Dinokanaga

Dinokanaga is a small genus of scorpionfly belonging to the extinct family Dinopanorpidae. The six species D. andersoni, D. dowsonae, D. hillsi, D. sternbergi, D. webbi, and D. wilsoni have all been recovered from Eocene fossil sites in British Columbia, Canada, and Washington state, United States.
"Dinokanaga" is a combination of the Greek word "deino" meaning "terrible" or "monstrous" and "okanaga" in reference to the Okanagan highlands fossil sites where the specimens have been recovered. The type description of the genus was first published in 2005 by Dr. Bruce Archibald in the "Canadian Journal of Earth Sciences". Description of the new genus was based on the study of over 20 compression fossil specimens from five fossil producing locations in the highlands. "Dinokanaga" and "Dinopanorpa", currently the only known genera in the family Dinopanorpidae, are distinguished by a number of wing vein characters including lack of fine reticulated crossveins in "Dinopanorpa", and the "Rs" vein branched 3-5 times in "Dinokanaga". The fossil specimens of high preservation quality sometimes show the original color patterning, being mostly dark with light to clear areas. Within the genus wing characters are key to separating the species.
Description.
"Dinokanaga hillsi".
"Dinokanaga hillsi", the type species, is identified by its subtriangular shaped wing which is widest at the middle, color pattern of three distinct dots, and an apical wing margin which is smoothly curved. "D. hillsi" along with "D. dowsonae" are the only two species in which part of the insects body is known, rather than just isolated wings. Though known from a number of specimens "D. hillsi" has only been found at the McAbee Fossil Beds near Cache Creek, British Columbia, and is named for Dr. Len Hills.
"Dinokanaga dowsonae".
"D. dowsonae" is identified by the penniform shape of the wings, and by the size which is larger than similar shaped wings in the other species. "D. dowsonae" is he most wide spread of the species, occurring at three different fossil sites in the Okanagan Highlands while the five other species are restricted to a single site each. This species is named in honor of Shelley Dowson, collector of one of the specimen paratypes.
"Dinokanaga andersoni".
"D. andersoni" is known from only the holotype specimen, collected and housed at the Stonerose Interpretive Center in Republic, Washington. The species is notably narrower in the preserved areas of the holotype wing then other species. The species was named in honor of Eric Anderson who first collected the type specimen in 2001.
"Dinokanaga sternbergi".
The third species found in Republic is "D. sternbergi", known from a long wing collected by Michael Sternberg in 1995, and for whom the species is named. The species is distinguished by the short length of the "Sc" vein and small size, "D. webbi" being the only species smaller in wing size.
"Dinokanaga wilsoni".
Only a single poorly preserved "D. wilsoni" hindwing has been found, but the shape is distinct enough to separate it from the other "Dinokanaga" species, being broadly a rounded oval. The sole specimen was found the Whipsaw Creek locality of the Allenby Formation near Princeton, British Columbia, and named for Dr. Mark Wilson of the University of Alberta.
"Dinokanaga webbi".
Easily distinguished from the other species, "D. webbi" is the smallest species of "Dinokanaga" with a hindwing only long and having numerous simple crossveins with only patches developing into a reticulated patterning. The type specimen was found in "Horsefly shale" outcrops along the Horsefly River near Horsefly, British Columbia, and the species named in honor of Robin Webb of British Columbia.
