status

sp. nov.

Paroxyethira koegi , new species

Figs 6–9

Superficially very similar to P. dumagnes , but males distinguished by the spine on the phallic apparatus, more asymmetric gonopods, and elongate phallic sheath.

Male antennae each with 20–21 flagellomeres.

Forewing length. Male 1.8–1.9 mm (n=5).

Male genitalia ( Figs 6–9). Short sharp spur present medially on abdominal sternite VII. Median process on abdominal sternite VIII stoutly spatulate, length about 5 times width at 1/2 length. Abdominal sternite and tergite IX fused, laterally only slightly produced posteriorly, dorsally deeply concave. Gonopods inserted asymmetrically; right well to left of centre; both bearing brushes of stout black setae. Phallic apparatus ( Fig. 9) slender, elongate, constricted at 1/4 length at which constriction arises short, threadlike titillator; short sharp spine at about 2/3 length. Phallic sheath ( Fig. 8) short, broad at base; extended posteriorly as elongate, curving sheath, about 1/2 length of gonopods, with setae apically; basal structures difficult to interpret.

Female not associated with certainty.
