Head mostly brown, with a brown triangular originating from between posterior ocelli extending to centre of occiput. M-line brown. Antennae palpi yellow brown.

However, the epiproct of S. americana a bilobed anterior membranous area (see figs. 19–23 in Frison 1936), while in the new species, the membranous lobe is not divided. The elongate hemitergal lobe of the new species is easily distinguishable from those of other congeners. In addition, the lobe and the shape of the aedeagus are reminiscent new species of Arcynopteryx dichroa (McLachlan, 1872) . However, Skwala longiloba lacks a slender needle-like stylet of the epiproct which is present in A. dichroa (see Teslenko 2012, figs. 2 and 5).</p><p>HISTORY</p></div>	https://treatment.plazi.org/id/0397A14B5F7C5A3CFDCDFF54FAE13721	Public Domain	No known copyright restrictions apply.
