnathos simple; valvae flat with bristles, divided into 3 lobes with a long curved harpe > Neofriseria. Both species are illustrated in MBGBI4.2 (figs 10h&i) and both are shown at Moth Dissection - I have been unable to discern any consistent difference between the male genitalia of the two species and none are described in either reference.
Female genitalia: Both species are illustrated in MBGBI4.2 (figs 32c&d), only N.peliella is shown at Moth Dissection. A difference is illustrated in the form of the signum, but this does not seem to be a valid discriminator between the species.
