Praestigia
Praestigia is a genus of sheet-weaving spiders (family Linyphiidae) described by Alfred Frank Millidge in 1954. The genus is distinguished by a unique male cephalic projection bearing a detachable cap composed of interconnected fibers bound with a waxy substance. Eight species are recognized, distributed across boreal and arctic regions of the Northern Hemisphere. The etymology combines Latin 'prae' (before/in front) and Greek 'stigios' (awl), referencing this distinctive projection.
