Five new species of salticids were collected from China: Synagelides emangou Liu, sp. nov. (♂, ♀) from Gansu province, and S. jinding Liu, sp. nov. (♂), S. serratus Liu, sp. nov. (♂, ♀), S. shuqiang Liu, sp. nov. (♂), and S. triangulatus Liu, sp. nov. (♀) from Jiangxi Province. All species are described and illustrated with photographs and SEM micrographs, and their distributions are also mapped.
Ant-like, Gansu Province, Jiangxi Province, Jumping spider, taxonomy
The family Salticidae, or jumping spiders, is the most diverse spider family worldwide. It consists of 6368 species in 659 genera (
When examining spider specimens collected from Qinghai, Gansu, Hebei, Shanxi, and Jiangxi provinces, five new Synagelides species were identified, and they are described here: Synagelides emangou sp. nov., S. jinding sp. nov., S. serratus sp. nov., S. shuqiang sp. nov., and S. triangulatus sp. nov.
Specimens were examined using a Zeiss Stereo Discovery V12 stereomicroscope with a Zeiss Axio Cam HRc. Both the male palps and female copulatory organs were dissected and examined in 80–85% ethanol. The vulvae were cleaned in pancreatin. All the specimens were photographed with an Olympus CX43 compound microscope with a KUY NICE CCD (Beijing Tiannuoxiang Scientific Instrument Co., Ltd, China). For SEM photographs, the specimens were dried under natural conditions, sprayed with gold with a small ion-sputtering apparatus ETD-2000 (Beijing Yilibotong Technology Development Co., Ltd, China), or used without coating, and photographed with a Zeiss EVO LS15 (Carl Zeiss AG, Germany) scanning electron microscope. Images were edited using the ImagineView software package and the Smart SEM User Interface.
All measurements were made by using a stereomicroscope with AxioVision SE64 Rel. 4.8.3 software and are given in millimeters. Leg measurements are given as the total length (femur, patella, tibia, metatarsus, tarsus). Specimens were put in separate bottles with a collection number and a serial number, such as 20200504-1, sp6. Holotype and paratype are labeled by red and yellow cards, respectively. All specimens are deposited in the Animal Specimen Museum, College of Life Science, Jinggangshan University (ASM-JGSU).

The male of this species is not conspecific with the female of Synagelides triangulatus sp. nov. for the following reasons. Firstly, the male abdomen has the two pairs of white stripes medially (vs a pair of spots and one chevron-shaped yellowish stripe in S. triangulatus) and the arch-shaped yellowish stripe located subposteriorly (vs absent in S. triangulatus).

The male of this species is not conspecific with Synagelides triangulatus sp. nov. based on the following observations. Firstly, the male abdomen is elongated in dorsal view, nearly 2.5 times as long as wide, while in S. triangulatus, the length–width ratio is ca 1.5. Secondly, the abdomen has a clear constriction located medially (Fig.
