A review of (Araneae, Symphytognathidae).

Wunderlich, 1995 is redefined to include species with six eyes in three diads, chelicerae fused only near the base, sculpturing on the carapace, one or two clasping spurs on tibia II, a bilateral scutum of the male abdomen, and globular spermathecae and adjacent copulatory openings in the female. A key and distribution map are provided for 24 species in this paper. Diagnoses and illustrated photographs are provided for 22 species from China, Malaysia, Thailand, and Vietnam. Thirteen species are described and documented as new to science: Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♀), Y. Lin & S. Li, (♀), Y. Lin & S. Li, (♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♂♀), Y. Lin & S. Li, (♀), and Y. Lin & S. Li, (♀). Three new combinations are proposed: (Lin & Li, 2009), , (Lin & Li, 2009), , and (Lin & Li, 2009), are transferred from Marples, 1951. DNA barcodes and genetic distances of seventeen species are obtained to confirm correct identification. Types of seven known Chinese species are re-examined, and the taxonomic placement of Miller, Griswold & Yin, 2009 may be incorrect based on morphological and molecular data.
