Tipula (Emodotipula) alexanderi Men , sp. nov. ( Figs 31–47 )

Diagnosis. Body is generally brown in coloration. Head has a narrowed brown occipital stripe. Prescutum is brown with four black stripes, all stripes with darker margins. Wings have grayish-white ground color with cells c and sc slightly brown. Stigma is dark brown. Abdominal tergites are brown, narrowly variegated by black stripes on lateral margins. Tergite nine has a U-shaped notch medially, sternite nine is produced into finger-like processes in lateral angles.

Description. Male body length 12.0 mm, wing 18.4mm, antenna 3.5 mm.

Head. Rostrum brown with nasus dark brown. Antennae with scape elongated, yellowish, expanded apically; pedicel very short, pot-shaped, light brown; flagellum brown, each flagellomere subequal in length. Palpi with first segment brownish-black, the outer three segments somewhat paler. Head yellowish-brown, occipital mark brown, narrow, surrounded by paler halo ( Fig. 31 ).

Thorax. Pronotum brown, darker medially ( Fig. 32 ). Prescutum brown with four black stripes, all stripes with darker margins ( Fig. 32 ). The median two slightly concaved inward near apex ( Fig. 32 ). Scutum brown, lobes with two subtriangular black spots which connected to each other ( Fig. 32 ). Scutellum brown, median area paler ( Fig. 32 ). Postnotum brown with a black median stripe ( Fig. 32 ). Pleura yellowish-brown, with ventral margin of anepisternum and katepisternum darker ( Fig. 33 ). Halteres with stem yellowish-brown, knob dark brown. Legs with coxae and trochanters yellowish-brown; femora brown with dark brown apex; tibiae and tarsi dark brown. Wing with ground color grayish-white, cells c and sc slightly brown, stigma dark brown, gray areas dispersedly on base of Rs, distal end of R 1+2, distal margins of cells r and m and along R 4+5 and r-m ( Fig. 34 ). Venation Rs elongated, distinctly shorter than R 3, petiole of cell m 1 shorter than discal cell ( Fig. 34 ).

Abdomen. Abdominal tergites brown, narrowly variegated by black stripes on lateral margins, first tergite covered with a dark brown spot near posterior margin, second tergite with a dark brown spot, which connected to each other, forming a spindle-shaped mark, tergites seven and eight wholly dark brown ( Fig. 35 ). Sternites uniformly brown. Hypopygium dark brown ( Fig. 36 ). Tergite nine with a U-shaped notch medially, numerous nail-like points arising from the margin of notch, a pair of prominences generated form posterior margin, which densely equipped with small black setae ( Fig. 38 ). Sternite nine produced into finger-like processes in lateral angles, which rounded apically and densely covered with long hairs, with a median prominence which truncated at apex and densely covered with short straight hairs, the short hairs arranged in trapezoid on the median area of sternite nine ( Figs 39–40 ). Inner gonostylus terminated into angular end, curved apically, base area protruding with a lobe on inner side ( Figs 41–42 ). Outer gonostylus slightly curved, densely covered with black teeth and extending to the median area of inner gonostylus, with some longer and slenderer setae on lateral side ( Fig. 43 ).

Semen pump with compressor apodeme fan-shaped, each lateral angle rounded ( Fig. 45 ). Posterior immovable apodeme curved dorsally, very acute apically, slightly longer than compressor apodeme ( Fig. 44 ). Anterior immovable apodeme with arms very short, acute apically ( Fig. 44 ). Aedeagus slender, at least 4.0 times longer than semen pump ( Fig. 44 ).

Female body length 13.0 mm, wing 20.4 mm, antenna 3.0 mm.

Colors of head and thorax similar to those of male.

Abdomen yellowish-brown, tergites with median and lateral stripes, tergite six almost wholly variegated with black, tergites seven to ten wholly black ( Fig. 37 ). Sternite yellowish-brown with lateral stripes black ( Fig. 37 ). Ovipositor black ( Figs 46–47 ). Cerci short, gradually narrowed to apex ( Figs 46–47 ). Hypovalva very small, triangular, rounded apically ( Figs 46–47 ).

Material examined. Holotype. ♂. China, Anhui, Yaoluoping National Nature Reserve, Yaoluoping Village (30°59'N, 116°04'E), 26 Aug. 2016, coll. Qiulei Men. Paratype. 1♀, same data as holotype .

Etymology. The specific epithet is a noun after the name of Charles P. Alexander, the famous crane flies researcher, for commemorating his excellent work.

Remarks. The new species is mostly similar to the species Tipula (Emodotipula) lishanensis Young, 2014 from Taiwan, China, in the colors of body and wing, the sternite nine with two elongated lobes and the shape of inner gonostylus. It can be easily separated from the latter by posterior margin of tergite nine without a pair of finger-shaped processes medially and without sacculi laterales as illustrated in Figure 38 (with such processes and sacculi laterals in relative species as described by Young, 2014: 234), by the shape of outer gonostylus which slightly curved not boomerang-shaped (as a boomerangshaped blade in relative species as described by Young, 2014: 234).

Distribution. China (Anhui).
