Material examined. Holotype: Male (IZCAS-Ar 34331), Nepal, Mechi District, Bauwa , Bhanjyang , 27°04’03”N, 87°47’19”E, altitude 2659 m, 26 November 2016, Q. Y. Zhao leg. Paratype: 1 male, same data as holotype (IZCAS-Ar 34332).GoogleMaps 

Etymology. The species name comes from Chinese pinyin “ niuqu  ” which means “irregular”, referring to the wave-shaped conductor of bulb; noun in apposition.

Diagnosis. Males of this new species resemble those of L. zhaoi Li et Li  sp. nov. in having a conductor bifid with different sizes and a retrolateral tibial apophysis on the palp, but can be distinguished by the narrow, waveshaped distal part of the larger one ( Fig. 3A View Figure ) and the shorter retrolateral apophysis on the tibia ( Fig. 3C View Figure ).

Description. Male (holotype): Measurements: Total length 3.46; carapace length: 0.95, width: 1.05; abdomen length: 2.23, width: 1.15. Legs brown; measurements: I 11.39 (3.16, 0.47, 3.40, 2.96, 1.40), II 8.89 (2.81, 0.36, 2.72, 2.19, 0.81), III 6.75 (2.00, 0.31, 1.94, 1.72, 0.78), IV 9.62 (2.60, 0.36, 2.90, 2.48, 1.28). Carapace round, yellow, with one broad middle band and two narrow marginal bands. Anterior margin of thoracic region distinctly elevated. Six eyes. Chelicerae brown. Cheliceral promargin with lamina and one tooth, retromargin with two small teeth ( Fig. 8D View Figure ), the posterior surface of fang with 26 small denticles. Labium brown. Sternum yellow. Abdomen dark and elongate with complex patterns dorsally. Palp ( Figs 3A–D View Figure ): femur slender; tibia with one slightly curved spine and one apophysis bearing a spine retrolaterally; bulb pale yellow, ovate ( Fig. 3A View Figure ); conductor arising distally from bulb, divided into two unequal parts, one sharp and the other distinctly wave-shaped; embolus arising distally from bulb, oblique, slightly sigmoid. Embolus and conductor slightly separated (the distance is less than semidiameter of bulb).

Female: Unknown.

Variation. Males: carapace length: 0.92, 0.95, width: 1.20, 2.23, tibia I 3.16, 3.33.

Natural History. Collected in leaf litter of fragmented montane forest (mixed with tea garden) at an altitude of 2659 m.
