Cosmetus albolineatus Sorensen 1884

[3] The northernmost cosmetid (albolineatus) Only five years after Simon had named Cynorta sayi, Sørensen (1884) baptized a third American cosmetid – Cosmetus albolineatus Sørensen, 1884 from New Orleans, Louisiana. Sørensen’s lengthy Latin description is enough to allow recognition of this species (Fig. 2d). By then, the recognition of three USA species was clear enough, so that Weed (1893) also transferred albolineatus to Cynorta and easily summarized the distinction of the three American species of Cynorta. Weed offered redescriptions of those Cynorta, providing some additional records – in the case of C. sayi he also mentioned a distinct morph (see [7]) with a “yellow marking on dorso-meson behind eye eminence, and a transverse line near posterior margin of abdominal scutum.” In the case of C. albolineata, he also provided illustrations which match precisely Sørensen’s description and also considerably expanded the known distribution of the species. As for C. ornata, Weed described the variation of the “canary-yellow” markings and noted it as “exceedingly abundant in the pine woods under logs.”
