Daladerini View in CoL , and Phylogenetic Position of Colpurini

The relationships recovered within our well-supported Clade B do not strictly agree with previous studies ( Schaefer 1965, Li 1997, Fang and Nie 2007). Daladerini and Latimbini were recovered as the sister of all other tribes within Clade B. We found support for a clade comprised of Cloresmini , as well as its sister group relationship with Colpurini + Mictini that has not been previously proposed. Schaefer (1965) included Cloresmini within his Coreus -subgroup C with other tribes not recovered in this clade (although Mictini was included in a separate Coreus -subgroup within a larger Coreus -group).

Amyot and Serville (1843) described and classified Dalader in the same family-group as genera from Mictini , but it was subsequently treated as a distinct group by Stål (1873). Li’s (1997) morphological phylogenetic hypothesis suggests that the Daladerini are sister to Acanthocerini and Acanthocephalini , in support of Stål’s (1873) treatment of the tribe as separate from the Mictini . Our results also support the exclusion of the sampled daladerine genera from Mictini but predominately find new evidence for the paraphyly of this tribe with respect to Latimbini , which has a drastically different gross morphology. Schaefer (1965) assigned Daladerini to his Coreus -subgroup B; he assigned the Latimbini to the Homoeocerus - group but recognized that the position of Latimbini was uncertain.

Our results for the phylogenetic placement of Colpurini and treatment as a tribe within Coreinae is contradictory with all other studies ( Štys 1964, Kumar 1965, Schaefer 1965, Ahmad 1970, Li 1997). Past studies have characterized the Colpurini as ‘primitive’ but with many characters (primarily genitalia) suggesting an ‘intermediate’

phylogenetic position between Pseudophloeinae , Hydarinae , and other Coreinae (see Štys 1964; Kumar 1965; Schaefer 1965; Ahmad 1970; Li 1996, 1997). Thus, our results are novel and suggest that genitalic features, as well as external features, should be reevaluated in light of our molecular hypothesis.
