Type material. Holotype ♀ (GP 5436 J. Tabell, DNA sample 24527 Lepid Phyl): Morocco, Tiznit Prov., Mirleft 3.2 km SSW, 10 m, [29.5370 N 10.0595 W], 12.IV.2015, J. Tabell leg. http://id.luomus.fi/GBT.19 (coll. MZH). Paratypes: 7 ♂ (GP 5570 J. Tabell, DNA sample 24529), 32 ♀ (DNA sample 24530 Lepid Phyl) same collecting data as holotype (coll. TAB).
Diagnosis. C. adipella is most close to C. antiatlasella sp. n. Distinguishing features in the male genitalia are broader sacculus and its straight outer margin (slightly bulged in C. antiatlasella), smaller cucullus, broader appendix of juxta and shorter bundle of cornuti. In the female genitalia, longer anterior apophysis and colliculum, and distally more tapered sterigma distinguish C. adipella from C. antiatlasella. In C. sarehma, the spinulate section of ductus bursae is markedly longer than in C. adipella.
Molecular data. Three samples were sent for barcoding, resulting in 658 bp barcodes. The nearest neighbour to C. adipella is C. antiatlasella, with a 1.86 % minimum divergence. The barcodes of C. adipella exhibit no intraspecific variation.
Description. Adult. Wingspan 11–13 mm. Antenna white, annulated with brown. Scape white, below brown, not tufted. Labial palp white, apex brown, second article dirty white. Head, thorax and tegula brown, mixed with white. Forewing ochre with scattered blackish brown scales, white scales forming three narrow stripes. Costal stripe from base to ½. Costal fringe cilia pale ochre, apically brown, dorsal fringe cilia brownish grey. Hindwing pale grey, fringe cilia pale brownish grey. Abdomen light grey, slightly lustrous. In female antenna is darker annulated, and dark scales form a short medial stripe.
Abdominal structures. Sternal bar moderately short, no tergal latero-posterior bar. Transverse bar straight or slightly curved, both edges sclerotized. Tergal sclerite well sclerotized, 5x (in female 3x) as long as wide, covered with about 20 (in female 45) conical spines (on T3).
Male genitalia. Gnathos knob oval. Tegumen constricted medially, reinforced by a sclerotized ”Y”, pedunculum broad, crescent-shaped. Transtilla ropelike, slightly upcurved. Valvula broader than cucullus, weakly delineated, ventral margin rounded. Cucullus ear-shaped, almost parallel-sided. Sacculus well sclerotized; ventral margin slightly convex, oblique, ventrocaudal angle obtuse, rounded; lateral margin slightly concave, strongly sclerotized; dorsocaudal angle with a robust hook-shaped protuberance pointing inwards, apex dilated, at base close to dorsal margin a small tooth. Phallotheca very long, apex swollen, membranous, rods partially fused, narrow, with a small apical tooth. Vesica broad, with three spiniform cornuti forming a short bundle.
Female genitalia. Papilla analis elongate, narrow, covered with short bristles.Anterior apophysis 1.3x as long as sterigma, posterior apophysis 2x as long as anterior one. Sterigma trapezoidal, 1.6x as wide as long, strongly attenuated towards apex, proximal margin straight, distal margin rounded, covered with short bristles, medial excavation wide and deep. Ostium broadly U-shaped, situated medially on sterigma. Colliculum tubular, parallel-sided, 2x as long as sterigma, well sclerotized. Spinose part of ductus bursae shorter than colliculum, straight, with two lateral bands, posterior section of ductus bursae sclerotized, broad, tapered anteriorly, coiled, anterior section membranous, narrow, coiled. Corpus bursae round, with a leaf-shaped signum.
Biology. Early stages unknown.
Distribution. Morocco.
Etymology. Latin adeps, adipes = grease. The abdomina of almost all type specimens became greasy after a few weeks of collecting.
