Subgenital plate slender with bend short ( Figs 152, 153 ). Paramere slender with a small subapical protrusion ( Figs 152, 154 ). Connective with stem nearly as long as lateral arms and central lobe distinct ( Fig. 152 ). Aedeagus with end of dorsoatrium extended; aedeagal shaft straight, lamellar ventral appendage developed with apical half digitiform and directed basad ( Figs 155, 156 ). Specimens examined. Holotype : ♂ , CHINA , Yunnan Province , Mt. Zixi , 2400m , Alnus nepalensis , 10-XI- 1999 , coll. I. Dworakowska. Paratype : 2♂ 1♀ , same data as holotype ; 1♂ , CHINA , Yunnan Province , Tengchong , volcano, 2000m , Alnus nepalensis , 23-XI-1999 , coll. I. Dworakowska ; 1♂ , CHINA , Yunnan Province , Tengchong , 1650m , 26-IV-1981 , coll. Fasheng Li. Etymology. The specific name is derived from Latin word “apiculatus which means “thin and sharp, referring to the shape of the caudal apex of the paramere ( Fig. 154 ). Notes. The new species resembles Agnesiella ( Draberiella ) sinuata , but differs in the male connective having the central lobe distinct ( Fig. 152 ), and in the aedeagal shaft without an irregularly undulate ventral margin subapically ( Fig. 155 ).
