Micromus pallidius ( Yang, 1987) View in CoL : Monserrat, 1990: 175. New combination.

Diagnosis. This species is characterized by the grey sagittal stripes in hyaline forewing and subcostal veinlet present; CuA not fused with MP and three gradate series present in forewing and hind wing. Male: posteroventral edge of ectoproct arm-like, covered with many tiny spines from middle to distal; extrahemigonarcus tapered distally and basal mediuncus broader and covered with many small spines; terminal lobe of parabaculum separated from one third distal. Female: subgenital developed, basally flat and distally rounded with the central slightly depressed.

Measurements. Forewing length 7.0– 9.6 mm, width 2.7–3.3mm. Hind wing length 6.0– 8.5 mm, width 2.5–3.0 mm. Body length 4–6.4 mm.

Description. Head. Yellow. Eyes dark brown. Frontogenal costa, frontoclypeal costa and pleurostomal costa obviously brown. Antenna yellow, with more than sixty segments. Labial palpus 3-segmented and maxillary palpus 5-segmented, pale yellow with brown outer edges in last segment. A subtriangular area between antennae densely covered with brown long setae in vertex.

Thorax. Yellowish-brown throughout. Pronotum and mesonotum densely covered with brown short setae. Legs yellowish-brown, with apical tarsi brown; foreleg and midleg respectively with two brown spots on tibiae.

Wings ( Fig. 3 View FIGURES 1 – 3 ). Forewing pale yellowish-brown, hyaline with grey sagittal stripes. Veins yellow, dark colored in the origins of all Rs from R vein and the gradate series. Subcostal veinlet developed with 5–6 costal crossveins. Anterior radial trace bearing 7 ORB’s; all simple. MA simple and MP forked into two branches before outer gradate series. CuA simple and not fused with MP, just linked by a short crossvein. Three gradate series, inner gradate series 4 crossveins; middle 8 and outer 10. Hind wing pale yellowish-brown, hyaline and immaculate. Veins yellow, only parts of middle gradate series and all outer gradate series brown. Rs with 7 branches. M proximally forked into 2 branches. Cu simple and CuA not fused with MP. Three gradate series, inner gradate series 3 crossveins; middle 7 and outer 10.

Male terminalia ( Fig. 18 View FIGURES 18 – 25 ). 9th tergite totally fused with ectoproct, dorsal part narrow and slightly elevated. Ectoproct approximate oval from lateral view with straight hind margin, posteroventral edge of ectoproct armshaped, covered with spines from middle to distal. 9th sternite far exceeding the hind margin of ectoproct, almost equal to the length of posteroventral extension of 9th tergite. Extrahemigonarcus of gonarcus ( Fig. 19–20 View FIGURES 18 – 25 ) developed, tapered distally and approximately slender triangle from dorsal view; basal mediuncus broader and densely covered spines, bend downward from middle part and tapered distally with recurved hook. Terminal lobe of parabaculum ( Fig. 21–22 View FIGURES 18 – 25 ) separated from one third distal, and with a small upward hook in the end. Hypandrium internum ( Fig. 23 View FIGURES 18 – 25 ) trapezoidal, with both sides slightly rolled.

Female terminalia ( Fig. 24–25 View FIGURES 18 – 25 ). 8th tergite dorsally broad and ventrally narrow, approximate subtriangle from lateral view. 9th tergite totally fused with ectoproct and ectoproct approximate trapezoidal from lateral view. Subgenital developed, basally flat and distally rounded with the central slightly depressed.

Distribution. China (Tibet, Guizhou)

Material examined. CHINA: 1♀, Tibet, Zhangmu. 20.vii.1984, Yongxiang Zhao (Holotype) ( CAU); 1♂, Guizhou province, Zunyi city, Suiyang county, Kuankuoshui. 8.vi.2010, Ruie Nie ( CAU); 1♀, Tibet, Linzhi county, Pailong. 5.xi.2007, [no collector data], ( CAU).

Remarks. This species was described in 1987 only from one female specimen. In this paper, we first describe the male specimen and provide the distribution of the species in China. This species is similar to M. yunnanus and M. setulosus sp. nov., while considering the almost immaculate membrane in forewing and veins without any setae, it can be easily distinguished.
