Hoplitis corsaria

Wednesday, April 3rd, 2024

In a recent publication (Journal of Hymenoptera Research, 97, 127-189, 2024), Le Divelec et al. (2024) elevate the Corsican endemite Hoplitis (Hoplitisannulata corsaria (Warncke, 1991) to species rank based on clear morphological gaps and substantially diverging COI sequences compared to Iberian populations.

New Hoplitis (Hoplitis) species

Wednesday, March 20th, 2024

In a recent article in Alpine Entomology (8, 65-79, 2024), Hoplitis (Hoplitis) onosmaevae Aubert is described, which shows a  spectacular geographic disjunction occurring in the southwestern French Alps and in mountainous areas in Turkey and northern Iraq, two areas separated by at least 2000 km. 

New synonymies

Monday, March 11th, 2024

R. Le Divelec discovered in the Muséum National d’Histoire Naturelle de Paris the male holotype of Protosmia (Protosmia) monstrosa (Pérez, 1895), which was assumed to be lost. The male clearly belongs to P. (Protosmia) tiflensis (Morawitz, 1875). Thus, P. monstrosa is a junior synonym of P. tiflensis and not identical with P. (Protosmia) mirabilis (Friese, 1899) as assumed by Alfken (1935b).

After examination of the types, the two following synonymies suspected by Branstetter et al. (2021) are confirmed: i) Osmia (Osmia) yanbianense Wu, 2004 is a junior synonym of O. (Osmia) opima Romankova, 1985 and ii) Osmia (Osmia) rufinoides Wu, 2004 is a junior synonym of O. (Osmia) rufina Cockerell, 1931.

Hoplitis turcestanica

Sunday, November 5th, 2023

Specimens from Ukraine and Astrakhan assumed to be Hoplitis (Alcidameaturcestanica by Fateryga & Proshchalykin, 2020) proved to be Hoplitis (Alcidameamollis (Ukraine, new country record) and a still undescribed H. (Alcidamea) species (Astrakhan). Most probably, H. turcestanica is restricted to Central Asia, it does neither occur in Ukraine nor in southern and central European Russia, and “H. turcestanica” in Banaszak & Romasenko (2001), Medvedev (1978) and Osytshnjuk et al. (1978) likely refers to H. mollis.

New Hoplitis (Hoplitis) species

Wednesday, August 16th, 2023

In a recent article in the Journal of Hymenoptera Research (96, 641-656, 2023), two new Hoplitis species of the subgenus Hoplitis from southern Russia, Azerbaijan and Central Asia are described, i.e. H. astragali and H. dagestanica. See species accounts for details.

Protosmia magnicapitis

Tuesday, August 1st, 2023

The examination of the holotype female of Protosmia magnicapitis (Stanek, 1969) revealed that the species does not belong to the subgenus Protosmia as assumed by Griswold (1985). Instead, it is a member of the subgenus Nanosmia as shown by the densely punctate apical margin of tergum 1, the almost cylindrical antennal flagellum and the small size. Among Protosmia species of the subgenus Nanosmia, P. magnicapitis is well characterized by the coarse punctation of scutum, scutellum and terga and particularly by the shape of the mandible, which is parallel-sided in its apical half and bears two minute and weakly separated teeth immediately followed by a long and reddish apical tooth.

Hoplitis camelina (Benoist, 1934)

Sunday, June 25th, 2023

Hoplitis camelina was described by Benoist (1934) based on a female collected near Ain Leuh in Morocco. This female differs from European females of H. acuticornis (Dufour & Perris, 1840) by its yellowish-red rather than (yellowish-)white pilosity of head, mesosoma and metasoma and by the reddish rather than blackish marginal zones of the terga. Recently, T. Wood collected a series of females and males of H. camelina at the same locality and date near Guercif in southern Morocco, which show a strong variability in the colour of the body pilosity and the tergal marginal zones. Some specimens have a (yellowish-)white body pilosity and dark marginal tergal zones as in European specimens of H. acuticornis, whereas others have a yellowish-red body pilosity and lightened tergal marginal zones as in H. camelina and still others a (yellowish-)white body pilosity and lightened marginal tergal zones. As no structural differences between North African specimens of H. camelina and European specimens of H. acuticornis were found in either sex, the status of H. camelina as a species of its own does not seem to be justified. Therefore, H. camelina is newly regarded as conspecific with H. acuticornis. Pending a future revision of the H. acuticornis group, H. camelina is tentatively treated as a subspecies of H. acuticornis as proposed by Warncke (1991h).

Hoplitis taurica (Radoszkowski, 1874)

Sunday, June 25th, 2023

Pseudosmia taurica was described by Radoszkowski (1874) based on female and male specimens collected near Salguir on the Crimean peninsula. Radoszkowski placed this species in a newly established genus Pseudosmia, to which he added – according to the current classification – eight further species belonging to Hoplitis (Anthocopa), Osmia (Erythrogastra), Osmia (Helicosmia), Osmia (Hoplosmia) and Osmia (Metallinella). Radoszkowski’s description is far from being sufficient to narrow down the identity of P. taurica. Due to the laterally toothed male tergum 6, P. taurica is probably a member of the genus Hoplitis, which is supported by the author’s remark that the new species is morphologically close to H (Anthocopabisulca (Gerstaecker). The types of P. taurica were neither found in Krakow, where a large part of the bee collection of Radoszkowski is housed, nor in Moscow or St. Petersburg (L. Przybyłowicz, A. Fateryga and M. Proshchalykin, personal communication), which suggests that they are lost. Due to the insufficient species description and the unavailability of the types, P. taurica Radoszkowski, 1874 is therefore newly regarded as a nomen dubium.

New Hoplitis (Stenosmia) species

Wednesday, June 21st, 2023

In a recent article in the Entomologist’s Monthly Magazine (159, 79-86, 2023), I. Cross described Hoplitis halophila, a new species of the subgenus Stenosmia from southern Iberia. See species account for details.

Hoplitis corcyraea elevated to species rank

Saturday, November 19th, 2022

Tkalku (1979) described Hoplitis corcyraea as subspecies of H. yermasoyiae (Mavromoustakis 1938) mainly differing from the latter by the yellowish-red rather than whitish metasomal scopa. The investigation of a series of H. corcyraea from mainland Greece revealed additional morphological differences, e.g. in the length of the mouthparts, in the formation of the tergal hair bands and in the punctation of the tergal discs. Thus, H. corcyraea is elevated here to species rank.
