35.087 Neofriseria peliella (White-spot Groundling)
ws: 13-16mm (MBGBI4.2); Jul; sheep's sorrel (Rumex acetosella); RDB mainly on coastal shingle in Kent
Neofriseria peliella §6 male
|
ID: Forewing blackish fuscous; black spots - small costal at base, central subbasal, 2 antemedian (discal distal to plical) edged distally with whitish scales, postmedian discal edged with whitish scales; whitish spots preapical and at tornus which may be extended to form an incomplete subterminal fascia. N.singula has the antemedian spots level with each other and has a paler greyish-fuscous forewing. 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 process > Neofriseria. Both species are illustrated in MBGBI4.2 (figs 10h&i) and both are shown at Moth Dissection. Following personal correspondence with Peter Hall a comparative image is now available at MD which suggests the following 2 means of distinction: 1) Both species have an area of short stud-like hairs at the apex of the uncus surrounded by longer hairs on either side - in N.singula the area of short hairs is larger than in N.peliella. 2) In N.peliella the gnathos is evenly curved; in N.peliella it is more angular. However, note that my N.peliella §4 has the discal spot distinctly distal to the plical but shows the genital features of N.singula. Female genitalia: Both species are illustrated in MBGBI4.2 (figs 32c&d), only N.peliella is shown at Moth Dissection. I difference is illustrated in the form of the signum, but I am not sure whether this is a valid discriminator between the species. |
