species: plecta Linnaeus, Palaearctic.
and subgenera: Orbifrons Staudinger (type species singularis Staudinger,
South U.S.S.R.); Phleboeis Christoph (type species petersi Christoph,
South U.S.S.R.); Stenosomides Strand (type species synesia Turati,
N. Africa; replacement name for Stenosoma Turati, praeocc); Yigoga Nye
(type species signifera Denis & Schiffermuller, Europe, replacement
name for Ogygia Hubner, praeocc.).
this genus consists of Agrotis-like species (though Lafontaine (1987)
associated this genus in the Noctuini with Diarsia Hubner rather than in
Agrotini with Agrotis), usually with a broad, often pale, unmarked zone
along the forewing costa. The male genitalia have a central harpe as in Agrotis,
but lacking the dorsal accessory lobe and having an acute process at the
base of the ventral supporting sclerotisation of the harpe. A coronal fringe is
often present. The aedeagus vesica is very much shorter than in Agrotis, with
a diagnostic, massive, reversed cornutus; there are usually one or more lateral
lobes basally on the vesica. The male eighth sternite has a single corema just
within its anterior margin in the type species and its Oriental relatives. In
the female the appendix bursae is shorter than the bursa; signa are typically
the Indo-Australian tropics there flies a group related to the type species,
discussed below, and a much larger species, more distantly related, flies in
Seram and New Guinea (Ochropleura hasta Prout comb. n.).
