The gonocoxites of D. barbata are quite unlike that of all other Dicerura in having an extremely large emargination ventrally, which leaves just a short, asetose intercoxal bridge; the emargination is partly filled with an ovate, microtrichose lobe (Fig. 11, ↓1). The large, subtriangular gonocoxal processes are densely microtrichose medially; the dorsal apodemes are conspicuously long and thin (Fig. 11, ↓2). The elongate gonostylus has a small side lobe subapicomedially, which is covered apically and dorsally with dense, large microtrichia, a few setulae, and 1–2 short bristles (Fig. 10, ↓3). The apical fork of the ejaculatory apodeme is perfectly V-shaped (Fig. 12). The elongate, parallel-sided tegmen, which is membranous for the most part, has a broadly rounded apex and a single pair of small, sclerotized processes subapicolaterally (Fig. 12, ↓4). The apex of the ninth tergite is bilobed and densely covered with short, thick microtrichia, especially along the edge and on the inside (Fig. 9). Remarks.
