Takachihoa is similar to Synaema Simon 1864, but differs from the latter in that the female epigynum is weakly sclerotized and bears no chitinized plates, and the ventral tibial apophysis of male palp is large and securiform (Ono 1988).
Body medium to large; elongated-oval strongly convex; head vertical; clypeus with broad anterolateral emarginations; gena never extending on to eye; mandible large with bifid apex; maxillary palp long terminal segment with dorsal margin strongly produced weakly securiform; pronotum convex anteriorly never excavated anterolaterally.
