[Botany • 2025] Pilosella kalinensis (Asteraceae) • A New diploid Species in P. sect. Alpicolinae from the Rila Mountains in Bulgaria

  

 Pilosella kalinensis  Szeląg & Vladimirov,

in Szeląg & Vladimirov, 2025.  

Pilosella kalinensis is a new, diploid species, discovered in extreme habitats on the highest peaks in the Rila Mountains in Bulgaria. It belongs to the P. alpicola aggregate within P. sect. Alpicolinae and is distinguished by having somewhat larger capitula covered with very dense, long, blackish, straight trichomes. It is endangered by hybridization with P. rhodopea

ABSTRACT
With advances in molecular phylogeny, the Ursidae affinity of Ailuropoda is no longer controversial. However, the early evolution of Ailuropoda and its close relatives (the tribe Ailuropodini) is still unclear. In this study, we describe a new fossil discovery from Bulgaria, which represents a new taxon of Ailuropodini, ?Agriarctos nikolovi. The materials of Ailurarctos are restudied and the evolution and dispersal of Ailuropodini are discussed. Early Ailuropodini split into two lineages, one in Europe as Agriarctos (three species, whose assignment to the same genus is not certain), and one in southeastern Asia as Ailurarctos and later Ailuropoda. Ailurarctos is a paraphyletic group, with both known species as successive direct ancestors to Ailuropoda. Subtribe Ailuropodina is proposed here to include Ailurarctos and Ailuropoda. Turolian European Agriarctos paralleled with Ailuropodina in many aspects, which reflects similar adaptation towards a specific herbivorous diet.

 Reconstruction of ?AGRIARCTOS NIKOLOVI sp. nov. from Bulgaria.
The reconstruction was developed by a regressive estimate of the coloration of the modern Ailuropoda melanoleuca, based on the variation of the coloration of Ursus arctosUrsus arctos is used for calibration because the variation of its coloration (geographic, ecological, and individual) provides the most comprehensive model for the evolution of the coloration in Ursidae genera.

[Entomology • 2020] Incurvaria pirinella • A New Species of the vetulella species-group (Lepidoptera, Incurvariidae) from Bulgaria, with release of DNA Barcodes for European Species of Incurvaria


[3-5] Incurvaria pirinella Junnilainen, Kaitila & Mutanen, 2020
[14] Incurvaria circulella (Zetterstedt, 1839)

in Junnilainen, Buchner, Kaitila & Mutanen, 2020. 

Abstract
Incurvaria pirinella Junnilainen, Kaitila & Mutanen, sp. nov. is described from Bulgaria based on specimens collected by netting and artificial light from several low-elevation localities in Bulgaria. The species is morphologically and genetically most similar to I. triglavensis Hauder, 1912. Differences between these two species are present in external appearance and genitalia of both sexes. Additionally, I. pirinella shows a distance of 4.74% to its nearest neighbour I. triglavensis in the standard DNA barcoding marker (COI-5P). We provide preliminary observations of phylogenetic affinities of European Incurvaria and briefly discuss habitat preferences of some species. All species have distinct barcodes with minimum K2P divergences between species averaging 7.05% (range 1.2–12.8%). A world checklist of Incurvaria Haworth, 1828 is provided and DNA barcodes for all European species are here released. Finally, we document morphological variation in male genitalia within I. triglavensis Hauder, 1912.

Incurvaria pirinella Junnilainen, Kaitila & Mutanen, sp. nov.

Etymology: The name of the new species is derived from the Pirin mountain range, where the new species is widely distributed.

Diagnosis: 
Considering similar forewing ground colour and markings, Incurvaria pirinella (Figs 3–5) is externally closest to I. circulella (Fig. 14), but is easy to separate from it by the dark grey-brown fringe and distinct white spot in the forewing fringe present in I. circulella. Incurvaria pirinella is also widely allopatric as I. circulella occurs only in northern latitudes in Europe, e.g. the northern part of Sweden and Finland.

Although I. triglavensis is rather variable externally, it is always easy to separate from I. pirinella based on its relatively narrow forewing shape, paler ground colour and differences in forewing markings (Figs 6–11); see details in Suppl. material 2.

Incurvaria pirinella is easy to separate externally from Scandinavian I. vetulella (Figs 12–13) by a white narrow dorsal spot situated 2/5 from base and extending more than halfway across the forewing in I. pirinella. North European I. vetulella also typically have a distinctly broader dorsal spot, sparser forewing scaling and usually a pale medial area in the fringe, which is always absent in I. pirinella.
...

Distribution: Known from four different localities in the south-west corner of Bulgaria around the Struma river valley and its adjacent regions, which all belong to the Blagoevgrad district and the Pirin mountain range. The elevational range is wide: 200–1200 m, at least.

