A revision of the subfamily Spilomelinae (Lepidoptera, Crambidae) in Iran with description of a new species.

Spilomelinae specimens collected by the first author during the past 15 years, as well as those housed in the Hayk Mirzayans Insect Museum (HMIM), were studied. Udea rajabii sp. n. is newly described. Arnia nervosalis nervosalis Guenée, 1849 is considered as a senior synonym of A. nervosalis hyrcanalis Amsel, 1961 syn. n., and Mecyna subsequalis subsequalis (Herrich-Schäffer, 1855) is regarded as a senior synonym of M. subsequalis lutulentalis (Lederer, 1858) syn. n. The genus Maruca Walker, 1859 and seven species, namely Maruca vitrata (Fabricius, 1787), Dolicharthria stigmosalis (Herrich-Schäffer, 1848), Duponchelia caidalis Oberthür, 1888, Mecyna lutealis (Duponchel, 1833), Metasia gigantalis Staudinger, 1871, M. rosealis Ragonot, 1895, and Udea accolalis (Zeller, 1867) are newly reported from Iran. The hitherto unknown female of Palpita persicalis (Amsel, 1951) is described and illustrated for the first time. Moreover, diagnostic characters in most of the species compared with the similar regional species, as well as intraspecific variations of each species are presented and discussed, if present. Additional data on distribution of the Spilomelinae species of Iran are also provided.

Notes on taxonomy and distribution of some Palaearctic Ancylosis Zeller, 1839 (Lepidoptera: Pyralidae: Phycitinae).

The taxonomy of several Ancylosis species is revised. Four new synonyms are established: Ancylosis brunneonervella Roesler, 1970 syn. nov. of Ancylosis albicosta (Staudinger, 1870); Ancylosis psammicola (Roesler, 1970) syn. nov. of Ancylosis leucocephala (Staudinger, 1879); Ancylosis unicolorella (Roesler, 1970) syn. nov. of Ancylosis pallida (Staudinger, 1870). The following taxa are re-instated as separate species: Ancylosis delicatella (Möschler, 1860) spec. rev., stat. nov. and Ancylosis ciliatella (Zeller, 1872) spec. rev., stat. nov. are taken out from synonymy with Ancylosis rhodochrella (Herrich-Schäffer, 1852); Ancylosis deliciosella (Caradja, 1910) spec. rev., stat. nov. is taken out from synonymy with Ancylosis hellenica (Staudinger, 1870); Ancylosis macedonica (Schawerda, 1937) spec. rev., stat. nov. is taken out from synonymy with Ancylosis muliebris (Meyrick, 1937). Heterographis costalbella Amsel, 1954-the junior homonym of Heterographis costalbella Mabille, 1906, is taken out from synonymy with Ancylosis syrtella (Ragonot, 1887) and re-instated as separate species under replacement name Ancylosis amseli Yepishin, 2020 nom. nov. Ancylosis ciliella (Amsel, 1961) syn. nov. is transferred from synonymy with A. rhodochrella to synonymy with A. delicatella. Female genitalia of A. amseli and A. delicatella as well as male genitalia of A. deliciosella and genitalia of both sexes of A. ciliatella are described for the first time. Ancylosis deliciosella is recorded as new for Iran, A. delicatella-for Azerbaijan and Kazakhstan, Ancylosis rhodochrella (Herrich-Schäffer, 1852)-for Georgia, Ancylosis larissae Bidzilya, Budashkin Yepishin, 2019-for Russia, Kazakhstan, Iran, Afghanistan, Mongolia and China, and Ancylosis yerburii (Butler, 1884) is new for Russia and Kazakhstan.
