Apamea Ochsenheimer

Type species: basilinea Denis & Schiffermuller ( = sordens Hufnagel), Europe.

Synonyms: Abromias Bilberg (type species monoglypha Hufnagel, Europe), Septis Hubner (type species Lithoxylaea Denis & Schiffermuller, Europe); Xylophasia Stephens (type species polyodon Clerck sensu Linnaeus = monoglypha); Hama Stephens (type species basilinea); Crymodes Guenee (type species groenlandica Duponchel); Agroperina Hampson (type species lateritia Hufnagel, Europe); Syma Stephens (praeocc; type species hirticornis Haworth, Europe); Agrostobia (praeocc; type species sinuata Moore), Eleemosia Prout (type species abjecta Hubner = oblonga Haworth, Europe); Eurabila Butler (type species lignea Butler, India); Heteromma Warren (type species alpigena Boisduval; replaced by Heterommiola Strand).

This 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.

In 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.

Palaearctic species are predominantly grass feeders as larvae, a possible explanation for the form of ovipositor lobes.

There is one rare montane species in Borneo.
