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
.
Fig. 12. Unambiguous synapomorphies of
Dolichognatha
and sister taxa mapped over the consensus tree from analyses of the complete matrix (
A
) and when
A. quinquemucronata
is not included in the analyses (
B
). All changes in the Metainae lineage depicted in this figure are homoplasious, thus marked with white circles.
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.
