Diagnosis.

Alloclita francoeuriae can be distinguished from A. canariensis and A. subitariella by the proximal dark brown streak of the forewing which reaches dorsum, and by the distal dark brown streak above fold which has a basal extension towards dorsum (Fig. 4 ). In the male genitalia (Fig. 7 ) it differs from A. canariensis by the shorter basal lobe of the valva and by shorter and broader cucullus. It differs from A. subitariella by the rounded tip of the right lobe of the valva and by the short shallow protrusions arising halfway along the anellar tube. In the female genitalia (Fig. 12 ) it differs from A. canariensis by the very shallow rounded anterior edge of segment VIII, by the band-shaped sclerotization of the ostium and by the sheet-shaped sclerotization of the signum.

Distribution

(Figs 17 , 18 ). Algeria, Tunisia, Morocco ( Koster and Sinev 2003), Spain: Canary Islands: Fuerteventura (new record). In northern Africa along the northern border of the Sahara.

Biology.

Larva in April burrowing under the woolly bark of Pulicaria undulata ( Asteraceae), after eating out the inside of the leaves it makes sand galleries attached to the crown of the root. Pupa pale brown, in a dense white cocoon, covered with sand and frass particles ( Walsingham 1905). Pulicaria undulata and other species of Pulicaria are also known from Fuerteventura ( Hohenester and Welß 1993).

Adults from the end of February to early April, in July ( Koster and Sinev 2003) and November.

DNA barcodes

(Fig. 19 ). We barcoded one specimen from Fuerteventura and one from Morocco. Both share BINBOLD:ADR0547. The intraspecific distance between the two is only 0.16%.

Remarks.

Walsingham (1905) cited a male and a female type, these are thus syntypes, and other original material does not belong to the type series (ICZN Art. 72.4.6, International Commission on Zoological Nomenclature 1999). We do not see a need to select either syntype as lectotype.
