Ectoedemia (Ectoedemia) contorta Van Nieukerken View in CoL

Biology. Hostplants: Quercus pubescens Willd. , robur L., Quercus faginea Lam. is reported as possible new host from Spain ( Laštůvka and Laštůvka 2008). Leafmines are inseparable from those of E. albifasciella and heringi . Th e larvae are separated from E. pubescivora by the absence of a chain of black plates in the earlier instars. Larvae found in August ( Laštůvka and Laštůvka 1991; Laštůvka et al. 1992) and October; adults fly from late May to July.

Distribution. Czech Republic: Laštůvka et al. 1992; Slovakia: Laštůvka and Laštůvka 1991; Italy: Karsholt et al. 1995 (detailed records below); Greece: Laštůvka and Laštůvka 1998; Spain: Laštůvka and Laštůvka 2008. Here recorded new for Croatia. A record from Ukraine: Crimea ( Puplesis 1994), although possible, is not accepted, as it is based on a male only. Wide distribution from Central Spain through northern Italy to Slovakia and northern Greece. Not yet recorded from France.

Remarks. Contrary to the earlier opinion that E. contorta and pubescivora are vicariant species (Van Nieukerken 1985), they appear to be (almost) sympatric at least in Spain and northern Italy (e.g. Conna). Both can also be found in sympatry with E. albifasciella ( E. contorta and albifasciella in Valdieri ), and leafmines and larvae of albifasciella , contorta and heringi are inseparable, males of the whole complex can only be separated by DNA analysis. Overall E. contorta seems to be the rarest species of this complex.
