Abstract

A key for identification of 39 species from 20 genera of Ukrainian notodontid moths based on the the eggs is provided. Reliable diagnostic characters, which do not disappear with the injury of eggs or eggs preserved for a long time in alcohol were used. The characters as egg shape, egg and chorion colour, shape of gnawed holes in eggs before setting out of caterpillars, the type of oviposition and the chorionic sculpture are applied. Clear characters that are typical for the live eggs, which vary in the process of egg development are revealed. These are characters of egg colour and pattern. In the key such characters are kept by stable signs that do not disappear aft er eggs traumatizing. The key is illustrated in details with photographs made using a digital camera and scanning electron microscope.

Abstract

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.

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.

Abstract

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

Abstract

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.

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.

Abstract

A nomenclatural synopsis of the alien species belonging to the tribe Senecioneae currently recorded in Italy (8 species) is presented. The occurrence at the regional level, as well as the level of naturalization and ecological notes for each taxon are provided. A diagnostic key of the non-native Italian species is also given. The names Cineraria petasitis (now Senecio petasitis), Delairea odorata, Eupatorium auriculatum (now Senecio deltoideus), E. fulvum, Mikania ternifolia var. senecioides, Senecio andryaloides, S. angulatus, and S. leucanthemifolius subsp. vernalis are typified on specimens preserved at E, F, P, SBT, and UPS, and on images by Lamarck, Lemaire, Sims, and Waldstein & Kitaibel. The type of the name S. pterophorus, as indicated by Iamonico in 2015, was wrongly reported as holotype and need to be corrected to lectotype according to the Art. 9.9 of ICN. The names Cacalia auriculata, Cacalia fimbrillifera (nom. nov., nom. superfl. et illeg. pro Eupatorium auriculatum), Cacalia scandens by Thunberg, Cineraria crassiflora, Eupatorium scandens by Link (nom. illeg.), Mikania senecioides (nom. illeg.), Senecio auriculatum, and Senecio mikanioides are also investigated and discussed.

Abstract

Pollen morphology of representatives of the genera Succisa and Succisella in the flora of Ukraine was studied using light and scanning electron microscopy. Pollen grains in both taxa were tricolpate, prolate, rarely oblate-spheroidal or spheroidal; large-sized. Their outline in polar view was subcircular, rarely trilobate, in equatorial view elliptical or rarely circular. Colpi short, of variable width, margins irregular with distinct, narrow margo, and blunt or acute ends. Exine sculpture was echinate-microechinate. The revealed characteristics of pollen grains are taxonomically significant at the generic and specific levels, and they can be used in pollen analysis. Palynomorphological data are consistent with the results of recent molecular phylogenetic studies. Data on pollen morphology also confirm taxonomic circumscription of Succiseae V. Mayer & Ehrend. Pollen grains in Succiseae are characterized by a tricolpate aperture type, which was probably ancestral in Dipsacaceae s. str.
