22. Theognete giselae Anderson , new species ( Figures 92 , 102 , 111 )

Diagnosis. Size. Length, male, 4.27mm; female, 3.71–4.05mm. Width, male, 1.97mm; female, 1.74–2.08mm.

Geographical distribution. México (Oaxaca).

Natural history. Collected from berlese extraction of oak-pine forest and mixed pine forest leaf litter at elevations ranging from 2700–2850m.

Derivation of specific name. Through their support of the Nature Discovery Fund at the Canadian Museum of Nature, this species is named after Gisèle St-Germain of Montreal, Québec, Canada, as a gift from the Lalanne family.
