“…Bombus lapidarius currently includes five subspecies based on colour patterns (Fig. A) (Reinig , ; Tkalců ; Rasmont ) despite their poor reliability as diagnostic characters in bumblebees (Bertsch & Schweer ; Carolan et al . ): (i) B. lapidarius lapidarius (L.) in the European plains, Balkans and West Anatolia, (ii) B. lapidarius decipiens Pérez 1890 in the Iberian Peninsula and in Southern Italy, (iii) B. lapidarius caucasicus Radoszkowski 1859 in the North East Anatolia and Caucasus, (iv) B. lapidarius eriophorus Klug 1807 in Caucasus and (v) B. lapidarius atlanticus Benoist 1928 in the Moroccan Atlas.…”

Methods for species delimitation in bumblebees (Hymenoptera, Apidae, Bombus): towards an integrative approach

et al. 2015

Delimitation of closely related species is often hindered by the lack of discrete diagnostic morphological characters. This is exemplified in bumblebees (genus Bombus). There have been many attempts to clarify bumblebee taxonomy by using alternative features to discrete morphological characters such as wing shape, DNA, or eco‐chemical traits. Nevertheless each approach has its own limitations. Recent studies have used a multisource approach to gather different lines of speciation evidence in order to draw a strongly supported taxonomic hypothesis in bumblebees. Yet, the resulting taxonomic status is not independent of selected evidence and of consensus methodology (i.e. unanimous procedure, majority, different weighting of evidence). In this article, we compare taxonomic conclusions for a group of taxonomically doubtful species (the Bombus lapidarius‐group) obtained from the four commonly used lines of evidence for species delimitation in bumblebees (geometric morphometric of wing shape, genetic differentiation assessment, sequence‐based species delimitation methods and differentiation of cephalic labial gland secretions). We ultimately aim to assess the usefulness of these lines of evidence as components of an integrative decision framework to delimit bumblebee species. Our results show that analyses based on wing shape do not delineate any obvious cluster. In contrast, nuclear/mitochondrial, sequence‐based species delimitation methods, and analyses based on cephalic labial gland secretions are congruent with each other. This allows setting up an integrative decision framework to establish strongly supported species and subspecies status within bumblebees.

“…polytypic species) (Reinig, 1935;Pittioni, 1938;Rasmont, 1983a;Lecocq et al, 2014) most probably fostered by historical biogeographic events (Reinig, 1937Lecocq et al, 2013a,b). These geographic variations have been used by several authors to define many subspecies mainly based on variation in colour patterns (Vogt, 1909(Vogt, , 1911Pittioni, 1938;Krüger, 1951Krüger, , 1958Rasmont, 1983a;Rasmont et al, 2008).…”

“…Bombus lapidarius included five subspecies (Rasmont 1983;Reinig 1935Reinig , 1970Tkalců 1960) (Lecocq et al 2013a, in press). Nevertheless, eriophorus (not studied by Lecocq et al 2013a) and B. caucasicus have been considered as two forms of the same taxon by Reinig (1935) while Rasmont (1983) …”

“…The Psithyrus female (queen) invades an established nest of its host bumblebee species and lays eggs that are reared by host workers into new Psithyrus sexuals, since all Psithyrus species lack a worker caste. Typically, Psithyrus females of a given species only parasitize nests of one, or a few, host species (Richards 1927;Reinig 1935;Alford 1975;Fisher 1987;Williams 2008), but their host invasion behavior can be highly variable (Kupper and Schwammberger 1995;Frehn and Schwammberger 2001).…”

Host Specific Social Parasites (Psithyrus) Indicate Chemical Recognition System in Bumblebees

et al. 2010

Semiochemicals influence many aspects of insect behavior, including interactions between parasites and their hosts. We studied the chemical recognition system of bumblebees (Bombus) by examining the cuticular hydrocarbon cues of 14 species, including five species of social parasites, known as cuckoo bees (subgenus Psithyrus). We found that bumblebees possess species-specific alkene positional isomer profiles that are stable over large geographical regions and are mimicked by three host-specific cuckoo parasites. In three host-cuckoo associations where mimicry is poor, possibly due to recent host shifts, these cuckoos produce dodecyl acetate a known chemical repellent that allows the cuckoos to invade their host colonies. Our findings indicate cuckoos use two chemical mechanisms, mimicry and repellents, to invade their hosts, and this may reflect different stages of an ongoing dynamic arms race.
