All paratypes bear the following label: ‘ PARATYPE [yellow] J, Tipula (Emodotipula) yaoluopingensis sp. n. Men det., 2013’.

Diagnosis. Antenna with scape and pedicel light yellow, flagellum blackish brown; prescutum gray with four dark gray stripes; wings subhyaline, R 1+2 entire, petiole of cell m 1 distinctly shorter than discal cell; abdominal tergites with lateral and median dark stripes, sternites uniformly yellow, hypopygium brownish black; tergite nine with two finger-shaped processes at hind margin medially.

Description. Male (n = 3). Body length 13.2–13.4 mm, wing 16.5–16.7 mm, antenna 4.6–4.8 mm.

Rostrum yellow with lateral sides blackish brown, nasus light yellow, palpi dark brown, surface of rostrum densely covered with black setae. Antenna relatively long, bent backward extending to first abdominal segment, scape and pedicel light yellow, flagellum blackish brown, verticils black, slightly shorter than coordinate segments. Head yellow, vertex with median stripe, gradually narrowed directed cephad.

Pronotum grey with one median and two lateral brown areas. Prescutum ( Fig. 4 ) grey with four dark grey stripes, median two narrowly separated by greyish line in middle, connected apically; lateral stripes bordered by black on inner margins. Scutum grey, each lobe with two dark grey areas. Scutellum and postnotum dark grey with black median line. Pleura brownish grey, variegated by dark brown on anepisternum, meron, and ventral half of katepisternum. Halter with stem yellow, knob dark brown. Legs with coxae and trochanters yellow, femora yellow with black tips; tibiae and tarsi dark brown. Wings ( Fig. 1 ) subhyaline, cells c and sc slightly darker than ground color; stigma black; Rs slightly tinged with dark brown at branch point, wing-apex and outer margin of wing suffused with dark brown, R 3, branch point of Rs, r-m, m-m, petiole of cell m 1, branch point of CuA, and middle point of A 1 suffused with dark brown as illustrated in Figure 1 . Venation: Rs relatively long, curved in basal two fifths, R

1+2

entire, discal cell relatively broad, petiole of cell m

1

distinctly shorter than discal cell.

Abdomen yellow, tergites with lateral and median dark stripes, sternites uniformly yellow, hypopygium brownish black. Hypopygium with tergite nine and sternite nine fused ( Figs 5–6 ); sternite eight relatively widened in lateral view, produced into a rounded apex medially, slightly sunken in lateral angles ( Figs 6–7 ); tergite nine with narrow notch medially, apically divided into two finger-like processes, densely covered with blackened spinulae at apex, many long hairs located on surface of tergite nine ( Figs 5–6 ); outer gonostylus boomerang-shaped, apically covered with blackened spinulae, with a row of blackened spinulae on ventral side ( Figs 5, 8–9 ); inner gonostylus with two black beaks on ventral and dorsal sides, near dorsal beak with small black spinous process, near ventral beak with cone-shaped process, lobe projecting from ventral margin densely covered with long hairs ( Fig. 10 ); aedeagal guide bell-shaped ( Fig. 11 ); aedeagus elongate, slender, acute apically ( Fig. 12 ).

Semen pump with compressor apodeme fan-shaped, slightly depressed medially, with ridge in the middle, forming 90° angle with posterior immovable apodeme ( Figs 12–13 ). Posterior immovable apodeme distinctly longer than compressor apodeme, gradually narrowed to apex in lateral view ( Fig. 12 ). Anterior immovable apodeme gradually narrowed to apex ( Fig. 12 ).

Female. Unknown.

Differential diagnosis. Tipula (Emodotipula) yaoluopingensis is the second species in this subgenus recorded in Mainland China. The new species was compared to another species, T. (E.) multisetosa , from mainland China and several other related regional species based on published descriptions and illustrations, and it is mostly similar to the Indian species Tipula (Emodotipula) hemmingseni Alexander, 1968 in the colors of body and legs, the boomerang- -shaped outer gonostylus, and the similar arrangement of beaks on inner gonostylus. It can be easily separated from the latter by hind margin of tergite nine with a pair of finger-shaped processes medially and without cushion as illustrated in Figure 5 (tergite nine with a pair of bifid processes, more ventrally with a pair of lateral blackened cushions in T. (E.) hemmingseni as described by ALEXANDER 1968: 358).

Etymology. The specific epithet is an adjective composed of the noun ‘ yaoluoping ’ with Latin suffix ‘- ensis ’, referring to the type locality of this new species.

Distribution. China (Anhui) based on current records.
