Nine new species of jumping spiders from Xishuangbanna Tropical Botanical Garden are described: Euochin yaoi sp. nov. (♀♂), Laufeia banna sp. nov. (♀♂), Marengo tangi sp. nov. (♀♂), Myrmarachne liui sp. nov. (♀♂), Nandicius proszynskii sp. nov. (♂), Phintelloides pengi sp. nov. (♀♂), Poecilorchestes zhengi sp. nov. (♀♂), Rhene wandae sp. nov.

The goal of the present paper is to describe new taxa based on recent specimens collected from
Specimens were collected by fogging and sieving leaf litter in the tropical rainforest of Xishuangbanna Tropical Botanical Garden, Yunnan, China, which were preserved in 75% ethanol for morphological study. All specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences (

The specific name is a patronym in honor of Prof. Zhiyuan Yao (Shenyang, China), one of the collectors of the new species; noun (name) in genitive case.
The male of Euochin yaoi sp. nov. resembles that of E. subwanyan (Wang & Li, 2020) in having a flat embolus and oval bulb, but it can be easily distinguished from the latter by the retrolateral tibial apophysis, which is about 1.5× longer than wide and acutely narrowed to a pointed tip distally in retrolateral view, and by the shorter embolus (Fig.
Male (Figs

Epigyne (Fig.
Known only from the type locality in Yunnan, China.
The species is placed in this genus based on the flat embolus, the dense, long, white setae on the proximal half of the cymbium and distally on the male palpal tibia (mostly missing in the holotype), and the copulatory ducts are markedly shorter than the spermathecal diameter; these characters are unique to Euochin species (
Laufeia aenea Simon, 1889 from Japan.
Holotype
♂ (
The species name is derived from the name of the type locality; noun in apposition.
The species closely resembles that of L. aenea Simon, 1889 in having a branched embolic projection and medially inflated copulatory ducts, but it differs in having: 1) the embolus longer than the tooth of the embolic base in ventral view (Fig.

The species name is a patronym in honor of Dr. Guo Tang, one of the collectors of the new species; noun (name) in genitive case.
The male of Marengo tangi sp. nov. closely resembles that of M. batheryensis Sudhin, Nafin, Benjamin & Sudhikumar, 2019 by the similar abdominal markings and retrolateral tibial apophysis but differs by the following: 1) the process of the embolic disc is conspicuous in retrolateral view (Fig.
Female paratype and male holotype of Marengo tangi sp. nov. A epigyne, ventral B vulva, dorsal C holotype habitus, dorsal D lateral E female paratype habitus, dorsal F holotype carapace, frontal G holotype left chelicera, posterior H holotype leg I, prolateral. Scale bars: 0.1 (A, B, G); 0. 5 (C–E, H); 0.2 (F).

Although not collected together, the male and female are considered to be conspecific because they share a very similar habitus.
Myrmarachne melanocephala MacLeay, 1839 from India.

The specific name is a patronym in honor of Mr. Hong Liu (Tongren, China), one of the collectors of the new species; noun (name) in genitive case.
The male of Myrmarachne liui sp. nov. closely resembles that of M. cornuta Badcock, 1918 in having a similar habitus and palpal structure, but it differs by the following: 1) the second embolic coil is almost 2/3 the bulb width (Fig.
Female paratype and male holotype of Myrmarachne liui sp. nov. A epigyne, ventral B vulva, dorsal C holotype habitus, dorsal D lateral E ventral F female paratype habitus, dorsal G holotype left chelicera, posterior H female paratype left chelicera, posterior.

Phintella mussooriensis Prószynski, 1992 from India.
Holotype
♂ (
The species name is a patronym in honor of Prof. Jerzy Prószyński (Warsaw, Poland), who has made significant contributions to the taxonomy of salticid spiders; noun (name) in genitive case.
Nandicius proszynskii sp. nov. can be easily distinguished from any congeners by the presence of a disto-retrolateral femoral apophysis and a short retrolateral tibial apophysis, which is shorter than the dorsal tibial apophysis vs. lacking a femoral apophysis and with a retrolateral tibial apophysis longer than the dorsal tibial apophysis.

The species name is a patronym in honor of Prof. Xianjin Peng (Changsha, China), who has made significant contributions to the taxonomy of Chinese salticids; noun (name) in genitive case.
The new species resembles Phintelloides versicolor (C. L. Koch, 1846) and Phintella leucaspis (Simon, 1903) in the copulatory organs, but it can be easily distinguished by the straight embolus (Fig.

Epigyne (Fig.

The male and female are considered to be the same species because they were collected from the same site without other candidates and have copulatory organs similar to Phintelloides versicolor. Phintella leucaspis (Simon, 1903) shares a very similar palp with Phintelloides versicolor and the new species, thus it most likely belongs to Phintelloides.
Poecilorchestes decoratus Simon, 1901 from New Guinea.
Holotype
♂ (
The species name is a patronym in honor of Prof. Guo Zheng (Shenyang, China), the collector of the new species; noun (name) in genitive case.
The male of Poecilorchestes zhengi sp. nov. resembles that of P. logunovi Prószyński & Deeleman-Reinhold, 2013 in having a square carapace bearing scales and a similar palp, but it can be easily distinguished by the visible retrolateral tibial apophysis and the thicker sperm duct with a maximum diameter almost half of bulb width in ventral view (Fig.

The species is temporarily placed into Poecilorchestes due to its general resemblance to P. logunovi Prószyński & Deeleman-Reinhold, 2013. Further data are required to confirm the placement of this species.
Rhanis flavigera C. L. Koch, 1846 from Indonesia.
Holotype
♂ (
The species name is a patronym in honor of Prof. Wanda Wesołowska (Wrocław, Poland), who has contributed significantly to the taxonomy of the genus Rhene; noun (name) in genitive case.
The new species can be easily distinguished from any congeners by the coiled embolus which is longer than the bulb vs. embolus markedly shorter than the bulb, straight or curved in other species.

The male of Simaetha cheni sp. nov. resembles that of S. menglun Wang & Li, 2020 by the similar palp, but it can be easily distinguished by the following: 1) the embolus is slightly curved into a blunt tip directed anteriorly in ventral view (Fig.
