In the past year, Prof. Jian Chen conducted several spider collections in Hubei Province. Almost 1000 spiders were collected. After diagnosis, two of them were found to belong to the genus Sinopoda Jäger, 1999.
Two Sinopoda Jäger, 1999 species, both from Hubei Province, including one new species, are treated in the current paper: S. angulata Jäger, Gao & Fei, 2002 and S. yichangensis sp. n. (♂). The male of S. angulata is described for the first time from Enshi Tujia and Miao Autonomous Prefecture, Hubei Province. New geographic records are provided as well as photos of the copulatory organs and habitus.

The genus Sinopoda was established by Jäger (1999), with Sinopoda forcipata (Karsch, 1881) as its type species. Currently, Sinopoda is the fourth most speciose genus of the subfamily Heteropodinae Thorell, 1873, and includes 126 species (
Specimens were examined and measured with a Leica M205C stereomicroscope. Points arising from the tegular appendages are listed as clock-positions from the left bulb in ventral view. Male palps were examined after dissection and detached from the spiders’ bodies and the epigynes were examined and illustrated after dissection. Epigynes were removed and cleared in warm lactic acid before illustration. All photographs were taken with a Leica DFC450 digital camera attached to a Leica M205C stereomicroscope, with 10–20 photographs taken in different focal planes and combined using image stacking software (Leica LAS). Photographic images were edited using Adobe Photoshop CC 2015. Left palps are illustrated. Most hairs and macrosetae are omitted in the palp drawings. All specimens are deposited in the Centre for Behavioural Ecology and Evolution, College of Life Sciences, Hubei University, Wuhan, China (CBEE).
Leg measurements are shown as: total length (femur, patella, tibia, metatarsus, tarsus). The number of spines is listed for each segment in the following order: prolateral, dorsal, retrolateral, ventral (in femora and patellae, ventral spines are absent and the fourth digit is omitted in the spination formula).
