Male pygofer side with 2 bands of fine setae longitudinally on medial side of triangular sclerotized band; a long digitiform appendage arising from posteroventral margin and directed dorsad ( Figs 176, 177 ). Subgenital plate with stipitiform protrusion bearing 3 peg-like setae apically ( Figs 178, 179 ). Paramere with caudal apex sharp and thin, subapical protrusion small ( Figs 178, 180 ). Connective with stem shorter than lateral arms and central lobe absent ( Fig. 178 ). Aedeagal shaft slender with lamellar dorsal subapical extension subtriangular, ventral appendage with apex long, digitiform and pointing to apex of shaft ( Figs 181, 182 ).

Specimens examined. Holotype: ♂, CHINA, Guizhou Province, Guiyang , 1000m, 25-V-1981, coll. Fasheng Li. Paratype: 1♂ 3♀, same data as holotype .

Etymology. The specific name is derived from Latin word “stipitatus which means “petiolate, referring to the handle-like subapical protrusion of the subgenital plate ( Fig. 179 ).

Notes. The new species resembles Agnesiella (Draberiella) lata sp. nov., but differs in the male pygofer side with a longer appendage ( Fig. 177 ), in the subgenital plate with a stipitiform subapical protrusion bearing 3 peg-like setae ( Fig. 179 ), and in the aedeagal shaft not narrowed subapically in posterior view ( Fig. 182 ) with the apical part of the ventral appendage longer ( Fig. 181 ).
