Finally! Back with another #ScienteaficABC 😁The next in my alphabetical journey through all 128 (currently, anyway) spider families is ANAPIDAE! This family of diminutive spiders contains 58 genera/231 species as of now. (images: Conoculus lyugadinus by Akio Tanikawa, CC)
They occur worldwide, but mostly S. America, Africa, Asia & Australia/NZ. A few species are found in Europe and North America as well. (Image: Micropholcomma sp. by tjeales on iNat, CC)
Interestingly, Anapidae have either 6 or 8 eyes, with the posterior median pair being either reduced in size or totally absent. They do not exceed around 2mm in body length so, as a family, are very small. (Image: Micropholcomma sp. tjeales on iNat, CC)
They have a modification to the carapace giving them a characteristic raised ocular area. They are tiny (<3mm long), w/ rounded or hunched abdomens & quite short legs. They have a light covering of hairs & some species have spines on their legs & even abdomen. (img: tjeales iNat)
An interesting feature that some species exhibit is the presence of hardened, shell-like dorsal &/or ventral scutes on their abdomen, which are useful in identification. You can see more images including some that show these scutes here:
