It belongs to the Siphonella genus group (Kanmiya 1983), with the following characters: head much wider than long; face concave, with a linear median carina; gena narrow; frons speckled, thickly clothed with short setulae, and sparsely microtomentose universally or in reticular-form; scutum as long as wide, convex, minutely or weakly shagreened, glossy or entirely microtomentose in both sexes; male surstylus highly specialized, incrassate
and semi-globose, larger than epandrium in lateral view; gonites not well demarcated; hypandrium closed (Sabrosky 1980; Kanmiya 1983; Merz 2008).
