Two species of the genusEriovixiafrom southwest China were re-described， i.e.，E.huwenaHan & Zhu， 2010 andE.poonaensis(Tikader & Bal， 1981). The female ofE.huwenaand the male ofE.poonaensiswere described for the first time. Diagnoses， illustrations， and distribution data of the two species were given in this study.

The small to median-sized orb-weaver spider genusEriovixiaArcher， 1951 is characteristized by the combination of the following characters： carapace pear-shaped; abdomen ovoid， subtriangular or polygonal， female of some species having a long “tail” beyond the spinnerets; epigynum linguiform or triangular， arched medially; median ocular area of male situated on an eye tubercle; palpal patella without macroseta. A total of 20 species from Africa and Asia included in the genus (World Spider Catalog， 2016). Yinetal.(1990) described three new species from Yunnan and Hainan province in 1990. Yin and Zhao (1994) described another new species from Hubei province. Four species including a new species from the Gaoligong Mountains， western Yunnan province (Mietal.， 2010) and 6 species including 3 new species from Hainan province (Han & Zhu， 2010) were described in 2010. So far， 14 species have been recorded from China， mainly occurred in south China， especially in Yunnan and Hainan province (Schenkel， 1963; Song， 1987; Feng， 1990; Yinetal.， 1990， 1997， 2012;Chen & Zhang， 1991； Yin & Zhao， 1994; Zhuetal.， 1994; Songetal.， 1999， 2001； Han & Zhu， 2010; Mietal.， 2010).

While examining the specimens collected from Yunnan-Guizhou Plateau， southwest China， 9 species ofEriovixiawere identified：E.cavaleriei(Schenkel， 1963)，E.excelsa(Simon， 1889)，E.huwenaHan & Zhu， 2010，E.laglaizei(Simon， 1877)，E.nigrimaculataHan & Zhu， 2010，E.poonaensis(Tikader & Bal， 1981)，E.pseudocentrodes(B?senberg & Strand， 1906)，E.stictaMi， Peng & Yin， 2010 andE.yunnanensis(Yinetal.， 1990).E.poonaensisandE.huwenawere re-described in this paper， with the female ofE.huwenaand the male ofE.poonaensiswere described for the first time. Diagnoses， distribution data， illustrations of the two species are provided. The specimens are deposited in Museum of Tongren University (MTU).

Material and methods

Specimens are stored in 75% ethanol. The epigynum was cleared in lactic acid for examination. Specimens were examined using an Olympus SZ30 stereo microscope. Digital photographs were taken using a Cannon Powershot G12 digital camera mounted on an Olympus SZX16， compound focus images were generated using Helicon Focus. Leg measurements are given as： total length (femur， patella + tibia， metatarsus， tarsus). All measurements are given in millimeters (mm). Abbreviations used in the text： ALE， anterior lateral eyes; AME， anterior median eyes; MOA， median ocular area; PLE， posterior lateral eyes; PME， posterior median eyes.

(銅仁學院生物與農林工程學院，貴州銅仁554300)

首次報道了虎紋毛園蛛EriovixiahuwenaHan & Zhu， 2010的雌性和浦那毛園蛛E.poonaensis(Tikader & Bal，1981)的雄性。標本保存于銅仁學院博物館(MTU)。虎紋毛園蛛EriovixiahuwenaHan & Zhu， 2010(圖1～6)鑒別特征：該種的體形及斑紋與尖腹毛園蛛E.pseudocentrodes(B?senberg & Strand， 1906)較類似，區別在于：1)該種的頂突呈楔狀，后者的頂突略呈長方形；2)該種的納精囊呈腎形，后者的納精囊呈卵圓形；3)該種的交媾管在靠近納精囊的一端膨大，后者交媾管不膨大。浦那毛園蛛Eriovixiapoonaensis(Tikader & Bal， 1981)(圖7～12)鑒別特征：該種的外形及生殖器與拖尾毛園蛛E.laglaizei(Simon，1877)均有相似之處，區別在于：1)該種的腹部末端沒有尾狀突，后者腹部末端具尾狀突；2)該種觸肢器中突的左、右兩叉約等寬，后者中突的右叉約為左叉的2倍寬；3)該種的納精囊呈球形，后者的納精囊呈卵圓形。
