( Figs 1–2 , 11 A–E)

Cortona minuta Oman, 1938: 390 .

Length. Male: 2.1–2.3 mm (n=4); female: 2.8–3.0 mm (n=3).

Morphology. Crown longer than distance between eyes ( Fig. 1 A–B). Male anteclypeus distinctly tapered distally ( Fig. 1 E).

Male genitalia. Subgenital plate short, lateral margin distinctly concave ( Fig. 2 D). Style with articulating arm long; preapical lobe angulate; apophysis short, strongly laterally curved ( Fig. 2 E). Connective shorter than aedeagus. Aedeagus broadly and deeply bifid apically, with pair of slender appendages directed apicad on dorsal surface, curved away from each other and not extended to shaft apex, distal depressed portion of shaft with pair of small lateral teeth directed basad subapically ( Fig. 2 F–H).

Female abdomen. Sternite VII with median lobe overlapping slightly more than half total width of posterior margin, trilobed, median lobe acutely pointed and slightly longer and narrower than lateral lobes, darkly pigmented ( Fig. 11 E).
