Scale bars: 0.1 mm. Thorax width 0.98 mm , mainly yellowish with 3 indistinct brown stripes; scutellum, anepisternum and katepisternum yellowish; prescutellar seta absent; 1 postpronotal seta, 2 notopleural setae, 1 postsutural supra-alar seta, 1 + 2 dorsocentral setae, dark brown, the last long; intra-alar seta absent, 2 postalar setae, dark brown; 1 lateral scutellar seta, 1 apical scutellar seta, strong; 1 anepisternum seta, 1 katepisternal seta. Legs light yellow with tibiae brown. Wing (Fig. 20 ) clouded on distal 2 / 5, becoming darker anteriorly, and around middle of M 1 ; M 1 ratio 6; halter white. Abdomen dark yellow and white; setae and setulae brown. Male genitalia (Figs 21–24 ): epandrium height and width subequal in length. Cerci very small, outline almost that of equilateral triangle, not separated, height 0.9 times width. Surstylus 0.4 times length of epandrium, with many small setae on inner and outer surfaces, apex without spines. Pregonite with 4 medial setae, lacking any other smaller setae or setulae. Distiphallus short, membranous. Female. Unknown. Distribution. China ( Yunnan ). Etymology. The specific name “ flavida ” refers to the colour of this species, which is mostly pale yellow. Remarks. The new species is similar to H. plumosa (Sasakawa) , but it differs in having a yellowish head, indistinct stripes on the scutum, and fully fused cerci. In H. plumosa (Sasakawa) , the head is yellow, the thorax is more distinctly striped, and the cerci are separated ( Sueyoshi 2006 ).
