Atopsyche (Atopsyche) erigia Ross 1947

Atopsyche erigia Ross 1947 , 129 (Type locality: Mexico, Edo. Tamaulipas, Hacienda Santa Engracia, 09.iii.1939; holotype depository: INHS; male); Edwards & Arnold 1961, 401 (larva; distribution); Bueno-Soria & Flint 1980, 191 (distribution).

Diagnosis. This species belongs to the Atopsyche (Atopsyche) tripunctata Group and is recognized by the parapods each having a short subapicodorsal tooth and another short apicodorsal tooth; the filipods being longer than the parapods; the first article of each inferior appendage being straight, parallel-sided and simple; and the phallotheca being broad and sinuate, truncate apically ( Ross 1947). This species is most similar to A. chirihuana in having parapods each with two short dorsal teeth, a simple phallotheca, and a subtriangular second article of each inferior appendage; however, in A. erigia the second article is rounded apically, not truncate as for A. chirihuana .

Description. Overall body color yellowish to dark brown. Antennal scapes with light brown and white setae, pedicels and basal flagellomeres yellow, apical flagellomeres brown. Maxillary and labial palps with light brown and yellow setae. Setae of head and thorax elongate, erect, whitish with few darker setae. Postero- and mesolateral elongate setae in all abdominal terga. Legs yellowish to dark brown. Forewings light brown with yellowish setae at midlength, apices with fringes of alternating patches of brown and and yellowish setae; posterolateral glands on tergum II. Genitalia, with long slender filipods bearing scattering of long setae at apices, parapods upcurved and each bearing dorsal indentation and then tooth some distance before apex, inferior appendages long and slender, each with first article more than twice as long as wide; second article evenly tapering and rounded at apex, little more than one-half as long as first article; phallic apparatus broad and sinuate, truncate at apex, aedeagus upturned and curved ( Ross 1947).
