The eggs of 9 species Noctuidae belonging in 4 subfamilies (Plusiinae, Eustrotinae, Acontiinae and Pantheinae) are examined, described, and illustrated with SEM. The diagnostic characters of the eggs of examined species are given.

The Chorionic Sculpture of the Eggs of Some Noctuinae (Lepidoptera, Noctuidae) from Ukraine

Descriptions and scanning electron microphotographs of the eggs of 10 species from 7 genera of the subfamily Noctuinae occurring in Ukraine are provided. The diagnostic characters of the genera and species are selected.


The eggs of 10 species Noctuidae from 6 subfamilies (Acronictinae, Metoponiinae, Cuculliinae, Heliothinae, Condicinae and Bryophilinae) occurring in Ukraine are examined, described, and illustrated with SEM. Th e diagnostic characters of examined species are carried out

The Chorionic Sculpture of the Eggs of Some Xyleninae (Lepidoptera, Noctuidae)

Eggs of sixteen species of fifteen genera of the subfamily Xyleninae occurring in Ukraine are described and illustrated with scanning electron microphotographs. The diagnostic characters of the genera and species are se-lected.

Formation of Pattern and Diagnostic Instar Features of the Head in Caterpillars from Genus Peridea (Lepidoptera, Notodontidae)

Pattern and colouration of caterpillar head of all larval instar of 7 species from genus Peridea Stephens, 1828 are studied. Formation of caterpillar head pattern in ontogenesis is discussed. Diagnostic characters, both specific and larval instars, are recorded for the first time. Key to species according to larval instars is given. Evidently, only larvae of the 1st instar demonstrate different directions in the pattern formation. This characteristic can be used for clearing of taxonomic relations in the genera and on the earliest ontogenetic stages (1st larval instar) only. In the following (2nd-5th) instars, the pattern became more or less of the same type. It depends on stripes shape or colouration only and can serve as good specific diagnostic character. To determine larval instar, both width of the head capsule and head pattern should be taken into account.


The eggs of one species from family Nolidae (subfamily Chloephorinae) and seven species from family Erebidae (subfamilies Hermeniinae, Hypeninae, Phytometrinae and Catocalinae) occurring in Ukraine are examined, described, and illustrated with SEM. The diagnostic characters of examined species are proposed.


Genetic and Morphological Variability and Diff erentiation of Mussels (Bivavia, Unionidae, Anodontinae) in Ukraine. Mezhzherin S. V., Yanovich L. M., Zhalay Е. I., Vasilieva L. А., Pampura М. М. - Th e study of allozymes variation and sequence analysis of two mitochondrial genes supports the concept that there are four species of subfamily Anodontinae in the Eastern European fauna, three of them; Anodonta cygnea Linnaeus, 1758; A. anatina Linnaeus, 1758; Pseudanodonta complanata (Rossmassler, 1835) are indigenous and one is invasive (Sinanodonta woodiana Lea, 1834). Th is paper analyzes morphological diagnostic features of which some can be used in identification of these species.


Pyrgotid Flies assigned to Apyrgota. I. New Species and Synonyms in Eupyrgota (s. str.) (Diptera, Pyrgotidae), with Description of a New Subgenus. Korneyev, V. A. - Eupyrgota scioida Hendel, 1908, the type species of the genus Apyrgota Hendel, 1909, syn. n. is shown to belong in Eupyrgota Coquillett, 1899. Th e diagnoses of the genus Eupyrgota and the subgenus Eupyrgota (s. str.) are reconsidered. E. alienata (Walker, 1861) comb. n., E. brahma (Hendel, 1914), comb. n., E. aequalis (Malloch, 1939), comb. n., E. angustifrons (Bezzi, 1914), comb. n., and E. armipes (Hendel, 1914), comb. n. are transferred into Eupyrgota (s. str.). Th e following synonymy is established: Eupyrgota Coquillett, 1899 = Apyrgota Hendel, 1909, syn. n.; E. alienata (Walker, 1861) = E. scioida Hendel, 1908, syn. n.; and E. brahma (Hendel, 1914) = Adapsilia nocturna Bezzi, 1914, syn. n. E. nyambene V. Korneyev, sp. n. is described based on a single female from Kenya; the new species belongs in the varipennis subgroup, but diff ers from other species by having a slender fore femur (thickened in E. varipennis Curran) and the mid femur with a femoral organ (absent in E. rugosigenis Hendel). A monotypic subgenus Asipyrgota subgen. n. (type species: Adapsilia flaviseta Malloch, 1929) is established; it shares the presence of the nipple-like processes of the prosternum, a generally robust appearance, and presence of 3 pairs of scutellar setae with members of the subgenus Eupyrgota s. str., diff ering by the absence of paired ventro-apical hooks on the oviscape.
