Diagnosis. Ancylosis substratellum is distinguished externally by the comparatively broad weakly rounded before apex light grey forewing with narrow transverse lines ( Figs 3, 4 ). Ancylosis arenaceella Amsel, 1968 is somewhat similar but has the longer, distinctly up-turned rather than nearly straight labial palpus and the narrower, darker forewing. A comparatively short parallel-sided aedeagus with numerous minute spines in the vesica in combination with a broad sacculus are characteristic for the male genitalia ( Figs 57, 58 ). For the differences from A. oblitella , that has a short aedeagus too, see under that species. The female genitalia are well recognizable by a large number of very small spine-like signa ( Fig. 67 ).

Biology. Since 1999 the larvae were regularly observed in halophilic plant associations (salt-marshes, halophilic steppes, coastal plant communities) all over the Crimea—Sevastopol, vicinity of Saki and Yevpatoria, Meganom, Lysiacha Bukhta, Karadag, Barakol Lake, Tycha Bukhta, Dvoiakirna Bukhta, the vicinity of Prymorskyi, Yasnopolyanske and Lvovo villages, Arabatskay Strilka, Mysove, Kazantyp, Karalar steppe ( Fig. 79 ). The larvae feed on Limonium scoparium (Pall. ex Willd.) Stank. from mid June to late July and then from late August to October. Both first instars and adult larvae live usually singly or by 2–3 individuals in large spotted mines on leaves of the host plant (see Savchuk 2019). When taken out of mine the larvae can not penitarate in the leaf again and dying. Pupation occurs out of the feeding place in plant debris in a grey cocoon or within the mine. The mature larva most likely overwinters in debris before pupation. Adults fly from mid May to July and from July to August in two generations. The host plant and life cycle of this species was described for the first time by Budashkin (2014). The record of Artemisia monogyna as a host plant ( Robinson et al. 2010 –2019) is most likely misinterpretation of Christoph’s text, who wrote in the original description that adult was collected near (“um”) Artemisia monogyna , but did not mentioned the latter as a host plant (Christoph 1877: 286).

Distribution. Russia (Lower Volga, Caucasus, Southern Ural), West Kazakhstan (Uralsk), Turkmenistan ( Roesler 1973; Sinev 2008), Transcaucasus, Iran ( Sinev 1986), Turkey (new record). In Ukraine the species is known from Crimea ( Bidzilya & Budashkin 2004: 66) and Zaporizhzhia region ( Bidzilya et al. 2011: 70).

Remarks. Myelois substratella was described based on two females from Karsnovodsk and Sarepta ( Sinev et al. 2017: 489). The female from Karsnovodsk kept in ZIN was designated a lectotype ( Sinev 1990b: 425). A photograph of the second female, the paralectotype, was recently published ( Trofimova 2017: 625, pl. 42, fig. 6). The specimens from Ukraine match the photograph of the paralectotype and its genitalia are similar to those of figured by Roesler (1973: pl. 62, fig. 122; pl. 120, fig. 122).
