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 : 652

THE CIRCULAROIDES GROUP

Diagnosis: Small sized psocids, length of forewing c. 2 mm. Forewing ( Fig. 1A–C ), not extensively covered with small spots (secondary reversal); cell a with single marking; opposing spots in cell r absent; Rs fork acute; 3rd section of CuA almost straight, directed posteriorly. Male terminalia ( Fig. 2 ): No clunial arm. Epiproct with well-expanded lobe. Paraproctal distal lobe small; distal process almost straight. Eighth venter with pair of small sclerites widely separated from hypandrium. Hypandrium asymmetrical, with lobe-like projection on right side (= modified right process), medially with wide membranous region; left process well developed; median tongue absent. Phallosome asymmetrical, broadened posteriorly, with weakly sclerotized parameres (sensu Yoshizawa, 1998; Yoshizawa, 2004; not Yoshizawa, 2001), postero-lateral corner with extension. Female genitalia: Ventral valve of gonapophyses short, not reaching external valve. External valve lacking posterior lobe. Internal plate little sclerotized.

Remarks: Although Yoshizawa (2001) assigned the parthenogenetic T. circularoides to the spiniserrulum
