Material examined. Type material. PARATYPES, 1 male, labeled (1) Hequ county/ (19)78. VII.17 [handwritten in Chinese]; (2) PARATYPE / Lispe lanceoseta Wang et Fan, 1980 [red label with broad margin, first line printed, second line handwritten]; (3) Hequ liuying nov. sp. [handwritten, the original but unused Chinese name of the species]; 1 female, labeled (1) Hequ county/ (19)78. VII.17 [handwritten in Chinese]; (2) PARATYPE / Lispe lanceoseta Wang et Fan, 1980 [red label with broad margin, first line printed, second line handwritten]. Both in SEMCAS.

Redescription. Male. Body length: 4.9–5.0 mm ( Fig. 20 A). Head ( Fig. 20 C): Eye bare, facet a little expanded on anterior margin in median part; frons broad on median part, becoming narrow anteriorly; frontal vitta, frontal triangle and frontal-orbital plate with obvious boundary; frontal vitta dark brown; frontal-orbital plate and frontal triangle with grey pollinosity; median part of frontal triangle about 0.3 times as wide as frontal-orbital plate, upper orbital setae 1, frontal setae 3 and with 1 row of short setae on outer part; parafacial bare, about as wide as postpedicel; facial ridge low, concave; antenna black, with greyish pollinosity, postpedicel slightly longer than pedicel, arista plumose, longest setula longer than width of postpedicel; face planate, without facial carina, epistoma not projecting; vibrissa absent; genal height about 1/10 of eye height; proboscis short, labella small; palpi big and yellow, compressed, towards apex expanded, outer surface setulose apically.

Thorax: Ground color black with dense grey pollinosity; acr 0+1 (setula-like); presutural 4–5 rows of acrostichal setulae; dc 2+3 (developed); ia 0+2; without pra; katepisternal setae 1+2.

Wings: hyaline; veins towards apex becoming more yellowish brown; vein R4+5 parallel to M1+2; calypteres white, the lower one about 2 times as long as the upper one; haltere yellowish.

Legs: Black except knees yellowish brown; with grey pollinosity; fore legs short; fore femur with sparse pv in basal 2/3; fore tibia with 1 preapical ad, first tarsomere slightly longer than other segments of tarsis; mid femur with strong av on apical 1/2; mid tibia with 1 short weak ad and 1 short weak pd in apical 1/3, with apically willowleaf-like av and pv spines ( Figs 20 B; 21C); mid tarsi greyish yellow; hind femur with av in basal 3/4; hind tibia with 1 submedian ad; first hind tarsomere short, slightly swollen, with sharp apex, equal to summed length of other tarsomeres, with dense and curved bristles on the anterior dorsal margin ( Figs. 1 G; 21D).

Abdomen ( Fig. 20 D): Ground color black, oval; tergites 3–5 dusted with brown patches on anterolateral margin, tergite 5 with 2 lateral discal setae and 1 postmarginal seta; epandrium black with central white patches.

Female. Body length 6.3–6.5 mm ( Fig. 22 A). General characters as in male but differing from male in: median part of frons about 1/2 the head-width; frontal vitta with brownish yellow pollinosity; frontal triangle broader than male; vibrissa medium long; genal height about 1/7 of eye height; palpi distinctly spoon-shaped; thorax with yellow pollinosity; legs grey except knees brown; 1/2 basal fore tibia and 1/2 basal hind tabia yellow; fore femur with longer pv than male; mid tibia with 1 submedian ad and pd, without specialized spines; hind femur with 2 preapical av; hind tibia with 1 submedian ad; hind tarsi regular; abdomen without patches ( Fig. 22 C).

Remarks. In contrast with other species from this group, male of L. lanceoseta is distinctively special in: face and antenna short; arista short yet plumose; apex of mid tibia with willowleaf-like av and pv spines; and first hind tarsomere with a sharp and pointy apex, only anterodorsal margin covered with curved bristles. The original yet unused Chinese name of the species is “Hequ liuying”, which is given after its type locality. Now its admitted Chinese name is “Liuye liuying”, which stands for the willowleaf-like spines on mid tibia.

Distribution. China (Shanxi).
