and the 2 are not likely to be confused. The angular process on the dorsal lobe of the inferior appendage, as figured and mentioned in the original species description by Denning and Sykora, is somewhat misleading as a diagnostic character. The dorsal lobe of the inferior appendage is actually broadly rounded, as in other members of the

This character, while evident in the type specimen, is not generally characteristic of the species. The apparent absence of a mesal lobe of tergum X (in material examined) is unusual for species in the

Segment IX very short, with elongate setae along posterolateral margin. Tergum X with mesal lobe absent (in specimens examined), but with short, paired lateral membranous projections (not figured). Preanal appendage moderately elongate, length about 4 times maximum width, simple in structure, some apical setae elongate. Inferior appendage with prominent rounded dorsal lobe and weakly projecting ventral lobe; dorsal lobe with posterior margin distinctly, but rather weakly, mesally incurved; projection of ventral lobe rounded apically, obtusely angled; ventral margins of ventral lobes, as viewed ventrally (Fig. 9F), not diverging at base, rounded

Phallic shield, surrounding phallobase, very distinctly sclerotized. Phallobase relatively short, strongly ventrally curved at about middle, apex distinctly sclerotized; ventral apex, as viewed caudally, broadly U-shaped. Phallotremal sclerite prominent, basally forming short tubular collar, ventral margin projecting, apex acute; asymmetrical lateral sclerite absent.
