is a primarily Holarctic genus, with a typical trifine forewing facies.
Diagnostic features may be found in the male genitalia: the peniculus of the
tegumen is enlarged, usually squarish; the valve has a strong cucullus and
corona, the neck of the cucullus being distinctively angled ventrad; the trifine
process from the valve costa is long and passes more or less over the ventral
angle of the cucullus neck flexure, well distal to the slender harpe; the setae
on the interior lamina of the cucullus are restricted to a narrow ventral zone.
The aedeagus vesica tends to be short, with only a few isolated, short cornuti.
Trifine hair-pencils are present. The eighth sternite in the male has a very
small corematous pocket subbasally.
the female genitalia (sodalis) the bursa is simple, pyriform, slightly
corrugate, without signa; the ductus is moderate, slender, scobinate over the
basal third; the ovipositor lobes are tapering, forming a slender cone that is setose in a manner approximating to that of the Holarctic graminaceous stem
borers discussed below.
species are predominantly grass feeders as larvae, a possible explanation for
the form of ovipositor lobes.
