Phylogeny of Chilicola (Hylaeosoma)(Hymenoptera:Colletidae) Based on Morphological and Morphometric Data of Extant and Fossil Species, with Description of Seven New Species

Combined data approach is used to establish a phylogeny of the bee subgenus Chilicola (Hylaeosoma) Ashmead 1898 (Colletidae: Xeromelissinae). Results of phylogenetic analyses are presented, based upon 92 morphological characters and 3 wing landmark shape configurations. Monophyly of the subgenus is supported. Chilicola longiceps Ashmead 1898 is grouped with megalostigma morphogroup and renders longiceps morphogroup paraphyletic. Two C. (Hylaeosoma) fossils are nested within the tree with C. electrodominica Engel 1999 occupying a more derived position than C. gracilis Michener and Poinar 1995. Effectiveness and reliability of continuous characters is discussed and compared to other methods. Seven new species are described: Chilicola (Hylaeosoma) herberti Miklasevskaja sp. nov., Chilicola (Hylaeosoma) rufotergata Miklasevskaja sp. nov., Chilicola (Hylaeosoma) paveli Miklasevskaja sp. nov., Chilicola (Hylaeosoma) liudmilae Miklasevskaja sp. nov., Chilicola (Hylaeosoma) boyacense Miklasevskaja sp. nov., Chilicola (Hylaeosoma) boliviana Miklasevskaja sp. nov., Chilicola (Hylaeosoma) lambayequense Miklasevskaja sp. nov..
