The present paper deals with 18 species of spiders collected from farmlands and orchards in Guangxi. Of them, five are new species, two are newly recorded in China. The diagnoses of these new species are given below. All specimens are deposited in Hebei Educational College. 1. Achaearanea rostra Zhu et Zhang, sp, nov(Fig. 1) Holotype♀, Fengshan County (24°30′N, 107°00′E), September, 1981; allotype♂, Fengshan County, November, 1981. Female: Total length 7.2 mm. Cephalothorax 2.6 mm long, 1.8 mm wide; abdomen 5.5 mm long, 4.0 mm wide. Male: Total length 3.7 mm wide. Cephalothorax 1.72 mm long, 1.68 mm wide; abdomen 2.05 mm long, 1.98 mm wide. The new species resembles Achaearanea galeiforma Zhu et al., 1991, but differs from the latter in lacking a tubercle on the dorsum of abdomen as well as in the structures of epigynum and male palp. 2. Chrysso lingchuanensis Zhu et Zhang, sp. nov. (Fig. 2) Holotype♀, Lingchuan County(25°24′N, 110°18′E), May, 1990. Female: Total length 1.43 mm. Cephalothorax 0.5 mm long, 0.5 mm wide; abdomen 1.0 mm long, 0.75 mm wide, 0.9 mm high. The new species resembles Chrysso pulcherrima (Mello-Leitao, 1917)in the shape ofabdomen, but differs from the latter in having a lip-shaped projection at the base of epigynum, and six feather-shaped spines near the tip of abdomen. 3. Coscinida asiatica Zhu et Zhang, sp. nov. (Fig. 3) Holotype♀, allotype♂, paratype 1♀2♂♂, Nanning City(22°48′N, 108°18′E), April, 1987. Female: Total length 1.9 mm. Cephaiothorax 0.73 mm long, 0.62 mm wide; abdomen 1.2 mm long, 0.85 mm wide. Male: Total length 1.79 mm. Cephalothorax 0.67 mm long, 0.67 mm wide; abdomen 1.1 mm long, 0.65 wide. The new species differs from any other species of Coscinida in having a cone-shaped projection on clypeus. 4. Enoplognatha diodonta Zhu et Zhang, sp. nov. (Fig. 4) Holotype♀, Yangshuo County (24°2′N, 110°24′E), January, 1987, allotype♂, Hechi City (24°42′N, 108°00′E), May, 1987; paratype 2♀♀, Quanzhou County(25°54′N, 111°00′E), August, 1987. Female: Total length 9.4 mm. Cephalothorax 3.4 mm long, 2.7 mm wide; abdomen 6.5 mm long, 5.0 mm wide. Male: Total length 5.9 mm. Cephalothorax 3.3 mm long, 2.5 mm wide; abdomen 4.1 mm long, 2.5 mm wide. The palpal organ of this new species resembles that of Enoplognatha deserta Levy, (1981), but differs from the latter in the long tibia, and the strctures of palpal organ and epigynum. 5. Theridion transiporum Zhu et Zhang, sp. nov. (Fig. 5) Holotype♀, Tianyang County(23°42′N, 106°54′E), September, 1980; paratye 1♀, Laibin County(23°42′N, 109°12′E), May, 1982. Female: Total length 3.66 mm. Cephalothorax 1.08 mm long, 1.06 mm wide; abdomen 2.7 mm long, 2.24 mm wide. The new species is similar to Theridion diadematum Chrysanthus(1963), but differs from the latter in the longer coputatory tube and the spermathecae being at the base of vulva.
