TYPES: Syntypes of Dolichognatha longiceps are deposited in NRM. We did not directly examine the type specimens ourselves. However, to ensure correct determination we have compared our specimens to a digital photograph of the male holotype that was kindly made available by Torbjörn Kronestedt and Gunvi Lindberg, and to the drawings available in the literature .

DESCRIPTION OF THE WEB: Dolichognatha longiceps spins its orb web near the ground at the base of trees. The web that we observed was built between the buttresses of a tree. It is twodimensional with oval shape (fig. 8A) and with a major axis of 40 cm. The web orientation is horizontal with dense spiral turns and numerous radii, without split radii (fig. 8). The web frame is an irregular polygonal shape and has numerous attachment sites (fig. 8A). The hub is closed (fig. 8B) and seems somewhat displaced toward one of the edges.

ADDITIONAL MATERIAL EXAMINED: One male and two females from Thale Ban National Park, Satun Province, THAILAND. N6 ° 42 9 37.0 0, E100 ° 10 9 09.2 0, elev. 270m, 15–18.x. 2003, G. Hormiga leg. In AMNH .
