Two new species of Yaginumaella Prószyński 1976 from Yunnan China (Araneae Salticidae)

摘要

The present paper deals with two new species of Yaginumaella, Yaginumaella lushuiensis >sp. n. (female and male) and Yaginumaella pseudoflexa >sp. n. (female and male). The male of Yaginumaella lushuiensis >sp. n. differs from the related species Yaginumaella flexa Song & Chai, 1992 in ventral view of palpal organ. The female of Yaginumaella lushuiensis >sp. n. differs from the related species Yaginumaella urbanii Żabka, 1981 by: 1) hoods locate at the anterior area of epigynum and far away from the copulatory openings; 2) epigynum about circular; 3) copulatory openings transverse. The male of Yaginumaella pseudoflexa >sp. n. differs from the related species Yaginumaella bulbosa Peng, Tang & Li, 2008 in ventral view of palpal organ: 1) basal portion of embolus touches the margin of genital bulb. 2) distal portion of tibial apophysis covers the posterior margin of cymbium and far away from the margin of genital bulb. The female of Yaginumaella pseudoflexa >sp. n. differs from the related species Yaginumaella urbanii Żabka, 1981 by: epigynum about as long as wide; hoods locate at the anterior area of the epigynum, above the outside area of the copulatory openings and far away from the copulatory openings. Photos of body and copulatory organs, line drawings of copulatory organs, as well as the locality map are provided. Descriptions of morphology are given.
