Context 1
... relatively parallel sided (average EW/EL = 0.88). The whole of the upper parts covered in flat, broadly oval, overlapping and mostly jet-black scales, with varying but small numbers of dark ginger coloured scales mostly distributed as a narrow line along the elytral suture and apex plus the posterior mid- point of the pronotum, with a whitish, slightly creamy coloured band of scales across both elytra, broad from the outer margin but narrowing considerably towards the elytral suture and upturned towards the small, black scutellum ( Figure 2A). The pale spots on the pronotum pure white as are the spots on the elytra close to the apices. ...
Context 2
... widest at hind edge narrowing towards anterior. The abdominal ventrites I-V are covered in white scales, slightly yellowish towards the margins and apex ( Figure 2B). Each ventrite carries a spot of black scales at outer margin and the black spot on ventrite 1 is set slightly in from the margin. ...

Anthrenus amandae Holloway, 2019, A. angustefasciatus Ganglbauer, 1904, and A. isabellinus Küster, 1848 are Dermestidae (Coleoptera) belonging to the Palaearctic A. pimpinellae (Fabricius, 1775) complex. All three species were collected from Mallorca. The distributions of the three species were habitat specific with A. angustefasciatus only found in acidic environments dominated by conifers. Anthrenus amandae and A. isabellinus were found in agricultural or cultivated environments. All three species were able to breed on bird feathers. The resulting final larval instar cases are described to facilitate species identification in the absence of adults.

... The species within this complex are considered difficult to differentiate since they nearly all have very similar colour patterns consisting of a white (or cream) trans-elytral band on a black (or dark brown) background with a scattering of orange or pale brown scales and a few white spots. As a result of this similarity, study of the A. pimpinellae complex species requires dissection to examine male genitalia and this approach has yielded many new species over the last 20 years (Kadej et al. 2007, Kadej and Háva 2011, Holloway 2019, 2020, 2021. Dissection continues to be the technique of choice to study the A. pimpinellae complex, although Holloway and Cañada Luna (2022) have translated aedeagus data into a key enabling identification of some western European complex species using colour pattern features. ...
... Some Dermestidae genera show great inter-specific colour pattern variation as illustrated by the images in Herrmann (2023). Some Dermestidae groups are indeed colourful but difficult to differentiate, for example, the Anthrenus pimpinellae complex of species (Kadej et al. 2007;Kadej and Háva 2011;Holloway 2019Holloway , 2020bHolloway , 2021Holloway and Bakaloudis 2020;Holloway et al. 2020aHolloway et al. , b, 2021, but certain other genera contain species that are straightforward to recognize. The Attagenus species of South Africa largely fall into the latter category. ...
The Dermestidae is a relatively poorly studied family of insects but with a high rate of species discovery. The South African region is particularly rich in Attagenus spp. many of which are distinctively patterned. This study provides an updated list of Attagenus spp. in South Africa with a complete literature review and an image-based identification key to the Attagenus species within South Africa. Images of most species are provided. With the rise in significance
of citizen science recording schemes, this study facilitates image-based identification and encourages both entomologists and citizen scientists to further contribute to the understanding of this beautiful Coleopteran family.
... Beal (1998) working on Nearctic Anthrenus, showed how important it is to dissect specimens for genital inspection to be certain of identification. Kadej et al. (2007) applied Beal's (1998) approach to the Palaearctic A. pimpinellae complex species and extended the number of known species to 17. Kadej and Háva (2011) added a further three species and Holloway (2019Holloway ( , 2020Holloway ( , 2021 yet another three bringing the total to 23 species. Here we report on another new species from the Palaearctic A. pimpinellae complex from Iran, Anthrenus (Anthrenus) muehlei new species. ...
A new species, Anthrenus muehlei Holloway and Herrmann (Coleoptera: Dermestidae: Megatominae), from Iran is described. Images of internal and external features are presented. Only female specimens were found and described, but the bursa copulatrix contains obvious sclerites enabling easy differentiation
from all other known species from the Palaearctic A. pimpinellae complex. The possible function and taxonomic implication of the sclerites is mentioned.
... and over one third of these 70 species constitute the Palaearctic A. pimpinellae Fabricius, 1775 complex. For a long time, species within this complex have been confused with each other, and only recently through the extensive use of dissection to inspect male genitalia have new species been discovered (Kadej et al. 2007, Kadej & Háva 2011, Holloway 2019, 2020, 2021 and taxonomic inaccuracies resolved , all facilitating identification using habitus features (Holloway & Cañada Luna 2022). A consequence of species confusion and limited identification resources has been an inadequate understanding of distributions (Holloway et al. in press). ...
