Palumbina guerinii : Sattler 1982

The guerinii -group

Diagnostic characters. This group is defined by having forewing ground color grey to fuscous, and having a dirtywhite or yellow antemedian fascia and two or three distal streaks. The male genitalia are characterized by the small and tongue-shaped uncus (approximately 1/4 length and 1/4̄1/3 width of tegumen), the short gnathos, the slender valva with well-developed sacculus. In addition, the aedeagus is generally short and stout, and bears a sclerite exceeding apex. The female genitalia are characterized by the posteriorly narrowed tergum VIII, the broad collarlike colliculum and the signum with a hook- or thumb-shaped process.

Remarks. This species group is named after the type species P. guerinii (Fig. 65). The members of the group show low genetic divergence compared to other groups and they are also highly similar to each other morphologically.
