Journal ArticleDOI
Phylogeny of the Coleoptera Based on Morphological Characters of Adults and Larvae
John F. Lawrence,Adam Slipinski,Ainsley E. Seago,Margaret K. Thayer,Alfred F. Newton,Adriana E. Marvaldi +5 more
TL;DR: In order to infer phylogenetic relationships within the extraordinarily speciesrich order Coleoptera, a cladistic analysis is performed, in which 516 adult and larval morphological characters are scored for 359 beetle taxa, representing 314 families or subfamilies plus seven outgroup taxa representing seven holometabolan orders.
Journal ArticleDOI
The beetle tree of life reveals that Coleoptera survived end‐Permian mass extinction to diversify during the Cretaceous terrestrial revolution

Lawrence,Adam Slipinski,David R. Maddison,David R. Maddison,Brian D. Farrell +25 more
TL;DR: A phylogeny of beetles based on DNA sequence data from eight nuclear genes, including six single‐copy nuclear protein‐coding genes, for 367 species representing 172 of 183 extant families provides a uniquely well‐resolved temporal and phylogenetic framework for studying patterns of innovation and diversification in Coleoptera.
Journal ArticleDOI
Phylogeny and evolution of Staphyliniformia and Scarabaeiformia: forest litter as a stepping stone for diversification of nonphytophagous beetles
Duane D. McKenna,Brian D. Farrell,Michael S. Caterino,Charles W. Farnum,David C. Hawks,David R. Maddison,Ainsley E. Seago,Andrew E. Z. Short,Alfred F. Newton,Margaret K. Thayer +9 more
TL;DR: The phylogeny of Staphyliniformia is reconstructed using DNA sequences from nuclear 28S rDNA and the nuclear protein‐coding gene CAD for 282 species representing all living families and most subfamilies, with a representative sample of Scarabaeiformia serving as a near outgroup, and three additional beetles as more distant outgroups.
Journal ArticleDOI
Comparative morphology and evolutionary pathways of the mouthparts in spore‐feeding Staphylinoidea (Coleoptera)
TL;DR: The external morphology of the mouthparts in the guild of spore-feeders among the coleopterous superfamily Staphylinoidea is surveyed, evaluating the influence of different phylogenetic and ecological starting points on the formation of their mouthparts.
