According to the most recent taxonomic literature, three species of the genus Eresus are known in Central Europe, E. kollari, E. sandaliatus and E. moravicus. We recognized a fourth distinctive species from Hungary, which is described as Eresus hermani sp. n. Eresus hermani has an early spring copulation period, females have a light grey (grizzled) cephalothorax due to a heavy cover of lightly colored setae, and an epigyne with large flat areas posterior to the epigynal pit, while males are distinguished by a broad and blunt terminal tooth of the conductor. An updated and modified comparative table of Řezáč et al. (2008) to include all four Central European Eresus species, and a simple key to the species group’s species are given. Habitus, epigyne, vulva and conductor of E. kollari, E. moravicus and E. sandaliatus are also illustrated. An annotated list of papers illustrating E. hermani due to misidentifications is presented.


Ladybird spiders, Eresus


The velvet spiders (family Eresidae) are among the most attractive spiders in Europe. The family contains nine genera and 96 described species worldwide. The genus Eresus Walckenaer, 1805 contains 15 valid species from Europe, Africa and Asia, of which nine occur in Europe (World Spider Catalog 2015).

According to the latest studies (Řezač et al. 2008, Miller et al. 2012) three species of the Eresus sandaliatus group, Eresus kollari Rossi, 1846, E. sandaliatus Martini & Goeze, 1778 and E. moravicus Řezáč, 2008, occur in Central Europe.

The long and complicated scientific history of the Eresus sandaliatus group sensu Miller et al. (2012) is discussed in detail in Řezač et al. (2008), so only the Hungarian perspective is described here. The nomenclatural chaos is well illustrated by the fact that E. cinnaberinus might become valid, possibly as a senior synonym of E. kollari (Azarkina and Trilikauskas 2012).

The Hungarian spider fauna was first studied in detail by Ottó Herman, who also gave a detailed description of the Eresus genus (Herman 1879). Herman indicated the presence of two species, E. ruficapillus C. L. Koch, 1846 (regarded as misidentification of E. moravicus by Řezač et al. 2008 due the “reddish-yellowish hairs on the female”) and E. kollari (as E. cinabarinus Olivier), distinguishing α, β, and γ color variants, the latter corresponding to E. moravicus.

However, subsequent authors (e. g. Chyzer and Kulczynski 1918, Samu and Szinetár 1999) recognized only one species, E. cinnaberinus, with adults during the autumn.

Loksa (1969) mentioned a color form of female Eresus (E. niger var. ruficapillatus C.L. Koch) from the Mecsek hills and from the vicinity of lake Balaton, which has yellowish hairs on the carapace front, later identified as E. moravicus by Řezač et al. (2008).

Recently, Řezáč et al. (2008) considered E. cinnaberinus as nomen dubium [but see personal communication of Řezáč referred to in Azarkina and Trilikauskas (2012) as it might not] and proposed the name E. kollari Rossi, 1846 as valid. In this revision a distinct new species, E. moravicus was described (Řezač et al. 2008).

Eresus cinabarinus γ-color variant of Herman (1879), E. ruficapillus C.L. Koch and E. niger var. ruficapillatus (in Loksa 1969) were all identified as E. moravicus by Řezač et al. (2008). This means two Hungarian Eresus species, E. moravicus with a late spring–early summer copulation period, and E. kollari with populations mating in autumn (Kovács et al. 2010).

During an ongoing project aimed at mapping the distribution of Eresidae in Hungary, the presence of an Eresus species was observed with an early spring copulation period, which has unique morphological characters, and is described here as new to science.

Materials and methods

Specimens were either collected individually or by using pitfall traps, and stored in 70% ethyl-alcohol.

We studied 31 males, 15 females and 6 juveniles of E. kollari; 20 males, 25 females and 4 juveniles of E. hermani sp. n., and 19 males, 11 females and 3 juveniles of E. moravicus, and 2 males, 3 females and 2 juveniles of E. sandaliatus. All the measurements are given in millimeters (mm).

All specimens of the new species examined, including holotype and four paratypes, have been deposited in the Soil Zoological Collection (former Arachnoidea Collection) of the Department of Zoology, Hungarian Natural History Museum (HNHM) Budapest (curator Dr. László Dányi).

Specimens and copulatory organs were studied using a Leica MZ FL III stereomicroscope and photographed by Canon Q Imaging Micro 5.0 RTV at the Institute of Genetics, BRC. Scanning electron micrographs were taken with a Hitachi S-4700 microscope at the Department of Applied and Environmental Chemistry, University of Szeged, Hungary.

