Phylogenetic relationships of Ceratitis fruit flies inferred from nuclear CAD and tango/ARNT gene fragments: Testing monophyly of the subgenera Ceratitis ( Ceratitis) and C. ( Pterandrus)

Systematic studies of Ceratitis (Tephritidae) fruit flies using molecular (i.e., COI, ND6, and period genes) and morphological (plus host-use characters) data have recently challenged the monophyly of the subgenera Ceratitis ( Ceratitis) and Ceratitis ( Pterandrus). In this paper, we report on the p...

Description
Summary:	Systematic studies of Ceratitis (Tephritidae) fruit flies using molecular (i.e., COI, ND6, and period genes) and morphological (plus host-use characters) data have recently challenged the monophyly of the subgenera Ceratitis ( Ceratitis) and Ceratitis ( Pterandrus). In this paper, we report on the phylogenetic utility of three single-copy nuclear gene regions (two non-overlapping fragments of the carbamoylphosphate synthetase, CPS, locus of CAD, and a fragment of tango) within these taxa and investigate evolutionary relationships based on a concatenated ca. 3.4 kb data set that includes the six protein encoding gene regions. Results indicate that the CAD and tango genes provide useful phylogenetic signal within the taxa and are compatible with the previously studied genes. The two subgenera, as currently classified, are not monophyletic. Our molecular phylogenetic analyses support a revised classification in which (1) the subgenus C. ( Pterandrus) comprises two lineages called A and B, (2) the C. ( Pterandrus) B species should be included in C. ( Ceratitis), and (3) the newly defined subgenera C. ( Pterandrus) (= Pterandrus section A) and C. ( Ceratitis) [= C. ( Ceratitis) + C. ( Pterandrus) section B] are reciprocally monophyletic.
