description: <i>Ectoedemia (Ectoedemia) contorta</i> Van Nieukerken <b>Biology.</b> Hostplants: <i>Quercus pubescens</i> Willd., <i>robur</i> L., <i>Quercus faginea</i> Lam. is reported as possible new host from Spain (Lašt&amp;uring;vka and Lašt&amp;uring;vka 2008). Leafmines are inseparable from those of <i>E. albifasciella</i> and <i>heringi</i>. Th e larvae are separated from <i>E. pubescivora</i> by the absence of a chain of black plates in the earlier instars. Larvae found in August (Lašt&amp;uring;vka and Lašt&amp;uring;vka 1991; Lašt&amp;uring;vka et al. 1992) and October; adults fly from late May to July. <b>Distribution.</b> Czech Republic: Lašt&amp;uring;vka et al. 1992; Slovakia: Lašt&amp;uring;vka and Lašt&amp;uring;vka 1991; Italy: Karsholt et al. 1995 (detailed records below); Greece: Lašt&amp;uring;vka and Lašt&amp;uring;vka 1998; Spain: Lašt&amp;uring;vka and Lašt&amp;uring;vka 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. <b>Remarks.</b> Contrary to the earlier opinion that <i>E. contorta</i> and <i>pubescivora</i> 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 <i>E. albifasciella (E. contorta</i> and <i>albifasciella</i> in Valdieri), and leafmines and larvae of <i>albifasciella, contorta</i> and <i>heringi</i> are inseparable, males of the whole complex can only be separated by DNA analysis. Overall <i>E. contorta</i> seems to be the rarest species of this complex. <b>Material.</b> <b>Croatia:</b> 3♁, 7&amp;female;, Istria, Paz, 23.X.1999, mines with larvae, <i>Quercus pubescens,</i> ex l.
