(Pls 1E, 3–5E, 7E; Fig. 7)
Diagnosis. Arista almost bare, though sometimes with 1 or 2 dorsal, minute branches (Pl. 4E). First and 2nd tarsomeres of male foreleg dorsodistally extended, with sex-combs: 1 st tarsomere with a longitudinal row of ca. 29 black, apically blunt teeth along entire length and a distal cluster of ca. 10 black, apically sharp teeth; 2nd tarsomere with a distal cluster of ca. 8 black, apically sharp teeth (Fig. 7A,B). Cercus ventrally tapered, with a fringe of 11 spines on apicoventral margin (Fig. 7C,D,F). Paramere flat, somewhat blade-shaped, only slightly curved ventrad, apically sharp and broader, subapically with 1 acute, dorsal, somewhat membranous process bearing 1 sensillum at apex (Fig. 7H–L). Gonopods shorter than aedeagus, dorsoapically with long, acute process (Fig. 7J). Spermathecal capsule not wrinkled horizontally, without apical indentation (Fig. 7O).
Description (♂, ♀). Head (Pls 1E, 3–5E, 7E): Frontal vitta, fronto-orbital plate, ocellar triangle, face, facial carina, and gena yellowish brown; fronto-orbital plate somewhat paler than frontal vitta. Occiput dorsally yellowish brown, ventrally dark brown. Postgena yellowish brown, dark brown along margin of occiput. Antennal pedicel yellowish brown; 1 st flagellomere pale grayish yellow. Supracervical setulae 19¯21 per side; postocular setae 17–18 per side. Palpus pale yellowish brown. Clypeus yellowish brown. Cibarium with 18–23 medial and 17–19 posterior sensilla per side. Prementum with 5 (1 proximal, 2 lateral, and 2 distal) pairs of setae.
Thorax (Pl. 1E) yellowish brown. Postpronotal lobe pale yellow. Acrostichal setulae in 6 regular rows. Mid katepisternal seta distinctly longer than those below it.
Legs (Pl. 1E, Fig. 7A,B): Fore- and midleg 1 st tarsomeres longer than total length of 4 succeeding tarsomeres.
Abdomen (Pl. 1E): Tergites entirely yellow, somewhat glossy.
Male terminalia (Fig. 7C–L): Epandrium dorsally broadened, only caudomedially pubescent, with ca. 15 long setae per side; ventral lobe not elongated, triangular in lateral view. Cercus entirely pubescent, setigerous (but number of setae uncountable due to bad conditions of dissected organs long preserved in glycerin). Surstylus with a row of ca. 15 prensisetae on caudal margin and ca. 51 setae on ventral portion of inner surface. Tenth sternite broken. Hypandrial caudolateral lobes unpubescent. Aedeagus apically slightly bent ventrad, medially to basally membranous, sheathed with gonopods; apodeme apically broadened in lateral view, shorter than aedeagus.
Female terminalia (Fig. 7M–O): Tergite VIII yellow, pubescent except for anteromedial margin, caudodorsally swollen in lateral view. Epiproct and hypoproct yellow. Oviscapt valve apically triangular in lateral view, with ca. 14 marginal and ca. 85 minute, lateral ovisensilla. Spermathecal capsule hemispherical, nearly as broad as long; introvert about 1/2 height of capsule, horizontally wrinkled.
Measurements (in mm): BL = 3.65 in holotype (range in 3♀ paratypes: 3.45̄3.85), ThL = 1.50 (1.40̄1.65), WL = 3.30 (3.25̄3.35), WW = 1.35 (1.33̄1.38).
Indices. FW/HW = 0.48 (range in 3♀ paratypes: 0.46̄0.50), ch/o = 0.28 (0.25̄0.28), prorb = 1.20 (1.00̄1.38), rcorb = 0.33 (0.28̄0.38), vb = 0.29 (0.25̄0.33), orbito = 0.77 (0.67̄0.83), dcl = 0.67 (0.65̄0.70), sctl = 1.30 (1.21̄1.45), sterno = 0.40 (0.38̄0.42), dcp = 0.50 (0.44̄0.56), sctlp = 1.13 (1.06̄1.19), C = 4.77 (4.39̄5.00), 4c = 0.50 (0.49̄0.51), 4v = 1.53 (1.43̄1.59), 5x = 1.57 (1.25̄1.70), ac = 1.99 (1.90̄2.11), M = 0.43 (0.38̄0.45), C3F = 0.53 (0.39̄0.58).
Holotype. ♂ (#06060), Dandang Park, Gongshan County, Yunnan, China, 22.vi.1993, W.X. Zhang (KIZ).
Paratypes. CHINA: 2♀ (#06061, #06062; KIZ), 1♀ (SEHU), same data as holotype.
Etymology. From a combination of the species name “ miki ” and Greek word “oides” (meaning “resembling miki ”), referring to the large, longitudinal row of sex-comb resembling those in the L. miki group.
Distribution. China (Yunnan).
Remarks. This species clearly belongs to the L. denticeps group in light of the diagnosis, but has quite particular sex-combs, which are also seen in the succeeding two new species, L. kimurai sp. nov. and L. anthophilia sp. nov.
