Redescriptions of three Meyrick's Asiatic elachistid species, with descriptions of two new species (Lepidoptera, Gelechioidea)

Elachista heteroplaca Meyrick, Ptilodoxa lorigera Meyrick and Platyphyllis leucosyrma Meyrick are redescribed. Elachista albrechti sp. n. (Nepal) and Elachista planicara sp. n. (Kuriles) are described. E. heteroplaca, P. lorigera, E. albrechti and E. planicara are assigned to a species group related to the Elachista (Cosmiotes) freyerella group. Platyphyllis leucosyrma is placed in the Elachista tetragonella group. The genera Ptilodoxa and Platyphyllis Meyrick are considered to be synonyms of Elachista Treitschke (syn. n.). A lectotype is designated for E. heteroplaca

A review of species related to Elachista catalana Parenti (Lepidoptera, Elachistidae: Elachistinae), with descriptions of two new species

The taxonomy of Elachista (Aphelosetia) catalana Parenti, 1978 and its relatives is revised. Elachista modesta Parenti, 1978 is considered a valid species, stat. rev. and Elachista zuernbaueri Traugott-Olsen, 1990 is considered a synonym of E. catalana, syn. n. Elachista liskai sp. n. is described from Slovakia, and Elachista vulcana sp. n. from Morocco and Spain

A new method for collecting quantitative samples of insects associated with decaying wood or wood fungi

A trapping method for collecting quantitative samples of insects, especially beetles (Coleoptera) associated with decaying wood or wood fungi, is described. The trap is a modification of the window flight trap, attached to dead tree trunks, preferably close to the basidiocarps of polypores. Sampling during the summer of 1990 in southern Finland showed that large numbers of insects living in decaying wood or polypores can be caught with this method without destroying the habitat. Several threatened species were found during this sampling

The Elachistidae of southern Siberia and Central Asia, with descriptions of five new species (Lepidoptera)¹

The Elachistidae material collected during the joint Soviet-Finnish entomological expeditions to the Altai mountains, Baikal region and Tianshan mountains of the previous USSR is listed. Previous literature dealing with the Elachistidae in Central Asia is reviewed. A total of 40 species are dealt with, including descriptions of five new species: Stephensia jalmarella sp. n. (Altai), Elachista baikalica sp. n. (Baikal), E. talgarella sp. n. (southern Kazakhstan), E. esmeralda sp. n. (southern Kazakhstan) and E. filicornella sp. n. (southern Kazakhstan). The previously unknown females of E. bimaculata Parenti, 1981 and Biselachista zonulae Sruoga, 1992 are described

On species related to Elachista pollutella Duponchel (Lepidoptera, Elachistidae), with descriptions of four new Palaearctic species

The taxonomy of the relatives of Elachista (Aphelosetia) pollutella Duponchel, 1843 is clarified. The following species are described as new: Elachista jubarella sp. n. from Russian Caucasus, Elachista rutjani sp. n. from Russia: South Ural and Tuva, and Ukraine, Elachista enochra sp. n. from Turkmenistan, and E. cretula sp. n. from Kazakhstan and Turkmenistan. E. pollutella, previously only known from Central and Southern Europe, is recorded for the first time from Asian part of Russia in Altai Mts. and Mongolia. The identity of Elachista ilicrina Falkovitsh, 1986 is discussed

Two new Elachista species (Lepidoptera, Elachistidae) from the Polar Urals region, Russia

Two new species of Ehchista (Lepidoptera, Elachistidae) are described on the basis of material collected from the Sob River valley in the Polar Urals, and in the vicinity of Labytnangi on the shores of the Ob River: Elachista jaskai sp. n., which is assigned to fhe Elachista bifasciella group, and Elachista ripula sp. n., related to Elachista triatomea in the Elachista argentella group. E. ripula sp.n.is also reported from northern Finland. Diagnostic characteristics for the new species are given. Photographs of the habitus and genitalia are provided for the new species

Non peer reviewe

Elachista saarelai sp. n. (Lepidoptera, Elachistidae: Elachistinae), a new species from southern Finland

Elachista (Elachista) saarelai sp. n. is described on the basis of specimens reared from larvae in southern Finland. The new species belongs to the Elachista tetragonella group, and is a close relative of E. trapeziella Stainton, E. ornithopodella Frey, E. occidentalis Frey and E. kebneella Traugott-Olsen & Schmidt Nielsen. It differs from all these species by details in morphology and life history. The new species inhabits sheltered habitats. Carex digitata and probably also C. pediformis are recorded as its host plants. Diagnostic characters and illustrations are provided for the close relatives of E. saarelai sp. n

Japanese Elachista mining on the leaf of woody Poaceae (Lepidoptera: Elachistidae s. str.)

Elachista canis Parenti, E. sasae Sinev & Sruoga, and E. planicara Kaila are redescribed on the basis of Japanese specimens including many bred ones. Larvae of these species are leaf-miners on woody Poaceae. The female of E. canis and the male of E. planicara are described for the first time. In the original description of E. sasae, the characterisation of the female has proved to be based on specimens of E. planicara, and thus the female of E. sasae is described for the first time. Based onmorphological features, E. canis and E. sasae are considered to be very close to each other and are likely to represent one of the basal lineages of the sister-clade of the E. bifasciella-group, and E. planicara is likely to be an Oriental representative of the E. saccharella-group

Elachista leifi sp. n. from northern Finland (Lepidoptera, Elachistidae)

Elachista leifi sp. n. is described from material collected in Kuusamo, northern Finland. It is a very large species resembling E. kilmunella Stainton, E. parasella Traugott-Olsen and E. eskoi Kyrki & Karvonen. The species occurs on open bogs, swarming early in the morning at sunrise. The systematic position of E. leifi is discussed
