Figs 179–186 Type material. Holotype male ( SMF ), India , Himachal Pradesh , Shimla , University Campus , N 31°6.8' , E 77°8.5' , 2000–2200 m altitude, Y.M. Marusik leg. 25.–27.V.1999 . Etymology. This species is named in honour of my secondary school maths and physics teacher, Klaus Beyersdorf (Paderborn, Germany ), for his patience with a class of children (Sexta to Quarta) and his excellent teaching; name in genitive case. Diagnosis. Small Ctenidae (total length male 5.8). Male palp ( Figs 180–183 ) similar to that of A. torbjorni Raven & Gray 2001 in having a prolateral extension on the proximal cymbium and a transverse elongated tegular apophysis arising subproximally from the tegulum (arising centrally in other Asian species). Distinguished from A. torbjorni by (1) the shorter cymbial tip, (2) the spiky prolateral end of the tegular apophysis, (3) the RTA arising FIGURE 179.
