Suborder:Glossata Infraorder:Heteroneura Superfamily:Yponomeutoidea
Considered as Subfamily: Argyresthiinae of Family Yponomeutidae in MBGBI3
Argyresthia (24S)
Head down resting posture; Head with vertex rough, frons smooth, Ocelli absent. Proboscis developed, unscaled
Antenna 3/5 - 4/5 length of forewing; smooth to serrate; slightly or moderately pubescent; scape with pecten
Labial palp moderate, somewhat curved, porrect or obliquely ascending, smooth or somewhat rough ventrally; S3=/>S2; S3 pointed
Maxillary palps 1-segmented, minute
Forewing lanceolate, with 12 veins (or 11 if V4&3 coincident); Hindwing narrower than forewing, lanceolate or linear-lanceolate, with 8 veins
Small Y- or V- shaped plate on abdominal S8 in male (I need to determine exactly where this is as MBGBI3 is confusing and gives apparently conflicting information. In the key to subfamilies it does not specify; the introduction to Argyresthiinae states "loosely attached to the 8th abdominal sternite" and in the description of genus Argyresthia "on the dorsal side" of abdominal segment 8).
Male genitalia: uncus poorly developed; socius expanded to form a large lobe; valva simple; saccus absent; aedeagus longer than valva, cornuti present. MBGBI3 also mentions "distinct pseudovalva as in Yponomeutinae" but does not illustrate this in its genital drawings of Argyresthia and does not even mention it in its descriptions of Yponomeutinae. Coremata usually present
Female genitalia: antrum defined, membranous, funnel-shaped; ductus bursae long, membranous; corpus bursae with signum with 1 or 2 strong processes
