Abstract

The genus Alloclemensia n.gen. (type-species: Alloclemensia maculata n.sp.), with four species in the Palaearctic region and one species in the Nearctic region, is described and its species are revised. The genus comprises five species: mesospilella (Herrich-Schäffer) [= trimaculella (Herrich-Schäffer)], devotella (Rebel) [= muchei (Soffner), n.syn.] and three new species: americana from North America and unifasciata and maculata from Japan. The monophyly of the genus is demonstrated and the primary dichotomy within the genus is considered to lie between the two western Palaearctic species plus the North American species and the two eastern Palaearctic species. Keys to the species are provided and all species and their genitalia are described and illustrated. Two new combinations and one new synonymy are established and two lectotypes are designated.

Abstract

A preliminary cladistic-phylogenetic analysis of the four Holarctic genera of Adelidae recognized is presented. The monophyly of the superfamily Incurvarioidea is demonstrated on the basis of three possible synapomorphies, and that of the family Adelidae on the basis of three others. The subgenus Cauchas Zeller, 1839 is given generic status, as it is demonstrated to represent the sister-group of Nemophora Illiger & Hoffmannsegg, 1798 and Adela Latreille, 1796. Chalceopla Braun, 1921 is a new synonym of Cauchas Zeller, 1839. A key to the genera, based on males, is given.

Abstract

The taxonomy and nomenclature of the north European species of Ochsenheimeria Hübner, 1825, is reviewed and four species are recognized: vacculella Fischer von Röslerstamm, urella Fischer von Röslerstamm, mediopectinellus (Haworth) and taurella ([Denis & Schiffermüller]). A total of 12 species-group names are available for these four species. The genus Ochsenheimeria is characterized and its systematic position briefly discussed. Three keys to species based on external characters, male genitalia and female genitalia are provided. Adults and male and female genitalia are briefly described and illustrated. Five lectotypes are designated and two new synonyms are established.

Abstract

C. breviantennella n.sp. is described and figured from material collected in the northernmost parts of Sweden, Finland and the Kola Peninsula. Earlier is has been mistaken for Adela rufifrontella Tr. from which it easily is separated by its genitalia. C. brunnella n.sp. is known from its holotype only. Superficially it resembles C. leucocerella and albiantennella. A synonymic check list of the Palaearctic species currently referred to Cauchas is given and two new combinations are established, Nemophora canalella (Eversmann) and Nemophora infantella (Erschoff).

Abstract

The identities of all the Lepidoptera described by C.P. Thunberg have been reviewed critically. Most Lepidoptera described by Thunberg came from Europe, but he also named several species from Asia (probably all from Ceylon and Japan), South Africa and the New World. Almost all Thunberg's specimens are still extant and the identity of most of the species he named can therefore be based on examination of authentic material. The results are presented in the form of an alphabetical catalogue of the species names proposed by Thunberg, with cross-references to Thunberg's publications and a complete listing of all specimens of species named by Thunberg in the Thunberg collection. Thunberg's collection, the authorship of the species described in his dissertations and the dates of Fabricius' Entomologia Systematica 3(2) and Thunberg's Fauna Svecica 7, both published in 1794, are discussed. Lectotypes are designated for most species and several new synonymies and new combinations are proposed. The identity of the two species named marginella Fabricius, 1781 is established (under fimthriella Thunberg). Lectotypes of Tinea marginella Fabricius, 1781 and Tinea sexpunctella Fabricius, 1794 are designated.

Abstract

Notes are given on the identity and synonymy of five species of Lepidoptera described by Linnaeus, twenty-eight by Fabricius and two by Ström. Each species dealt with is treated under the apparent valid combination; for each species reference is given to the original description. Twenty-four new species-group name synonyms are introduced and nine new combinations are established: Nemaxera betulinella (Fabr.), Argyresthia arcella (Fabr.), Depressaria depressana (Fabr.), Chrysoesthia drurella (Fabr.), Brachmia blandella (Fabr.), Acleris laterana (Fabr.), Pseudohermenias abietana (Fabr.), Epinotia abbreviana (Fab.) and Acrobasis repandana (Fabr.). During the work two neotypes, twenty-seven lectotypes and two paralectotypes have been designated and are here cited for the first time.

Abstract

Synonymy between Irenicodes Meyrick, 1919 and Euproteodes Viette, 1954 is confirmed. Both genera are placed in synonymy with Elachista Treitschke, 1833.

Abstract

Material from Fennoscandia currently identified as Incurvaria vetulella (Zetterstedt, 1839) appears to comprise two superficially very similar species: 1. vetulella and I. circulella (Zetterstedt, 1839), the latter having been regarded as conspecific with or a form of vetulella for the last century. Lectotypes of both species are designated, the two species are briefly redescribed, differences are discussed, and adults, male and female genitalia are illustrated. I. circulella is reported from northern Norway, Sweden, Finland and the USSR.

Abstract

The basic divisions of the family Micropterigidae are discussed. Hypomartyria micropteroides n.gen., n.sp. from Osorno province, Chile, and Squamicornia aequatoriella n.gen., n.sp. from Napo province, Ecuador, are described; they are the first genuine micropterigids recorded from South America. The new taxa are assigned to the Sabatinca-group of genera, and their cladistic relations within the group are tentatively assessed. Hypomartyria appears to be derived from an ancestor closely similar to that of the entire group. Squamicornia exhibits some possible synapomorphies with Old World southern hemisphere taxa. There is no evidence that the two South American genera are each other's closest relatives.
