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 : 703

THE SLOSSONAE GROUP

Diagnosis: Forewing ( Fig. 36C–F ) not extensively covered with small spots; Rs fork obtuse; 3rd section of CuA more or less arched. Male terminalia. Eighth venter with large transverse sclerite broadly fused with hypandrium. Clunial arm ( Fig. 38A ) well developed, long and broad, with rounded and serrate distal margin, forming free process apically. Epiproct ( Fig. 38B ) with pair of projections on postero-dorsal margin; epiproct lobe well developed, protruded over clunium, variable in shape ( Figs 38B , 40B , 41B , 42B ). Paraproct ( Fig. 38A ): ventro-lateral band short, almost indistinct; distal process long, directed upward. Eighth venter ( Fig. 38C ) with single transversal sclerite. Hypandrium ( Fig. 38C ) symmetrical, postero-median region broadly membranous, dorsally with sclerotized flaps; left and right processes well developed, long and needle-like (except for T. simile ), more or less hooked. Median tongue membranous, very narrow and long. Phallosome ( Fig. 38D ) with pair of small processes posteriorly, processes sometimes fused to single process ( Fig. 41D ). Female genitalia. Dorsal surface of egg guide of subgenital plate ( Fig. 39A ) with median sclerite. Dorsal valve of gonapophyses ( Fig. 39B ) with short distal process; posterior lobe of external valve not strongly projected. Internal plate ( Fig. 39C ) symmetrical, broadly sclerotized and pigmented, strongly pigmented around spermathecal opening, posteriorly with square-shaped extension.
