3.4 Tipulodina xyris ( Alexander, 1949) ( Figs 4 , 30–36 )

Tipula (Tipulodina) xyris Alexander, 1949 , 2: 523.

Diagnosis. Antenna relatively long, beyond the caudal margin of second abdominal segment, scape and pedicel yellowish, flagellum grayish brown with brown expanded base ( Fig. 30 ). Prescutum grayish brown with three brown stripes ( Fig. 4 ). Scutum, scutellum and postnotum grayish brown. Wings whitish and transparent, wing tip and stigma black ( Fig. 30 ). Abdominal tergites grayish brown, sternites grayish ( Fig. 30 ).

Redescription of hypopygium. Ninth tergite transverse, slightly concaved on caudal margin, with a pair of conical processes arising from the middle area ( Fig. 31 ). Sternite nine broad with a straight ventral margin in lateral view, the hind margin deeply concaved in ventral view ( Figs 32–33 ). Sternite eight extended caudad ( Fig. 32 ). Outer gonostylus broadly triangular, widened medially ( Figs 31–32, 34 ). Inner gonostylus narrowed to the tip, rod-shaped and bearing an irregular process on lateral margin ( Figs 31–34 ). Appendages of gonocoxite possessing a slender black rod and a hairy lobe, the rod equipped with many small black setae on apex and with many black teeth on lateral margin ( Fig. 34 ).

Semen pump with compressor apodeme fan-shaped, forming a 60° angle with posterior immovable apodeme ( Figs 35–36 ). Posterior immovable apodeme slightly longer than compressor apodeme, curved dorsally in lateral view ( Fig. 36 ). Anterior immovable apodeme very short, not connected apically. Aedeagus tubular and elongated, more than two times longer than semen pump, acute apically ( Fig. 36 ).
