Humeri weakly silver pruinose; lateral and posterior margins of scutum black [light source anterior or posterior], weakly silver pruinose when specimens viewed at an angle. Scutellum black with recumbent golden hairs interspersed with long, erect black hairs on posterior margin. Postnotum black with silvery grey pruinosity. Wing setation as in female, except Subcosta with fewer setae. Leg coloration as in female except legs darker brown.

Gill configuration with main trunk short, giving rise to four sets of primary branches, three external and one internal (Figs 20– 21). Primary branches bifurcate farther into secondary branches that are highly variable in number of filaments, all branching at different heights. In gills with the lowest number of filaments, the configuration is as follows: most dorsal of external branch often with 17 filaments, median 8 and ventral 7; internal set of filaments often consisting of 14 filaments. Variation of this pattern occurs on all primary branches. Filaments stout, pointed, and highly sclerotised distally, edges weakly crenate; all filaments approximately same length.</paragraph>
