Type material.

Holotype female (NMNH) labelled " Gonatocerus kootenai   Huber Holotype female #543761".


Female. Colour dark brown except pedicel laterally, pronotum, trochanters, base and apex of femora, base and apex of tibiae (at least of fore and middle legs) and tarsomeres except apical tarsomere of all legs whitish. Holotype (Fig. 9) measurements as follows. Body length 1270. Head height 246, length 157. Antenna (Fig. 10) with total funicle length 476; scape -, pedicel 57, fl1 54, fl2 57, fl3 52, fl4 59, fl5 69, fl6 64, fl7 61, fl8 60, clava 120. Mesosoma length 462. Fore wing length 1101, width 309, length/width 3.56, venation length 259, longest marginal setae 95. Hind wing length 729, width 35, longest marginal setae 67. Metasoma (Fig. 11) length 658. Ovipositor length 588.


Gonatocerus kootenai   differs from the following two species by the relatively narrower wings and shorter funicle segments. I tentatively place it in Gonatocerus (Gonatocerus)   because of the relatively narrow fore wing and fairly long and relatively slender fl3-fl5. The reverse side of the shale piece contains a specimen of Trichoptera   .

Derivation of species name.

Named after the Kootenai tribe of the Flathead Nation in northwestern Montana, site of the Kishenehn shales.
