Scutum brownish with triangles brown. Scutellum with basal half brownish and distal half dark brown ( Fig. 11 ). Forewing yellowish with 2 brownish patches on clavus, one at base and the other near center of commissural margin; a broad brownish band extended from base of corium to cross vein along MP longitudinal vein; brochosome field brownish ( Fig. 80 ).

Abdominal apodemes nearly reaching end of 5th abdominal sternite. Posterior margin of male pygofer side with a short horn-like appendage bearing a few rigid microsetae, a longitudinally banded sclerite tuberculate terminally and directed cephalad from its lower end ( Figs 81, 82 ). Subgenital plate with some fine setae terminally ( Fig. 84 ). Paramere with caudal part thickened subapically and bent laterad nearly at right angle, subapical protrusion absent ( Fig. 85 ). Connective with stem nearly three times long as lateral arms and central lobe indistinct ( Fig. 86 ).Aedeagal shaft arched and slightly expanded dorsally near middle, with an arched dorsal extension subapically and a narrow ridged ventral appendage approximately on apical 1/4 ( Figs 87, 88 ).

Specimens examined. Holotype: ♂, CHINA, Hunan Province, Mt. Hengshan , 30-VIII-1980, coll. Xinwang Tong. Paratype: 1♂, CHINA, Hunan Province, Sangzhi , 6-IX-1981, coll. Xinwang Tong ; 1♂, CHINA, Hunan Prov- ince, Chenzhou , 27-VII-1985, coll. Yalin Zhang and Xinwang Tong ; 1♂, CHINA, Hunan Province, Sangzhi, Mt. Tianping , 1250m, 14-VIII-2001, coll. Qiang Sun.

Etymology. The specific name is derived from Latin word “recurvus, referring to the terminally recurved longitudinal sclerite on the posterior margin of the pygofer side ( Figs 81, 82 ).

Notes. The new species resembles Agnesiella (A.) polita sp. nov., but differs in the male pygofer side with rigid microsetae on a horn-like appendage and the tuberculate end of the ventral appendage ( Figs 81, 82 ), and in the aedeagal shaft with a shorter ridged ventral appendage ( Fig. 87 ).
