Type species

Microdipoena guttata Banks, 1895 by original designation; type locality Long Island, New York, USA.

Diagnosis

The male can be distinguished from other mysmenids by there are two or three distal-prolateral macrosetae on the tibia I (Figs 3A, 8A, 11A, 15A, 21B). The palpal bulb is very large (at least 4–5× tibia in size, 2–3× in other mysmenids). The cymbium has an apical part with complex structure, which specialized as a cymbial conductor and a cymbial process (Figs 6H, 9C, 12B, 16B, 22D). A lobe-shaped paracymbium bears several long setae along its edge (Figs 4C, 6H, 9B, 12B, F, 16B, 20D, 22D). The thick embolus folds into a twisted complex structure at distal end, wrapped by a membranous structure on the apex of cymbium (Figs 9A–C, 12D–G, 16C–G, 20D, E, 22A, F–H) (except in M. comorensis, M. elsae, M. guttata, M. mihindi, M. nyungwe, and M. vanstallei, without complex structure, but with either a distal apophysis or irregular membrane). The female differed from other mysmenids by the abdomen with a whitish ventral ring around the spinnerets (Figs 3F, 11E, 19D, 21F) (except M. comorensis, with all ventral abdominal area paler). The shape of spermathecae are mostly round, oval, or semicircular, wrapped by membranous copulatory ducts from posterior or around (Figs 7C, 9F, 10F, 13C, 14F, 17C, 18F, 23D).
