( Figs 1 B–G View FIGURE 1 )
Material examined. Holotype male, CHINA: Guangdong Province, Guangzhou City, Conghua County, Wenquan Town , 16.i.2011, sweeping net, H.Q.Tang ( HBMY Type no.0005) . Paratypes: 1 male, CHINA: Guangdong Province, Guangzhou City, Yangchun County, Shiwang Town , 26.xii.2010, sweeping net, H.Q.Tang ( HBMY Type no.0004) ; 1 male, Guangzhou Province, Conghua County, Sanyatang Town , 16.i.2011, sweeping net, H.Q.Tang ( HBMY Type no.0003) .
Derivatio nominis. From Latin curva , meaning curve, referring to upcurved superior volsella.
Diagnostic characters. The male imago is separated from all the other members of the genus by the antenna with 10 flagellomeres, AR 0.65–0.72, 0.69; apex of superior volsella digitiform and upcurved, antero-medially separate, inferior volsella broad, placed caudally on gonocoxite. Phallapodeme slightly curved, joint with sternapodeme placed laterally.
Male (n=3). Total length 1.50–1.60, 1.55 mm. Wing length 0.93–1.08, 1.01 mm. Total length/wing length 1.44–1.48. Wing length/profemur length 2.86–3.05. Wing width/wing length 0.36–0.38.
Coloration. Head brown; antenna, legs and abdomen yellowish brown. Thorax dark brown.
