I. I. Dmitriev i osvoenie russkogo prostranstva.
No full textThis article begins with the proposition that I. I. Dmitriev’s influence on a younger generation of poets (including Žukovskij, Batjuškov, and Puškin) derives in large measure from the strong link that these contemporaries perceived between Dmitriev’s work and Russian geography. As his Memoirs attest, Dmitriev had felt since childhood that travel ought to engender artistic inspiration, but he was never to journey abroad and domestic territories were not yet sufficiently aestheticized to serve as an explicit source of artistic production. When he later returned to the Volga region of his childhood as an experienced traveler and established writer, however, Dmitriev was able to resolve the problem himself: in that specific biographical context, travel along the Volga was to unleash new poetic energies, allowing Dmitriev to create verses that articulated an unprecedented appreciation of the Russian countryside and became artistic models for subsequent poets
Neozygina Dietrich & Dmitriev 2006
No full textNeozygina Dietrich & Dmitriev, 2006 Diagnosis. Crown weakly to moderately produced medially, with pair of large brown or black preapical spots; mesonotum with basal triangles usually dark brown, contrasting with remainder of sclerite; forewing lacking distinct spots or oblique patterns, inner apical cell with base oblique; male pygofer with dorsal appendage well developed (except N. obsoleta, n. sp.), immovably fused to pygofer margin; one or more macrosetae present basad of dorsal appendage; ventral appendage present, usually elongate. Style apex truncate, footlike, with only two points, preapical lobe well developed. Connective U-shaped, without median anterior lobe, arms short. Aedeagus with dorsal apodeme well developed, usually T-shaped in posterior view, without sclerotized connection to dorsal pygofer appendage or anal tube; shaft often with paired or unpaired basal or distal processes, or both; unpaired basal process, when present, closely appressed to shaft. Distribution. Western United States south to Argentina. Notes. Phylogenetic analysis of morphological data recovered Neozygina as the monophyletic sister group to a clade comprising the New World genera Mexigina, Hepzygina, and Zyginama (Dietrich & Dmitriev 2006). The genus previously included 10 described species, 1 of which is here treated as a junior synonym. An additional 16 species discovered during this study are described below. The following key will separate adult males; females of most species may only be reliably identified through their association with males.Published as part of Dietrich, C. H. & Dmitriev, D.

No full textNeozygina expanda n. sp. (Figs. 1V, 4J–K) Diagnosis. Length of male 2.6 mm, female 3.1 mm. Closely resembling N. argentiniensis, but differing as follows: pygofer with dorsal appendage extended to apex; aedeagal shaft (Figs. 4J, K) in lateral view more strongly divergent from dorsal apodeme and with posterior margin evenly curved, processes formed by bifid apex strongly expanded and convergent distally. Material examined. Holotype male, ARGENTINA: La Rioja, Dept. Famatina, 10 km N Famatina, Hwy. 40, Sierra de Toro Negro, 4,450ft., 28.9591°S, 67.4705°W, 15/ 20 October 1997 (M.E. Irwin, F. D. Parker, S. Roig, Malaise trap, MEI 97-35) [INHS]. Paratype, 1 female, same data [INHS]. Note. The specific name refers to the expanded aedeagal apex, which distinguishes this species from other South American Neozygina.Published as part of Dietrich, C. H. & Dmitriev, D.

Cercopis oswaldheeri Dmitriev, 2020, nom.nov.
No full text† Cercopis oswaldheeri nom.nov. = Cercopis pallida Heer, 1853b: 97 (from Miocene) primary homonym of Cercopis spumaria var. pallida Zetterstedt, 1828a: 515 (synonym of Philaenus spumarius (Linnaeus, 1758); widespread species) and Cosmoscarta pallida (Walker, 1851b: 657); original genus Cercopis). Etymology: The species is named in honor of Oswald Heer (1809–1883), Swiss geologist and naturalist. Notes: This homonymy is covered by Article 23.9.5 of the Code. See also notes on Cercopis giebeli nom.nov. Since Cercopis pallida Heer, 1853 is not a frequently used name, a new replacement name is proposed here.Published as part of Dmitriev, Dmitry A., 2020, Nomenclatural changes in the suborders Auchenorrhyncha (Hemiptera) and Paleorrhyncha (Palaeohemiptera), pp. 25-53 in Zootaxa 4881 (1) on page 27, DOI: 10.11646/zootaxa.4881.1.2, http://zenodo.org/record/442571
Erasmoneura latiloba Dmitriev 2008, sp. n.
No full textErasmoneura latiloba sp. n. (Figs. 2, 3) Description: Body size (male, female): 2.4–2.5 mm. Coloration (male, female): Dorsum entirely reddish brownish, without color pattern. Anteclypeus dark brown. Thoracic venter entirely dark brown. Head (male, female): Crown fore margin strongly produced and angulate medially. Abdomen (male): 2S abdominal apodemes large, broad, reaching 3S posterior margin. Genitalia (male): Pygofer lobe rounded; dorsal appendage with distinct basal suture, but not movably articulated, simple, not extended beyond pygofer apex, straight in dorsal view, curved downward in lateral view. Style apex threepointed, second point very short, tooth like; third point elongate, about as long or longer than distance between other two points; angle between basal and third points less than 90°. Aedeagus with preatrium longer than shaft; shaft curved ventrally, broad in lateral view; depressed in crossection, with large lateral lobes, with small dorsal distal lobe; ventral processes absent; distal processes long, apical, slender. Type locality: Holotype ♂, USA, South Carolina, Aiken Co., Aiken, 12 V 1957 (J. R.U.), (CNC). Studied material: Paratypes: 3 ♂, 7 ♀, same data as holotype, (CNC); 1♂, 1♀, same data, (INHS). Host plant: Unknown. Note: The species name refers to the broad lobes on the sides of the aedeagal shaft. Like E. rubricata Van Duzee and E. margaritae Dmitriev & Dietrich, this species has a broad and depressed aedeagal shaft. It differs in longer distal processes of the aedeagus and smaller size.Published as part of Dmitriev, D. A., 2008, New and little known species of Erasmoneura Young (Hemiptera: Cicadellidae: Typhlocybinae), pp. 65-68 in Zootaxa 1851 (1) on page 66, DOI: 10.11646/zootaxa.1851.1.6, http://zenodo.org/record/513307
