Tribe Obscurini Fibiger , new tribe

Type genus: Obscura , new genus.

Taxonomic notes. The tribe Obscurini , new tribe, includes eight new genera, Abes , Asyprocessa , Tantulius , Asylemissa , Clarior , Obscura , Editum , and Asytegumen , altogether with 15 new species. The descriptions below reflect the phylogenetic sequence of the taxa in Obscurini . It is possible to identify an Obscurini specimen as a member of Micronoctuidae , but generally it is difficult by external characters to recognise it as belonging to Obscurini ; only a careful examination of the genitalia can place a specimen in the tribe.

Diagnosis. Character states of tribe Obscurini with synapomorphies indicated by (apo.) described in detail under family Micronoctuidae , subfamily Tactusinae , and briefly under genera below, avoiding most repetitions from higher taxa. Most important characters for tribe are:

- on average smaller size;

- apically rounded shape of ampulla (apo.);

- anterior edge of valva and ampulla T-shaped (apo.);

- digitus absent (apo.).

Differential diagnosis. Species of Obscurini differ from those of Tactusini in several character states, e.g., on average smaller species; apically rounded shape of ampulla plate; absence of digitus; usually with shorter phallus; and usually with shorter antrum. Distribution. Tropical, subtropical, and temperate areas of Oriental Region.
