Remarks.

A small unmarked leaf litter species, known best from the southeastern United States, but recently reported from Canada in the BOLD barcode database (Ratnasingam and Hebert 2007, 2013), from the extreme southern point in Ontario (Point Pelee National Park, specimens PPELE142-11, PPELE183-11, CNPPE2332-12, PPELE666-11, PPELE644-11).

Prószyński (2017a) rejected Maddison’s (1996) synonymy of cursor with concolor on the basis of "lack of documentation", an extra specimen inside the type vial, and the fact that it was published in a revision of Pelegrina . However, Maddison (1996) indicated clearly the evidence that identified the holotype within the vial (by its location, labeling, and match to Banks’s description), and the features that matched the specimen to Sittacus cursor Barrows; that the nomenclatural act was published in a revision of a different salticid genus has no bearing on the validity of the act. Maddison’s synonymy, therefore, is reaffirmed here as valid.

Material examined.

U.S.A.: Florida: Gainesville (1 male, 1 female, UBC-SEM).

Figures

Figure 48. Maximum likelihood phylogeny from 757 concatenated UCE loci (average 113231 base pairs / taxon) analyzed primarily for the 23 Core Taxa in black (IQ-TREE, partitioned by locus). Topology is identical in unpartitioned analyses, with nearly identical branch lengths. Bootstrap percentage values from 1000 replicates shown for each clade. Where two numbers are shown, the first is the bootstrap percentage for the partitioned analysis, the second for the unpartitioned analysis. Where one number is shown, both analyses yielded the same percentage. An analysis of the All Taxa dataset, including the weakly-sequenced taxa in grey, yielded the same topology.
