Ochropleura Hubner

Type species: plecta Linnaeus, Palaearctic.

Synonyms 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.).

Typically 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 absent.

In 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.).
