Newly described Palaearctic osmiine bee species

Wednesday, February 8th, 2017

An article in Zootaxa has recently been published dealing with the biology and taxonomy of Protosmia (Chelostomopsis) (Zootaxa, 4227, 287-294, 2017). One new species is described: Protosmia (Chelostomopsis) angustimandibulae spec. nov. from the Levant.

2 Palaearctic osmiine bee species newly described

Friday, June 24th, 2016

An article in Zootaxa has recently been published dealing with the biology and taxonomy of Hoplitis (Formicapis) and Hoplitis (Tkalcua) (Zootaxa, 4127, 105-120, 2016). Two new species are described: Hoplitis (Formicapis) coreensis spec. nov. from South Korea and Hoplitis (Tkalcua) emiratensis spec. nov. from the United Arab Emirates.

Hoplitis mitis granadae

Sunday, January 24th, 2016

Based on a single female, Tkalcu (1984a) described a new subspecies of Hoplitis mitis from the Sierra Nevada (Spain), i.e. H. m. granadae. Due to several remarkable differences, Tkalcu hypothesized that the new subspecies might possibly even represent a new species. Recently, the hitherto unknown male of H. m. granadae was found in osmiine bee material collected at 3200m a.s.l. at the southern slope of Pico Mulhacen in the Sierra Nevada by G. Losapio. Comparison of the males of H. m. granadae with those of the nominate subspecies generally revealed close morphological resemblance. However, as the morphological differences between the females of H. m. granadae and the nominate subspecies as stated by Tkalcu could be confirmed, the subspecific rank of the disjunct southern Spanish population of H. mitis appears to be well justified.

Osmia tergestensis and O. rhodoensis

Tuesday, January 12th, 2016

Warncke (1988b) recognised two subspecies of Osmia (Tergosmia) tergestensis, i.e. O. t. tergestensis occurring in south eastern Europe and O. t. ononidis distributed in northern Africa, southwestern Europe and Turkey. The investigation of a large material of O. tergestensis from its entire distribution range, which extends from northwestern Africa over southern Europe to Turkey and the Near East, revealed no clear morphological gaps nor consistent patterns with respect to e.g. colour of pilosity or density of tergal punctation between different populations. Similarly, Osmia (Tergosmia) rhodoensis arquata and O. r. ferina are newly treated as synonymous with O. rhodoensis. The characters given by Warncke (1988b) to distinguish these two subspecies from the nominotypical subspecies, such as colour of pilosity, density of clypeal and tergal punctation or development of male sternal swellings, do not seem to be consistent within populations or strong enough to justify subspecific rank.

Female of Hoplitis manuelae discovered

Sunday, October 11th, 2015

Hoplitis manuelae Müller, 2012 could not be assigned to a subgenus so far as only the male was known. Recently, the female of H. manuelae was discovered in a bee sample from southern Spain. The female characters clearly reveal that the species is a member of the subgenus Anthocopa. The lack of membraneous basal flaps on male sternum 6 suggests that H. manuelae might belong to a basal clade within Anthocopa.

New synonymy

Tuesday, April 14th, 2015

Chelostoma siciliae Müller, 2012 is a junior synonym of Chelostoma stefanii Nobile, 1995.

A new Nearctic subgenus of Osmia

Thursday, November 6th, 2014

Based on a new molecular phylogeny of the bee genus Osmia with emphasis on North American Melanosmia, Rightmyer et al. (2013) erected a new Nearctic subgenus of Osmia, Hapsidosmia, for a single species formerly treated as a member of the subgenus Melanosmia. Furthermore, they synonymized the two Nearctic subgenera Mystacosmia and Acanthosmioides under Melanosmia. This study also clarified the phylogenetic relationships among the different subgenera of Osmia, e.g. Osmia (Erythrosmia) is newly supported as sister to Osmia (Tergosmia). In addition, a key is given for the identification of the eight Nearctic subgenera of Osmia.

Erroneous synonymization

Monday, September 15th, 2014

As recently noticed by Ivanov et al. (2013), the synonymization of Pseudosmia taurica Radoszkowski, 1874 with Osmia dimidiata Morawitz, 1870 by Ungricht et al. (2008) is erroneous. P. taurica is a member of Hoplitis (Anthocopa) and appears to be closely related to Hoplitis bisulca (Gerstaecker, 1869).

Changes in subgeneric classification 5

Friday, November 1st, 2013

A recent study (Haider et al., 2013) on the phylogeny and floral hosts of Osmia bees of the subgenera Monosmia, Osmia and Orientosmia revealed paraphyly of the largest subgenus Osmia. Given this paraphyly in conjunction with the pronounced morphological resemblance among the species of all three subgenera, the authors propose to to merge Monosmia (1 species), Osmia (25 species) and Orientosmia (3 species) into one single large subgenus Osmia.

New synonymies 14

Friday, May 10th, 2013

Based on the type material, Heriades (Michenerella) dalmatica Maidl, 1922 is a junior synonym of Heriades (Michenerella) punctulifera Schletterer, 1889. Apart from the colour of the antenna, which is often yellowish in specimens from the Balkans and usually brownish in specimens from Turkey and the Near East, individuals from Europe and Asia exactly correspond to each other morphologically in both the female and the male sex.
