Yoshizawa, Kazunori, Aldrete, Alfonso Neri García & Mockford, Edward L., 2008, Systematics and biogeography of the New World species of Trichadenotecnum Enderlein (Insecta: Psocodea: ‘ Psocoptera’: Psocidae), Zoological Journal of the Linnean Society 153 (4), pp. 651-723 : 662

TRICHADENOTECNUM DESOLATUM (CHAPMAN)

Psocus desolatus Chapman, 1930: 236 . Trichadenotecnum (Trichadenopsocus) desolatum: Roesler, 1943: 4 .

Material examined: USA: 2 males, 2 females, New Mexico, Lincoln Co., Capitan Gap, Road #56, N. Hwy. 380, E. Capitan, 11.viii.1983, ELM ( ISU) ; 1 male, Arizona, Chiricahua Mountains , Turkey Creek, 24.viii.2004, KY ( SEHU) ; 1 female, Arizona, Rucker Canyon, 30.viii.2004, KY ( SEHU) .

Diagnosis: This species can be distinguished from the other species of this group by the combination of the following character states of the hypandrium ( Fig. 6C ): median tongue parallel sided or narrowing apically, with apparent apical notch; left process longer or almost of equal length to right process.

Remarks: Although this species can be characterized by the combination of the above mentioned character states, intraspecific variation is considerable, especially in the shape of the hypandrial median tongue. As mentioned in remarks under the group diagnosis, molecular and morphological examinations based on extensive sampling are required to test its taxonomic status.
