Atopsyche (Atopsaura) sanctipauli Flint 1974

Atopsyche sanctipauli

On the basis of the mesal position of the apical process of the basal clasper segment, this species should be placed in the longipennis group. In this group, the only species with a dorsal process on the aedeagus is the Mexican A. japoda Ross. Atopsyche sanctipauli, however, is immediately recognized by the forked lateral process of the aedeagus, the different shapes of the paracercus, and the apical parts of the claspers.

ADULT.—Length of forewing 7 mm. Color brown, legs yellowish; forewing brown, with indication of lighter and darker mottling. Male abdomen with internal pouches from anterolateral angles of third and fourth terga; fifth sternum with only a slight knob anterolaterally; posteromesal process of sixth sternum as long as sternum, that of seventh sternum two-thirds as long as sternum. Male genitalia: Ninth segment narrow laterally; tenth tergum typical. Paracercus developed into a basally directed dorsal crest, bearing a short, pointed, lateral process near base and another near apex, apical portion narrowly produced, tip upturned and bearing 3 small points. Filicercus lacking (broken off?); cercus a small, rounded lobe. Clasper with basal segment long, parallel-sided, bearing a small lobe from mesal face, apicoventral process thin, bilobed in ventromesal aspect; apical segment broad basally, apex thin, produced and curved so as to cover apicoventral process. Aedeagus with base short, bearing a nonarticulated dorsal process; lateral lobes thin, with a narrow dorsolateral flange, laterally with a thin, deeply bifurcate lobe, with a long, slender, central spine.

MATERIAL.—Holotype, male: BRAZIL, SAO PAULO: Alto da Serra, 29–30 October 1927, Zerny (Vienna).

The species described below is only the second species to be discovered in the genus. The species are known only from within the Chilean Subregion.
