(Zehntner, 1894)
A female specimen before me well agrees with the diagnosis and figures given by Zehntner and Tesch, but it probably belongs to Viaderiana, not to Litocheira, for the front is medially notched and bilobate, each lobe being convex and marked on lateral angle by an indistinct lobule (which, however is not exactly represented in Zehntner's figure), and is separated from the supraorbital border; in true Litocheira, the the front is truncate and entire, by no means notched in the middle nor on either lateral side. No ridge that define the efferent branchial channel, while in true Litocheira they may be present.
A transverse ridge of longish hairs just above and along the edge of the frontal margins and a narrower similar ridge in front of the protogastric region. The superior orbital border has two distinct notches, while the inner infraorbital angle is round and not toothed. There are two slender and acuminate spines on each antero-lateral border, while the external orbital angle is ill-developed. Merus of ambulatory legs is characterized in having a few or several spinules; carpus and propodus are more thickly haired. (T. Sakai, 1939: 541)
