Atopsyche (Atopsyche) urumarca Schmid 1989

Atopsyche urumarca Schmid 1989 , 131 (Type locality: Brésil [ Brazil], Serra do Cipó, M.G. [Minas Gerais], Rio Capivara, 08.vii.1974, Luz, Froehlich, C.G. et al.; holotype depository: MZSP; male).

Atopsyche (Atopsyche) urumarca Schmid ; Paprocki et al. 2004, 7 (checklist); Santos & Holzenthal 2012, 75 (distribution; variation; male).

Diagnosis. This species belongs to the Atopsyche (Atopsyche) bolivari Group and resembles A. parauna in the small, arched second article of each inferior appendage. Distinctively, the parapods are each broad basally with a variably large or small oblique U-shaped incision at mid length of the dorsal margin in all specimens. The phallotheca is broadly rounded basally and with three paired processes posteriorly: two short, lateral, and one long, dorsal (“beaks”). Each “beak” bearing two small acute projections at the apex, which is truncate to shallowly excised and with the dorsal portion extended in a curved hook ( Schmid 1989; Santos & Holzenthal 2012).

Description. Overall body color yellow to brown (in alcohol). Setae of head and thorax elongate, erect light and dark brown; antennal scapes brown with long dark brown setae, pedicels and basal flagellomeres yellow and apical flagellomeres light brown. Maxillary and labial palps brown with long light and dark brown setae. Legs yellow to light brown. Forewing light brown with anterior and anal region dark brown, covered by short light and dark brown setae.

Remarks. In the genitalia, variation has been observed among populations in southeastern Brazil, especially in the shapes of the parapods and the beaks of the phallotheca ( Santos & Holzenthal 2012).
