R. China; 2School of Life Sciences, Sichuan University, Chengdu 610064, China Abstract. Three new species of the family Anapidae are reported from caves and tropical rainforest of southern China: Gaiziapis encunensis, Minanapis menglunensis and Sinanapis longituba. The genus Minanapis is recorded for the first time from China. Keywords: Anapid, tropical rainforest, cave spiders, taxa The family Anapidae was erected by Simon (1895). Anapid copulatory duct; Cm 5 cymbium; CO 5 copulatory opening; members are small (usually less than 3 mm in body length), Co 5 conductor; DS 5 dorsal scutum; EF 5 epigynal furrow; three-clawed, ecribellate, haplogyne, cryptozoic spiders with Em 5 embolus; FA 5 femoral apophysis; FD 5 fertilization six or eight eyes situated on an elevated ocular region. They duct; Fe 5 femur; LS 5 labral spur; MA 5 median apophysis; usually live in leaf litter and moss on the rainforest floor and PA 5 patellar apophysis; Pa 5 patella; POG 5 postgenital build orb webs with a diameter of less than 3 cm (Murphy plate; S 5 spermatheca; Ti 5 tibia; Tu 5 tegulum and VS 5 et al. 2000). Some also inhabit caves. This family was redefined ventral scutum. by Platnick and Shadab (1978, 1979). Platnick and Forster (1989) supposed that the labral spur and the glandular TAXONOMY openings at anterolateral corners of the carapace were two Family Anapidae Simon 1895 synapomorphies for the family Anapidae. Genus Gaiziapis Miller, Griswold & Yin 2009 The family Anapidae includes 38 genera and 150 species Gaiziapis encunensis new species (Platnick 2011), distributed in tropical and southern temperate Figs. 1–3, 10 regions, such as Central and South America, Australia and Southeast Asia.

The Diagnosis.—The new species is similar to G. zhizhuba in present paper deals with three new Chinese species of the sharing the following characters: a deep anteromedian family Anapidae based on material collected in Guangxi, invagination on the dorsal scutum (Fig. 1B), lack of a Yunnan and Hainan. prolateral apophysis on the palpal bulb and having a much more complicated pedipalp with more membranes and METHODS sclerites (Fig. 2B) in the male, the absence of pedipalp in the Specimens were examined using a Leica M250 C stereomi- female and a round, rather than triangular, abdomen from croscope. Further details were studied under an Olympus dorsal view (Figs. 1B, D). It can be distinguished from G. BX51 compound microscope. All drawings were made using a zhizhuba by a triangular median apophysis (Figs. 1I, 2B) and drawing apparatus attached to an Olympus BX51 compound an apical apophysis with coarse veins on the male palpal bulb microscope, and then inked on ink jet plotter paper. Male (Figs. 1H, 2A), absence of tufty denticles on the tegulum palpi and female genitalia were examined and illustrated after (present in G. zhizhuba: Figs. 60A, 61A,C) in the male, and by they were dissected from the spiders’ bodies.
