title: Data from: Phylogeny of the beetle supertribe Trechitae (Coleoptera: Carabidae): unexpected clades, isolated lineages, and morphological convergence

description: Using data from two nuclear ribosomal genes and four nuclear
 protein-coding genes, we infer a well-resolved phylogeny of major lineages
 of the carabid beetle supertribe Trechitae, based upon a sampling of 259
 species. Patrobini is the sister group of Trechitae, but the genus
 Lissopogonus appears to be outside of the Patrobini + Trechitae clade. We
 find that four enigmatic trechite genera from the Southern Hemisphere,
 Bembidarenas, Argentinatachoides, Andinodontis, and Tasmanitachoides, form
 a clade that is the sister group of Trechini; we describe this clade as a
 new tribe, Bembidarenini. Bembidarenini + Trechini form the sister group
 of remaining trechites. Within Trechini, subtribe Trechodina is not
 monophyletic, as three trechodine genera from Australia (Trechobembix,
 Paratrechodes, Cyphotrechodes) are the sister group of subtribe Trechina.
 Trechini appears to have originated in the continents of the Southern
 Hemisphere, with almost all Northern Hemisphere lineages representing a
 single radiation within the subtribe Trechina. We present moderate
 evidence that the geographically and phylogenetically isolated genera
 Sinozolus (six species in the mountains of China), Chaltenia (one species
 in Argentina and Chile), and Phrypeus (one species in western North
 America) also form a clade, the tribe Sinozolini. The traditionally
 recognized tribe Bembidiini sens. lat., diagnosed by the presence of a
 subulate terminal palpomere, is shown to be polyphyletic; subulate
 palpomeres have arisen five times within Trechitae. Anillini is
 monophyletic, and the sister group of Tachyini + Pogonini + Bembidiini +
 Zolini + Sinozolini; within anillines, we confirm earlier results
 indicating the eyed New Zealand genus Nesamblyops as the sister to the
 rest. Sampled New World Pogonini are monophyletic, rendering the genus
 Pogonus non-monophyletic. Tachyina and Xystosomina are sister groups.
 Within Xystosomina, the New World members are monophyletic, and are sister
 to an Australia-New Zealand clade. The latter consists of the genus
 Philipis as well as taxa not previously recognized as xystosomines:
 Kiwitachys, the “Tachys” ectromioides group, and “Tachys” mulwalensis.
 Within Tachyina, the subgenus Elaphropus is not closely related to other
 subgenera previously placed in the genus Elaphropus; we move the other
 subgenera into the genus Tachyura. Tachyina with a bifoveate mentum do not
 form a clade; in fact, a bifoveate mentum is found in Xystosomina,
 Sinozolini, Trechini, Trechitae and its sister group, Patrobini. Extensive
 homoplasy in the morphological characters previously used as key
 indicators of relationship is supported by our results: in addition to
 multiple origins of subulate palpomeres and bifoveate menta, a concave
 protibial notch has arisen independently in Anillina, Xystosomina, and
 Tachyina. Phylogenetically and geographically isolated, species-poor
 lineages in Trechini, Bembidarenini, and Sinozolini may be relicts of more
 widespread faunas; many of these are found today on gravel or sand shores
 of creeks and rivers, which may be an ancestral habitat for portions of
 Trechitae. In addition to the description of Bembidarenini, we present a
 diagnosis of the newly delimited Sinozolini, and keys to the tribes of
 Trechitae.
