Dolichognatha bannaensis new species, a six-eyes tetragnathid spider from China (Araneae, Tetragnathidae).

Almost all of the tetragnathid spiders have eight eyes, while two Dolichognatha species, D. longiceps (Thorell, 1895) (Sunil Jose 2014: 474, figs 1A-B) and D. junlitjri (Barrion-Dupo Barrion, 2014) (Barrion-Dupo Barrion 2014: 196, figs 1A-B) have six eyes (PME absent).

First record of Artoria Thorell, 1877 (Araneae: Lycosidae) from Malaysia, with the description of a new species.

The wolf spider genus Artoria Thorell, 1877 is a common group in Australasia, currently including 41 species from Australia, three from New Zealand and four from Pacific islands (Framenau Baehr 2018; Word Spider Catalog 2019). This does not, however, comprise the whole distribution of the genus. The type species, A. parvula Thorell, 1877 has been recorded from China, Philippines, Indonesia (Sulawesi) and Australia (Northern Territory). An endemic species, A. ligulacea (Qu, Peng Yin, 2009) was described from Yunnan, China. This indicates that there must be some undescribed species from Southeast Asian countries. A recent collecting expedition to Malaysia confirms this hypothesis. Two species of Artoria were found, the type species, A. parvula from East and West Malaysia and a new species, A. weiwei sp. nov. from East Malaysia. In this study, we illustrate the former and describe for the first time the latter species.

The male of Yaginumaella lushuiensissp. n. differs from the related species Yaginumaella flexa Song & Chai, 1992 in ventral view of palpal organ. The female of Yaginumaella lushuiensissp. n. differs from the related species Yaginumaella urbanii Zabka, 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 pseudoflexasp. 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 pseudoflexasp. n. differs from the related species Yaginumaella urbanii Zabka, 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.
