South American micropterigid moths: two new genera of the Sabatinca-group (Lepidoptera: Micropterigidae)

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 others closest relatives.

A cladistic analysis of the Holarctic genera of adelid moths (Lepidoptera: Incur varoidea)

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.

A taxonomic revision of the species of Alloclemensia n.gen. (Lepidoptera: Incurvariidae s. str.)

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-Schaffer) [= trimaculella (Herrich-Schaffer)], 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.

Notes on some Lepidoptera described by Linnaeus, Fabricius, and Ström

Notes are given on the identity and synonymy of five species of Lepidoptera described by Linnaeus, twenty-eight by Fabricius and two by Strom. 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.

The identity of Incurvaria vetulella (Zetterstedt, 1839) and I. circulella (Zetterstedt, 1839), two distinct species (Lepidoptera: Incurvariidae)

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.

Cauchas breviantennella n.sp. from NW Europe and C. brunnella n.sp. from Uzbekistan, with a check-list of the Palaearctic Cauchas species (Lepidoptera: Adelidae)

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).
