Subgenital plate with outer margin sclerotized except at end ( Figs 161, 162 ). Paramere with subapical protrusion small ( Figs 161, 163 ). Connective with stem longer than lateral arms and central lobe absent ( Fig. 161 ). Aedeagal shaft straight with apex extended ventrally and ventral margin undulate subapically, ventral appendage with 2 digitiform branches respectively directed upwards and downwards in lateral view ( Figs 164, 165 ). Specimens examined. Holotype : ♂ , CHINA , Yunnan Province , Xinzhu , 2250m , Alnus nepalensis , 15-XI-1999 , coll. I. Dworakowska. Paratype : 2♂ 1♀ , same data as holotype ; 1♂ , CHINA , Yunnan Province , Jinping , 1600m , 11- V-1956 , coll. Keren Huang ; 2♀ , CHINA , Yunnan Province , Xinzhu , 2300m , Alnus nepalensis , 16-XI-1999 , coll. I. Dworakowska. Etymology. The specific name is derived from Latin compound word “tridigitatus, referring to the trifurcate pygofer appendage ( Fig. 160 ). Notes. The new species resembles Agnesiella ( Draberiella ) fatima , but differs in the male pygofer side with a trifurcate appendage ( Fig. 160 ), in the aedeagal shaft with an undulate ventral margin subapically and in ventral appendage with only 2 digitiform branches forming an arch in lateral view ( Fig. 164 ).
