While out searching for subjects, I frequently encounter specimens of
Metacyrba taeniola taeniola hunting for things as well. Unlike the other jumpers I've documented (
Dendryphantinae and
Thiodininae),
M. t. taeniola belongs to the subfamily
Marpissinae. It's a subspecies of
Metacryba taeniola, differentiated from
M. t. similis by range (east vs. west), size (larger), and color (femur IV as dark as other femora). They're busy little spiders, and I enjoy watching them. Like
Hentzia palmarum, their two front legs are long and muscular. The spinnerets are visible. They have an iridescent greenish-orange band under their big black eyes. I believe the chelicerae may be the same iridescent color. As in
Phidippus audax, the male's palps are more swollen than the female's, like boxing gloves.

"Peek-a-boo!" I pressed gently on the siding, hoping to draw him out, and he obliged! |