[Mammalogy • 2018] Talpa martinorum News from the Balkan refugium: Thrace has An Endemic Mole Species (Mammalia: Talpidae)


 Talpa martinorum
Kryštufek, Nedyalkov, Astrin & Hutterer, 2018

 Bonn zoological Bulletin. 67(1)

Abstract
 We utilized 1084 bp sequences of the cytochrome b gene to assess the taxonomic status of small blind moles from eastern Thrace in Bulgaria and European Turkey. So far, these moles were classified either as Talpa caeca or as T. levantis. Our study showed them to be genetically closer to T. europaea, T. aquitania, and T. occidentalis, albeit not being part of any of these species. We describe them as a new species, Talpa martinorum. n. sp. The new species differs from T. europaea, another mole occupying Thrace, by having a sealed palpebral fissure and a 1st upper molar with no parastyle, and by being smaller. The contemporary distribution range of T. martinorum n. sp. is small and restricted to the Black Sea coast between Burgas (Bulgaria) and Istanbul (Turkey). The species name is an eponym to the married couple Vladimir and Evgeniya Martino, two early students of Balkan mammals.

Key words. Balkans, cytochrome b, cryptic species, species delimitation, Talpa martinorum n. sp. N

Talpa martinorum n. sp. 

Diagnosis. A member of the subgenus Talpa. Medium-sized species with palpebral fissure sealed by a transparent skin (Fig. 3a). First upper molar (M1 ) lacks parastyle (Fig. 6a); the mesostyle is indistinctly bifurcate (Fig. 6a). Pairwise interspecific p-distances (> 9%) are within the range observed between other species of moles (e.g., within Talpa, interspecific distances average ca. 12%).

Etymology. Talpa martinorum n. sp. is an eponym to Vladimir Emmanuilovich Martino (Владимир Эммануилович Мартино, 1888–1961) and Evgeniya Veniaminovna Martino (Евгения Вениаминовнa Мартино, 1894–1979) née Stepanova (Степановa), ethnic Russians who in 1920 escaped the October Revolution by emigrating to the Kingdom of Serbs, Croats and Slovenes (Kingdom of Yugoslavia since 1929). In politically insecure and frequently violent Eastern Europe of the 20th century, the Martinos were refugees for more than three decades. In 1949 they moved to Bulgaria and in 1955 returned to Russia (at that time still Soviet Union). Inspired by G. S. Miller’s (1912) “Catalogue of the Mammals of Western Europe” they initiated mammal research in south-eastern Europe and named, among others, two Balkan endemics: Dinaromys bogdanovi (V. Martino & E. Martino, 1922) (Martino & Martino 1922: 413) and Talpa stankovici V. Martino & E. Martino, 1931 (Martino & Martino 1931: 53) (Fig. 8). While Vladimir had a degree in Biology from the University in Novorossiysk (1913), Evgeniya had no formal academic education. Despite this, she attained competency in mammalogy and successfully collaborated with her spouse, both in the field and cabinet. Although they published several joint papers (as V. and E. Martino), the contribution by Evgeniya is mainly ignored and she is nearly anonymous today (cf. Beolens et al. 2009). At least nine subspecific names for mammals with the epithet martinoi (see Appendix 3) were proposed by mammalogists between 1935 and 1971, and all are eponyms to Vladimir Martino. With the name martinorum n. sp. we stress the equal share by Evgeniya in the tandem “V. et E. Martino” and correct the injustice done to her contribution in the past decades. Along with Dorothea Bate (1878–1951) and Gabriele Neuhäuser (1911–1998) Evgeniya was one of the early women who studied the taxonomy of Palaearctic mammals already between the two great wars. In addition to their publications, a renowned legacy of Vladimir and Evgeniya Martino is their meticulously prepared and carefully labelled mammal collection, deposited primarily in the Natural History Museum London and the Zoological Institute and Museum of the Russian Academy of Sciences in St. Petersburg. For biographies of Vladimir Martino, see Mezentsev (1961), Paspalev (1962), Pusanov (1962), Zimmermann (1962), Gus’kov (1965), Taranenko (1999), and Boreiko (2001).

[Botany • 2017] Reappraisal of Campanula rotundifolia var. bulgarica Nejceff — A Neglected Taxon from Central Stara Planina Mountain, Bulgaria


Campanula nejceffii 

in Marinov & Stoyanov, 2017

Abstract

Campanula rotundifolia var. bulgarica Nejceff, a neglected taxon in the Bulgarian flora with currently uncertain status, was collected and studied at its locus classicus in the Sokolna (Koru Dere) Reserve of Central Stara Planina Mountain. A detailed morphological analysis of Nejceff’s original material and other related species clearly indicates that this is a distinct taxonomic entity worthy of species rank. Campanula nejceffii, stat. nov. is distinguished by a combination of its pubescent habit, ovoid to elliptic-lanceolate cauline leaves, clearly spreading to reflexed narrowly triangular-lanceolate calyx teeth, erect buds and flowers. Complete species description and comparison with selected species in the C. rotundifolia group are given. The lectotypes of two taxa — C. rotundifolia var. bulgarica Nejceff and C. rotundifolia subsp. neicevii f. pirinica Stoj. & Acht. are designated by the authors.
