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). They were originally assigned to Prolochus Thorell, 1895, which was synonymized with Dolichognatha O. Pickard-Cambridge, 1869 by Levi (1981), and reaffirmed by Kallal Hormiga (2018) after a multi-loci phylogenetic analysis.
