Description of adults: Original description by Curtis (1839): "Antennae alike in both sexes, remote, inserted on each side of the forehead towards the eyes, shorter than the body, filiform, hairy beneath, the basal joint large and subovate, 2nd globose, 3rd long and slender, the remainder turbinate (1).
Maxillae very small, short, terminating in an elongated curved lobe (3). Palpi much longer than the head, porrected, stout and 5-jointed, two basal joints long and nearly linear, 3rd a little longer and slightly curved, 4th very long, inflated towards the base, attenuated to the apex, 5th the shortest, the apex conical (a).
Labial palpi small, attached to large scapes, triarticulate, basal joint small, 2nd the longest and largest, obovate, 3rd much smaller, subovate (4).
Head rather broad, very short, crown hairy: eyes small and lateral. Thorax very short, clothed with depressed scales. Abdomen short, the apex of the males furnished with 2 long curved horny appendages with a large and dilated lobe above (A): conical in the female. Wings deflexed in repose, much longer than the body, ovate-lanceolate: superior (9) with many nervures terminating on the costa and interior margin: inferior with similar nervures on the margins (*): cilia long, especially the inferior, and surrounding the apex. Legs rather slender, hinder long: thighs short: anterior tibiae with an internal spine, the others spurred at the apex; hinder curved, with a pair also below the middle: tarsi 5-jointed, basal joint long, terminal short: claws small (8+ hind leg)."

Curtis (1839) compares his new genus with Lampronia Stephens, 1829, obviously in knowledge of the already described genus Micropterix Hübner 1825, which he assumes to be congeneric with Lampronia (pl. 639). Nevertheless, when transferring several Lampronia-species of the recently published plate 639 to Eriocephala (plate 751), he does not recognize the identity of Tinea podevinella Hübner, 1813, the type species of Micropterix, with the common British species Tinea seppella Fabricius, 1777, one of the species he transfers to Eriocephala. The following other taxa, Curtis (1839) also assumes to belong to Eriocephala (text to pl. 751: "A short notice of all the species will be found at fol. 639b, under Lampronia, from No. 10 subpurpurella to No. 20 bistrigella"): 10. subpurpurella Haw., 11. purpurella Haw., 12. auropurpurella Haw., 13. rubroaurella Haw., 14. rubrifasciella Haw., 15. sanguinella Haw., 16. calthella Linn., [17. omitted], 18. seppella Fab. ?, 19. ammanella [sic!] Hüb., 20. bistrigella Haw.. Curtis (1839) also is aware of the basal placement of Eriocephala within Lepidoptera, giving some characters that separate Trichoptera from Lepidoptera and placing Eriocephala definitely in Lepidoptera. The type species of Eriocephala, Phalaena (Tinea) calthella Linné, 1761, is a true Micropterix Hübner, 1825, although probably belonging to a basic group of that genus. Morphologically, it is somewhat isolated within the genus, but there is no need to separate it in a genus of its own.
