Agnesiella (D.) lata Huang & Zhang sp. nov.

( Figs 50, 53, 56, 59 , 166–174 )

Measurement. Male, 3.25 mm (including wings).

Body brownish ( Figs 50, 53 ). Face with brownish transverse streaks on yellow ochre frontoclypeal area, most of remaining part black-brown ( Fig. 59 ). Vertex reddish-brown near coronal suture. Pronotum with 5 patches blackbrown and central area near posterior margin suffused with brownish. Scutellum yellow ochre with triangles brown ( Fig. 56 ). Forewing with basal half covered with smoky infuscate patches; brochosome field light ochre ( Figs 50, 53 , 166 ).

Abdominal apodemes reaching middle of 6th abdominal sternite ( Fig. 167 ). Male pygofer side with 2 bands of fine setae longitudinally on medial side of triangular sclerotized band; posteroventral margin slightly protruding with a digitiform appendage extended dorsad ( Figs 168, 169 ). Subgenital plate with a small protrusion bearing a peg-like seta apically on bend ( Figs 170, 171 ). Paramere with subapical protrusion broadened basally ( Fig. 172 ). Connective with stem slightly shorter than lateral arms and central lobe absent ( Fig. 170 ). Aedeagal shaft with arched lamellar dorsal extension subapically, ventral appendage horn-like and curved upwards ( Figs 173, 174 ).

Specimens examined. Holotype: ♂, CHINA, Yunnan Province, Xinzhu , 2250m, Alnus nepalensis , 15-XI-1999, coll. I. Dworakowska. Paratype: 1♀, same data as holotype .

Etymology. The specific name is derived from Latin word “latus which means “broad, referring to the paramere with a basally broadened subapical protrusion ( Fig. 172 ).

Notes. The new species resembles Agnesiella (Draberiella) stipitata sp. nov., but differs in the male pygofer side with a shorter appendage ( Fig. 169 ), in the subgenital plate with subapical protrusion bearing a peg-like setae ( Fig. 171 ), and in the aedeagal shaft expanded at middle then narrowed subapically in posterior view ( Fig. 174 ), with the apical part of the ventral appendage shorter ( Fig. 173 ).
