Paroxyethira nigrispina Kelley

Figs 27, 28

Paroxyethira nigrispina Kelley, 1984: 202 , figs 30–32.

Revised diagnosis. The male ( Figs 27, 28) most closely resembles that of P. anomala , new species in having gonopods short, but in contrast the left gonopod bears a dense brush of fine setae mesally; sternite VIII bears a typical broadly spatulate process, elongate, length about 5x width at middle, whereas a very short rounded process occurs on sternite IX in P. anomala . In P. nigrispina the phallic sheath is elongate, cylindrical, twisted distally and terminating in a stout, darkly sclerotised spine and bearing a stout seta ventrally at the base of the twist and another spine at just under half length, and its basal apodeme is very short; in P. anomala the phallic sheath is short and stout.

Male antennae each with 20 flagellomeres.

Forewing length. Male 1.9 mm (n=1).

Holotype male: New Caledonia, Boulari River ( BPBM), examined.

Additional material examined: Province Sud, on road between Noumea and Yaté, 1.0 km NW Pont des Japonais, 22°11.427'S, 166°42.868'E, 113 m, 22.xi–4.xii.2003, Malaise trap, loc#039, leg. K.A. Johanson — 1 male ( SMNH) .
