Guyalna dyticamazona Sanborn, 2020b new record

Guyalna dyticamazona Sanborn 2020b: 35 . (Explorama Lodge, 50 mi. NE Iquitos on Amazon R., Loreto Dept., Peru)

REMARKS.—The species is similar in general appearance to G. brisa ( Walker, 1850) but has significantly different genitalia, opercula and timbal cover. The hyaline wings, body length between 24.90–29.75 mm, and piceous abdominal markings forming an arch on the dorsal surface distinguish it from all other species of the genus. The dark coloration, piceous markings on the thorax, and lack of apically bronzed fore wings quickly distinguish it from the other Ecuadorian species to have the piceous arches on the dorsal abdomen, G. distanti .

DISTRIBUTION.—The species is known from western Amazonian regions being collected in several localities within Loreto Province, Peru, Amazonas Province, Colombia and the State of Amazonas, Brazil. This record is from the Ecuadorian Amazon region.
