Machimus erythocnemius
(Hine)
The pupal case of female
M. erythocnemius
was described by
Scarbrough & Kuhar (1995)
based on specimens from the
United States
National Museum. They indicated that the pupal cases are similar to
M. paropus
,
but have wider spacing between the second and third posterior antennal processes. Abdominal segment 1 has 11 or 12 spurs. Segments 2–7 have alternating long spurs and short spines, and segment 8 has 6 "setae."
M. paropus
pupal cases have spaces between the posterior antennal processes that are equal or subequal. Abdominal segment 1 has 10 dorsal spurs. Long dorsal spurs alternate with pairs of short spines on segments 2–7, and segment 8 has only 2 dorsomedian bristlelike processes.
