Table 1 in Morphometric analysis of fossil bumble bees (Hymenoptera, Apidae, Bombini) reveals their taxonomic affinities

Table 1. All known fossils described as bumble bees (genus Bombus) or as closely allied genera. Linear Discriminant Analysis (LDA) 1-3 are based on dataset 1. LDA 4 is based on dataset 2. LDA 5 is based on dataset 3. Key: * = fossil specimen without forewing picture/drawing available for geometric morphometric analyses. Abbreviations: Ap. = Apidae, B = Bombini. E = Electrapini. H = Holotype. S2: second specimen described by Cockerell (1908). B. = Bombus. C. = Calyptapis. O. = Oligoapis. Ol. = Oligobombus. P. = Paraelectrobombus. ° = the specimen was included in the shape space of the most similar clade. a = Jiménez-Moreno et al. (2010). b = Bachmayer et al. (1971). c = Akhmetjev (1973). d = Yang et al. (2007). e = Heizmann (1983). f = J. Prokop, pers. comm. (Wappler et al. 2012). g = Knor et al. (2012). h = Gray and Kittleman (1967). i = Paichelier et al. (1978). j = Evanoff et al. (2001). k = Antropov et al. (2014).
