Male pygofer side with 2 bands of fine moderate setae near posterior margin, and a short horn-like appendage directed dorsad on posterior margin ( Figs 115, 116 ). Subgenital plate with some long fine setae terminally on outer side, and a small protrusion at narrowing subapical part ( Figs 117, 118 ). Paramere slender with subapical protrusion small ( Figs 117, 119 ). Connective with stem nearly as long as lateral arms and central lobe indistinct ( Fig. 117 ). Aedeagal shaft slender with a small lamellar ventral extension terminally, a trifurcate ventral appendage near basal 1/3 with 2 branches directed upwards and shortest lower branch directed downwards ( Figs 120, 121 ).

Specimens examined. Holotype: ♂, CHINA, Sichuan Province, Moxi , 1600m, Alnus nepalensis , 4-XI-1999, coll. I. Dworakowska. Paratype: 1♂, same data as holotype ; 3♂ 1♀, CHINA, Sichuan Province, Moxi , 1600m, Alnus nepalensis , 5-XI-1999, coll. I. Dworakowska ; 1♂, CHINA, Sichuan Province, Moxi , 1650m, Alnus nepalensis , 5- XI-1999, coll. I. Dworakowska.

Etymology. The specific name is derived from Latin compound word “longisagittata which means “long arrow, referring to the long arrow-shaped caudal end of the paramere ( Fig. 119 ).

Notes. The new species resembles Agnesiella (Draberiella) savita , but differs in the aedeagal shaft with branches of the ventral appendage straighter and all branches arising from a common stem ( Fig. 120 ).