Anecdotal evidence indicates that the holotype of Anthrenus goliath Saulcy in Mulsant & Rey, 1867 was lost along with other holotypes in Mulsant’s collection through neglect and poor storage prior to transfer to Museum National d'Histoire Naturelle, Paris, in 1944. Here, a (male) neotype for A. goliath is designated. The only feasible confusion species, A. corona Holloway, 2021 is considered to ensure the neotype is definitively A. goliath. Images of habitus, antenna, aedeagus, and sternite IX are illustrated. A female of the species is also shown. The only known location of A. goliath currently known is Egypt.
... Kadej et al. (2007) extended Beal's (1998) work and applied dissection to the Palaearctic A. pimpinellae complex species and found three new species. Kadej & Háva (2011) found three more species and Holloway (2019Holloway ( , 2020Holloway ( , 2021) added a further three species bringing the total number of species in the complex to 23. Unquestionably, there remains more species in the complex still to discover and other taxonomic issues to resolve ). ...
A new species Anthrenus bakaloudisi sp. nov. is described from Greece. Images of
external and internal features are illustrated. The aedeagus of A. bakaloudisi has slim
parameres so is compared with species that also have slim parameres from middle
and eastern Mediterranean and just into Asia: A. pfefferi, A. delicatus, and
A. warchalowskii. The new species differs internally from A. pfefferi in subtle ways,
but it is easy to distinguish between the species using external colour pattern. Anthrenus delicatus differs from A. bakaloudisi internally and ways of distinguishing between the two species externally are described. Anthrenus warchalowskii is only known from Iran and differs from A. bakaloudisi internally. No information could be found on the likely true range of A. bakaloudisi, so the species is currently only known from Macedonia, Greece in the region of Thessaloniki.
... Most specimens possessing this colour pattern were still deemed to be a variant or subspecies of A. pimpinellae. Since the middle of the twentieth century, a further 16 species have been described, mostly during the last 20 years (Hinton 1943;Kalik & Ohbayashi 1985;Háva 2001Háva , 2003Háva , 2018Kadej, Háva & Kalik 2007;Kadej & Háva 2011;Háva 2018;Holloway 2019Holloway , 2020Holloway , 2021. ...
Distributions of Anthrenus pimpinellae (Fabricius, 1775) and A. isabellinus Küster, 1848, are presented using data from verifiable online images, posted by citizen scientists. Anthrenus pimpinellae is distributed from north-western Europe into eastern and south-eastern Europe, and just into eastern Asia. Anthrenus isabellinus in Europe (and north Africa) is largely distributed across regions around the Mediterranean Sea. The species distributions overlap in south-eastern Europe, but do not overlap in western Europe and northern Africa. Until recently, the taxonomy of these two species was confused – consequently our knowledge of their distributions poor. Anthrenus pimpinellae is still considered by some authorities to be cosmopolitan; the current study shows that this is probably not the case.
... For a period of time, this group of species was considered to be one or a small number of species along with several subspecies and varieties (Háva, 2023). The group has been split into 24 valid species so far, largely based on genital structure (Kadej et al., 2007;Kadej and Háva, 2011;Holloway, 2019;2020;2021). However, many old descriptions of species never considered morphology and metrics, focusing as they did almost entirely on colour pattern. ...
A morphometric examination of Anthrenus flavipes flavipes LeConte 1854 from Central Macedonia, Greece is carried out and compared with data from previous publications. Size ranges for both sexes are generated. Males are significantly smaller than females. The body width/body length ratio is calculated. Images of body size range, antennal club and aedeagus are provided. Elements of the elytral colour pattern are considered in the light of LeConte's original description.
... Large collections of Dermestidae that carry extensive runs of species are proving very valuable sources of new species, in particular when dissection is carried out to inspect the genitalia. Beal (1998) and Kadej et al. (2007) demonstrated the value of dissection to identify species of Dermestidae, for example Háva (2022Háva ( , 2023b, Holloway (2019Holloway ( , 2020Holloway ( , 2021, Holloway and Bakaloudis (2020), , and Holloway and Herrmann (2023). Whilst going through runs of specimens collected in Spain, four specimens with an unusual colour pattern were noticed. ...
During an examination of Spanish Anthrenus spp. held in Andreas Herrmann's private collection, four specimens of a new species were noted: Anthrenus (Anthrenus) semipallens. Images of habitus features, including antenna, are presented and compared with other Anthrenus species thought to occur in Spain. A. semipallens is small so some comparison species could be eliminated courtesy of size. Although A. semipallens doesn't resemble the colour pattern of any other species, the possibility that A. semipallens is an unknown colour variant of a comparison species was considered. The A. semipallens specimens were dissected and the aedeagus compared with aedeagi from all other possible species. There was no similarity. Anthrenus semipallens is a valid new species.
