Teleiopsis diffinis (Haworth) was identified based on a single male specimen collected in Khakak, Mazandaran Province, deposited in the Hayk Mirzayans Insect Museum, Iranian Research Institute of Plant Protection. The genus Teleiopsis Sattler and T. diffinis are newly reported for the fauna of Iran. Taxonomic characterization of the species is provided and the examined adult male and its genitalia are illustrated.

Stathmopoda ficivora Kasy was identified based on a female specimen collected in the late of June 2013 in Dorbadam protected area, N. Ghuchan, Khorasan-e Razavi Province. This species is newly reported for the fauna of Iran. A brief taxonomic characterization of the species is provided and the examined adult female and its genitalia are figured.

A complete description of Acteniopsis gambronensis sp. n. is given based on three males and three females collected in the south of Iran, Hormozgan Province. The female of A. kurdistanella Amsel, 1959 is redescribed and illustrated and new distributional data for this species is also provided. Acteniopsis robustus Asselberges, 2010 is transferred to the genus Stemmatophora Guenée, 1854, S. robustus (Asselbergs, 2010), comb. n. A taxonomic review of the genus Acteniopsis is presented. Introduction The genus Acteniopsis Amsel, 1959 was erected to accommodate the type species A. kurdistanella Amsel, 1959. Acteniopsis belongs to the subfamily Pyralinae along with more than 1100 species in 134 genera. This subfamily is more diverse in Asia and Africa than in the western hemisphere (Munroe and Solis 1999; Nuss et al. 2003–2017). There is no obvious synapomorphic character for this subfamily (Solis and Shaffer 1999). Prior to the current study, Acteniopsis included only two species, A. kurdistanella and A. robustus Asselbergs, 2010 which had been described from Iraq and United Arab Emirates, respectively. The former species is also reported from Iran by Amsel (1961). According to Amsel (1959), this genus is generally close to Actenia Guenée, 1854 (presently known as Stemmatophora Guenée, 1854), although has very small and hardly recognizable maxillary palpi, and different, much shorter, and more broadly scaled labial palpi. The wing venation of these two genera is more or less similar accordingly; however in the hindwing of Acteniopsis the veins M2 and M3 originate from the same point, while in Stemmatophora they are on a short stalk. Also, in the forewing of Stemmatophora vein R5 is more or less on a long stalk at R3+R4, while in Acteniopsis R3+R4+R5 arising from a common point, and sometimes in female, R3+R4 has a short stalk with R5. Their antennae are differently ciliated ventrally: Stemmatophora has two rows of stout brushes of ciliae ending in numerous split hairs, while in Acteniopsis the ciliae are very tender, distally split in few fine hairs (Amsel 1959). During the study of Pyralinae of Iran, an unknown Acteniopsis species was found in the Lepidoptera collection of the Hayk Mirzayans Insect Museum (HMIM), Iranian Research Institute of Plant Protection (IRIPP). The aim of the present study is to describe this new Acteniopsis species which has been collected in Hormozgan Province in 1986. We also redescribe the female of A. kurdistanella based on the Iranian specimens collected in Chaharmahal va Bakhtiari, Fars, Hamedan and Kermanshah Provinces. Furthermore, the genus Acteniopsis is here revised.

Bucculatrix albella Stainton is newly reported for the fauna of Iran. The species is collected in Khorasan-e Jonubi and Zanjan Provinces as larvae and cocoon, and adult, respectively. In the former Province it was found on red date, Ziziphus jujuba Miller (Rosales: Rhamnaceae) in some orchards of Birjand during 2015-2016. This species may be considered as a severe pest of jujube in Iran in the future.

The phylogeny of the hydrophilid genus Sternolophus Solier, 1834 was examined in this study using 60 morphological adult characters, eight of them continuous and 52 discrete. The cladistic analysis resulted in a single most parsimonious tree with two major subclades corresponding, respectively, to species previously assigned to the subgenera Sternolophus s. str. Solier and Neosternolophus Zaitzev, although they are not re-instated. The species groups S. angolensis (Erichson, 1843) and S. solieri Castelnau, 1840 are recovered as monophyletic. The biogeography and diversification of the species of Sternolophus are briefly discussed.

Hedya tritofa, new species, is described and illustrated based on eleven males and five females collected in northern Iran (Gilan, Mazandaran, and Golestan provinces). Morphology and diagnostic characters of Hedya Hubner, 1825, Metendothenia Diakonoff, 1973, the Olethreutes group of genera, and the Neopotamia group of genera are discussed. We propose the resurrection of the combinations Hedya atropunctana (Zetterstedt, 1840), revised status, and H. separatana (Kearfott, 1907), revised status, and the new combination H. inouei (Kawabe, 1987).

Eighty-two species of Cochylini are recorded from Iran. Previous studies dealing with the tribe are summarized, and new data on the distribution of the Iranian species are provided. Aethes kandovana sp. n. is described; three genera, viz. Ceratoxanthis Razowski, Gynnidomorpha Turner, and Cochylidia Obraztsov, and the species Phtheochroa durbonana (Lhomme), P. syrtana Ragonot, P. inopiana (Haworth), P. decipiens (Walsingham), P. kenneli Obraztsov, P. subfumida (Falkovitsch), Cochylimorpha alternana (Stephens), C. armeniana (Joannis), C. kurdistana (Amsel), C. langeana (Kalchberg), C. montana (Razowski), C. nodulana (Moschler), C. nuristana (Razowski), Phalonidia manniana (Fischer von Roslerstamm), Gynnidomorpha permixtana ([Denis & Schiffermuller]), Ceratoxanthis iberica Baixeras, Eugnosta lathoniana (Hubner), Aethes conversana (Walsingham), A. deutschiana (Zetterstedt), A. eichleri Razowski, A. fennicana (Toll), A. scalana (Zerny), A. williana (Brahm), Cochylidia moguntiana Roessler, C. rupicola (Curtis), C. implicitana (Wocke), and Diceratura ostrinana (Guenee) are newly reported. The previously unknown male of Cochylimorpha fluens (Razowski) and the previously unknown females of C. scrophulana Razowski and C. montana (Razowski) are described.
