Pseudohy- dryphantes Hydrachna Group 2 Group 1 Fig. 53 Similarity relationships among the genera of Group 3. distolateral border of the proximal chamber with its extension into the lateral wall of the EC, sclerotized lateral chambers, and a slight reduction of the distal arms. The first and last of these features indicates similarity to Lebertia. Sperchon and Sperchonopsis are closely similar and share so many features that their species would perhaps be considered congeneric on the basis of EC characters alone. They are like Lebertia in having the midsection of the EC inflated and well sclerotized. Other similarities to Lebertia include the form of the proximal horns and the sclerite-complex formed by the anterior margin sclerite, distolateral border, and lateral wall sclerite of the proximal chamber. In addition, Sperchon and Sperchonopsis 67
