Ectoedemia (Ectoedemia) suberis (Stainton)

Figs 33, 34, 48

Diagnosis. Male Ectoedemia suberis is separated from the four following species by the completely white androconial field on the hindwing, surrounding a white hair-pencil, and scales not reaching the dorsal margin of the hindwing (Figs 33, 34). E. caradjai has a basal white streak on the forewing and lacks the androconial field; other similar Ectoedemia (such as haraldi ) are usually smaller, have fewer antennal segments and have no hairpencil. Females are distinguished from E. andalusiae , heckfordi and phaeolepis by the hairy abdominal tip, and from hendrikseni by the larger number of antennal segments. Male genitalia differ from E. andalusiae and hendrikseni by the very slight basal bump, which is much more distinct in the other species, whereas this bump is virtually absent in E. phaeolepis and caradjai (Fig. 48). See also E. phaeolepis . Aedeagus at 360–400 µm distinctly longer than in E. phaeolepis and andalusiae (less than 350µm). In female genitalia hard to distinguish from E. andalusiae or E. phaeolepis , apart from slight statistical differences in numbers of setae on anal papillae and number of convolutions in ductus spermathecae (6 in andalusiae , 5.5 in heckfordi , 4.5 in phaeolepis ).

Biology. Hostplants: evergreen oaks Quercus ilex L., Q. rotundifolia Lam. , Q. suber L. and Q. coccifera L. and possibly on semi-evergreen oak Q. faginea Lam. (vacated mines only) (Van Nieukerken 1985;Van Nieukerken et al. 2004a; 2006). Mine not separable from the similar mines on evergreen oaks of E. andalusiae , phaeolepis and hendrikseni , but on Q. coccifera , E. andalusiae is more often found than suberis . Univoltine, with larvae from January (Algarve, Andalusia) to late April (Spanish mountains, France) and adults flying from July to October.

Distribution. Earlier records from Tunisia, based on leafmines only, are confirmed by the record of reared adults below. Given the fact that the closely related E. hendrikseni , E. andalusiae and E. phaeolepis cannot be separated by their mines, the previous records from Algeria on the basis of their leafmines (Van Nieukerken 1985) should be reconsidered and regarded as doubtful, although in the light of distribution data suberis is still the most likely candidate.

Diagnosis. Ectoedema hendrikseni males are separated from similar suberis by the brown hairpencil and both from suberis and andalusiae by the white scaling on hindwing reaching the dorsal margin of the wing, with brown scales towards base. In the genitalia the shape of the valva is characteristic for the male, as is the number and length of the setae on the female T8.

Description. Male (Figs 35–36). Forewing length 2.6–3.0 mm, wingspan 6.0–6.8 mm. Head: frontal tuft ochreous, collar greyish; scape yellowish white; antenna with 36–40 segments, brown-grey. Th orax and forewings fuscous black, thorax with some grey scales anteriorly and on metathorax, metallic shiny. Forewing: basal half covered with coarse black scales, medial fascia sharp, ochreous, narrowed towards costa; distal to fascia are individual coarse scales distinct, sometimes with ochreous ground colouration between them, especially on edge; cilia-line interrupted; cilia ochreous grey; underside grey. Hindwing: grey, with brown hair pencil near frenulum, surrounded by white androconial scales in basal half, partly brown towards base; cilia grey; underside ochreous grey. Abdomen and legs ochreous brown-grey.

Female. Forewing length 2.8–3.0 mm, wingspan 6.3–6.6 mm. Antenna with 29– 34 segments. Th e coloration as in male, hindwing grey, without androconial scales.

Male genitalia (Figs 45, 49). Vinculum distinctly concave anteriorly. Tegumen with a bulbous, rounded pseuduncus, with several long setae. Gnathos broad, its processes and connecting bar of equal breadth, lateral processes rounded at their ends, only slightly shorter than central element. Valva broad, with an angular inner lobe on its base and with only slightly elongate distal process, sublateral processes about ¼ transtilla length. Aedeagus with distinct cathrema, with numerous very small cornuti in vesica, carinae simple, slightly curved, not pointed.

Female genitalia (Figs 54, 58, 62). T7 on either side with a patch of ca 35 long setae along margin with T8; T8 on disc with ca 40 long setae on either side; T8 with rounded corners, slightly indented posteriorly. Papillae anales broadly rounded, with many short setae, approximately 80–90 on each. Apophyses short and thick. Vestibulum with distinct vaginal sclerite and a spiculate pouch with small spines arranged as pectinations. Corpus bursae ca. 790µm long, almost globular, covered with minute pectinations; signa dissimilar, resp. ca 415 and 610 µm long (n=1), approximately 2.1–2.9 as long as wide. Ductus spermathecae with about 5.5 narrow sclerotized convolutions.

Biology. Hostplants: only reared from Quercus coccifera L. (Van Nieukerken 1985; Van Nieukerken et al. 2004).
