Opopaea
goblin spiders
Opopaea is a large genus of minute goblin spiders in the family Oonopidae, containing approximately 180-190 accepted species. These spiders are characterized by their extremely small size (under 2 mm), six-eyed arrangement, and reddish-brown coloration. The genus is one of the most species-rich within the Oonopidae family, with representatives found across multiple continents including Australia and Sri Lanka. Species in this genus inhabit leaf litter and forest floor habitats, where their diminutive size and cryptic coloration make them difficult to detect.
Scytodidae
Spitting spiders
Scytodidae, commonly known as spitting spiders, are a family of haplogyne spiders characterized by their unique prey capture mechanism: projecting sticky venom from their fangs to immobilize prey. The family contains over 150 described species in several genera, with Scytodes being the most diverse and widespread. These spiders possess enlarged venom glands that produce a glue-like substance which solidifies into elastic threads upon contact, binding prey to surfaces. Some species exhibit social behaviors including communal egg guarding and cooperative prey capture, while others are solitary. They are found worldwide in tropical and temperate regions, with several species associated with human habitations.
Segestriidae
Tube-dwelling spiders, Tunnel spiders
Segestriidae is a family of tube-dwelling spiders comprising two large and widespread genera (Segestria and Ariadna) and two smaller genera (Citharoceps and Gippsicola). Members are easily recognized by having six eyes arranged in a semicircle (rather than the typical eight eyes of most spiders) and the first three pairs of legs arranged forward (rather than two). These morphological features appear to be adaptations for living in silken tubes or burrows. The family has a global distribution across all continents except Antarctica, with greatest diversity in tropical and subtropical regions. The genus Ariadna alone contains 102 of the 127 described species in the family.
