Type material.

Holotype ♂: China: Jiangxi Province: Wuyuan County, Lianhua Cave, N29°29'02", E117°36'53", 350 m, 4.XII.2016, X. Zhang; Paratypes: 3♀ 2♂, same data as holotype; 3♀, the same locality, N29°29'02", E117°36'53", 352 m, 20.V.2013, Y. Luo and J. Liu.

Etymology.

The species is named after Mr. Nathaniel Gist Gee. Mr. Gee was an American biologist who lived in China about 35 years. He contributed greatly to the development of biological research and education in China, including the establishment of the first biology department in the history of university education in China ( Fu 2016). He collected the holotype of L. kulianganus .

Diagnosis.

The male can be distinguished from all other Longicoelotes species by its long cymbial furrow, about 1/3 length of cymbium (vs 1/4 or 1/5 in other species) (Figs 1, 3; Wang 2002: figs 312-314). The female differ from all other Longicoelotes species by the nearly heart-shaped atrium and large anterior parts of copulatory ducts, subequal to receptacles (vs nearly triangular atrium and small anterior parts in L. kulianganus , about 1/2 diameter of receptacles; nearly rounded atrium and extremely small anterior parts in L. senkakuensis , about 1/4 diameter of receptacles) (Figs 2, 4-5; Shimojana 2000: figs 46-49).

Carapace greenish, with black lateral margins, the radial grooves distinct. Abdomen yellow, with blackish herringbone patterns. Palp as in Fig. 1: patellar apophysis long, about 2 times longer than tibia; tibia short, about 1/5 length of cymbium; cymbial furrow long, about 1/3 length of cymbium; ventral tibial apophysis as long as tibia, without pointed tip, extending beyond the tibia; conductor slender and bifurcated; posterior tip of conductor bifurcated; anterior tip of conductor bifurcated, ventral part sharp, dorsal part lamellate; median apophysis reduced; embolus beginning at 5:30 o’clock position.
