摘要
沼科Elipsocidae我国香港曾记载一种,Elipsocus oligotricuhus Thornton,1959,上科Epipsocidae台湾记载一种,Epipsocus hageni Banks,1937,共2种。华立中(1987)记载有3种,其中把香港的Elipsocus oligotricuhus分放于两个科的两个属中,同时Epipsocus hageni为N.Banks 1937记述,并非1917。本文记述了采自宁夏、陕西的沼科1新属2新种(均为短翅雌虫);云南的上科1新种,至此我国两科共5种。
The present paper describes one genus and 2 species of Elipsocidae and one species of Epipsocidae from China, all of them are new to science. Type specimens are kept in the Insect Collection of Beijing Agricultural University.Family Elipsocidae Genus Sinelipsocus gen. n.Females micropterous. Antenna 13-segmented. Ocelli present. Fourth segment of maxillary palp elongate, with rounded apex. Fore wings nearly subopaque without strong pattern; setae on veins and wing margins, stout and long, R, M+Cu1a and A with 2 rows of setae, Cu2 glabrous; Rs and M meeting in a point or fused for a short length, M 2-branched, AP smaller. Hind wing reduced to small lobes, margin setose, shorter. Tarsi 2-segmented, pulvillus broad, expanded apically, basitarsus with ctenidiobothria. Subgenital plate bilobed; gonapophyses with dorsal valve apically divided into a large fleshy lobe internally and a small pointed external apophysis; external valve somewhat rectangular, lightly sclerotised, margin with setose. Ventral valve pointed.Distribution: Shaanxi and Ningxia, China.The new genus is similar to Antarctopsocus and Grahcaecilius, but differs from them in having three ocelli, M 2-branched, pterostigma broad and long, R, M+Cu1, A with 2 rows of setae, hind wing margin with setae.1. Sinelipsocus villosus, sp. n. (Fig.1)Holotype (?), Guyang Co. (1850m), Ningxia Hui Aut. Reg. 17-Ⅶ-1980; paratypes 3 (?) (?) , same place as holotype (1 (?), Ⅶ-12, 2 (?) (?) , Ⅶ-17).The new species differs from Sinelipsocus yangi sp. n. by the pterostigma longer and broader, R4+5 near M1 and subgenital plate sclerotization nearly horizontal and external valve square.2. Sinelipsocus yangi, sp. n. (Fig. 2)Holotype (?), Zhouzhi Co., Shaanxi Prov., 14-Ⅷ-1962.This new species differs from the above species in the R4+5 far away from M1 pterostigma shorter and external valve nearly rectangular.Family Epipsocidae3. Epipsocus formosus, sp. n. (Fig. 3)Holotype (?) , Ruili Co., Yunnan Prov., 4-Ⅴ-1981.The new species is similar to Epipsocus atratus New 1980, but differs from the latter in body length (to tip of folded wing) 3.85 mm (Epipsocus atratus only 2.80 mm), M3 forked near Rs fork; it also resembles the Epipsocus hageni Banks from Taiwan, but is distinguishable from it by the forewing brown without markings and body smaller (E. hagen 5 mm).
