The material came from expeditions and collections spanning 1959 to 2012. It included specimens collected by E. M. Hering in 1959, Peter Angenstein from 1978 to 1983, and Hermann Hacker and Hans-Peter Schreier during expeditions in 2006, 2008 and 2010. Additional tineids had been collected around Lake Tana during a 1996 Museum für Naturkunde expedition.

Most of the Hacker and Schreier material was collected as incidental bycatch in automatic light traps during expeditions primarily focused on macromoths. The moths were later sorted from the remaining material, and specimens in the Tineidae were selected for examination. Other unidentified Ethiopian tineids were drawn from the museum’s collection.

The researchers examined specimens with a Leica MZ 12.5 dissecting microscope, measured body parts using an ocular grid and prepared male genitalia in alcohol before embedding them in Euparal on slides. They also produced photographs, line drawings and a dichotomous key to African tineid families. The key requires study of male genitalia because external family characters are highly diverse and variable.

The new species were placed in four subfamilies: Hapsiferinae, Myrmecozelinae, Perissomasticinae and Hieroxestinae. Type localities included the vicinity of Lake Tana, Awash National Park, Lake Langano, Arba Minch, the Bale Mountains, Aluweya, Agere Maryam, the boundary of Mago National Park and Addis Ababa. The descriptions distinguished taxa through adult morphology and, in most cases, male genitalia.

The study also documented named species not previously reported from Ethiopia. These included representatives of Hapsifera, Criticonoma, Phthoropoea, Monopis, Tinea, Xerantica and Wegneria. A specimen was also tentatively associated with Perissomastix pantsa, although slight differences in its male genitalia made the identification provisional.

Holotypes and paratypes of the newly described species were deposited in the Lepidoptera collection of the Museum für Naturkunde, Berlin. The article also presented adult and genitalia illustrations and recorded collecting localities with coordinates and elevations, allowing the examined material to be associated with specific sites.

Several limitations affected the work. Much of the bycatch was in varying or poor condition and was difficult to prepare. Some identifications depended on older descriptions with inadequate illustrations, while a 2019 checklist of 20 Ethiopian tineid species omitted records published earlier. The authors described this discrepancy as evidence of limited faunistic research in Ethiopia, rather than a formal estimate of population trends.

Tineidae occupy varied feeding niches, with larvae recorded from materials including game horns and antlers, bird feathers and nests, and carnivore faeces. Some species can also attack clothing and food products. The study itself was a taxonomic examination of preserved moth specimens and did not assess those potential effects.
