2. Pseudoplectus ? sp. 1 ( Figs. 3B–C , 4 )

Specimens examined. 1 male, Nr. Summit, St. A, alt. ca 1,900 m, by SWA, 22. viii .; 2 females, W mine, St. B, alt. 1,672 m, by SWA, 20. viii .

Remarks. This genus is characterized by the very small and elongate body. After the SEM obserbation, the male and the female characters were examined as shown in Fig. 4 . The male is easily distinguished from the female by the sexual patch laid on the frons and the strongly thickened mid femur. The male eyes are clearly larger than those of the females. In both sexes, the pronotum is rounded on both sides, with a pair of basilateral and a basimedian fovea, and a pair of short sulci connecting basilateral and basimedian foveae.
