Nomenclatural note. The corrected name of this species was published relatively recently with the reference to its presumable original spelling ( Anikin et al., 2016): Caloptilia roseipennella ( Hübner, 1796) . This is an unjustified emendation, according to the Article 33.2.3. of the International Code of Zoological Nomenclature, since the original publication does not contain any evidence of an inadvertent error which must be corrected in accordance with the Article of 32.5.1.

In the original publication, the name “ Tin. Roscipennella ” is clearly printed in the description of the species and is repeated in the caption to the plate of figures 29 ( Fig. 1). This author’s cursive cutline to the drawing of the moth, representing only the species name, is also clearly read as roscipenella (with a single “ n ”; doubling of this consonant is shown with a horizontal bar above the letter). Hübner did not explain the origin of the species name. This name can be connected with the black dots which are located against the pale, uniformly coloured forewing background defined by the author, and resemble drops of dew (the Latin words ros and roscidus mean “dew” and “dewy”, correspondingly) instead of the “roseus” colour of the wings as it was assumed by the authors of the corrected name. In addition, Hübner subsequently applied this name without correction, precisely as “ roscipennella ”, for example, in the work where the genus Caloptilia was described *.

New record. Caloptilia roscipennella was detect- ed in the southern part of Belarus, where it presumably penetrated from Poland or Ukraine. Earlier, it was found in the Mielnik Village ( 52°20′N, 23°3′E), Podlaskie Voivodeship, Poland in 2011 ( J. Busžko, pers. comm.). In Belarus, the species was record- ed for the first time on 7.VIII. 2015 in Zhabinka ( Zhabinka District ) and the Verholesye Village ( Kobryn District ), then on 8.VIII.2015 – 16 X. 2015 in Kobryn ( Kobryn District ), Svislach ( Svislach District ), Baranovichi ( Baranovichi District ), Brest of the Brest Province; in Loyew ( Loyew District ), Gomel and Rechytsa ( Rechytsa District ) of the Gomel Province ( Fig. 2). In subsequent years, the species was found only in the same places GoogleMaps .

name Roscius , except for one case known to me, Waigeum miraculum f. roscia Fruhstorfer, 1908 . Probably, the latter name is formed in the same way as the name by Hübner. The description of Tinea roscipennella was given in one sentence: “Sie hat eine helle Falchfarbe, und ihre Oberflügel sind ihrer ganzen Lange nach zweymal schwarz punktirt”, and the vernacular name proposed by the author for the species is Falchfederfarbige. The enigmatic word “falch” in Upper German means “cow or horse of fawn colour” (An Etymological Dictionary of the German Language by F. Kluge, 1891 translated by J.F. Davis). A. V. Sinchuk et al.

Bionomics and economic importance. The mines are epidermal, silvery, lower- or upper-surface corridors ( Fig. 3 A) widening into a blotch. The corridor is widening into a narrow tentiform mine, usually close to the leaf margin ( Fig. 3 B). After vacating the mine, the larva lives in a leaf roll ( Fig.3 C) ( Patočka & Zach, 1995; Ellis, 2007). Pupation takes place in the hyaline-looking membranous cocoon outside the mine ( Fig.3 D).

In 2015, C. roscipennella damaged 15–20% of Juglans regia leaves in Baranovichi, approxi-

That is, Hübner meant the “pale yellowish-brown colour” (Cambridge Dictionary) of his new species. This has nothing to do with “roseus”colour,therefore, it is indeed possible to exclude a typo in the species name. The phrase “...Oberflügel sind ihrer ganzen Lange nach zweymal schwarz punktirt” (upper wings along the entire length with double black punctation) also has little to do with the word roscidus meaning “full of dew, wet with dew, dewy; moistened, watered, wet” (A Latin Dictionary by Ch. T. Lewis & Ch. Short, 1879). However, Hübner knew the name Noctua roscida [Denis et Schiffermüller], 1775 (= Tinea mately 10% in Rechytsa, and less than 5% in oth- er localities. In Belarus, the distinctive damage pattern of the walnut leaf miner was observed on J. regia trees planted in parks and large gardens. The significance of this species as a pest of J. regia in Belarus cannot be established with certainty, but severe damage caused to plants is possible in the future. Therefore, it is important to study this alien species trophically associated with the common walnut, the plant which is promising for the wide cultivation in Belarus.

roscidella Fabricius, 1794) since he quotes both of these synonyms in the same work of 1796 (p. 7). Obviously, the species name roscida reflects the colouration of the forewings which are in this species as if splattered, but not with dew, but rather with dirt. Probably, Hübner wanted to reflect the similar character, with the same word, but he “lost” a part of the first stem in the compound word roscidopennella (he later followed the correct spelling in his names Tortrix roscidana Hübner, 1799 and Epelis roscidaria Hübner 1823 ). Therefore, the etymology proposed by the authors of this article is plausible. ( Editor-in-Chief’s Note).
