(Figs 249–259)
Diagnosis. Wing with basal edges of brown apical spots on R2+3, R4+5 and M1 behind vertical level of brown stripe on dm-cu, forming ladder-like slope; a small round spot on R4+5, nearly middle point of distance between r-m and dm-cu; brown stripe over dm-cu with brown spot on upper margin larger than that on lower margin; subcostal cell pale brown. Male genitalia: reverse U-shaped pregonite with two arms asymmetrical distinctly and postgonite with a short process; aedeagus with a pair of lateral teeth subapically in ventral view

Frons brownish yellow except for pale yellow anterior marign, as long as wide; ocellar triangle yellow; oc developed, longer than anterior or; anterior or slightly shorter than posterior or; gena about 1/5 height of eye. Antenna yellow, 1st flagellomere pale grayish brown on apical 1/3 (only one present, another one broken); 1st flagellomere 2.0 times longer than height; arista dark except for brownish basally, ray short plumose with longest ray slightly shorter than height of 1st flagellomere. Proboscis and palpus yellow.

Wing (Fig. 254) pale yellow, basal edges of brown apical spots on R2+3, R4+5 and M1 behind vertical level of brown stripe on dm-cu, forming ladder-like slope; a small round spot on R4+5, nearly middle point of distance between r-m and dm-cu; brown apical spots on R2+3 and R4+5 confluent, apical spot on M1 separated from that on R4+5; brown stripe over dm-cu with brown spot on upper margin larger than that on lower margin; subcostal cell pale brown; costa with 2nd (between R1 and R2+3), 3rd (between R2+3 and R4+5) and 4th (between R4+5 and M1) sections in proportion of 5.2:1.3:1; r-m before middle of discal cell; ultimate and penultimate sections of M 1 in proportion of 1:1.6; ultimate section of CuA1 about 1/7 of penultimate. Halter yellow.
