Abstract:A new Lysiteles species, L. fanjingensis sp. nov. (♀), and the unknown male of L. nudus Yu & Zhang, 2017 from Guizhou Province of China are described. Color photographs and plot drawings of diagnostic characters are provided. All specimens are deposited in the Museum of Tongren University, Guizhou Province, China.
Lysiteles fanjingensis sp. nov. (Plates Ⅰ, Ⅱ, Ⅴ: C-F)
Type material: holotype , Huguosi, Fanjing Mountain National Nature Reserve (108.669 436°E, 27.914 813°N, 1 994 m), Guizhou Province, 14 June 2019, Cheng Wang & Jiahui Gan leg. Paratypes 13♀, same date as holotype.
Etymology: the species name is derived from the name of type locality; adjective.
Diagnosis: the new species resembles those of L. saltus Ono, 1979 (see Ono, 2001: 220, figs. 36-43) in male palp having 2 tibial apophyses (the retrolateral one obviously longer than the ventral one), short embolus less than 1/3 cymbial width, and in female epigyne having foliiform atrial membrane anterior-medially, but differs in: (1) retrolateral tibial apophysis slightly curved medially in ventral view versus straight in L. saltus; (2) ventral tibial apophysis longer and terminally curved towards inner side in ventral view versus straight in L. saltus; (3) embolus curved medially and its tip directed towards 02∶30 o'clock in ventral view versus straight and its tip directed towards 04∶00 o'clock in L. saltus; (4) atrial membrane of epigyne wider than length versus almost equal to the length in L. saltus; (5) copulatory ducts short, the diameter larger than its length versus less than the length obviously in L. saltus.
Genitalia: Male palptibia wider than length, with 2 apophyses, ventral apophysis stout, curved terminally, retrolateral apophysis heavily sclerotized, thumb-shaped and distally blunt; cymbium flat; bulb almost round, with sperm duct extending along the margin; embolus sclerotized, originating at 11∶00 o'clock position of bulb, slightly curved medially and with pointed tip directed towards 02∶30 o'clock in ventral view. Epigyne with a transparent and foliiform atrial membrane wider than length, located anterior-medially; copulatory openings indistinct, located at the anterior part of the atria, covered by the lateral side of the atrial membrane; copulatory ducts short, its diameter larger than length; spermathecae spherical, the distance between them about 1/3 their diameter.
Lysiteles nudus Yu & Zhang, 2017 (Plates Ⅲ, Ⅳ, Ⅴ: A-B)
L.nudus Yu & Zhang, 2017: 73, figs. 4-6 (Df).
Material examined: 23♀, Xiangshuiyan, Leigong Mountain National Nature Reserve (108.159 833°E, 26.362 245°N, 1 204 m), Guizhou Province, 1 May 2018, Guijie Tian and Hong Liu leg.
Diagnosis: Female diagnosed by Yu & Zhang (2017). The male resembles those of L. niger Ono, 1979 (see Tang et al., 2008: 26, figs. 13a-k) in palp having flat embolus, 2 tibial apophyses (the retrolateral one slightly longer than the ventral one), but differs in: (1) ventral tibial apophysis widest at base in ventral view versus widest at terminal in L. niger; (2) embolus slightly curved terminally in ventral view versus straight in L. niger; (3) ventral tibial apophysis wider than retrolateral tibial apophysis in retrolateral view versus narrower than retrolateral tibial apophysis in L. niger.
Genitalia: Female well described by Yu & Zhang (2017); male palp tibia wider than length, with 2 apophyses, ventral apophysis digitiform, retrolateral apophysis heavily sclerotized, distally folded; cymbium flat, widest medially; bulb almost round, with sperm duct extending along the margin; embolus flat, originating from the anterior edge of the bulb, widest at base, slightly curved terminally.
