Remarks. Males of Kongsbergia reticulata differ from those of K. cooki sp. nov. in that the ridges on the dorsal shield are more prominent and the dorsal hump is higher, and the color pattern is usually more intense. They differ from males of K. labyrintha in that the dorsal shield is more rounded, the ridges on the shield are less strongly developed and the reticulate sculpturing is less extensive and less regular. They differ from males of K. crumpae sp. nov. in that the ridges on the dorsal shield are more developed and the tibia of the pedipalp lacks a prominent proximoventral projection.

Kongsbergia reticulata is the most widespread and commonly collected species of the genus in eastern Canada and the northeastern United States. The populations from Mississippi differ from other members of K. reticulata in that they are deeply pigmented with purple patches anteriorly and posteriorly and an additional medial orange area at the anterior edge of posterior purple patch. The population in the Torch River in central Saskatchewan is geographically widely separated from other known populations but adults exhibit morphological character states that are typical for members of K. reticulata .
