Portion between
these two thickenings slightly constricted
and surface striation broken, resembling
arthrodial membrane but more rigid;
mesofemur and basifemur jointed in a
different way: broken striae absent and
internal thickenings forming S-shape in
paraxial view (Fig. 3A, th.pa., paraxial
thickenings; th.an., antiaxial thickenings);
basifemur with one long, flagellate
trichobothrium, mesofemur and telofemur
each with five setae. Genu relatively short,
with one paraxial solenidion and eight setae,
ventral setae much thicker and longer.
