Indzhov, S. — Hahnia kovblyuki sp. n. is described from forest habitats in West- ern Bulgaria and compared to its closest species, H. nava (Blackwall, 1841), using morphology and simple morphometry. Previous records of H. nava from Crimea are formally re-assigned to H. kovblyuki sp. n., and issues in the taxonomy of the Hahnia nava complex are briefly discussed. Ke y words : Crimea, Balkan Peninsula, species complex, morphometry, forest habitats, spiders, taxonomy. Introduction The genus Hahnia C. L. Koch, 1841 contains 13 described European species accord- ing to the World Spider Catalog (2025). These are small spiders which inhabit the ground layer of various habitats, exhibiting some specialization (species profiles at Harm, 1966, Kovblyuk et al., 2017). The males have relatively similar copulatory or- gans, unlike the mostly intricate and specific epigynal structures of the females (Figs at Harm, 1966, Kovblyuk et al., 2017). However, species complexes with sibling spe- cies are known from Europe, such as Hahnia ononidum Simon, 1875 and Hahnia thymorum Ledoux, 2014 (Ledoux, 2014). Hahnia nava (Blackwall, 1841) is a wide- spread species with a Transpalaearctic distribution (WSC 2025), reaching eastwards to Japan (Ichikawa, 2024). It is accordingly found in Bulgaria, where it mostly inhab- its open, grassland habitats (see material listed below), which coincides well with the Fauna and Systematics Zoodiversity, 60(3): 215–224, 2026 © Publisher Publishing House "Akademperiodyka" of the NAS of Ukraine, 2026.

Zoodiversity. 2026. Vol. 60, No. 3 216 information given by Harm (1966). However, Kovblyuk et al. (2017), in their treat- ment of Crimean Hahnia, reported H. nava predominantly from forest habitats, in- cluding the leaf litter of Fagus forests. In March 2023, a single male Hahnia was found in Western Bulgaria, in Lozenska Mts., under a stone in a beech forest. It could not be identified with certainty using the available European literature, but its simi- larity to Hahnia nava did not remain unnoticed. A direct comparison with unambig- uous males from the latter species showed a marked difference in the size of the pedipalps. The following two years, more material was collected at the same spot, with two more males being found under stones, while the majority of the individuals were found while sifting and turning older layers of beech litter. The consistent dif- ferences in the morphology of both sexes and in habitat preferences showed that this is a separate species, which is described herein. Material and Methods Individual spiders were collected while turning stones, searching through vegetation near ground level, or examining leaf litter, and preserved in approximately 75% etha nol. Epigynes and palps were separated using syringe needles, and the epigynes were cleared at room temperature in 80% lactic acid for 2–5 days. The materials were ex- amined under a Bresser Advance ICD stereomicroscope and a Levenhuk 50L Plus monocular microscope. Photos of genitalia were taken using a Samsung Galaxy A54 attached to the monocular microscope’s eyepiece and stacked using Picolay (Cypion- ka, 2025) and subsequently edited using GIMP (2025). Photos of the habitus were taken through the eyepiece of the Bresser stereomicroscope. Measurements were made using the diameter of the eyefield as reference (2.5 mm at 64 and 1 mm at 160 times magnification) and calculated from the pixels using the program GIMP (2025). All measurements are in mm. Scatter plot was made using R (2022) in R Studio (2026). The holotype, two male paratypes and four female paratypes are deposited at the deposited at the National Museum of Natural History, Sofia (NMNHS). Ad- ditional paratypes will be deposited in the author’s collection until they are also transferred to other institution collections in the future; some non-type speci- mens are in Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Sciences (IBER).

The species is morphologically similar to Hahnia nava (Blackwall, 1841) but can be separated by the following traits: the male cymbium length is ap- proximately 0.42–0.46 mm (approximately 0.35–0.38 mm in H. nava); the cymbium length:width ratio is below 1.47 (above 1.50 in H. nava); the cymbial furrow nearly reaches the tip of the cymbium and ends at a right angle (it reaches below the middle of the median apophysis and has a rounded ending in H. nava); the embolus origi- nates at 2 o’clock and runs far from the tegulum in its retrobasal quarter (it originates at 3 o’clock and runs closer to the tegulum in H. nava); the female copulatory ducts are longer and usually have larger posterior loops than in the closest species (shorter ducts and smaller loops in H. nava); the entrance portion of the copulatory ducts is more strongly pigmented ; the primary spermathecae are approximately 0.065– 0.070 mm in diameter (approximately 0.045 mm in H. nava); the preferred habitat is humid leaf litter in Fagus forests (open, often dry grasslands for H. nava); the overall colouration is somewhat paler than in H. nava, especially the prosoma and legs.

