Coleophora ericarnella is smaller than C. pyrrhulipennella (Figs. 3–4) and C. pulchripennella (Figs. 5–6), especially the females. The coloration is overall paler, ochre instead of brown, more golden yellow, with the white streaks thinner and less prominent. In the male genitalia, the cucullus is shorter and thicker, the ventral edge of sacculus is more straight and almost without a protuberance at the ventral angle, which is distinct in C. pyrrhulipennella (Fig.15) and even more so in C. pulchripennella (Fig. 16); the cornuti are smaller and less numerous. In the female genitalia, the most distinctive feature is the spinulose section of the ductus bursae which is shorter than in C. pyrrhulipennella (Fig. 18), and very thin as opposed to being very thick in C. pulchripennella (Fig. 19). The signum of C. ericarnella (Fig. 20) has a more robust spine with a smaller, less expanded and unnotched base, whereas that of C. pyrrhulipennella (Fig. 21) has a wide base with a medial notch; in C. pulchripennella (Fig. 22), the signum base is evenly rounded and wider than in C. ericarnella. Description. ♂ (Fig. 1) Wingspan 12–14 mm. Head ochre, nearly white around eye. Labial palp white on inner side, brown on outer side; 3rd article about half length of 2nd. Antennal flagellum annulated with dark brown and white; scape brown with prominent tuft of long, erect, brown scales. Thorax white. Tegula ochre with some white on outer margin. Forewing ochre with dull white streaks: costal streak thin, gradually widening toward fringe; fringe white in proximal 1/3, brown distally; discal streak at dorsal edge of cell, widened medially and interrupted before termen; dorsal streak along fold; a thin white line bordering dorsal margin to terminal fringe; fringe pale brown. Hindwing brown with brown fringe. Abdomen greyish brown. ♀ (Figs. 2, 7) Wingspan 10–11.5 mm. Forewing paler than in male, pale streaks shiny white; pale costal streak wider distally and extended to costal fringe; medial white streak nearly straight, shorter and thinner than in male. Male genitalia (Figs. 8–10, 13–14): Spinose knob of gnathos rounded. Tegumen short, squat, with short pedunculi. Transtilla thin, elongate, oblique. Valvula large in proportion to sacculus, well delineated with rounded ventral edge. Cucullus narrowly elongate, slightly wider apically. Sacculus subrectangular, ventral edge slightly arched, lateral edge almost straight or slightly curved, with ventro-caudal angle rounded. Phallotheca tubular, distally narrowed, dorsal side more sclerotized. Cornuti about 20 in number, small and grouped into thin, somewhat inconspicuous band. Female genitalia (Figs 12, 17, 20): Papillae anales transversely broad, oval. Posterior apophysis about 3x longer than anterior one. Sterigma subtrapezoid in outline, wider than long, irregularly melanized; distal edge convex around ostium bursae and with elongate, stout spines. Ostium bursae cup-shaped, squarish. Colliculum shaped like very elongate funnel with sides more sclerotized than middle, with thin dark midline. Ductus bursae with distal (caudal) section almost transparent, with thick, dark midline and with short finely spinulose section just anterad of colliculum; middle section papillate around inception of ductus seminalis; anterior section to corpus bursae membranous. Corpus bursae rounded; signum large, thorn-like with strong, curved hook and relatively narrow base. Abdominal apodemes (Fig. 11): Latero-posterior strut about 2x longer than anterior strut. Transverse strut thick, distal edge more sclerotized. Spine patches of tergum 3 with 12–16 spines. Larval case (Figs. 24–26): similar to those of C. pyrrhulipennella and C. pulchripennella; made up entirely of lustrous black silk; 7–8 mm in length, elongate, subcylindrical with a slight curvature, laterally compressed, with the oral end narrower and oval at a 10–30˚ angle; anal end rounded with a bivalved opening; surface of case with obvious growth lines, and about the middle on the dorsal side is a small brown patch which is the remnant of the early case; the ventral side has a weakly developed keel. Biology. The larval host plant is Erica carnea L. (Ericaceae). The early larval instars have not been observed. However, it is likely that the life cycle is similar to that of C. pyrrhulipennella which is described in Emmet et al. (1996). Partly grown larvae were found (in Lavant, Osttirol) in the first half of May mining new terminal leaves of the host plant. At the end of larval growth, the final case is attached on a twig in a sun-exposed location, with the anal end turned upward. The flight period occurs between June 20 and the middle of July, with variations at either end depending on elevation and yearly seasonal variation. The species has been collected at elevations between 250 m and 1600 m. Distribution. Northern Italy (Trentino-Alto Adige and Friuli); southern Austria (Osttirol); Slovenia. The westernmost and southernmost locality is Pietramurata in Trentino north of Lago di Garda, whereas the northernmost locality is Lavant in East Tyrol, and the easternmost is Mount Triglav in Slovenia. Records from Italy were previously referred to as C. pyrrhulipennella (Baldizzone 1987, 1996; Baldizzone & van der Wolf 2004) but it now appears that that species does not occur in Italy. DNA barcode analysis. Tissue samples (dried legs) were shipped to the Canadian Centre for DNA Barcoding in Guelph for DNA extraction, amplification, and sequencing following standard protocols (deWaard et al. 2008). Barcoding efforts included the holotype and 6 paratypes of the new species as well as representatives of C. pulchripennella and C. pyrrhulipennella, including one record of the latter obtained from GenBank. The Barcode Identification Numbers (BINs) (Ratnasingham & Hebert 2013) in BOLD are used as registry designations for barcode clusters. Neighbor-joining trees and genetic distances were calculated with the Taxon ID Tree and Distance Analysis tools available in BOLD using the Kimura two-parameter (K2P) model of base substitution and Kalign sequence alignment. Details of the barcoded specimens and their photographs are available through the following dataset (http://dx.doi.org/10.5883/DS-C
