Pear-Shaped Leucauge Spider (Opadometa fastigata), Sumatra Indonesia

Photos in this post were taken in Bengkulu Sumatra Indonesia. This spider has the common name of pear-shaped leucauge. Even it is using word Leucauge that directs us to the genus of Leucauge, this spider is not under that genus. It is under genus of Opadometa which is the same family to Leucauge in the family of Tetragnathidae (Long-jawed Orb Weavers).
The color of abdomen is black with silver white marks. The shape of abdomen is broaden posteriorly and extended anteriorly overlapping the carapace that forming a hump-like shape. The legs is black with some yellow bands. At the fourth legs there are curved fine hairs at the femur (too bad my camera didnot record it very well at the above photo) and thick brush of spines at the tibia.

At its web, this spider stays upside down. Photos above were taken from beside of  its web, so, in order viewing it easily, i have rotated the images 180 degree.
