A new species of the genus Sinanapis Wunderlich & Song (Araneae, Anapidae) from China.

Anapidae are small-sized (~ 3 mm), three-clawed, haplogyne spiders with six or eight eyes situated on an elevated ocular region and an anterior labral spur. The family currently contains 38 genera and 153 species worldwide (Platnick 2013, Lin, Li & Jäger, 2013). Nine species belonging to six genera have been recorded from China (Oi, 1960; Brignoli 1981; Zhang & Chen, 1994; Wunderlich & Song, 1995; Ono, Chang & Tso, 2006; Miller, Griswold & Yin, 2009; Lin & Li, 2012). The genus Sinanapis was established by Wunderlich & Song (1995) to accommodate the new species S. crassitarsus from China. Later, S. thaleri Ono, 2009 and S. lingituba Lin & Li, 2012 were described from Vietnam and China respectively; but in 2013, S. thaleri was synonymized with S. crassitarsus by Lin, Li & Jäger (2013). While examining spider specimens from the Wuyi Mountains (southern China), we found one male specimen of a new species of Sinanapis. This new species is here described as Sinanapis wuyi. All measurements given in the text are in millimeters. The specimen is preserved in 75% alcohol and was examined, drawn, and measured under a Leica M165C stereomicroscope equipped with an Abbe drawing device. Photographs were taken using a Leica M205A stereomicroscope equipped with a DFC450 CCD. The specimen is deposited in the Museum of Hebei University (MHBU), Baoding, China.