The genus Eresus in Central Europe has a long and difficult nomenclatural history. Some available “old names” were examined, such as Eresus illustris (presently considered nomen dubium, specimens are irretraceable), which is marked as possibly Hungarian (despite the fact Koch himself wrote “Vaterland: Unbekannt” [trans. Locality: Unknown]), but discarded it on the basis of the description and color image (Koch 1838, fig. 317), where the male has six black dots on the opisthosoma and only the dorsal side of hind femora as red, whereas E. hermani males have only four dots and clearly red hind legs patellae and tibiae, without any black, and tarsi and metatarsi are brownish grey (Fig. 1B). The female of E. illustris is unknown. The other possible candidate, E. fulvus Rossi 1846 (type specimens can no longer be found in NHMW), described by female specimens only, can also be excluded as a potential synonym, since they all have a large area covered by yellow/orange setae on the cephalothorax [“nitide fulvus” in the description of Rossi (1846)], whereas E. hermani females have no truly yellow setae on the prosoma at all; instead, its dorsal cephalothorax is light brownish-grey overall. According to Řezáč et al. 2008 (page 275.) E. fulvus Rossi differs from E. moravicus by “having spermatheca that are less lobed, and having copulatory ducts that are almost horizontal in the centre of the vulva.” By contrast, spermathecae of E. hermani are rather conspicuously lobed, at least as much as in Eresus moravicus (Figs 4C, F and 5B, D).

Dedicated to Ottó Herman (1835–1914), the Hungarian arachnologist and polymath, who first recognized color variants within Hungarian Eresus forms, to commemorate the 100th anniversary of his passing.


Females of this species differ from all other Eresus females by the carapace’s short, off-white to light brown hairs, intermingled with small clumps of long, black hairs, giving a light, grizzled appearance to the prosoma, and by an epigyne with a pair of flat plateaus adjoining the sides of the broad median lobe laterally. Males are characterized by the narrow groove and blunt, broad terminal tooth of the conductor, and distinguished from other Eresus species, except E. moravicus, by having almost entirely red hind legs. They differ from E. moravicus males by having red color on the thoracic dorsum only laterally, having a less prominent cephalic region with an almost flat area between PLE and PME, and by narrower strips of white setae on L I. This species has an early spring copulation period, and exhibits a marked difference in the sizes of the sexes: males are relatively small, while females are comparatively large among Central European Eresus spp. (Table 1).

Eresus hermani matures in August-September, wandering males can be found from the end of March to the end of April (inferred copulation period) and females lay eggs in June. This phenology clearly sets Eresus hermani apart from the other Hungarian Eresus species: E. moravicus matures in late spring and mates in early summer, while E. kollari matures in late summer – early autumn, immediately followed by a copulation period in autumn. The phenology of Eresus hermani is essentially the same as that of E. sandaliatus (Řezač et al. 2008), which, however, does not occur in Hungary or within the Carpathian Basin.

Remarks on misidentifications

Cs. Szinetár (2006): p. 23. Fig. 3

The caption of this figure says "Female Eresus cinnaberinus", but, in fact, the picture shows a female Eresus hermani sp. n., as is evident from the heavy cover of light setae on the prosoma and the base of chelicerae.

Kovács et al. (2010): figure 1C–F figure 2D

According to captions, fig. 1C–F of this paper depict the genital organs of female Eresus kollari. However, the anterior part of fissures of the epigyna are nearly parallel, epigynal pits are followed by large flat plateaus at the sides of median lobes, anterior copulatory ducts are round and weakly sclerotized, spermathecae strongly lobed, all features that distinguish Eresus hermani sp. n. unambiguously. Additionally, the epigyne shown in fig. 1E is grossly malformed, having supernumerary rudiments of fissures, a kind of abnormality frequent among females raised in captivity. Figure 2D is labeled as female Eresus kollari. Again, this figure shows a female Eresus hermani sp. n., as evidenced by the dense cover of lightly colored setae on the cephalic region and basal segments of chelicerae. The reason for these misidentifications is that at the time of writing, the authors (including the corresponding author of the present paper) considered females of Eresus hermani sp. n. as merely an extreme local variant of Eresus kollari. (Note: by contrast, fig. 2F. indeed shows a female Eresus kollari next to a male of the same species, as can be judged by the sparsely distributed light setae on the prosoma.)

Miller et al. (2012): figure 2A

Figure 2. A. of this paper is mislabeled as Eresus kollari, whereas in fact it depicts a female Eresus hermani sp. n. Again, the true identity of the specimen shown in this picture is revealed by the light color of the prosoma and basal chelicerae. The obvious reason for the misidentification is that at the time of the completion of this Atlas, the concept of Eresus hermani sp. n. as a discreet species was not yet formed.

Szinetár et al. (2012): table 2, figure 6

In this paper, figure 6. shows a female Eresus hermani sp. n. mislabeled as Eresus kollari. Heavy cover of the prosoma by lightly colored hairs gives away the identity of the depicted specimen.