Epig yne and vulva. Epigyne flat, with no external structures other than two obliquely situated copulatory openings forming a V (Fig. 2, a). Copulatory ducts are long, thin, and form several loops (Figs 2, 4, 5), and the entrance portion is more heavily pigmented. Primary spermathecae spherical to slightly ovoid, rather big. Glandular structures are visible anteriorly of the dilated entrance parts of the copulatory ducts. Phenolog y. Adult specimens from both sexes were collected on snowless days in autumn and winter, from October until the first half of March. It is possible, however, that their maturity period is even longer, as no targeted searches were conducted in other parts of the year. Kovblyuk et al. (2017) also show activity in summer — June, August and September, which perhaps indicates a nearly year-round adult presence. General distr ibution. Bulgaria, Ukraine (Crimean Peninsula). Etymolog y.

(2017) C ym bi um w id th , m m Cymbium length, mm A New Species of Hahnia (Araneae, Hahniidae) from Bulgaria and Crimean Peninsula ISSN 2707-725X. Zoodiversity. 2026. Vol. 60, No. 3 223 Discussion Although frequently cited in taxonomic literature (WSC 2025), Hahnia nava appears to belong to a species complex that includes less-known taxa such as H. kovblyuki sp. n. and Hahnia hauseri Brignoli, 1978. The latter species is currently known only from females (Brignoli, 1978); however, it is likely widespread in the Western Mediterrane- an, as Barrientos (1985) and Lecigne et al. (2025) recorded morphologically similar females with short posterior loops. A definitive interpretation of these populations re- mains challenging without additional data on males beyond the descriptions provided by Barrientos (1985), which is beyond the scope of the present study. The identity of the male specimen illustrated by Harm (1966) as H. pusilla C. L. Koch, 1841 remains unclear. The curved median apophysis (MA) and the embolus originating at approximately 2 o’clock suggest that it belongs to the Hahnia nava complex; in contrast, H. pusilla possesses a straight MA and an embolus originating at approximately 5 o’clock (Almquist, 2006). This specimen is unlikely to be H. kovblyuki sp. n. because its cymbium length is only approxi- mately 0.35 mm (corrected from 3.5 mm) and it lacks the prominent cymbial furrow typical of the new species, appearing more similar to H. nava in several aspects. However, its length:width ratio of approximately 1.48 is more consistent with H. kovblyuki sp. n. Whether this record represents a misidentified H. nava, a small specimen of H. kovblyuki sp. n., or an undescribed member of this com- plex from Central European forests remains unknown, as the original illustra- tion does not permit a more definitive assessment. Variability in pedipalp size is evident in both H. kovblyuki sp. n. and H. nava, with the cymbial length of the latter ranging from 0.35 to 0.38 mm. While literature data (Harm, 1966; Almquist, 2006) report values around 0.37 mm, our measure- ments of Bulgarian material (N = 4) show that three males possess a cymbium length of approximately 0.35 mm, and only one specimen from Dragoman reaches 0.38 mm. Since this size variation is present in both species and occurs within single localities, it is interpreted as intraspecific variation. This variability implies that structural characters — specifically the cymbium length:width ratio and the extent of the cymbial furrow — are diagnostically more reliable than absolute measurements alone. Although no overlap in absolute palp size has been observed in the studied material, the ratio remains a stable and robust character for distinguishing these sibling species. In conclusion, the discovery of H. kovblyuki sp. n. highlights the taxonomic com- plexity within the Hahnia nava species complex in the Western Palaearctic. Given the subtle morphological differences and potential for overlapping absolute measurements, accurate identification must rely on a combination of genital proportions and habitat data. Further research involving molecular analysis and broader geographical sam- pling across Central Europe and the Mediterranean will be essential to fully clarify the boundaries of this complex and the status of related populations.
